This is one of the never-ending questions out there, catamarans vs. monohulls (also known by some just as sailboats). The discussions are wild and are, many times, really hard to follow unless you’re already a vivid sailor. By then, you probably already have your own opinion on what the differences are.

In this post, I’m trying to take a little more pragmatic approach to describe the 9 most important differences that I think you should know about.

Table of Contents

1. Catamarans Have Two Hulls, Sailboats or Monohulls Have One

This is the most apparent feature that strikes you when you look at the two boats next to each other; one has two hulls, and the other only one. Mono, as you might know, means one (1).

Having two hulls also implies you need something that connects them, making the boat look a little bit like a manta ray, or is that only me?

2. Monohulls Will Rock From Side to Side

Catamarans don’t heel (leaning to its side in boat language). Therefore, they offer a very different sailing experience, which is more stable and usually more comfortable; this also applies when staying at anchor. The catamaran will move around with the wind, always staying flat, while the sailboat will rock from side to side and might even get you seasick .

This is especially noticeable when the wind is opposing the waves, making the boat have the wind pushing it from one side and the waves banging it from the other side. This makes for a very uncomfortable anchorage on a monohull. Basically, you are the iron, and the wind and wave are your hammer and anvil, not a perfect place to be.

3. Catamarans Offer More Space for the Same Length

For the same length of boat, let’s say 40ft, you’re getting a lot more space on a catamaran. This is due to the two hulls, but also the big deck that attaches the hulls. There will also be even more space on the outside of the boat, both fore and aft of the mast. In between the bows, you will have either a solid deck or trampolines , which will greatly increase the space.

4. Catamarans Make Horrible Noises While Sailing Upwind

The distance between the water surface and the deck’s underside is called bridge deck clearance ; if it is not big enough, even small waves will start smashing into the underside.

This repeated cycle of waves hitting the boat does induce not only great noise but also a lot of vibrations and discomfort to the crew.

This problem is something that just doesn’t exist on monohulls (only one hull) and also is a strong argument from those who prefer monohulls.

The noise might not be a big deal when traveling coastal waters for a few hours a day, but consider going days on end straight into the wind, hearing that banging noise, ad a little motion sickness, and you will pretty soon wish you were on a monohull 🙂

5. Monohulls Are Slower Than Catamarans

At least that is the short answer, this applies if we only compare the length of the boat, but if we compare the total length in the water, it’s a different story. Much of this speed comes from the decreased drag, bigger sails, and a catamaran’s lesser weight.

Here are some articles when you want to better understand catamaran speed:

6. Catamarans Offer Less Helm Feedback

One big benefit of having a boat that heels is that it’s a great way to get feedback on whether or not the boat is overpowered. Since a catamaran stays flat, it is harder for a new captain to understand when to reef.

This could be a safety issue for those transitioning from monohulls to catamarans, which I believe is the most common way people acquire a catamaran.

7. Monohulls Are Harder to Dock

For a monohull to turn, it needs enough water passing around the rudder; for enough water to pass around the rudder, the boat needs to be moving. So this means once you stop your boat, you can’t turn; the things that move you are the wind and the current. This is the tricky part with a monohull, the timing needs to be perfect, or you’ll either go too fast and hit the dock, or you’ll go too slow and drift away.

On a catamaran, that’s different, you see; now you have two engines, much like a battle tank, you can now make a 360 turn on the spot. This means you can do a full stop, put one engine in forward and one in reverse, making the boat spin on its axis. That’s great! I wish my car would do that.

8. Catamarans Are More Fuel-Efficient

Saying a catamaran is fuel-efficient is like saying your Ford F150 truck is fuel-efficient. But, in comparison to its one-hull brother, it’s true, this really needs a lot more explanation for it to be a fair comparison, but only considering the lengths of the boat, the catamaran will consume less fuel.

This is mostly a consequence of the less drag a catamaran has since the weight is distributed over a greater area.

9. Catamarans Offer More Comfort

Since catamarans have more space and don’t heel as much, they offer a more comfortable experience. One beautiful aspect of having a big deck is that you can hang out in the trampolines; they are basically two big hammocks, and since hammocks already are great, putting them on a boat makes them awesome.

And since it doesn’t heel, you can also freely move around on the boat without spilling your drink or being at risk of falling overboard. This also means that going inside to cook is a treat since you don’t have to cook while trying not to fall over.

Looks and Other Factors

All in all, catamarans are great, but so are monohulls; there are also many other factors that I haven’t mentioned yet; these are mainly factors of the heart.

Many people feel that it isn’t real sailing if it isn’t done like it was in the good old days, heeling over and all. And to some extent, I can totally agree with that, but on the other hand, enjoying those two trampolines while on a sunny weather cruise down the bay is something I can’t forget.

And also the looks, catamarans look great; I think they look and almost move like those manta rays you can see down in the Bahamas. On the other hand, there is not much cooler than seeing a solid old monohull dig deep into the waves and go almost straight into the wind; what a feeling!

Catamaran: Impresses with a wide footprint, enhancing onboard living space and comfort. The challenge lies in marina space during peak seasons, offset by the freedom to enjoy extended periods aboard without the need for frequent shore visits.
Sailboat: Navigates marinas with ease due to its narrower profile. While confined space might limit interior room, the sailboat's ability to find berths becomes advantageous during bustling harbor seasons. It's worth noting that this characteristic can vary depending on the model; for instance, new models such as the Bavaria C38 or the Dufour 44 (premiered in Düsseldorf and soon available) feature generous beams, providing more space, especially in the main front bedroom, and creating a general feeling of larger spaces, even on the deck.

4. All on the Same Level:

Catamaran: Integrates the dinette and cockpit seamlessly, creating a harmonious, unified space with a transparent sliding wall. Visual continuity fosters a connected and inclusive experience among guests.
Sailboat: Embraces a more compartmentalized layout, allowing for distinct areas that cater to different activities. This provides passengers with varied environments throughout the vessel.

5. Manoeuvrability:

Catamaran: Exhibits impressive maneuverability, thanks to two engines that facilitate precise control in tight spaces. The ability to turn within its own axis is particularly advantageous in crowded harbors.
Sailboat: Requires careful and deliberate maneuvering in harbors due to its single engine. While agility might be reduced, the sailboat's sailing capabilities shine when navigating open waters.

6. Speed and Sailing:

Catamaran: Hydrodynamically efficient hulls offer superior speed, especially in upwind sailing conditions. The catamaran excels in providing a swift and enjoyable journey, minimizing the impact of adverse weather.
Sailboat: Demonstrates versatility in sailing conditions, adapting well to upwind challenges. While not as inherently fast as a catamaran, the sailboat's overall speed ensures an engaging sailing experience.

7. Comfort on Board:

Catamaran: Appeals to first-time sailors seeking a home-like experience. Offers disengaged and domestically oriented spaces, ensuring privacy between hulls—a valuable feature for those with varying daily routines or sailing with a skipper or children.
Sailboat: Fosters a more communal atmosphere, ideal for passengers who enjoy close interaction. The sailboat's compact layout promotes shared experiences among travelers.

8. Autonomy:

Catamaran: Slightly compromised autonomy due to weight sensitivity. Limited fuel independence and water reserves necessitate more thoughtful planning. The presence of two engines enhances maneuverability, allowing for precise navigation.
Sailboat: Excels in fuel autonomy, providing extended sailing periods without the need for frequent refueling. A single-engine simplifies maintenance and promotes straightforward, self-sufficient voyages.

9. Organisation of Space:

Catamaran: Typically designed with a standardized layout, catamarans for charter often feature two cabins in each hull, strategically positioned at the extreme bow and stern. This layout, with two bathrooms centrally located, offers a consistent and practical accommodation setup. Innovative models feature an exterior galley integrated into the cockpit, providing a unique blend of space and functionality.
Sailboat: Boasting a more versatile structure, sailboats come in various layouts to cater to diverse preferences. Modern designs challenge traditional constraints with generous beams. This not only enhances interior space, especially in the main front bedroom but also creates a broader and more open atmosphere on the deck. The flexibility in cabin arrangements allows for a personalized and comfortable sailing experience, accommodating different preferences and needs. Ultimately, the organization of space on a sailboat is influenced by the specific model chosen, allowing for a tailored approach to onboard living.

Catamarans excel in rough seas, thanks to their twin-hull design providing enhanced stability and reduced heeling compared to monohull sailboats. The unique architecture allows for increased speed and maneuverability, making them efficient in navigating challenging conditions.

Key to their rough-sea capabilities is the bridge deck —the space between the hulls—featuring ample clearance in well-designed catamarans. This minimizes slamming, enhances seaworthiness by reducing structural stress, and ensures a smoother ride in turbulent sea states.

While catamarans can capsize in extreme situations, proper design, operation, and the skill of an experienced captain contribute to their overall capability in handling a variety of sea conditions, ensuring a secure and enjoyable sailing experience, even in rough seas.

A sailing catamaran and a power catamaran differ primarily in propulsion . A sailing catamaran relies on sails, offering a traditional experience with stability and efficiency. In contrast, a power catamaran uses engines, emphasizing speed and ease of handling. Power catamarans are chosen for faster cruising and covering more miles.

Catamarans are often considered faster than monohull sailboats due to their hydrodynamic design . With two hulls providing stability, reduced drag, and a wider beam for efficient sailing angles, catamarans excel in speed. However, sailboats showcase versatility, excelling in certain conditions such as upwind sailing. Overall speed comparison depends on various factors, including design and wind conditions.

Sailing a catamaran is often seen as less challenging for beginners due to inherent stability and reduced heeling. The dual-hull design provides balance, making catamarans forgiving in terms of capsizing. While novices appreciate stability, adjustments are needed for maneuvering and handling increased windage. Proficiency comes with practice, and experienced sailors may find catamarans offer a refreshing change in sailing dynamics.

Short Answer

A sailboat is a type of boat that is propelled by the force of the wind on sails that are mounted on one or more masts.

A catamaran is a type of sailboat that is characterized by two hulls that are connected by a frame.

While both types of boats are propelled by sail, catamarans are wider and more stable than sailboats, making them better suited for recreational sailing.

Additionally, catamarans usually have more space for passengers and are generally faster than sailboats.

Sailboat Basics

Sailboats come in a variety of shapes and sizes, from small dinghies to large sailing yachts.

They are powered by the wind and use a sail to capture the energy of the wind and propel the boat forward.

The sail is attached to a mast that is usually made of wood or aluminum and is raised above the deck of the boat.

Sailboats also have a deep keel that helps to stabilize the boat and keep it pointing in the right direction, even in windy conditions.

The keel also helps the boat to sail upwind and enables it to tack, or turn, in the wind.

Sailboats typically have a single hull, which makes them faster and more efficient than catamarans.

Catamaran Basics

Catamarans are a type of boat that has quickly become popular in recent years.

Catamarans typically feature two parallel hulls that are connected by a frame, and they often have more deck space and living space than traditional sailboats.

They also have the advantage of being more stable in the water due to their wider design, and they are also able to navigate shallow waters much more easily.

Catamarans are often powered by either a motor or sails, and they are generally more comfortable and spacious than traditional sailboats.

However, they are not as fast as sailboats due to their wider hulls.

When shopping for a catamaran, it is important to consider the size, weight, and the number of cabins available.

It is also important to consider the type of materials used in the construction of the vessel, as well as the type of propulsion system that will be used.

Catamarans come in a variety of sizes and designs, and it is important to choose one that will suit your needs.

It is also important to consider the cost and the maintenance requirements of the vessel, as well as the availability of parts and service.

Lastly, it is important to consider the safety features of the catamaran.

Catamarans generally have more stability than traditional sailboats, but they can still be susceptible to capsizing if not handled properly.

It is important to make sure that the vessel is equipped with the necessary safety equipment, such as life jackets, flares, and a reliable communication system.

Overall, catamarans are an excellent choice for sailing enthusiasts who want the comfort and space of a larger vessel, but still want the stability and maneuverability of a smaller vessel.

With careful consideration of size, weight, propulsion system, and safety features, a catamaran can be an excellent choice for sailing enthusiasts of all levels.

Advantages and Disadvantages of Sailboats

When it comes to advantages and disadvantages of sailboats, there are a few things to consider.

Sailboats are generally faster than catamarans due to their single hull design, which gives them a streamlined shape that cuts through the water more efficiently.

This also makes them ideal for racing and long-distance sailing.

Additionally, sailboats tend to be more maneuverable than catamarans, making them easier to control in tight spaces.

However, there are a few disadvantages to sailing on a sailboat as well.

One of the main drawbacks is the lack of space compared to catamarans.

Since sailboats have a single hull, they usually have less storage space and fewer cabins than catamarans.

Additionally, sailboats are more prone to capsizing due to their deep keel, which makes them less stable than catamarans.

Finally, sailboats can be more expensive to purchase and maintain than catamarans due to the specialized equipment and materials required.

Overall, sailboats have their own advantages and disadvantages, so its important to weigh them carefully before making a decision.

While sailboats may be faster and more maneuverable than catamarans, they also tend to be more expensive and lack the spaciousness and stability that catamarans offer.

Advantages and Disadvantages of Catamarans

Catamarans have a number of advantages over sailboats, and are quickly becoming one of the most popular types of sailing vessels.

Catamarans boast a number of unique benefits that make them appealing for many different types of sailors.

The main advantage of catamarans is their stability.

Due to the two parallel hulls, catamarans are able to stay level in the water, even in choppy or windy conditions.

This makes them ideal for those who want to stay comfortable while sailing.

Additionally, the dual hulls of a catamaran make them much more spacious than sailboats and provide plenty of room to move around and store extra items.

Catamarans also have the advantage of being able to navigate shallow waters that sailboats would find difficult or impossible to pass through.

This makes them great for exploring coves and rivers that are off the beaten path.

Additionally, the lack of a keel means that catamarans can be easily beached and stored on shore.

However, there are also some disadvantages to catamarans.

One of the main drawbacks is that they are typically much slower than sailboats.

This is due to the fact that the two hulls have more drag in the water than the single hull of a sailboat.

Additionally, catamarans are more expensive than sailboats, as they require more materials and labor to build.

Overall, it is important to consider both the advantages and disadvantages of sailboats and catamarans before deciding which type of vessel is right for you.

While both types of vessels have their own unique benefits, it is ultimately up to you to decide which one will best suit your needs.

Comparing Sailboats and Catamarans

When it comes to comparing sailboats and catamarans, there are several distinct differences that can help you decide which type of vessel is right for you.

Sailboats typically have one mast and a deep keel that helps to stabilize them in the water.

This makes them faster than catamarans, as the keel creates a more efficient hydrodynamic shape for the boat to cut through the water.

Catamarans, on the other hand, have two parallel hulls and no keel, making them more stable and able to easily navigate shallow waters.

Catamarans are also wider than sailboats, which allows for more space and comfort for cruising.

Making the right decision is essential to ensure you have the best experience possible when you book with sailyachts.com. So that you do, we’ve designed this guide to break down sailboats vs catamarans to assist you with your decision-making.

What Is the Difference Between a Sailing Catamaran and a Sailboat?

Catamarans and sailboats are two very different types of vessels when you consider the way they’re made, their features, and how they perform on water.

Before you make any concrete decisions about a catamaran or a sailboat with Sailyachts .com, you should be aware of the differences between them as well as the similarities.

Sailboat VS Catamaran

Differences, size and space.

Catamarans are much more sizable than sailboats; they’re often equipped with more cabins, have various bathrooms scattered throughout the boat, and the sailor’s cabin tends to be bigger on them, too. As for the interiors and living space, they provide more, too, with expansive kitchens and communal zones; they’re practically floating House.

Whereas, if you look at our sailboats, they’re Usually smaller, offering a cozier feeling, and the cabins are rather compact compared to what you’d find on a catamaran. That’s why they’re extremely popular among couples hiring a yacht with us.

If you’re after stability, catamarans will be better suited for you due to their two hulls, which protect the vessel from tilting when it hits heavy waves out in the Mediterranean. Additionally, they don’t have any deep keels and ballasts which protects the boat from struggling in shallow waters and adds an extra layer of steadiness.

Sailboats only have one hull, so they’re prone to tilting more when they encounter waves. They need a deep keel and ballast to keep things balanced. Unfortunately, this makes sailing in shallow areas a bit more difficult and puts the boat at more risk of rocking. However, if you like a bit of action, you might enjoy it.

Versatility

Since catamarans have two engines, it makes them easier to maneuver, especially in tight areas, making visits to hidden locations less of a hassle. However, depending on the model, the size may impact how versatile it is.

When you’re operating a sailboat, you better be prepared for measured controls and timed movements because of their limited ability because of their single engine.

The one thing all sailors want to know is how fast their boat will be. Catamarans are faster than sailboats since they have a hydrodynamic design, which is particularly favorable when sailing upwind.

Sailboats aren’t exactly slow; they are just catamarans that are a lot faster and more powerful. So, even if you hire one, you’ll still have the chance to live out your James Bond moment.

Similarities

The sails on both catamarans and sailboats are similar. On both types of vessels, the sailor will need to use the sails in the same way to leverage the power of the wind to move the ship when it’s in the ocean.

So, if you’ve only sailed one type before, you’ll be easily able to understand how the sails on the other work.

Rudders are one of the main components needed for a ship to be able to steer its course. Catamarans and sailboats have them in order for the captain to be able to go in the direction they want. However, they must be operated in line with the sails, so the captain must carefully coordinate the angle of the rudder with the trim of the sails.

Pros and Cons of Sailboats and Catamarans

Advantages and disadvantages of sailboats.

They require less fuel, making your sail more cost-effective than it would be on a catamaran.
Sailboats are more affordable to rent for a week with sailyachts.com than catamarans.
They provide a classic sailing experience paired with an exhilarating adventure.
Compared to catamarans, they’re easier to anchor.

Disadvantages

If you’ve no sailing experience, they can be hard to operate.
Bumpier out at sea than catamarans.
They’re more difficult to sail in shallow waters.
They’re better suited to smaller groups since they’re less roomy, and the cabins tend to be more compact.

Advantages and Disadvantages of Catamarans

They offer much more luxury amenities than sailboats, such as large communal areas, sunbathing space, etc.
They tend to provide extra space and additional cabins.
Easier to operate if you’re a first-time sailor.
Sailing with a catamaran gives an extra layer of stability in the ocean, so the ride is less bumpy.
Catamarans are faster than sailboats.
Catamarans are more expensive to hire with sailyachts.com for a week than sailboats.
It’s harder to find an available catamaran since they’re more popular.
With a catamaran, it can be difficult to find somewhere to anchor during the high season since they’re larger and take up more space.

How Much Does a Sailboat Cost Compared to a Catamaran?

While prices of both types of boats vary based on the time of year you book your rental and where you pick it up, catamarans are the priciest option.

The minimum you’d pay for a catamaran is around €4000 per week during the low season. If you wanted to hire one during the high season, it could cost more than €10000 per week.

Our sailboat prices are much more affordable than catamarans; for one week, you can find a rental for as low as €2,000 a week throughout the low season, but if you want to hire it during the high season, the prices can go up over €6500 per week.

Be aware that these fees are without any crew members. If you’ve no sailing experience or don’t have a valid license, you’ll need a captain onboard, which costs €220 each day. Additionally, adding extra crew members to take care of the day-to-day operations on the ship will cost an extra €170 each day for every member.

Catamaran vs Sailyacht: Which One to Choose?

As you can see, our catamarans and sailboats offer two very different but exciting experiences for customers.

Small parties, such as couples or groups of friends, tend to enjoy sailboats more because of the intimacy they provide. It’s a more authentic sailing trip; imagine crashing against the waves in a traditional monohull, where it’s just your nearest and dearest, alone without disturbance.

Catamarans are winners for bigger groups like families. They’ve got so much more space and cabins, and the level of luxury that comes with them is unmatched. You’ll feel like a true VIP on one of our catamarans when you’re sailing along the French Riviera, catching waves alongside the rich and famous.

Final Words

So, that’s our analysis of the battle between sailboats and catamarans. Now, the decision is up to you, which one will you go with? Is it going to be an easy-to-manage sailboat or a luxurious catamaran with lots of space and extra comfort?

If you’re still unsure which option is best for you, you can contact one of our team members today on our Contact Us Page, and we will go through both of the options with you in depth to find the right solution.

Due to their stability, catamarans are seen as an easier sailing option than sailboats. There's much less of a chance of you capsizing in one than a sailboat. However, if you've enough experience, taking on the challenge of operating a sailboat can be an exhilarating and fun experience.

Anyone who prefers a smooth sail rather than a bouncy outing should opt for a catamaran. Their dual hulls, combined with minimum heeling and wide base, work well with providing sailors and passengers a calm voyage. But remember, if you do end up finding yourself in choppy conditions, there's only so much these things can do for you, so always take care when you're in the ocean.

There's no right or wrong option when it comes to sailboats and catamarans. It's more about the type of sailing experience you're after and how big the group that's joining you for your trip is. Catamarans are better for multi-day trips with family and friends to faraway picturesque islands. They're comfortable, stable, and often come with modern features and facilities, but they're also the most expensive option of the two. Those who don't mind a bit of rocking from time to time and aren't overly fussed about the level of comfort will prefer sailboats. Avid sailors, in general, prefer sailboats because operating them is more of a challenge, which adds an element of excitement to the adventure. Along with that, they're also cheaper and are more readily available at the ports we operate out of.

What Is A Catamaran Sailboat? (And What It Looks Like)

What Is A Catamaran Boat? (And What It Looks Like) | Life of Sailing

August 30, 2022

Catamarans are increasingly popular for sailing and commercial use, but what sets them apart from monohulls and other multihulls?

A catamaran is a twin-hull boat with two equally-sized hulls placed side by side. They’re powered by engines, sails, or both—and they’re known for efficiency and speed. Catamarans are the most common kind of multihull boat.

In this article, we’ll go over the characteristics of catamarans and how to differentiate them from other types of boats. Additionally, we’ll cover the advantages and disadvantages of catamarans and compare them to trimarans and monohulls. We’ll also go over the most common types of catamarans and their uses.

We sourced the information in this article from marine design guides, boat identification resources, and the online boating community.

Table of contents

‍ How to Spot a Catamaran

Spotting a catamaran is easy. Simply look at the hulls and count them. Catamarans have two hulls side by side and a relatively large gap between them where you can see light on the other end. Catamarans are distinct from trimarans, which have an additional hull between the two outer hulls.

How do Catamarans Work?

The principle behind the catamaran is simple. You can think of catamarans like cars and monohulls like motorcycles. Catamarans distribute their weight between hulls on either side, whereas monohulls utilize only one hull.

Evidently, cars are much more difficult to tip over and can hold much more weight. Additionally, cars are wider, as they have much more contact with the road. Catamarans work in a similar way, as they have a wide stance and contact with the surface on both sides.

Obviously, that isn’t the most precise comparison. But the basic principle is the same, and catamarans have a few notable benefits over monohulls.

Catamaran Vs Monohull

Catamarans are easy to distinguish from monohulls. A monohull is just a regular old boat with a single hull. The vast majority of boats and ships are monohulls. Catamarans have two hulls, which are usually sleek and narrow.

Here are some comparisons of catamarans and monohulls, along with the advantages twin-hull designs have over most single hull types.

Benefits of Catamarans

Catamarans have numerous benefits. The first is speed. Catamarans produce less drag than monohulls and thus can achieve excessive speeds both under sail and power. They don’t need to plane like monohulls to achieve these high speeds, and they use less fuel.

Catamarans are also much more stable than monohulls. They have a wide stance and shallow draft, and many waves and swells can travel between the hulls instead of below them. This effectively reduces an entire axis of movement and prevents catamarans from rolling excessively.

Drawbacks of Catamarans

Catamarans aren’t advantageous in every way, or else we wouldn’t bother building monohulls. The disadvantages of catamarans limit their use to niche commercial applications and high-end yachts. But what are the drawbacks of a twin-hull design?

Sailing catamarans don’t follow many of the traditional boat handling rules and characteristics that sailors pass down for generations. Some, such as hull speed limitations, are good to do away with—while others, such as responsiveness, are not.

Catamarans aren’t as quick to the helm or responsive as monohulls. There are some exceptions to this rule, but for the most part, you’ll get a lot more feedback from a single-hull vessel. Additionally, the large section of deck between the hulls of a catamaran is prone to pounding in rough seas, which is loud and uncomfortable.

Catamarans can sometimes be twice the width of an equivalent monohull sailboat, which can increase mooring fees and limit docking options.

The final major drawback of catamarans is a consequence of their stability. Traditional full-keel monohull sailboats have a very low center of gravity, which makes them roll in heavy seas but ensures a recovery.

Catamarans have a higher center of gravity, and they can’t right themselves after a knockdown. And though catamarans are less likely to roll, a severe list on a multihull is a much more serious concern than on a ballasted monohull.

Catamaran Vs Trimaran

Catamarans and trimarans are often lumped together, but they have very different design and performance specifications. Trimarans have three hulls, whereas catamarans have two.

Trimarans look a lot like catamarans from the side, but a quick glance at the bow or stern can set them apart. Trimarans are faster than catamarans, as they distribute their weight across three hulls instead of two. This helps them stay centered and reduces interference from pitching and rolling.

Catamarans are fast, but they lose out to trimarans when going head to head. However, catamarans are much less expensive to build and maintain and often have roomier cabins due to their larger hulls.

Types of Catamarans

There are numerous types of catamarans, and their uses vary widely. The catamaran is one of the oldest and most useful hull types, and some variants have been used for thousands of years. Here are the most common kinds of catamaran boats and their uses.

Sailing Catamaran

Sailing catamarans are probably what you think of when you hear the name. Sailing catamarans are sailboats with two identical hulls connected by a center deck. The largest sailing catamarans are spacious and stable vessels that are capable of serious offshore sailing.

Sailing catamarans have a number of notable advantages over monohulls. Monohulls, which are traditional sailboats with a single hull, are limited by a simple concept called hull speed. As the bow and stern wave of a monohull intersect, they cause drag which limits the top speed of the boat.

Catamarans are not bound by hull speed limitations, as they have two hulls. Catamarans can go twice or even three times as fast as similar monohulls and achieve excellent travel times.

Catamarans are also more stable than monohulls, as their wide stance and shallow draft reduce the effect of rough water. They don’t heel, as the force of the wind is counteracted by the double hulls. Additionally, modern sailing catamarans can ‘wave pierce’ by cutting through swells instead of riding over them.

Sailing catamarans come in many shapes and sizes. Small sailing catamarans, such as those used in races and regattas, are known for their speed and relative stability compared to light racing monohulls. Sometimes, they feature a smaller second hull for stability—these are called outriggers.

Sailing catamarans have spacious interiors thanks to the large cockpit between the hulls. This cockpit usually contains cooking and eating spaces, a place to sit, and a hallway between the hulls. The hulls usually contain living quarters and often mirror each other.

Power Catamarans

Power catamarans have an even greater variety than sailing catamarans. These vessels are used for everything from party platforms to ferries and patrol boats.

Power catamarans are a recent development, as engineers and marine architects now realize they have numerous hydrodynamic advantages over other hull types.

Catamarans are much more efficient than other hull types, as they have less drag relative to their size. Additionally, you can build a much larger catamaran with less material. This makes them popular for car and rail ferries, as builders can construct a very wide vessel with two small hulls rather than a narrower vessel with a large single hull.

Military and Commercial Catamarans

Even the military has found a use for the catamaran hull shape. The Spearhead class EPF is an expeditionary fast transport vessel designed for carrying capacity and speed. It has two sharp hulls and a huge cargo capacity.

The Spearhead class EPF is 337 feet long, which is about the same length as a WW2 escort destroyer. Yet despite having a similar length and displacement, these catamarans can travel more than twice as fast—43 knots, or nearly 50 miles per hour. Their great speed is a direct consequence of their catamaran hull type.

Power catamarans are also used as patrol and utility boats on a much smaller scale, with either outboard or inboard motors. The State of Texas uses catamarans to patrol shallow rivers and lakes. Texas Game Wardens utilize state-of-the-art aluminum catamaran patrol boats, which are fast enough to outrun most fishing boats.

There’s another form of power catamaran that you may not have considered. Pontoon boats are technically catamarans, and they’re enormously popular on lakes and rivers throughout the country. Pontoon boats aren’t known for speed, but they’re a great platform for a fun and comfortable outing.

Catamaran Houseboats

The final common type of power catamaran is the two-hulled houseboat. Houseboats don’t always use the catamaran hull type, but it’s common enough that most major manufacturers offer it as an option.

Catamaran houseboats have a few notable advantages over monohull designs. For one, they’re easier to build—especially when pontoons are chosen. Additionally, they’re better suited for navigating shallow water. These vessels can support more weight across their two hulls, offer increased stability, and they’re also efficient.

Why Aren’t Catamarans More Common?

With all the advantages listed in this article to consider, it may seem strange that the use of catamarans is still somewhat limited. At the end of the day, it comes down to economics—as monohull boats and ships are simply cheaper to build.

Additionally, catamarans have some distinct limitations. Monohulls have lots of storage space in their hulls and can carry thousands of tons of cargo safely in all weather conditions. Catamarans lack this space and low center of gravity, so they’re not ideal for transporting cargo past a certain point.

Additionally, monohulls work, and many people are reluctant to experiment with new designs when old designs work just fine. This rule applies to both large and small boats.

A large monohull sailboat can be constructed at low cost from stock plans and reliably sail almost anywhere. Very little complex structural engineering is involved, and looser tolerances reduce cost and maintenance requirements.

I've personally had thousands of questions about sailing and sailboats over the years. As I learn and experience sailing, and the community, I share the answers that work and make sense to me, here on Life of Sailing.

Catamaran vs. Monohull: We Changed, Should You?

There are two schools of thought when it comes to monohull versus catamaran . We have done extensive cruising and lived aboard two monohulls and four catamarans over the past 25+ years . We experienced the good and the bad for both single hull and multihulls first hand. Quite honestly, the pluses for catamarans far outweigh the minuses. There are multiple benefits of catamarans. They are faster, more stable and spacious, and have shallower drafts allowing safer anchorage closer to shore. Being on a stable platform with no heeling cuts down on crew fatigue and seasickness leaving the crew more alert and in control of the vessel. Even novice sailors feel more confident on catamarans.

When we built our monohull Royal Salute in the early 90s, catamarans were not established and were looked upon with extreme suspicion by most cruisers, including ourselves. “Safety and the capsize” issue were always the first things to come up against sailing catamarans. It is a fact that monohulls can get rolled in heavy seas but will right themselves because of the heavy lead keel, and while crew and vessel will be battered, the roll is survivable.

However a catamaran once capsized, will remain upside down (jokingly referring to this state of the catamaran as “reaching its most stable position when upside down”). The inability of a catamaran to self-right was and still is a major bone of contention. However, what is not often discussed is that a monohull has about a 5,000 pound keel of lead that is constantly trying to drag the boat to the bottom of the ocean versus a catamaran that has no ballast and is in most cases with modern catamarans, unsinkable.

So the options are to either sail the world on a boat that, if it springs a leak, will sink like a stone or a vessel that cannot self-right in the event of a capsize but will not sink no matter what. So from a practical point of view, here are our observations over the last 25+ years of living aboard, on the advantages and disadvantages of a catamaran.

ADVANTAGES OF A CATAMARAN

1. speed equals safety.

The speed of a catamaran makes it possible to outrun bad weather. While catamarans do not point as high into the wind as a monohull (or if it does, it makes more leeway or slides sideways), it is about 20% faster than a monohull. This means that even if you sail upwind at a slightly wider angle to the wind than a monohull and have to cover more distance, you will still arrive at your destination long before a monohull.

A modern performance catamaran with daggerboards and good quality sails will point as high as a similar sized monohull. It will point the same as a comparable monohull and sail much faster and therefore arrive at an upwind position much sooner than a the monohull. It is important to note that most of the production catamarans on the market are under-powered and are equipped with standard smaller sails. In lighter breezes many of these designs perform poorly unless fitted with bigger headsails, a Code Zero and a square-top mainsail.

While we believe that more comfortable and safer in rough weather , we have to concede that when the weather gets really bad (60 knots of wind or more) we would personally prefer to be on a monohull from the standpoint of surviving. I would say that a monohull is preferable for serious offshore single-handed sailing because you can more easily hove-to in a monohull. We have been in some extreme weather on a number of catamarans and never really felt that we were in danger, although it takes some nifty seamanship.

A monohull could capsize in extreme weather or even roll in a storm, but they generally come back upright. A catamaran on the other hand, will not right itself. But the cat will generally stay afloat, offering a good place to survive while you wait out the storm or until help comes along. Well-designed modern catamarans are very hard to capsize though.

Having said all that, most catamarans can do 200 to 250 miles a day and with modern technology allowing one to pull down weather at will, there is no good reason why you should get caught in extreme weather. A faster boat is a safer boat as it will in many cases be able to outrun bad weather. With good weather routing information a catamaran can avoid most serious weather and, at worst, place itself in the most favorable position to avoid the brunt of a storm.

2. A Catamaran is a Stable, Safe Platform Underway

Catamarans have no ballast in the keels like monohulls do and therefor it relies on beam and buoyancy for stability. Typically cruising catamarans will have a beam to length ratio of roughly 50%, although many designs nowadays exceed the 50% rule of thumb. So, a 45-ft long catamaran will be about 22-ft wide, providing a very stable platform when sailing. Unlike catamarans, monohulls cannot overcome the rolling and pitching with their narrow beam and the lead ballast for stability.

This rolling and pitching makes the deck on a monohull very unsafe whereas on walking around on the deck of a catamaran while underway is far easier since the boat is much more stable, and it doesn’t heel. This makes sail changes and reefing much easier and a lot safer for the crew. Without the rolling and pitching motion, the danger of falling overboard on a catamaran is considerably less than on a monohull.

3. Crew Fatigue Reduces on a Catamaran

Because a catamaran does not heel over like a monohull, it offers far more comfort underway because the motion is mostly fore and aft pitching and very little beam-to-beam rolling. On all points of sail, a catamaran tracks upright and significantly reduces crew fatigue and seasickness. Seasickness is usually caused by things like anxiety, fatigue, hunger and cold, which all add to a sense of disorientation. This leads the crew to making bad decisions and seamanship errors that could be fatal to the crew and vessel. The more stable platform of the catamaran will hugely keep those issues at bay, making the crew more alert and energized.

Every action and chore including cooking is much easier on a catamaran when underway. It is much more pleasant to be on the deck level looking out rather than being stuck “down below.” It is also much nicer to sleep on a boat that doesn’t heel. I remember nights at sea in our monohull when I was rolling around in my bunk unless I was properly wedge in a little corner. That is simply not the case on catamarans.

All these factors ensure that your crew will not expend unnecessary energy to simply try and stay upright, onboard and safe on a long passage. Your crew on a catamaran will be well rested and alert and will be able to function well if a stressful situation arises.

4. Comfort at Anchor

Catamarans provide a wide platform and therefore offer lovely spaces to relax at anchor without the rolling motion that monohulls have a tendency to do in a swell. During our 15 years of cruising on a monohull, we have often had to leave anchorages that we really were not finished exploring because of a rolly, uncomfortable anchorage. Big rollers or swells coming into an anchorage can make conditions in an anchorage very uncomfortable and unsafe.

We were anchored off Funchal on the island of Madeira in our monohull Royal Salute once, when we were forced to leave our anchorage. The rolling became so bad, we were rolling from gunnel to gunnel. The anchorage became untenable to remain anchored, forcing us to go out to sea in foul weather in the middle of the night. This is an extreme case but believe me, we have left many an idyllic anchorage because of a rolling swell into the anchorage. Catamarans, on the other hand, do not roll from like monohulls have a tendency to do and are far more comfortable at anchor.

5. Anchor Bridal Setup

Catamarans are fitted with a bridle, attached to both bows and down to the anchor chain, resulting in a very stable position at anchor. What we found with our monohull was that because the bow acts as a sail (because of the high freeboard), the boat tended to sail at anchor in high winds. It sailed in one direction until the chain snatched and tacked over and sailed in the other direction, feeling like it might dislodge the anchor altogether. The catamaran on the other hand sits at anchor a lot more stable and doesn’t sail around as much.

6. Ease of Boarding on a Catamaran

Thank goodness we were much younger and more agile during our monohull days. Royal Salute and most monohulls of her generation or older, have high free-boards, making it quite a feat to get onto the boat from the dinghy. It was one of the most challenging things to do because unlike the more modern monohulls that have a scoop at the back, we had to climb up on the side of the boat to get on and off. We, of course rigged steps, etc. but it was always a hassle compared to the ease of getting on and off a catamaran from a dingy or from the water.

7. Shallow Draft Equals Better Anchorages

Catamarans have significantly shallower drafts than monohulls, allowing for safer anchorages closer to shore. Most catamarans in the 40-ft to 50-ft range draw between 3-ft to 4.5-ft, so they can anchor in places that a monohulls can not even consider. In the shallow waters of the Bahamas for example, the catamarans have a big advantage. We often anchor our own catamaran just a few feet away from a beach. It definitely allows one to be able to explore areas where the water is shallow without the fear of running aground.

The shallow draft also allows for emergency repairs in shallow water and even doing the bottom job when the tide goes out as we have done in places like Mtwapa Creek in Kenya, East Africa. The catamaran easily rests on her keels on the sand without help making it a breeze to do the “annual haul out” even in remote locations.

8. Dinghy Davits & Dinghy Size

All catamarans have a set of davits that make it very easy to raise and lower the dingy. Our monohull and most cruising monohulls do not have an efficient or easily accessible set of davits. This makes raising and lowering the dingy an elaborate production. Catamarans on the other hand, has davits systems easily accessible and some even have platforms to rest the dinghy on.

The lack of beam and difficulty of lifting the dinghy also limits the size and type of dingy that one can reasonably carry on a monohull. As we all know, the dingy is your transport to and from shore and diving or fishing spots, so the bigger and faster the dingy, the better off you are. A catamaran can carry both a heavier and bigger dinghy which makes the popular center consul dinghy so much more possible.

9. Interior Space and Comfort on a Catamaran

We sailed 32,000 NM on our 45-ft monohull, happy as clams, not realizing that sailing does not have to be done lying on your ear 24/7 while on passage or sitting knee-to-knee in the cockpit at anchor with your two other guests at the dinner table! One can liken sitting in a monohull cockpit to sitting in an empty Jacuzzi, you are always nice and close to the other folks.

Now that we are on our fourth catamaran, there are a few things that have become more evident to us than the incredible space and comfort of a catamaran, not only at anchor but also underway. The cockpit and living space in general are huge compared to a monohull, making for very comfortable and spacious living conditions. It feels more like you are at home, rather than just on a camping trip.

Knowing that one spends at least 90% of one’s cruising life at anchor, it’s important to have good open living space, which most modern cats nowadays offer. A lot of cats have walk around beds, lots of storage, every modern appliance including washer/dryer, etc. However, one has to fight the urge to fill the space if you want to keep the cat light and fast.

Sailing with guests onboard for extended periods of time, in close quarters can become claustrophobic but on a catamaran people are spread out and separated. With guests sleeping in one hull and the owners in another, catamarans offer much more privacy and separation. Some cats even have privacy doors that will close off the entire hull and has a separate entrance onto the deck, which really separates you from the guests completely.

There is very little heeling on a catamaran, so there is no need for hand grips and safety harnesses inside the boat. There is nothing better (and safer) than being able to walk from the cockpit into the living room (saloon) on one level or one step down at most. In a monohull, when heeling at a severe angle, you would have to claw your way from the companionway steps down to the living area, while fighting to stay upright, significantly tapping your energy.

Unless you hit extreme conditions, everything stays put on a catamaran reducing the anxiety before doing passages of having to stow and secure everything. This very issue makes a lot of cruisers reluctant to weigh anchor and explore more often. It is just too much effort to pack away all your stuff once comfortable in an anchorage!

One thing you will notice is that the stove on catamarans are not gimbaled like it is on monohulls and this should tell the story in itself. The stability and comfort on a catamaran is far superior. Cooking is easy and safer. I often open a nice cold beer, put it down to do something and forget about it only to find a warm beer later in the same place I left it. This is not something that happens on a monohull.

10. Redundancy on a Catamaran

Unlike monohulls, catamarans have a lot of critical redundancies. That of course means two hulls to clean and anti-foul, double the engine maintenance, etc. but having two of the critical equipment like engines for instance, outweighs the downside.

With two engines, if one fails you still have adequate propulsion to go anywhere. If by some fluke the second engine also fails, you have a full set of spares to fix at least one of them. Our friends once hit a sleeping whale off Tanzania, and when it dove, it hit the prop, bending it. They limped into the narrow channel on the one engine but at least they could make it to a safe harbor where we surveyed and repaired their damage.

We often only use one engine when motoring while making passage in order to conserve our fuel. The one engine is totally capable of moving the boat along at a good speed unless you are in heavy seas and you may need more power. Other than that we only use two engines to dock or maneuver the boat in close quarters.

Because there are two engines there are also two independent charging systems via the alternator on each engine. If one alternator goes out, there is still another complete charging system. There are two rudders and if one fails or falls off (as has happened to our friends on a monohull off Columbia, where they almost lost their boat) you have a second rudder that is completely capable of steering the boat by itself indefinitely. That holds true for several things on a catamaran!

11. Maneuverability

The engines are spaced far apart on a catamaran and it makes maneuvering much easier and more precise than monohulls, unless the monohull has a bow thruster. We did not have a bow thruster (not many monohulls do) and had to rely on prop-walk and using prop wash on the rudder. A modern catamaran can do a 360 turn on her own axis. A monohull cannot do this and have a bigger turning circle. However, a monohull under sail is much more maneuverable and certainly will tack a lot faster than a catamaran. The ease in maneuverability under engine on a catamaran in close quarters specifically, is vastly superior comparatively.

12. Rigging

Because of the beam on a catamaran the spinnaker pole has become unnecessary equipment. Hallelujah, I say. That pole on our monohull was a pain the behind and I always hated having to use it. On a catamaran, one can fly an asymmetrical cruising chute or spinnaker, using the bows to tack the clew or run a guy through a block so it is very much simplified, easier and safer.We also sail wing-on-wing with twin headsails when we sail downwind. We use our furling jib and furling Code Zero. It is as easy as one, two, three.

DISADVANTAGES OF A CATAMARAN

1. bridgedeck slamming.

One advantage most monohulls do have when underway is that they don’t slam. Catamarans with a low bridgedeck clearance can experience significant slamming in confused seas sailing upwind. This slamming can be quite disconcerting when you first experience it as we did on a Shuttleworth 44 design, our first ever catamaran experience, 20+ years ago. At times, it felt as though the boat was falling apart. Of course the boat was fine but nevertheless, the stress on the crew from the constant noise and discomfort was significant.

Monohulls don’t have a bridgedeck which means no slamming and are therefore a bit more comfortable than l ow bridgedeck catamarans when beating into severe confused conditions or “washing machine” conditions as we call it. Modern catamarans mostly have better bridgedeck clearance and the slamming is significantly less. However, not all cats have a good clear tunnel under the bridgedeck. Some manufacturers build beds into the bridge deck in order to make more space in the chest of the catamaran where the slamming occurs. These protuberances into the bridgedeck tunnel will likely increase slamming. So be mindful of that when selecting a catamaran. We currently own a Bali 5.4 and the bridgedeck clearance on this boat is more than adequate and the tunnel is clear. We therefor experience very little slamming compared to our Prout 45 that we previously owned (picture of sister ship below) with a much lower bridgedeck.

We Explain Bridgedeck Clearance

In the pictures below, the Bali 5.4 has very good clearance from the water to the bridgedeck and has a nice clean tunnel versus the very low bridgedeck of the Sunreef 50.

2. Sailing Downwind

Monohull spreaders are set at 90 degrees to the mast whereas a catamaran has to have backswept spreaders. The reason is that, on a monohull, there is a backstay and using this, plus the intermediates you can get a nice pre-bend in the mast (the pre-bend is to flatten out the main sail and allow for better performance).

On a catamaran with no back stay, you need to use the back swept spreaders and the diamonds to pre-bend the mast. The reason I point this out is because on a catamaran, if you want to broad reach or run, the mainsail cannot be let out all the way because the backswept spreader tips could punch holes in the fabric.

On a monohull, the spreaders are at 90 degrees so you can let the main and the boom out much further which is, of course, much more effective. This is one of the reasons it is better to broad reach and tack downwind on a catamaran.

Whether a monohull or multihull, sailing dead downwind doesn’t usually make great VMG. Therefor a regular cruising cat, much like a monohull, needs a lot of sail area and has to sail deep downwind if it is to achieve a decent speed made good (VMG). This video demonstrates how we achieve this by sailing wing-on-wing downwind.

It is more difficult to find a dock either as a transient or a permanent slip for a catamaran in general because of the wide beam. But this is changing fast and will soon not be too much of an issue. In the USA dockage is charged by the length of the boat in feet, so there is no disadvantage there but, in some places, (the Mediterranean for example), dockage is charged at length times one and a half because of the additional beam.

Since the catamaran is stable at anchor, we mostly anchor out. We have more privacy, a better breeze and usually a stunning view.We have a nice dinghy with a good outboard engine and is big and comfortable enough to get to shore fast and together with the modern conveniences like the generator, watermaker and washer/dryer, docking becomes a non-issue.

It is definitely more difficult to find a travel lift with enough beam for a catamaran for a haulout, while, for a monohull, there are absolutely no problems anywhere. The wide beam of cats also greatly limits the number of shipyards that can haul them out. Most catamarans over 40-ft must be hauled out with a 50-ton travel lift. This not only increases the cost of the haulout, but greatly limits the choice of the shipyards for repairs and maintenance. With limited choice, prices are high for shipyard services.

Catamarans do tend to have a lot more windage than monohulls. This can be an issue especially when maneuvering in close quarters with a strong wind. But I have found that, provided the engines are powerful enough for the size of catamaran, that twin engines negate this problem. Also, many modern large catamarans now have a bow thruster fitted. It is super easy to dock.

The cost of getting into a catamaran is much higher than that of monohulls. That could put a serious dent in your cruising kitty or require you to put your dream on hold a little longer. Pre-owned monohulls on the other hand are very cheap to buy comparatively, because the supply presently far outweighs the demand.

Catamarans are in high demand and they typically hold their value much better and longer and the trend is now heavily in favor of the catamaran market. When prospective buyers contact us for catamarans under $250,000 the choices are very limited and catamarans under $100,000 is near impossible to buy. In this case, your best bet is to go with a monohull unless you go with much older boats like the Prouts or the less expensive Geminis.

Our Own Catamarans & Monohulls

FYI: Royal Salute , a Bruce Roberts 45 monohull, was the first boat we owned and sailed approx. 30,000NM on. Mythral, a Seafarer 30, was our “toy boat” while we were waiting for our catamaran to be built. Even though this classic little monohull sailed around the world, it didn’t have much in modern conveniences like running water. Siyaya was an Island Spirit 40 catamaran that we sailed from Cape Town to Florida on and then taught live-aboard sailing classes for several years. Zuri I was a Prout 45, a beautifully crafted catamaran but by today’s standards is considered old technology. Our Lagoon 450 SporTop ( Zuri II ) is a fantastic live-aboard catamaran. We lived and taught aboard her for three years but sold her last year and we currently own a Bali 5.4 ( Zuri III or Z3 as we call her now). Read about our various boats .

CONCLUSION: CATAMARAN vs MONOHULL

We were dyed in the wool monohull sailors for 15+ years. We loved the pretty lines of monohulls, the sailing ability and what we believed at the time to be much safer vessels. However, now that we have been avid catamaran enthusiasts, we simply can never go back to monohulls. Catamarans have come of age and with modern technology have overcome most objections that sailors of old had against them. They are well designed and built, are safe, and we simply love that they sail fast and upright. There is not a whole lot to dislike about a catamaran when you live aboard. We have weighed all the pros and cons of catamarans and found that the pros far exceed the cons. We made the change to a catamaran and do not regret it one bit!

We hope that this article will clear things up for all the prospective catamaran owners out there.

4 thoughts on “Catamaran vs. Monohull: We Changed, Should You?”

I read that the engineering on the catamarans were improved over the years. Whats the oldest year would you recommend designwise?

Scott, my apologies for the late reply. We’ve been traveling in Africa. Anyway, catamarans have come a long way and improvements in technology is happening at lightning speed. I reckon that even the older model catamarans are good. It depends on what your needs are. If you want something a little better performance wise, I would go for something no older than 15 years.

After buying a catamaran what is the difference in expense of a catamaran vs a monohull. Many articles state that not only the initial cost of a catamaran is more it the operating cost as well.

Hi Todd, it is more expensive. The annual dockage and haul out as well as maintenance will be more expensive. You obviously have two engines to maintain and various other pieces of equipment to service in both hulls. While there is more equipment there is also more redundancy and of course you have the comfort factor. So, depending on your situation, it’s probably worth it.

Catamaran vs Monohull: The Great Sailboat Debate

16th jun 2023 by john burnham.

Do you love the natural sounds of water sliding past the boat’s hull and a breeze blowing across your rigging and sails while gliding ahead powered only by the force of the wind? If yes, you are well-suited to spending plenty of time on a sailboat, like so many generations of boat people before you.

But do you take your lead from the Egyptians who rigged sails on their boats built of reeds along the Nile River or follow the path of the Polynesians, who used an outrigger for extra stability and sailed from one Pacific island to the next in the earliest catamarans?

The question of which is better for sailing, one hull or two, has been a matter of debate over thousands of years. Today, let’s explore these two basic types of sailboat, and while we may not settle the argument once and for all, hopefully in the process you will begin to discover which option is better for you.

What Are the Differences Between Catamaran and Monohull Boats?

The monohull and the catamaran (often referred to as “cat”) are the two most common categories of sailboats, and of the two, the monohull far outnumbers the catamaran in popularity due to its simplicity and sturdiness. Advocates of the catamaran, however, are typically even more convinced than monohull sailors that their boats are best due to performance potential and overall spaciousness.

What are catamaran-style boats?

Catamarans are easily identified by their two-hull design. Two hulls sit side by side with an interconnecting deck or structural beams across the bap in the middle. Catamarans have been around since Pacific Islanders and other Austronesian people sailed them centuries ago, and they continue to gain popularity in a wide range of designs both as high-performance racing boats and ocean-cruising designs.

Although not part of this debate, a third sailboat type comparable to a catamaran is a trimaran. Trimaran sailboats are constructed similarly to catamarans but have three parallel hulls rather than two. Collectively, catamarans and trimarans are referred to as multihulls, and sailors of both types often refer lightheartedly to monohulls as “monomarans.”

What are monohull-style boats?

Monohull sailboats are the most common boat type because they feature a single hull, typically with a single mast and two sails. Rather than maintaining stability with a second hull creating a wider beam, monohull boats usually carry lead or other heavy ballast in their keel, or are stabilized by human weight as their crews lean out to counter the force of the wind. Monohulls can also be excellent racers and cruisers, depending on their size, volume, sail area, and displacement or weight.

Where Catamarans and Monohulls Excel

Each type of boat has its advantages, depending on what the owner wants in a boat. Here are the main advantages of each type.

Catamaran advantages

• More space . Catamarans have greater beam for a given length, which provides more space for the crew on a daysailer and larger living quarters on cruising designs, which are often laid out with berths in each hull and living quarters across the bridgedeck between hulls.

• Faster hull . If they are light enough, the sleeker shape and reduced wetted surface of two narrow, shallow hulls can produce quicker straight-line sailing speed than a single, deeper and wider hull.

• Comfort and stability . Two hulls provide better initial stability and generally heel less than monohulls, especially in light- or medium-strength winds and waves.

Monohull advantages

• Upwind sailing . When sailing against the wind, monohulls often sail at a closer angle to the wind and arrive more quickly at their destination.

• Easier motion . Heavier monohulls often have a slower, gentler motion in waves than a lighter catamaran.

• Load carrying capability . A monohull’s performance is reduced less than a catamaran’s when the boat is loaded heavily with cargo or crew.

• Righting characteristics . Larger monohulls have weighted keels that provide increased resistance to a capsize when the boat is heeled far over by wind or a wave and if capsized will return the boat to an upright position.

Catamaran vs. Monohull Sailing Speed

There are several reasons why a catamaran is often faster than a monohull boat. These include the fact that most catamaran hulls have less water resistance than monohulls, they are often lighter, and they can be more easily driven by a relatively small sailplan. At similar lengths, a catamaran can be dramatically faster than a monohull under similar sea conditions. However, weight is the enemy of a catamaran’s speed; a heavy or heavily loaded catamaran may be much slower than a lightweight monohull.

Catamaran vs. monohull power

A monohull under auxiliary power may be faster than a catamaran in certain conditions, like powering against a strong wind. In other wind and wave conditions, the catamaran is often faster. Also, with an engines on each hull, the cat is often much more maneuverable in close quarters or at the marina. While it may seem counter-intuitive, turning and controlling the boat is often less challenging than when sailing a monohull boat with the typical single engine. Monohull boats require more finesse when in tight quarters like berthing in a marina.

Catamaran vs. Monohull Efficiency

A sleek monohull may sail against the wind super efficiently, pointing close to the wind and making an excellent speed. However, the power-to-weight ratio of the catamaran allows it to make good use of whatever wind it has. Some fast, light catamarans can travel at speeds equal to or faster than the wind, something very few monohulls can achieve. When the wave action increases and you start sailing into the wind, the catamaran may lose its advantage, and in strong winds, the greater windage of the wide catamaran may have a pronounced slow-down effect compared to the sleeker monohull.

Catamaran vs. Monohull Stability

Despite not having a weighted keel, a catamaran design is able to avoid heeling over in strong winds or bad weather due to its greater width or beam. As a result, the multihull also tends to be more stable at anchor and any time in calmer seas. However, if the winds are strong and the waves are large, a monohull, with its keel weight and ability to sail against the wind while controlling the sails, is sometimes the steadier of the two types. While a monohull with weighted keel can be knocked down by strong gusts of wind, it will only capsize in extremely large waves. Likewise, a cruising catamaran can only capsize in large ocean waves, unless it is a fast, lightweight catamaran, that can more easily tip over in gusty winds and waves.

Catamaran vs. Monohull Safety

Power catamarans and power monohulls are relatively comparable in terms of safety. But depending on the size of the mast and sails, the weight of the boat, and the wind and wave conditions experienced, many sailors believe that a monohull configuration is safer than a catamaran for a sailboat. That’s mainly because while a monohull will initially heel over further in a strong gust of wind, the weight of its keel provides increasing stability as described above and if completely capsized, the keel typically helps the boat self rescue.

It should be clarified that many sailing catamaran designs are conservatively configured and difficult to capsize except in extreme ocean wave conditions—and the same can be said for larger power catamarans.

In terms of ultimate safety in the event of a capsize, however, the catamaran is considered safer because even should it turn once upside down, even if damaged, the catamaran with its two hulls and minimal ballast typically remains buoyant and provides a safer configuration in which to await rescue. By contrast, if a monohull’s hatches and port windows suffer damage in a knockdown, the boat can more quickly take on water and, weighed down by its keel or other ballast, be more difficult to keep afloat in extreme conditions.

Monohull vs. Catamaran Maintenance

Depending on size, age, and type of hull construction, maintenance costs will vary, but when comparing two fiberglass sailboats of similar length, the catamaran typically costs more to maintain. That’s because there are two hulls to care for, two engines, connecting structures that align the two hulls, and an overall larger boat due to the catamaran’s greater beam. Hauling and launching a catamaran can be more expensive at many boatyards, as well.

However, smaller catamarans of about 20 feet in length or less are often more comparable and sometimes cheaper to maintain than a similar length monohull. That’s because cats are often lighter and suitable for keeping on a trailer rather than in a slip or on a mooring.

Catamaran vs. Monohull Cost

Compared to similar length monohulls, a catamaran will likely cost more than a monohull boat. That’s mainly because when you purchase a 40-foot catamaran, you are buying two hulls and two engines, but you are also buying a bigger boat that typically has much more volume. In the case of a 40-footer, you end up with a boat that has a large saloon and three or four private cabins, whereas in the monohull, the saloon is smaller and you’ll have three smaller sleeping cabins. Annual maintenance will also be greater, as described above.

Among smaller catamarans and monohulls, pricing will vary, and a lightweight beach cat may be less expensive than a heavier monohull keelboat of similar length.

Catamaran vs. Monohull, Pros and Cons

Depending on a variety of factors, there are plenty of catamaran and monohull pros and cons. These are some to keep in mind when comparing the two boat types.

Catamaran pros

• Comfort . On a cruising designed catamaran, two hulls with a wide beam create a stable and comfortable living environment with open spaces and plenty of standing room.

• Speed . Smaller, lighter catamarans are speed champions, especially in a moderate wind and modest waves. Cruising cats are often fast when sailing at reaching angles.

• Maneuverability . When equipped with two engines, a catamaran is highly maneuverable under power.

Monohull pros

• Upwind sailing . Although catamarans are often faster when sailing in a straight line, monohulls typically perform better against the wind.

• Self-righting . Except for unballasted monohulls that rely on crew weight for stability, the ballasted keel of a monohull prevents capsizing in most circumstances and the keel makes the boat self-righting.

• Maneuvering under sail . Monohulls turn more easily due to their shape, maneuvering in close quarters or tacking when sailing against the wind.

Catamaran cons

• Lack of feel when steering . Except in lighter, more performance-oriented catamarans, the broad platform with two rudders and two hulls sometimes isolates the sailor and provides little feedback through the helm when under sail.

• Sailing against the wind . Upwind sailing is generally not a catamaran’s best point of sail, but its straight-line speed can be such that it may arrive quickly at its destination, even though you will have traveled much farther than in a monohull.

• Pricing . Catamarans are typically more expensive than monohull boats due to their two hulls and other required build components and complexity.

• Not self-righting . Thanks to its wide beam and two-hull design, a catamaran is more difficult to flip, but it is not designed to right itself except for small beach cats where the crew can use their weight to re-right the boat.

Monohull cons

• Weight . Most monohulls have thousands of pounds of weight in the keel for ballast that is vital to its stability but can degrade performance.

• Wave motions . Monohull boats are much more susceptible to rolling wave motions.

• Cabin . With the monohull cruising design, you'll typically find a darker interior with smaller port windows and fewer space options.

• Heeling effect . Monohulls will heel over in a moderate wind, which is normal but often uncomfortable for newer sailors.

Catamaran Or Monohull? 27 Important Facts (Explained)

Catamarans and monohull boats are two very different kinds of vessels. Each craft offers distinct advantages and disadvantages that you’ll want to consider before choosing between the two.

In this post, we’ll go over some of the important things to consider when choosing between catamarans and monohull boats:

Table of Contents

Cost & Availability

Both catamarans and monohull boats come in small recreational sailing versions, larger motorboat versions, and larger sailing models. In all cases, the catamarans will cost more and will be harder to find.

The reason catamarans are harder to find because there are not as many of them, and they’re mostly made overseas.

Also, there aren’t as many catamaran manufacturers, so sailors have fewer options when buying them.

On top of this, catamarans have only recently become popular in the United States and other areas of the developed world. This means the used market for boats doesn’t have as many catamarans on it. You might find that you have fewer options when making a used catamaran purchase, which could bring costs up to a premium.

Two Times The Fun with Catamarans

Another reason that catamarans are more expensive than monohulls is the fact that catamaran buyers have to purchase two hulls, two engines, and two of all of the components that help make an engine work.

Traditional sailboats and large powerboats with one engine don’t have this cost issue.

On top of this, a catamaran is much wider than a monohull, and thus you have more space to build and equip.

On the other hand, once you’ve purchased the boat, you do get to enjoy the benefits of having two of everything. We’ll talk about the advantages of this further down in this post.

Maintenance Cost Makes A Difference

The maintenance on a catamaran is also more expensive than the maintenance on a monohull boat. This goes back to the fact that there is twice as much of everything to maintain.

Catamaran owners will need to do preventative maintenance on two different engines, and they’ll have two hulls and a large deck area to clean and maintain as well. If they’re getting the bottom of the boat treated, they’ll have to do this twice (once for each hull).

Even the interior components can usually be found twice.

Each cabin will usually have a head in it, so you’ll have at least two toilets and sinks to maintain, which obviously has its plusses and minuses.

One positive aspect of this is that catamaran owners do have the option of deferring some of their maintenance. For example, if one head is no longer functioning properly, you always have the second one that you can use.

It also adds a bit of safety as well.

This is because while the catamaran does have two engines to maintain, the owner does have power even if one of the engines happens to go down.

Some catamaran owners also like to point out that maintenance may not have to be done as frequently. This is because the engines don’t have to work quite as hard, and other items like additional bathrooms and sinks might only be used half as much.

How Much Space Do You Need?

A catamaran has more space than a monohull. This is because the boat is wider, and it has a much larger deck area. It also has twice as many hulls, so you have more overall space between the two of them.

The additional space is great for people looking to throw parties on their boats.

Most boat owners would agree that the catamaran is usually the party boat of choice at the docks.

Even if you aren’t into throwing parties, the extra space can still be nice for relaxing on the deck or getting a suntan. The wide-open space also makes it easy to use the boat as a fishing platform.

Additionally, you have more space for stuff like surfboards, rafts, and other items that can easily clutter up the deck of a monohull. Even fishing can be easier from a catamaran as the deck provides plenty of space between different anglers.

Catamaran owners also have additional space for carrying fresh water and adding generators and solar panels.

Interior space is generally more plentiful on a catamaran, and luxury catamarans have an easier time fitting large items like washers and dryers inside of them. You can have these on larger monohulls as well, but it will be harder to make them fit than it is in a catamaran.

On the other hand, all of the additional space means the catamaran owner has more space to maintain and clean. Also, all of the additional items that can be brought onto the boat will make it heavier. A heavier boat will use more fuel, and it will travel more slowly.

Living Quarters Vary Between The Two

The living quarters on a catamaran are much different than they are on a monohull. Most people would agree that the berths in a monohull are much more spacious than in a catamaran.

A monohull offers people the opportunity to have a large bed with space on either side to walk around it. This is great for couples who want to get out of bed without waking up their partner.

Catamarans, on the other hand, have the advantage of being able to offer large above-deck salon areas. The galleys, the dining areas, and the living areas can all be above-deck, while the two hulls can provide heads and berths.

Some boat owners say that living in a monohull is akin to living in a basement apartment . Other boat owners prefer the monohull because it brings them closer to the water and gives them the feeling of being at sea.

Privacy Can Be Prioritized On Catamarans

A catamaran offers up many different living areas that people can take advantage of. For example, each hull will typically have its own bathroom and bedroom.

This gives each sleeping area complete privacy from the other.

The living quarters are usually up on the deck, so early risers can wake up and move to these quarters without waking up the others.

The same holds for night owls. A night owl can stay up late without bothering the people who want to retire to their beds earlier.

With two hulls, large catamaran owners can hire a crew and give them their own hull to live in so that there is separation between the cruisers and the crew. This is a wonderful advantage for honeymooners looking to have their own space.

The downside to all of this, of course, is that sometimes a family may not want the additional privacy. For example, a family with small children might not want their children in a different hull than they are.

Additionally, the extra privacy can make it hard for people on the boat to communicate. This could become a big problem in the event of an emergency.

For this reason, it is often recommended that each hull have a radio in it so that the occupants can quickly communicate with each other. Remember, even in inland areas, cell phone reception may not be very good inside the boat hulls.

Recreation In a Monohull vs. a Catamaran

Most sailors agree that sailing a monohull boat is much more exhilarating than sailing a catamaran. Traditional sailboats heel, and sailors get instant feedback while they’re sailing. For the most part, catamarans stay stable, and you don’t get the same feeling with the movement of the wind and the water.

When it comes to monohull powerboats, you have the advantage of being able to pull water skiers, kneeboarders, and tubers with ease, as long as the boat has the power and a planing hull. A power catamaran usually doesn’t have the speed or maneuverability to pull off these recreational opportunities because they are displacement hull designs.

Catamarans excel in more leisurely recreational activities. A catamaran makes a great party deck as well as a great cruising deck. Catamaran owners can comfortably walk around a catamaran without having to worry that the boat might knock them over the next time it decides to heel. This allows boaters to sit and talk with one another comfortably.

A catamaran can also be used as a beaching vessel. This makes it a great platform for people looking to go swimming or fishing around sand bars and other shallow water areas. It also makes it a great boat for sailors looking to sail a larger boat on a river or lake known for having shallow areas.

Swimming and Diving

Swimming and diving off of a catamaran are usually much easier than doing the same from a monohull. The wide stance of the two hulls offers boat designers the option to put in staircases at the back of both hulls.

In between these staircases, some boats will have an additional diving platform and/or a dedicated frame for pieces of equipment and dinghy storage. This makes catamarans great for swimmers, snorkelers, and divers.

On the other hand, modern monohull sailboats can also have good transom stairs for easy access to the dinghy and swimming. Both types of boats can easily travel far out to sea, giving boaters the option of diving in areas that can’t be accessed from beaches and developed areas.

Boat Draft In Shallow Waters

For the uninitiated, the boat’s draft refers to how deep the boat’s hull sits within the water.

A monohull typically sits deep within the water, while a catamaran sits much higher on the water. This is why we stated that a catamaran is good for shallow waters.

The advantage of having a boat that can go into shallow waters isn’t restricted to just recreational activities like swimming and fishing. A boat that can go into shallow water is safer to operate in areas where a boat with a deeper draft might become damaged.

Additionally, a catamaran has more stability on calm waters. This helps make a catamaran more comfortable to relax or sleep on while at anchor or the dock.

The deeper draft of a monohull boat has its advantages as well. A deeper draft provides more stability in rough waters and allows a boat to go further into the sea.

For this reason, many coastal cruisers will prefer catamarans, while many ocean voyagers will prefer monohull boats. In fact, some areas of the Caribbean and the Florida Keys can be off-limits to boats with deep drafts as it simply isn’t safe for the boat to navigate these waters.

This isn’t to say that you can’t navigate these waters in a monohull boat, but you will have to be cautious depending on how deep your monohull’s boat draft is. You wouldn’t have this issue in a catamaran.

Stability On The Sea

A catamaran offers a lot more stability in shallow waters, in calm waters, at the dock, and anchorage. This makes the boat great for cruising and for relaxing in port.

A monohull offers a lot more stability in rough waters.

This makes this boat great for heading out to sea and for navigating vast distances.

Safety Issues To Consider

Both catamarans and monohulls can be built to navigate the waters they were made for safely. This will be determined more by the boat’s category designation rather than the type of boat.

However, each boat deals with unsafe situations in different ways. For instance, a monohull boat is likely to right itself if it is capsized.

This means that even in rough seas, you’re unlikely to find yourself permanently capsized.

The downside to this is that should you become completely swamped from a capsize in a monohull boat, you are much more likely to sink. In fact, if there is a hull breach on a monohull boat, your boat could sink.

Catamarans are said to be unsinkable. This isn’t completely true, but it is very unlikely that a catamaran will sink. Even if a hull is breached, you still have a second hull to keep the catamaran afloat.

However, a catamaran can’t right itself. If you capsize your catamaran, it will stay capsized.

One other safety concern to consider is that a monohull sailboat will heel while a catamaran will not. This increases the chances that someone could fall off the boat or onto the deck in a monohull boat.

Catamarans Are Faster Than Monohull Boats

A catamaran is faster than the average monohull boat.

This is because they face less water resistance, and their narrow hulls don’t have to deal with their own bow waves as a monohull does.

Of course, catamarans aren’t always faster. Old cruising catamarans may not go faster than 8 knots, and modern monohulls can exceed 10 knots.

Monohull boats tend to sail downwind and in choppy seas better than catamarans. This gives them a speed advantage during ocean voyages.

We have a separate post with complete average speeds per type of catemaran . It’s a must read if you are at all concerned about speed!

Fuel Consumption Considerations

Catamarans have two engines to burn fuel, which can drive up fuel costs.

However, a catamaran is lighter on the water, so it usually takes less energy to move a catamaran. This means you’ll end up using less fuel in a catamaran than you would in a monohull.

On top of this, catamarans can decide to use just one engine in low wind areas. This further decreases the amount of fuel that a catamaran consumes.

These rules only apply to calm waters.

A monohull navigates waters with high waves and strong winds much more efficiently than a catamaran. In this case, you’ll use less fuel in a monohull than you would in a catamaran.

Sailing Differences To Notice

Sailing a monohull boat can be exhilarating. These boats can glide through choppy waters, and you get to feel the motion of the boat as the sea rushes by the cockpit and the wind causes you to heel.

This type of sailing also provides instant feedback as you’ll know what you need to do with the sails as you’ll feel what is going on through the boat’s motion.

Sailors all over the world have been using monohull sailboats for years, and you’ll find plenty of outlets for recreational sailing with a monohull sailboat.

Sailing catamarans do not heel like a monohull sailboat.

These boats, therefore, do not provide the sailor with instant feedback. Also, if you incorrectly sail a catamaran, you do risk capsizing the boat more easily.

Training Can Be Quite Hard

Sailing a catamaran and sailing a monohull boat are two different experiences. People looking to sail either should probably get professional training.

Obtaining this training will always be easier with a monohull boat.

This is because monohulls are more popular, so you’ll have more instructors available to you.

Do You (Or Your Friends) Get Seasick?

People who are prone to getting seasick easily might want to consider a catamaran. A catamaran provides much more stability in calm waters, and you get a lot less movement.

On the other hand, people who are not prone to getting seasick might prefer a monohull in choppy waters.

This is because a monohull will deal with deep and choppy waters with high waves much better than a catamaran will.

As a result, a catamarans movement can seem extreme under these types of conditions. People who have never gotten seasick before can end up sick under these conditions.

Here’s a separate article we wrote with everything you should know about seasickness on Catamarans . There are some things you can do and some things you should know!

Docking Is (Usually) Easier With A Monohull Boat

Docking a catamaran can be a difficult endeavor.

This is because catamarans are often too wide to be docked within the slips located in central areas of a marina.

Because of this, they need to be docked at the end of the dock. This leaves them with fewer spots to dock. It also makes docking more expensive.

Catamaran owners traveling through areas that are unlikely to have many catamarans in them may find it difficult to find a dock at all. This is true in areas of the northern Atlantic where monohulls are much more popular than catamarans.

Storage Issues To Consider

Even storing a catamaran can be more difficult. This is because storage facilities often do not have the equipment to get a catamaran out of the water.

The wide width of these boats requires special lifts, and not all boat marinas will have them.

Storage facilities that do get the catamaran out of the water will often charge more money for it. They’ll charge additional fees for taking the catamaran out of the water, and they’ll charge additional fees for the actual storage of the boat as well.

Redundancy And Backup Equipment

We touched upon this earlier, but it is worth repeating that catamarans have many redundancy built into them. This can be a big advantage when it comes to safety.

For example, if one rudder becomes inoperable, the boat can still be steered with the other one. If one engine becomes inoperable, the boat can still be driven with the other one.

In extreme cases, a hull could become damaged, and you could still stay afloat because the other hull will keep the boat safely above water. These safety advantages can save lives and keep people from becoming stranded out at sea.

The primary downside is the maintenance issue that we mentioned earlier. All of these redundant components will need to be maintained. As a result, maintenance costs will be close to twice as expensive in a catamaran.

Cooking Is Easier On Catamarans

Cooking on a catamaran is usually easier than it is on a monohull. The main reason for this is that a catamaran doesn’t heel like a monohull, so you don’t have to worry as much about things falling over.

This not only makes cooking easier, but it makes cooking safer as well.

Additionally, catamaran galleys tend to have more space in them to move around. Also, they are often up on the deck, so you don’t have to climb in and out of the hull with your dinner in hand.

Dinghy Storage

Monohulls and catamarans can both hold dinghies. The larger the boat, the larger the dinghy can be.

However, catamarans have a wide area at the rear of the boat that is perfect for holding dinghies.

This makes getting in and out of the dinghy easier. Also, people can often have larger dinghies on their catamarans because the boat’s stern is so accommodating.

Power Generation Is Easy On A Catamaran

A catamaran has a lot of space for solar panels and wind turbines. Rigid panels can be placed in areas that won’t be walked on, like overtop of the bimini, and flexible panels can be placed in areas where the panels might end up getting stepped on.

The width of a catamaran even gives them more opportunities to put hydro generators into the water.

This means catamarans can generate more power than the average monohull boat can generate.

On the other hand, a monohull usually has less powered items to worry about. Monohulls need less power to operate at full capacity, so you may not need all of the additional space for generating power.

Ventilation Issues To Think About

Some people feel that monohull boats don’t offer enough ventilation. This is especially true in warmer areas of the world.

Catamarans also lack ventilation within their hulls, but fortunately for them, much of the living space is located up on deck. This gives catamarans an edge when it comes to cruising in warm weather.

On the other hand, monohull owners aren’t exposed to the cold winds that you might find up on deck in harsher climates.

This lack of airflow may actually be of benefit in this instance.

Some people find monohulls to be better looking than catamarans and vice versa.

This all comes down to personal preference, so you’ll have to decide for yourself which type of boat has the advantage in this case.

Some people think catamarans are the most elegant thing in the world while others prefer monohull boats as they look more classic.

Resale Value Is An Important Factor

If you read our extensive guide to boat depreciation per boat type , you know that no matter what boat you buy, it will always go down in value. This is just a sad fact of boat ownership that people need to consider before buying a boat.

Many factors go into how much you’ll be able to get for your boat when you resell it. These factors are the condition of the boat, the age of the boat, and the economy in general. For example, people are less likely to want to buy boats during a recession. This is especially true when it comes to smaller boats.

However, one additional factor that catamaran owners need to consider when thinking about resale value is the value of the dollar.

People from the United States don’t have many American catamarans to choose from and will usually need to buy these overseas.

This means that a catamaran will be less expensive to buy when the dollar is strong compared to the Euro and more expensive to buy when the dollar is weaker in comparison. This will affect the used market as well because higher values on new catamarans can help to bring up the value on the used market.

With a monohull boat, you may not have to consider situations like this as there are makers of monohull boats all over the world.

Don’t Let The Length Trick You!

One thought to keep in mind when comparing monohull boats and catamarans is that their different shapes account for different space advantages.

For example, a 40-foot long catamaran will have much more cubic space than a 40-foot long monohull.

Because of this, when comparing boats, you should look at the cubic space rather than the length. In this case, you may be comparing a 48-foot long monohull with a 40-foot long catamaran.

When you compare the two types of boats in this manner, the price differences aren’t quite as large, and the comparison is fairer. It also may make the operating and maintenance costs more similar.

This is an important distinction to make because the length of the boats can trick you!

Consider Trying Both (Before Buying)

Boats can be an expensive purchase, so it makes sense to try them out before you decide to make your purchase.

Rent each type of boat and use it on the types of waters that you intend to cruise on the most.

Try the boat out in different weather conditions as well, and don’t be afraid to do multiple rentals before you make your final choice. The time and money invested into making sure you get the boat you really want will be more than worth it in the end.

Catamaran vs Monohull: Pros, Cons & Main Differences

By: B.J. Porter Editor

The choice of catamaran vs monohull ultimately comes down to preference. What’s critical for one buyer may mean little to another. If your partner refuses to set foot on a boat which heels, that’s a deal-breaker for a monohull. But if you’re passionate about classic looks and styling, your quest for beauty may override other considerations and rule out catamarans.

We can’t tell you whether a catamaran or a monohull is right for you. But we can help you with the pros and cons of each for your search.

The Strengths and Pros

No matter your choice of monohull or catamaran, there are safe, comfortable, and excellent sailing boats of both types. Neither has an exclusive lock on any strength, and both sail safely and comfortably. But there’s a different emphasis on how they do it. No matter what you are trying to do – sail fast, cruise the world, or just host a crowd at the dock, there are monohulls and catamarans that can work for any requirement.

Catamaran advantages

Space and comfort: Two hulls and a wide beam make a very stable platform with lots of volume in the saloon and cockpit. Most living space is above the waterline, with wonderful light and airflow. Cabins in the hulls offer better privacy and isolation, usually with standing headroom.

Straight line speed: Most catamarans are faster in straight-line sailing speed (1) that similar sized or even longer monohulls. Without a lead keel, they’re lighter, so more driving force from the sails converts to speed, and narrower hull forms may have less drag than wide hulls with deep keels. Some heavier cruising catamarans may not be faster, especially if they keep rig size small for ease of handling.

Stability : The beam of two hulls with a bridge deck leads to much higher stability and resistance to roll (2). Waves in an anchorage that induce violent roll in a monohull may make a catamaran bounce or bob. Under sail, catamarans do not heel appreciably even when powered up.

Twin engines. : With one engine in forward and balanced in reverse, most catamarans can spin in a circle in place and make sharp adjustments to the boat’s direction. If you have an engine failure, you also have a second engine, giving a safety edge when you can’t sail.

Monohull advantages

Upwind sailing performance: While catamarans have the edge at straight-line speed, monohulls sail closer to the wind. When you’re racing or you have to sail upwind to get to the next island, this can get you there faster.

Sailing feel and responsiveness : The “feel” of sailing a monohull is much better. With a single hull, you’ll feel wind pressure and trim adjustments immediately for a more responsive helm and a better ability to sail to the wind.

Maneuvering under sail: Monohulls are quite nimble tacking and turning under sail, and there’s less risk of slow or missed tacks.

Righting Moment: The primary offshore safety argument for monohulls is their ability to right when capsized. The heavy keel keeps the boat deck up when sailing, and most monohulls will come back upright even after a complete capsize.

Cargo and Loading: A higher displacement boat with thousands of pounds of lead hung from the bottom isn’t going to be as affected by loading as a relatively light multihull.

Aesthetics: This is subjective, as many catamaran enthusiasts love how they look. Classic sailboat styling, with swept sleek looks, springy sheer lines, and all the “right” proportions are more common on monohulls.

Weaknesses and Cons

Like strengths, weaknesses are relative; just because one class has a strength doesn’t mean the other doesn’t. There are spacious monohulls and beautiful catamarans, just like there are cramped catamarans and unattractive monohulls. The differences have to be highlighted relative to each other, and the weaknesses of one are most apparent compared to the strengths of the other.

Catamaran Cons

Upwind performance: Cats don’t sail as close to the wind, but they make up for it by sailing faster off the wind. You’ll sail a less direct course upwind. Even if you get in at the same time, you’ll have to sail farther.

Less responsive sailing: Two hulls with two rudders and a very broad platform reduce the helm feel when sailing, cutting responsiveness sailing in shifting wind and wave conditions. It also makes tacking slower.

No-flip zone: It is very difficult, but not impossible, to flip a large catamaran (3). But if a catamaran capsizes, it will not flip back over by itself.

Large in marina/close quarters: You have two problems in marinas. Beamy cats are tough to maneuver in tight spaces because they’re big and visibility is tough over the hulls. And many marinas charge extra because the wide beam extends into the next slip. The good news is that twin engines make tight maneuvering easier.

Price point: Catamarans are more difficult to build and need more materials. This is directly reflected in the cost of the boats.

Monohull Cons

They are heavier: Every large monohull needs a keel for stability (4). They can not sail or stay upright without thousands of pounds of ballast, and this makes them heavier and slows them down. Tiny monohulls can use a centerboard or daggerboard for stability, but most boats big enough to sleep on need ballast.

Darker interiors : Most monohull living space is lower in the boat, where you can’t put enormous windows for light and circulation. It’s very hard to get space as bright and airy as catamaran saloons.

Less living space: With one hull and no bridge deck saloon, most monohulls feel cramped compared to spacious catamarans.

More prone to rolling motions : Only one hull makes monohulls susceptible to rolling in waves, and the movement can be quite uncomfortable.

Heeling: Tipping is just part of sailing monohulls upwind and is unavoidable. It can be reduced on some other points of sail, but not eliminated. Many people, especially non-sailors and new sailors, find this movement uncomfortable or distressing.

Catamaran Sailing – What’s the Difference?

By: American Sailing Sailboats

What is a Catamaran?

A traditional sailboat is a monohull–in other words, it has only one hull centered around a heavy keel. A catamaran is balanced on two hulls, with the sails in the middle. It’s as simple as that. Depending on the size of the boat, the space separating the two hulls might be filled by a cockpit, a main cabin, and usually some netting (which can be a great place for relaxing in the sun). Why are Catamarans Popular?

In response to their rise in popularity, ASA developed 114: Cruising Catamaran . This course is ideal for people who already have monohull cruising experience and want to translate that over to the catamaran. You’ll learn all the advantages and disadvantages of multihull sailing so that you’ll always be making an informed decision when considering which boat to charter or buy. You’ll also get the practical sailing skills you need to be confident and have a great time on your cat. Contact an ASA school near you to see if they offer ASA 114: Cruising Catamaran.

Catamarans vs Monohulls: Which is Better a Better Sailboat For You?

The question of whether to choose a monohull vessel or a catamaran is an eternal dispute between boat lovers. These arguments are usually based on one’s preferences and philosophy. In fact, the popularity of catamarans has grown significantly since their design facilitates many aspects of sailing. But, both mono-hulls and multi-hulls have their advantages and disadvantages. So, in this article, I’m going to list some details about both cats and monohulls so as to help you understand which one is better for you. Remember it all depends on what sort of experience you are looking for. Keep reading!

What is a Monohull?

In general, boats float due to the fact that they displace more water than they weigh. The hull is in “displacement mode” while a boat is stationary or moving slowly. That is, all of the upward forces that keep it afloat come from flotation, which is achieved by displacing water. With certain hulls, increasing the boat’s speed beyond a particular point causes the hull to lift up and skim along on top of the water. This is referred to as “planning.” Monohulls can be divided into two types; displacement and planing hulls.

Some hulls are only capable of moving at displacement speeds . This style of boat has generally slow speed, but it is incredibly efficient to operate. While moving, most have a smooth motion , though rolling (side-to-side movement) might be an issue. On the other hand, while on the sea, achieving fast speeds requires a hull that can readily transition onto a plane. Flat bottom surfaces from amidships aft, or from the middle to the back of the bottom, and a flat transom, or the back of the hull, are the main characteristics of a planing hull. Keep in mind that at a sharp angle, the transom must contact the bottom.

What is a Catamaran?

Nowadays, catamarans are becoming more and more popular. They’re particularly appealing to fishermen since they combine high-speed performance and a smooth rough-water ride with a solid angling platform. Catamarans have two primary disadvantages . Firstly, they require twin engines. Also, larger catamarans may be too broad to fit into standard marina docks. Another disadvantage is that there is less usable interior space than on a monohull of comparable length.

The two hulls of a catamaran are known as amas. These days, the popular phrase is “sponson,” but ama is still acceptable. Note that in comparison to its entire length, each ama is quite short. The narrow amas of a catamaran travel quickly through the water with little power. This allows for fast speeds even when the amas aren’t actively planning.

Trimarans on the other hand have three separate hulls. Sailboat designers have successfully employed this design to provide a large central hull for cabins. But, also for two outrigger amas for stability. The trimaran concept hasn’t been used much in powerboats, despite the fact that several “cathedral” hulls are related. Instead of three independent hulls, a cathedral design squishes them together to the point that they often share a similar planing surface near the transom.

Monohull or Catamaran? Let’s Take a Look at Their Pros and Cons

Catamarans are unsinkable because they are incredibly stable and have natural buoyancy. Yes, they can capsize in a major accident. But, being rescued while floating on the water’s surface is preferable to plunging to the bottom in a monohull. Furthermore, moving around on a flat deck is far safer than on an angled deck.

Classicists have long claimed that catamarans are not as safe as their keelboat counterparts. However, this remark is now regarded as archaic. Since it dates from the mid-nineteenth century when the majority of catamarans were made by amateurs. They could readily tip over even in calm weather, especially if one of their bodies became leakproof owing to damage. Sinking is extremely difficult, if not impossible, for a well-built modern catamaran. Modern structures are designed using computer simulations of various water conditions. Bear in mind that the maximum potential safe sail area is available to cruisers and charter possibilities in particular.

Monohulls , particularly sailboats, offer significantly stronger “self-righting” capabilities in the event of a worst-case knockdown situation. In a catamaran, once you’re upside down, you’re stuck there…And, who wants to be upside down in the middle of the ocean? Returning to an upright position gives you complete access to onboard safety equipment. This includes a liferaft, dinghy, flotation devices, EPIRBs, and strobe lights, which can save you if the boat sinks.

Generally, a catamaran’s high speed allows it to avoid adverse weather . While catamarans do not point as high into the wind as monohulls they are around 20% faster . Or, if they do, they create more leeway or slide sideways. This means that even if you sail upwind at a slightly broader angle to the wind than a monohull and cover a more distance, you will arrive at your destination sooner than a monohull.

A modern performance catamaran with daggerboards and strong sails may point as high as a monohull of comparable size. It will point similar to a comparable monohull but will sail far faster. This allows it to reach an upwind position far sooner than a monohull. However, it’s worth noting that the majority of production cats on the market are underpowered and have standard smaller sails. Many of these designs perform poorly in light breezes. Unless they’re equipped with larger headsails, a Code Zero, and a square-top mainsail.

While cats are more comfortable and safer in rough weather, we must admit that if the weather gets extremely terrible (60 knots of wind or more), it’s better to be on a monohull for survival reasons. For serious offshore single-handed sailing, I believe a monohull is superior since it is easier to hove-to in it. Bear in mind that when you’re in a cat during severe storms you won’t feel any danger, but it demands some nifty seamanship. And, keep in mind that even though a monohull can capsize in bad weather or even roll in a storm, they usually right themselves. A catamaran , on the other hand, is incapable of self-righting . However, the cat will usually stay afloat, providing a safe haven to wait out until aid arrives. Modern catamarans, on the other hand, are extremely difficult to capsize.

That being said, most catamarans can travel 200 to 250 miles per day, and with contemporary technology allowing one to control weather, it’s difficult not to deal with bad weather. In many circumstances, a faster boat is a safer boat because it can outrun heavy weather. A catamaran can avoid the worst weather and, at worst, put itself in the best position to avoid the brunt of a storm if there’s good weather routing information.

So, to sum up, cruising catamarans are quicker than monohulls, and sailing catamarans, depending on their angle, can sail at half the speed of the wind. It’s great to be on a boat that can swiftly attain high speeds and get you to your destination safely and on time. However, catamarans are faster because of their lower surface area , but their prices are generally higher than those of monohulls. Instead of fighting the elements, monohull designs operate in harmony with them . In addition, keep in mind that when sailing upwind, sailing catamarans are inefficient and tack slowly.

Fuel Consumption

Do you want to save money on gas? Then, in most cases, catamarans have less fuel consumption than monohull boats. Catamarans save a lot of gasoline since they have a less wetted surface area on their hulls. They can propel the boat with just one engine in weak winds. Also in flat water, and if the engines have the same number and horsepower. However, in heavier weather , where the higher efficiency of a monohull design provides less resistance , this is not the case.

Generally, catamarans have two fuel-burning engines, which can raise fuel expenses . However, because a catamaran is lighter on the water, it requires less energy to move. In a catamaran, you’ll use less fuel than you would in a monohull. Furthermore, in low-wind areas, catamarans might choose to use only one engine. This reduces the amount of fuel consumed by a catamaran even more . But, only calm waters are subject to these laws. A monohull is far more efficient than a catamaran in navigating waters with heavy waves and heavy winds. A monohull will consume less fuel than a catamaran in this situation.

The best feature of catamarans is that all of the rooms are on the same level. The four-cabin arrangement is common with sailing cats and is popular among charter companies. Owner versions usually feature three staterooms, with one hull serving as a big cabin for entertaining. Most catamarans have a big central living room with not one, but two narrow staircases leading down into the hulls—one on each side. It’s a little like living in a tube in the hulls. They’re too thin to accommodate walkaround double/queen berths like those found in monohulls. But, in case of an emergency, it would be impossible to communicate with someone in the opposite hull.

Obviously, a monohull has less space than a catamaran. This is due to the fact that a cat is broader and has a larger deck surface. It also has twice as many hulls as the other, giving you greater total space between them. People who want to host parties on their boats will appreciate the extra space. The catamaran is usually the party boat of choice at the docks, according to most boat owners. Even if you don’t like to host parties, the extra room might be useful for lounging on the balcony or tanning. The boat’s large open space also makes it simple to utilize as a fishing platform.

You also have more room for equipment like surfboards, rafts, and other equipment that can easily clutter a monohull’s deck. Even fishing from a catamaran can be easier because the deck allows for plenty of space between anglers. Owners of catamarans also have more room for carrying fresh water and installing generators and solar panels. A catamaran’s interior room is often larger, and in luxury catamarans, it’s easier to install heavy appliances like washers and dryers inside. These can be fitted to larger monohulls as well, though it will be more difficult than on a catamaran.

All of the extra space, on the other hand, means the catamaran owner has more room to maintain and clean. Furthermore, all of the other stuff that can be brought into the boat will add to its weight . And, as well all know, a heavier boat will consume more fuel and move at a slower speed.

Maneuverability

With their twin motors, catamarans are incredibly agile . On a catamaran, the engines are widely apart, making navigating more easier and more precise than on a monohull, unless the monohull incorporates a bow thruster. Most of the time, a bow thruster isn’t required because the engines are around 20 feet apart. When there’s no bow thruster (as do few monohulls) you have to rely on prop-walk and prop wash on the rudder. On her own axis, a contemporary catamaran can turn 360 degrees. A monohull would be unable to accomplish this while it has a larger turning circle.

A monohull under sail, on the other hand, is far more maneuverable and will tack much faster than a catamaran. But, the ease of movement under motor on a catamaran, especially in close quarters, is substantially superior. They also feature shallow drafts , allowing you to maneuver into areas that a monohull cannot, as well as anchor closer to shore . However, monohulls are more maneuverable as you don’t have to deal with two hulls. They can make sharper turns and travel through small channels and small areas easier than cats. In addition, their hull displacements lessen the negative impacts of crosswinds in confined spaces.

Anchoring and Docking

While docking a catamaran is simple, its big size makes it difficult to fit into a standard slip. However, with some skill and good planning, finding room should be no problem. You may even anchor or moor the boat and dock it with the dinghy, which is much easier than a monohull. However, keep in mind that in most cases docking, hauling, and slipping a monohull is significantly easier, takes up less room, and is far less expensive.

Moreover, docking a catamaran can be a challenging task. This is due to the fact that catamarans are frequently too wide to dock in the marina’s core regions. As a result, they must be docked at the far end of the dock. Therefore they have fewer docking options and raise the cost of docking. Owners of catamarans sailing through places where there aren’t many catamarans may find it difficult to find a dock at all. This is especially true in the northern Atlantic, where monohulls outnumber catamarans.

Keep in mind that one of the most significant advantages of a sailing multihull is its stability . Not only at sea, when heeling simply does not – or should not – occur to any significant extent, but also at anchor. It also greatly expands one’s anchorage options to include areas influenced by the swell. This is quite common in the Caribbean, where a slight shift in wind direction may make a previously flat, quiet anchorage intolerable in a monohull. In addition, its fairly shoal draught expands the options even more.

Catamarans have a large platform, making them ideal for relaxing at anchor without the rolling motion that monohulls are prone to in a swell. Many monohull sailors had to leave anchorages because of the uncomfortable anchoring. This is because large rollers or swells entering an anchorage can make the situation extremely uncomfortable and dangerous.

Also, a bridle is tied to both bows and down to the anchor chain on catamarans , resulting in a fairly secure position at anchor . In heavy winds, many monohulls tend to sail at anchor since the bow acted as a sail (due to the high freeboard). They sail in one direction until the chain snatches, then tack across and sail in the opposite direction, almost completely dislodging the anchor. The catamaran, on the other hand, is much more stable at anchor and does not sway as much.

Sailing Abilities

Most cruising multihulls won’t point like a monohull with a deeper keel upwind, and the motion may be rather unpleasant when sailing in rough weather. You must also keep a close eye on the sail area, but we’ll analyze this further below.

Moreover, catamarans are not suitable for racing and sailing sports. They can be fantastic for a holiday or even living aboard, but most racers would never buy one because of the stability. There is no sense of wind, waves, flying, or the boat itself on a catamaran. It’s quite tough to tell when it’s time to reef. While this can be done by feel on a monohull, there is specific instruction for catamarans as to what winds the sail area should be reduced.

When sailing to higher latitudes, like the North Atlantic, then a monohull would be a better solution than a catamaran. Residential areas are easy to heat and keep warm, and traditional metal may even melt thin ice. The contrary is true in the tropical zone, where huge catamaran salons would be unbeatable.

Monohulls can sail higher into the wind than most catamarans due to their keel. Daggerboards, which serve the same role as a keel and boost windward performance significantly, are common in some catamarans. However, daggerboards are not seen on 95 percent of cruising cats (those available for charter). Also, a monohull will be much easier to tack than a catamaran and glide lightly through the water. Moreover, in rougher seas, certain catamarans experience an annoying slapping of water on the bridge decks. A monohull responds to the helm more quickly than a multihull (in other words, they turn faster). This is due to the fact that most cruising cats have small “spade rudders” whose depth is dictated by the need for a modest draft. While with a keel, a monohull can have a more responsive rudder for its draft.

Monohull spreaders are 90 degrees to the mast, however, catamaran spreaders must be backswept. The reason for this is that a monohull has a backstay, and by combining it with the intermediates, you can achieve a lovely pre-bend in the mast. Keep in mind that the pre-bend is to flatten out the mainsail and allow for better performance.

Also, in order to pre-bend the mast on a catamaran without a backstay, you’ll have to utilize the backswept spreaders and diamonds. The reason I bring this up is that if you want to broad reach or run on a catamaran, you can’t let the mainsail out all the way because the backswept spreader tips could puncture the cloth. Because the spreaders on a monohull are at 90 degrees, you can let the main and boom out much wider, which is obviously more effective. This is one of the reasons why a catamaran should broad reach and tack downwind.

Maintenance

Because catamarans have two of everything, there is a clear trade-off between maintenance costs, reliability, and redundancy. One of the most significant advantages of having two of everything is that you have a backup . As a result, even if one component fails, you can typically still utilize the boat, such as running on one engine while the other fails. While redundancy is fine, lower maintenance and repair costs are generally preferable. Although having two of everything provides you some redundancy, I doubt you’ll want to take the boat out if one of the two hulls “fails.” Of course, this means two hulls to clean and antifoul, double the engine maintenance, and so on , but having two of the important pieces of equipment, such as engines, outweighs the disadvantages.

Due to their weight-bearing, catamarans have minimal to no heeling and do not roll at anchor. With sudden gusts, heeling on a monohull can be dangerous and uncomfortable, not to mention seasickness. Again, the trade-off is a noisy ride and fast movement, which many people find uncomfortable in bad weather. However, the heeling action of a monohull sailboat offers stability, spills wind from the sails, and provides safety.

Catamarans, unlike monohulls, do not have ballast in their keels, therefore they rely on beam and buoyancy for stability. Typical cruising catamarans have a beam-to-length ratio of around 50%, while several modern designs exceed this figure. A 45-foot catamaran will be around 22 feet wide, offering a highly solid sailing platform. Monohulls, unlike catamarans, cannot overcome rolling and pitching because of their narrow beam and lead ballast.

Rolling and pitching on a monohull while underway is quite dangerous. But, walking around on the deck of a catamaran while underway is easier because the boat is considerably more stable and does not heel. Sail adjustments and reefing are also significantly easier and safer for the crew as a result of this. The risk of falling overboard on a catamaran is far lower than on a monohull because of the rolling and pitching motion.

Generally, buying a catamaran is substantially more expensive than a monohull. So, if you opt for a cat you should also consider your budget before even starting your research. Pre-owned monohulls, on the other hand, are extremely inexpensive to purchase due to a current supply that considerably outnumbers the demand.

Nowadays, catamarans are in high demand , and they normally keep their worth far better and longer than other types of boats. And that’s why the market is currently centered to manufacture lots of them. Bear in mind that looking for a catamaran under $250,000 your options will be limited, and finding a catamaran under $100,000 is nearly difficult. Unless you opt with older boats like the Prouts or the less priced Geminis, a monohull is your best bet in this instance.

The cost of a cat rises if you need at least two of everything. But, keep in mind that due to their popularity, catamarans have a high resale value and a low depreciation rate , and they normally sell faster than monohulls. Due to the fact that most catamarans are not made in the United States, delivery expenses must be considered when purchasing the boat. Multihulls are becoming more popular, and as a result of the increased demand, they command greater prices in both the new and brokerage markets. Lastly, when considering a purchase, keep in mind that maintenance costs are substantially higher than on a monohull.

Catamarans vs Monohulls – The Bottom Line

So, this is it! We’ve come to the end of this highly discussed topic among sailors. Obviously, everything would be determined by two basic factors: personal preferences and budget considerations. Both monohulls and multihulls have their pros and cons and it’s totally up to you to decide which one suits you best. Because the two types of vessels provide such a different experience, it is highly recommended that you rent and test each one before purchasing to compare everything. In any event, it’s reasonable to say that a catamaran is an excellent choice for a charter, if not for purchase. Despite its high price, it provides comfort, space, and stability but you have a better overall sailing experience with a monohull. So, I hope that this article will help you make the right choice according to your needs. I wish you good luck with your research!

CATAMARANS VS. MONOHULLS

by sailmaui | Oct 27, 2016 | Sailing | 0 comments

What’s the difference?

There are obvious differences between catamarans and monohulls. Most notably, a monohull vessel has only one hull, or main body, whereas a catamaran has two hulls. Because of these two hulls, catamarans typically stay more level than their single-hulled counterparts. They also tend to offer more space, and arguably will go a lot faster. Lets dive in to what differentiates the two types of boats and what makes the Sail Maui vessels so great…

Smooth Sailing

A monohull sailboat, as the name implies, has only one hull, and this hull is generally centered around a heavy keel. A catamaran has two hulls, with the spar and sails in the middle ( amidships in sailor speak). The wide stance of catamarans means they don’t heel much (heeling is when the boat leans while under sail); in fact, a catamaran will rarely heel more than five to ten degrees before you need to reduce sail area. For these reasons, catamarans are especially good for families with young children or older, less agile people because the boats aren’t as susceptible to the wave action and walking around is easier on level ground. While any sailor enjoys the thrill of a monohull heeled over in perfect sail trim, enjoying a beverage on the deck or laying out a buffet lunch is certainly easier with minimum tilt! Seasickness can also be less of a problem on sailing catamarans, & if you’re concerned about feeling uneasy, be sure to read our blog on preventive tips !

Catamarans usually have more space than monohulls, both above and below deck. Though it increases windage, it is nice to have a covered salon area on deck as well as the luxury of spreading out and lounging in the cockpit. Prime seating on Paragon & Paragon II is the netted area in between the hulls called trampolines (no not the bouncy ones) which offer guests a great place to watch for whales and dolphins. This is also the wettest place, as the hulls are always on different points of a wave and sometimes they break under the boat!

Fast is fun!

There’s many benefits to both types of sailboats, and certainly everyone has their preference, but possibly the biggest factor for some in the question of catamarans vs monohulls is that performance built multi-hulled sailboats are able to reach higher speeds. This is due to limited drag and their power-to-weight ratio—in other words, there is a lot of sail power but very little weight and resistance in the water. Depending on the design, catamarans can be up to 25–30% faster than single-hulled boats of the same length. This is of course not always the case, as many of the catamarans you’ll find on Maui are built more for comfort than speed. Sail Maui is the fastest charter on Maui, and we regularly go in excess of 15 knots under sail during our charters in the tradewinds. **This isn’t always the goal, as we take our passengers enthusiasm for fast sailing into consideration before attempting to sail so aggressively!

Monohulls or Catamarans – Which is Best for the Cruising Sailor?

The debate between catamarans vs monohulls still rages, and most boaters are firmly on one side or the other. The truth is, either a catamaran or a monohull can provide a wonderful way to enjoy sailing, traveling, and being on the water.

Both have advantages and disadvantages, and both have large and loud fan clubs. The choice between a catamaran and a monohull depends on your budget, lifestyle, and personal preferences.

My wife and I have owned both types of vessels over the years. After five years of cruising on a Lagoon catamaran, we decided to go old school and bought our current boat—a heavy, full-keel monohull. The catamaran was fun, for sure—but it wasn’t for us in the end. Here’s a look at all of the differences we learned about during our journey.

Life at anchor, life at a dock, life underway, living space, storage space, ride comfort and motion at sea, maintenance time and costs, docking and maneuvering, capsize risk, hull breach scenarios.

Rigging Safety

Rigging Strength and Configuration

Monohull vs catamaran speed, thoughts on catamaran vs monohull for circumnavigation, deciding monohull vs catamaran, faqs – catamarans vs monohulls.

Life on Sailing Catamarans vs Life on a Monohull Vessel

At anchor, a catamaran provides superb comfort and living space. The “upstairs” cockpit and salon mean that boaters can enjoy non-stop wrap-around views. Monohull boaters are stuck in their caves and must peek out of their small portlights or climb into their cockpits to view the world.

A modern catamaran will also have swim steps that make it easy to get on and off the boat and provide easy access to dinghies and water toys.

If there’s an uncomfortable roll or swell in the anchorage, the catamaran’s stability will make the roll a bit less noticeable. Monohull boaters are more likely to be adversely impacted in a rolly anchorage. This does not mean that the cat owners are getting a perfect night’s sleep every evening, however. Catamarans just have a different motion in rocky anchorages, not a lack of motion.

Life at a dock gets a little more tricky for catamarans. Most marinas were built long before the catamaran trend and feature traditional slip sizes meant for monohulls. Marinas have to put catamarans on t-heads or make other accommodations. Therefore, it can be harder and more expensive to find a catamaran-friendly dock.

Once at a dock, the massive space of a catamaran can be harder to heat and cool efficiently. Catamarans usually need several air conditioners or heaters installed, whereas a monohull can get by with only one or two. That also means that cats might need more power (50 or 100 amp service instead of 30 amp) than some marinas can provide.

Monohulls will have fewer issues finding marinas that can accommodate them, and they pay standard rates.

When sailing in protected waters, catamarans usually speed past their monohull friends. A catamaran provides a flat ride and sailors can move around their boats easily to make sail changes as needed. Walking on a catamaran’s deck is undemanding.

Catamaran sailors also have many options to rest comfortably underway. Because catamarans don’t heel over, catamaran sailors can sleep in their usual cabins. They can move about the interior of the boat with ease. Cooking in the galley doesn’t usually look any different underway.

In similar conditions, a monohull will heel over. Some sailors love the feeling of being heeled over and feeling the wind in their hair. Some don’t. It can be more challenging to walk the decks and work sails on a monohull vs a catamaran. While in the cockpit, monohull sailors will want to sit on one side and may even need to brace themselves to stay comfortable. For long trips, there is no doubt that living while heeled over for days at a time is exhausting.

Moving around the interior of a monohull boat at sea is also more challenging. Monohull sailors usually sleep in sea-berths with lee cloths instead of their usual quarters. It would be very uncomfortable to sleep in a v-berth underway, as the bow may be continuously pitching in seas. The lee-cloth in the sea-berth helps keep a resting sailor in their berth instead of falling onto the floor.

Monohull boats have gimbaled stoves. Even while the boat is heeled over, the galley stove will remain level. However, cooking in a monohull while underway is still more challenging than cooking in a catamaran since the cook needs to constantly brace themselves against the heel and rolling motion.

At the same time, none of this is to say that catamaran sailors have it easier at sea. In reality, catamarans may be more level, but they feel every wave in the ocean twice. The result is a choppy, bumpy ride with no rhythm. It can be just as tiring as being heeled over in a monohull.

Catamaran vs Monohull Sailing Compared

Here are just a few ways that catamarans differentiate themselves from monohulls as platforms for living aboard.

Living space—quantity and quality
Storage space and weight
Budget—purchase and routine maintenance
Maintenance
Catamaran vs Monohull for Circumnavigation
Docking and close-quarters maneuvering

Catamarans have significantly larger and often more attractive living spaces. On the other hand, the living space on a monohull is usually small and can be dark due to small windows.

A monohull’s cockpit tends to be small and focused on safety. Families are more likely to feel in each other’s way, and moving around while others are seated can be awkward. On a catamaran, the cockpit is likely to be large and social. Catamaran cockpits have large tables and lots of lounging space in the cockpit.

Catamarans have large trampolines forward, which provides another comfortable, social lounging space that monohulls lack. Many catamarans also feature additional lounge space via the large cockpit roof.

The salon on a monohull is located in the main cabin. A monohull’s salon will be smaller than a similarly-sized catamaran. Often there is a small table, room for several people to sit, and a single sleeping berth.

Catamarans feature a wide bridge deck that crosses both hulls. This large living area features great visibility, ventilation, and natural light. On some catamarans, the galley is located on the bridge deck (called “galley up”), and on others, the galley is located in one of the hulls (called “galley down”).

Monohulls have sleeping quarters in the bow and stern of the boat. On smaller monohulls, the main sleeping area is usually a v-berth. Older, smaller monohulls usually have just one head.

On a catamaran, the sleeping quarters are located in each hull. These cabins often feature regular-sized boat beds and large en-suite heads. Cabins on a catamaran usually offer more privacy than monohulls.

Catamarans are popular with charter companies because large families or groups of friends can enjoy living on a boat together in style and comfort. Each will have a private cabin and a private head. In addition, if you want to find space to exercise, do yoga, or watersports, you’ll find these activities much easier and more comfortable on a catamaran.

Catamarans have more space in general and certainly have more storage space. The additional deck space catamaran designs offer lends to easy storage for larger items, such as paddleboards and kayaks. Catamarans can often hoist and store larger dinghies than monohulls can. Large compartments make storage easy.

However, many catamaran owners are very cautious about storing too much. Additional weight can slow down a catamaran’s performance speeds. With so much space to put things in, it’s remarkably easy to overload a cruising catamaran. Many owners complain about the performance of smaller cats, when in reality they are often just badly overloaded.

Monohulls have less space and less storage. Finding space for big items like water toys can be challenging. But monohullers worry less about weight and freely carry around their cast iron skillet collections—because weight doesn’t impact performance on a monohull nearly as much.

This is a consideration when cruisers consider adding additional equipment. For example, a catamaran owner will have to consider the added weight of a generator and its detriment to sailing speed. In contrast, a monohull owner will have to consider finding space for the new generator.

Some prefer the motion of a monohull while sailing. Monohulls heel over but are steady, and sailors usually get used to the heeling motion. On a catamaran, if conditions are good, the boat won’t heel and will provide a comfortable ride.

When sailing upwind, some catamarans experience bridge deck slamming. Waves get caught between the two hulls and create a slamming motion and sound. It’s hard to predict the timing and strength of each slamming motion, so some catamaran sailors can find it tiresome.

The amount of bridge deck slam varies from boat to boat. Catamarans with higher bridge decks will experience less slamming, while boats with bridge decks closer to the water experience more.

Beyond that often-discussed issue, there is also the issue of the boat’s motion. It’s very difficult to imagine how different the motions are when compared to one another. The monohulls slice through the waves, usually with a predictable rhythm. A catamaran, built lightly to sail fast, feels more like it bounces over the tops of waves. The crew will feel each impact as each hull hits each wave. The result is a choppy, unpredictable motion—but it’s generally flat and level.

Monohulls have been around for ages. Therefore, sailors just starting out can find inexpensive, older monohulls. If you have a tight budget, you’ll probably start looking for a monohull.

Catamarans are newer to the market. Therefore, the initial purchase price of a catamaran is likely to be higher. Monohull buyers can often find a used, well-equipped, comfortable monohull for less than $100,000. Catamaran buyers usually spend upwards of $250,000 for a used cruising catamaran.

Because monohulls have been produced for so long, there is much more supply. The catamaran’s more modern pedigree means that there are always fewer catamarans on the market than monohulls. As more and more customers are drawn to the attractive living space and stable sailing offered by catamarans, demand keeps going up, while supply remains low.

Besides the higher up-front costs, catamarans are more expensive to keep and maintain. A monohull usually just has one engine. A monohull might have one head (bathroom) and will generally have less equipment. Monohulls have less space and storage, after all. Catamarans have twin engines, multiple heads, more hatches—more everything.

With more equipment, catamarans have higher maintenance costs. When a monohull owner services their engine, they have just one engine. A catamaran owner will need to service twin engines. Furthermore, each hull on a catamaran usually has separate and independent systems like bilge pumps, plumbing, fuel, water tanks, holding tanks…the list goes on.

A monohull owner will paint one hull bottom and wax only one hull. A catamaran owner will do everything twice. Therefore, the effort and cost of maintenance are often doubled on a catamaran.

Not only does it cost more money, it can also be harder to accomplish maintenance on a catamaran. You see, catamaran owners have fewer options to haul out. Most older boatyards have travel lifts that only accommodate boats up to 18 or 20 feet wide. Therefore, catamarans need to find a boatyard that has a large enough travel lift or a trailer to haul them. Because there is less supply and more demand for these larger travel lifts, the cost of hauling out a catamaran is often higher.

While some monohulls have lifting or swing keels and can reduce their draft, most catamarans have a shallow draft. This allows them greater flexibility while choosing anchorages. Even if a catamaran and monohull boat choose the same anchorage, the catamaran can get closer to shore and get better wind protection.

One final big difference between these two types of vessels is their ability to maneuver in tight spaces. Monohull sailboats are notoriously difficult to maneuver around docks and marinas. They often have poor visibility from the helm and difficult handling, especially in reverse. The single-engine design often requires a bow thruster, even on smaller boats.

The contrast that catamarans offer is pretty stunning. Even though they appear massive and ungainly in comparison, their twin engines mounted far outboard enable them to spin in their own length. Catamarans can be maneuvered in pretty much any direction using only differential thrust from the engines–all without a bow thruster.

Safety Considerations — Are Cruising Catamarans Safe?

Since most people have only limited experience with these vessels, many people wonder are catamarans safe. Even though they have been making large cruising cats for decades now, most of us have only really played on Hobie cats at the beach. And if there’s one thing we know about Hobie cats, it’s that they’re a lot of fun until you flip it over!

Here’s a look at a few safety considerations and how catamarans stack up against monohulls.

Catamaran stability — capsize potential
Hull breaches and sinking risk
Rigging failures
Designing for speed
Redundancy on board

So, can you capsize a cruising catamaran? The answer is yes, no matter what the fanboys and girls say. It is technically possible but highly unlikely. Cruising cats are massive, and in all likelihood, you’re more likely to break the rigging than flip the boat. But in rough seas and extreme conditions, it does happen even on modern catamarans.

If a monohull encounters strong winds and rough weather, it will heel and roll significantly—but it will keep righting itself. In dire conditions, the vessel could suffer a knockdown. But a monohull will always right itself after a roll—it has tens of thousands of pounds of heavy keel to ensure that it does. Of course, the rig and anything on deck will sustain serious damage in the process, but the boat will be upright in the end.

In the same scenario, while unlikely, a catamaran can capsize. And the catamaran will then remain capsized, with no possibility of righting itself.

One of the scariest risks at sea is that of a serious hull breach, one that a bilge pump couldn’t keep up with. For example, a boat could be holed by an errant floating object or suffer a stuffing box or through-hull failure.

If a monohull sailboat is holed, it could sink straight to the bottom of the ocean. The crew would be left with only a liferaft and whatever they were able to recover before the sinking.

But a catamaran is filled with foam and is (more or less) unsinkable. If a catamaran experienced a hull breach or capsizes, it would take on water and may become less habitable. However, it will still float. In many cases, not much of the boat is left above the water—but it’s still at the top of the water.

Boaters may be able to perform emergency repairs and get the boat to port themselves. Or, they may have to stay with their vessel until help arrives. In either scenario, the crew maintains access to supplies and can stay with a much larger vessel, increasing the likelihood of being found and rescued.

Some catamaran sailors are so certain of their vessels floating in all scenarios that they don’t even carry a liferaft aboard. This is fool-hearty, to say the least, given the crazy and unpredictable things that can happen to any boat on the ocean. But one scenario is equally scary for the monohull or the catamaran sailor and should convince everyone that any offshore vessel should have a liferaft—the possibility of an uncontrollable fire.

Rigging Safety

When wind speed increases, a monohull will heel over. This heeling motion sheds the excess power of the wind. Monohull boaters should pay attention to the weather and reduce sail to ensure they aren’t overpowering the boat. This is why knowing how to reef a sail is so important for all sailors.

However, on a catamaran, the sails and rigging take the increased load when wind speed increases. Catamarans don’t heel, and therefore, don’t shed excess power. If the weather becomes gusty and a catamaran has too much sail up, all that extra power is transferred to the sails and rigging.

This can cause a dangerous situation. For example, there have been reports of catamarans being de-masted in sudden gusts of wind. In a worst-case scenario, a catamaran could capsize if they are over-canvassed when experiencing extreme wind conditions.

Most monohulls have strong standing rigging. The forestay is connected to a solid structure, the hull. This means that the forestay has a strong, stable platform and gives a monohull better upwind performance. Monohulls also usually have backstays, which provide rigging redundancy.

On a catamaran, the forestay is attached to a crossbeam. Because the platform is not as rigid as a monohull’s hull, the forestay is not as strong. In addition, catamarans usually don’t have backstays, and therefore have less rigging redundancy.

The configuration of the rigging is another rigging consideration. On a monohull, the spreaders and shrouds are perpendicular to the mast. Most catamarans come with fractional rigs that don’t have backstays, and their shrouds are set far back. Because of this configuration, catamaran sailors can’t let their mainsails out all the way on a downwind run because the shrouds are in the way. This leads to less efficient sail shapes when sailing downwind.

However, catamaran sailors can rig their sails to sail wing-on-wing. While monohull sailors can also use this configuration with the help of a whisker pole, catamaran sailors have a nice, wide, stable platform to fly large downwind sails.

There’s no doubt about it–catamarans sail faster. Most articles and comparisons state that catamarans are about 20% faster than a similarly sized monohull. Catamarans have a lower wetted surface area and less drag than monohulls. They’re especially nice to sail in light winds, conditions that heavy cruising monohulls tend to not do well in.

While most cruising cats can’t sail upwind as high as monohulls can, they still win the race. However, if a catamaran has daggerboards and a good sail inventory, it can point as well as a monohull.

Many boat owners believe that speed equals safety, as you might be able to outrun an impending storm. That’s a debatable strategy since weather systems often move faster than any cruising boat can move. It has a lot more to do with planning and the decisions made by the skipper, in the end.

Furthermore, more speed means a rougher ride. A heavy, full-keeled monohull might not move very fast, but the sea-kindly and forgiving ride means a more comfortable and better-rested crew. This only goes to illustrate that the “more speed” argument is far more of a personal preference than many sailors admit—especially when it comes to long-distance cruising.

A faster boat provides a skipper with more options, but it does not ultimately equal inherent safety. That will always come down to the skipper and the crew, and the choices they make. A slow boat in the hands of an experienced and careful crew will always be safer than a fast racer under the command of an inexperienced and green crew. In other words, there is no replacement for seamanship and careful planning.

Catamarans have two of everything. While this does equal double the cost and maintenance, it also provides redundancy. If a monohull’s single engine dies and there is no wind, they may have to call for a tow or wait for wind. If a catamaran’s left engine dies, sailors can just continue on the right engine.

Twenty years ago, the majority of boats completing circumnavigations were classic bluewater monohulls. Monohulls are considered safe and capable circumnavigators.

But today, catamarans are establishing themselves as the more desirable choice for many circumnavigators. Catamarans are fast, stable, and capable of crossing oceans. In addition, catamarans can carry significant supplies and offer redundancies. Plus, the extra space that catamarans provide also means that the crew will enjoy watersports like diving, paddle boarding, and surfing.

Since nearly all traditional routes are downwind “milk runs,” catamarans naturally excel along the way. If you take a look at the competing boats for the World ARC rally for the last few years, a definite trend is growing. More catamarans compete every year. Common entrants include Lagoon 450s and Antares 44s.

One of the most significant decision points when thinking about catamarans versus monohulls is your budget. If your budget is under $100,000, a monohull will be your best bet. If your budget is between $100,000 and $250,000, you can consider a smaller, older catamaran. Catamarans such as PDQs, Prouts, and Geminis will be in your budget. If you have a budget of over $250,000 and can afford higher dockage and maintenance costs, you can consider a catamaran.

Next, consider your comfort level. To try it out, you might want to charter both a monohull and a catamaran. Check out a sailing vacation in the BVI or with a company like Cruise Abaco. Taking classes at our local sailing school might also be helpful. https://cruiseabaco.com

Many folks are attracted to the larger, more comfortable spaces of a catamaran. However, some people feel more seasick on a catamaran and can’t get used to the motion. So a lot of your decision will come down to personal preference.

If you can’t imagine squeezing into a darker, smaller cabin in a monohull, then a catamaran might be calling your name. On the other hand, if you are a traditionalist who loves heeling and boats with a lot of teak, a monohull might be your dream boat. It’s just impossible to know how a boat will make you feel until you’ve experienced both.

Boaters often discuss the compromises involved in boat choices. Whether you choose a monohull or a catamaran, there will be some compromises involved. However, no matter which boat you choose, you can enjoy smooth sailing, beautiful anchorages, and some adventure along the way.

Which is better monohull or catamaran?

Both monohulls and catamarans are popular choices for cruising sailors. Which one is better depends entirely on your personal preferences and which boat is more comfortable and appealing to you. If you are on a tight budget, a monohull is your best choice. On the other hand, if you love large open living spaces, a catamaran will be the better option.

Which is safer catamaran or monohull?

When wondering are catamarans safe, always remember that the primary determinant of the safety of a vessel is its captain, not the vessel itself. Both monohull sailboats and cruising cats have important limitations that their skippers must know and abide by.

Some consider catamarans safer because they are virtually unsinkable. If it has a hull breach or capsizes, it will still float.

Others see the sea-kindly monohull to be the safer bet, as they are better designed to protect their crews from the elements in severe weather. They also cannot capsize, as their ballast provides a righting moment in all conditions. But on the other hand, if a monohull experiences a hull breach, it can sink.

Can catamarans handle rough seas?

Modern cruising catamarans are built strong enough to cross oceans and survive in all kinds of conditions. It might be an uncomfortable ride, but not an unsafe ride. In the end, it is the skipper of the boat who ensures its safety at sea. Good seamanship makes a far bigger difference in how a boat handles rough seas than the design of the boat does.

In extreme conditions, such as hurricanes or sudden gusty winds, catamarans can capsize. Once a catamaran has capsized, it won’t right itself. However, it will still float, although upside down. Heavy seas are more likely to cause maintenance and chafing issues on both catamarans and monohulls.

The popularity of the multihull (aka catamaran or cat) fishing boats has never been greater, as more and more boatbuilders enter this growing segment of the market. The inherent stability of the catamaran design rolls less with the seas, making fishing offshore less tiresome and more comfortable. Available from 20 to 48 feet, catamarans typically offer a large fishing platform with generous storage and fishing amenities. They are available in a wide variety of deck layouts, including center-consoles, dual-consoles, and even pilothouse and express variants.

Big Picture

The large deck area of a catamaran enables many large underdeck storage lockers and insulated fish boxes in the sponsons. This gives anglers ample room for gear and the day’s catch. The catamaran’s stability, fishability, and smooth ride in rough seas make it attractive to anglers as well as day-cruisers. A center-console version adds 360 degrees of angler access to the rail. With the dual-console design, generous seating behind a beam-to-beam windshield makes for a great family fishing-friendly setup.

Live bait is one of the most popular types of fishing in virtually every coastal zone. To do it successfully requires optimal water capacity and proper flow. The minimum size of the outflow water plumbing should be twice the size of the inflow. The plumbing should have a drain at the bottom to shed scales at the end of the day, as well as a drain at the top of the well to adjust capacity and allow overflow. Above-deck transom-mounted wells should fully flood to the lids when running to keep baits from getting beat up.

Tip: A sump box with multiple pumps in case a pump fails is the best setup for first-rate livewells. Conveniently located inflow and outflow valves make it easy to optimize the flow without tiring your bait from swimming too much in the well.

Rod Storage

Having enough rod holders is essential to be successful for opportunity fishing. Look for vertical rod storage along the console and across the back of the T-top. Many models also have rod holders along the outboard transom wall. Having plenty of gunwale rod holders for drift- and kite-fishing is helpful.

Tip: Placing adjustable swivel rod holders by Gemlux makes deep-dropping, lure-fishing and drifting even easier because they allow your rods to face the direction the baits are fishing, yet they can be swiveled back to keep rods from sticking out of the boat while running and docking.

Manufacturers often offer multiple choices for horsepower, but whatever the choice, the engines must come in pairs. For example, you might order twin outboards (one for each sponson) or four outboards (two for each sponson), but single- or triple-outboard configurations are not common on a cat. Optimal selection should be made based on user load, weight of the boat, ride comfort , performance desires, and best case for resale. It’s a rare day when you can run wide open, but having more horsepower gives better torque at slower speeds and thus better control. Running larger engines slower gives better fuel efficiency too.

Tip: When possible, choose the highest horsepower offered because it typically leads to a better resale value with a shorter sales cycle.

Power steering from engine manufacturer Optimus or SeaStar is essential with the higher horsepower required for larger boats, and it makes installing and operating the upper station in a tower far more practical and comfortable.

With the power demands of electronics, livewell pumps, stereo amps and more, it is wise to have at least two house batteries, and for larger boats, a third or fourth with a multibank charger for dockside. Each engine should have its own dedicated battery as well.

Electronics

Typically choosing the largest screen or multiple screens that will fit on the console is best-case scenario for ease of use, ergonomics, and visibility. VHF radios, stereo controller, and equipment switches for lighting, pumps, and accessories should all be integrated with greatest visibility and ease of operator reach.

A Tale of Two Hulls

A catamaran rides on pair of hulls, or sponsons, each thinner and sharper than that of a similarly sized monohull boat. The narrow sponsons of the cat tend to slice easily through water to deliver a smooth ride, even in rough seas. At the same time, with the sponsons positioned out to the sides of the boat, cats tend to roll less, thus providing great stability to enhance crew comfort, security and safety. However, cats tend to corner more flatly than a monohull, and some hulls (but not all) tend to lean outward versus inward during a turn.

Experts Say

Newer designs such as Invincible’s Morelli and Melvin-designed semi-asymmetrical sponsons eliminate some of the negatives of the cat design, such as “sneezing,” where water sprays out the front of the boat when hitting a wave. They’ve also controlled the uncomfortable “outboard lean” sensation common in older designs when in a turn. Once transitioned to a catamaran, many become true believers and preach the benefits of the design.

Editor Says: Saltwater fishing cats not only offer superb stability and smooth ride, but some also display exceptional speed and range. I recall one trip out of Key West, Florida, aboard an Invincible 40 Cat with four 350 hp outboards to the Dry Tortugas. It was a 60-mile run, and we made it there in 70 minutes. We caught more fish than our arms could bear, and then dashed back to Key West, arriving in time for cocktail hour on the same day. -Jim Hendricks, Staff Editor, Boating and Fishing Group

Catamarans - Monohulls: Pros and Cons

With catamarans vastly popular in the charter industry, and showing no sign of abating, let's compare the pros and cons of monohull and catamaran strictly on the charter work point of view . The reason why this distinction is important – and I write this as a monohull fanatic myself - is because for charter companies, catamarans are in huge demand due to the overwhelming number of advantages they offer. Out of charter use, there is no question for me that, when the offshore going gets tough, I would much rather be on a solid monohull than on a catamaran - although the catamaran builders have come a long way to strengthen comstruction. But this is just a matter of opinion!

Catamaran Pros

On deck The cockpit, highlight of catamarans, is usually huge, since it spans over both hulls. The cockpit and the salon are on the same level, which enhances the feeling of light and spaciousness, along with the typical huge panoramic windows. The foredeck area is very large as well and sports a big pair of nets between the hulls, the notorious trampolines, which make a great sun bathing area. In any case, it is a great observation spot and a kids' favorite. As a result of this roominess, a catamaran rarely feels crowded, as it is relatively easy to get some seclusion and quietness from other members of the party. Most cats are equipped with dinghy-davits at the transom, which is absolutely great: no more towing the dinghy, thus no more drag on the boat speed.

Down below The catamaran will provide you with considerably more room than a monohull almost everywhere on the boat: in the cabins and in the salon. Besides, there is ample headroom everywhere. A typical 43/47 ft. cat will have 4 large staterooms, with rectangular queen-size beds – no more of those pointy beds! - each with en-suite bathroom. A 38 to 42ft. will have 3/4 staterooms and 2/3 bathrooms. Most cats have an enormous salon/cockpit combination capable to entertain about 20 people in style! Because of the cats’ layout configuration, there is full privacy in every cabin and one does not hear anything from one cabin to the other.

Stability The key fact is that catamarans have a phenomenal stability: they do not heel under way and do not roll at anchor. This usually makes seasickness a non-event. Incidentally, it makes it somewhat safer for kids running around. Whether at anchor or under way, a catamaran is always much more stable than a monohull. Stability is also a good factor for elderly people and/or first time sailors. As a matter of fact, a catamaran will give the latter an excellent impression for their first cruise, instead of memories of being seasick!

Speed & maneuverability There is no question that catamarans are faster under power or sail. Whatever your cruising goals are, catamarans will usually move you about more quickly than a monohull. Catamarans have shallow drafts. This means catamarans can get into places monohulls yachts often cannot reach, and that they can also anchor closer to shore. However, more and more charter cats now have small "sacrificial" keels to improve close-hauled performance. Lastly, I personally enjoy the phenomenal maneuverability of the cats. With 2 engines spread apart, you can pivot a cat of any size literally around the boat's central axis – and without the help of the rudders. The autopilot works particularly well on cats, on a tracking standpoint.

Catamaran Cons

A hard-core monohull sailor once said: "When I sail a cat, it feels like I am driving my living room!" He meant that a cat does not convey the "real" feeling of sailing, with the "rail in the water" as sailors say. That is precisely because a cat does not heel, whereas a monohull does, and sometimes a lot. So if you are in for hard, pure sailing, you will not get that felling on a cat. Only a monohull will give you the full experience!

A cat does not typically sail well upwind and needs a different technique for tacking and anchoring. ( See tips for cat handling ).

It is often said that anchoring a catamaran can be more difficult. This is due to the fact that catamarans have more “windage” than monohulls, and, without keel and ballast, they have a tendency to “bob” on the water when a gust hits. ( See tips for cat anchoring )

Obviously, catamarans take up twice as much docking space as monohulls. This can be a bit of a problem in chartering areas where spending nights in marinas is a necessity.

If you are bringing with you a party of first-time sailors, or older people, or people who could feel apprehensive at sea, you probably will better off with a cat.
