Tri-Hull Boat [What Is It and Its Pros and Cons]

There are many different kinds of boats like flatboats, V-hull boats, bass boats, and pontoon boats. But have you heard of a tri-hull boat?

A tri-hull boat has the standard ‘V’ hull bottom but two additional hulls on both sides. This boat has greater stability than most ‘V’—bottomed boats because of this particular design. However, its ride is rougher on choppy water since there is an increase in the surface area at the bow.

The tri-hull boat design has been most used for boats with lengths ranging from 10 to 12 feet. Shorter boats will enjoy the advantage of the greater stability that this boat design offers. Tri-hull boats are mostly smaller, dinghy-style boats and are commonly used by recreational fishermen on placid lakes.

Read on to learn more about tri-hull boats, their pros and cons, and why they are not so popular today.

Tri-Hull Boat

If you are like most people, you may not know that there is such a thing as a tri-hull boat. You may have already been surprised by boats with two hulls, such as the catamarans. But three hulls? You may think that that is overkill. But it was a popular design choice for a while.

Tri-hull boats are basically ‘V’-hulled boats that have two additional hulls on both sides aside from the main ‘V’ hull at the middle. If you look at a tri-hull boat at the front, you will see that it has a bottom shaped like an ‘M.’

This design gives greater stability to the boat. However, because of the larger surface area at the bow section, its ride is rougher when running on choppy waters. This boat design is used largely in lake boats and smaller dinghy-style boats. The lengths of these boats usually range from 10 to 12 feet only.

Tri-hull boats are also called Cathedral and Tunnel hull boats. They are very popular with r ecreational anglers and sport boat aficionados. Due to their design, these boats are very buoyant, stable, and can get on planes faster.

However, when speeding, these boats tend to pound upon encountering choppy water. Its design makes it unsuitable in non-flat water. That’s why they are ideal for calm bays and placid lakes.

Additional Description of Tri-Hull Boats

These boats are called tri-hulls simply because they have three hulls at their bottoms. Their original designers based their tri-hull designs on the traditional double-outrigger hull watercraft from the Philippines and East Indonesia, including other cultures in the Austronesian parts of Southeast Asia.

These boats are also called trimarans. Most of these boats are built for a tournament or sports use and recreational boating and fishing. In the past, this boat design was also used in building warships and ferries.

Modern technology and later developments have led tri-hull boat makers to improve their basic design to enhance their performance, speed , and buoyancy. In general, these boats are classified as multi-hulls, in the same category as the tri-hull pontoon boat and the catamaran.

Tunnel Hull Boats

Others have called them tunnel hull boats because they also form large tunnels at their bottoms when running on the water. They are very similar to V-hulled boats but only with a more pronounced bottom shape.

With their particular hull design, tri-hulls have less contact with water, so they have more buoyancy and lesser drag. As such, they are faster than most sailboats with traditional hull designs. With three hulls at the bottom, they tend to have more deck space. Boaters can also expect these boats to provide excellent stability.

Advantages of Tri-Hull Boats

There are many advantages that tri-hull boats offer more than what the boats with more conventional hull designs can provide. Here are some of these advantages:

1. They Sail Flatter

The three hulls of these boats make them sail flatter. They won’t even heel when you are making a turn. In certain sea conditions where a monohull boat will be rolling, the tri-hull will stay flat.

2. They Sail Faster

There are three hulls in these boats, not like other boats with just one hull. That means the load is distributed across the three hulls of the boat instead of just one. The hulls of tri-hulls are higher in elevation from the water compared to most conventional boats.

That means less boat is in the water. This kind of boat position reduces drag. So, this boat can go faster than conventional boats, all things considered. The tri-hull design allows a boat to use less force to cut through waves to sail faster.

3. They Won’t Sink Easily

The three hulls of tri-hull boats are lined with flotation materials like closed-cell foam, unlike conventional boats with only one hull. This means that if a tri-hull boat flips, it will not easily sink as other mono-hull boats.

4. They Have Greater Stability

Tri-hull boats have wide and flat hulls. This translates to improved stability. Ordinary boats wobble on the water as people are boarding. You will not experience this same thing with a tri-hull.

In fact, you can move around the deck of a tri-hull, and you won’t be able to make the boat tipsy here and there. Enhanced boat stability is very advantageous to skiers, weekend fishers, and pleasure boaters.

5. They Have Greater Buoyancy

When you are on the deck of a tri-hull, you will feel it has greater buoyancy than other boats. The middle hull provides 90% of the boat’s buoyancy, while the two hulls on both sides provide stability.

This long and narrow middle hull has two functions: it keeps the boat afloat, and it helps to get the boat to the plane much quicker than other boats. If you step on the metal, the tri-hull will zoom away and reach the plane much faster.

Getting the boat to the plane or planning is a process. As you rev the engine, the boat goes up on a plane or level on the water. If the boat is traveling on top of the plane of the water, its bow is lifted out of the water.

6. They Have More Space

Tri-hull boats have more space on the deck than other boats. That is the natural result of having three hulls at the bottom. This feature made these types of boats trendy in the 60s. Moreover, the government used the design to build warships and large ferries at that time.

7. They Weigh Less but Can Carry More Weight

Unlike large boats, tri-hulls have smaller cross-decks. This means that they don’t need as many supporting structures to make the structural integrity. As a result, they can hold or carry more weight while weighing much less than boats with a single hull.

8. They Are Cheaper to Own and Operate

All things considered, these boats are relatively cheaper to own and operate. They cost less than boats of the same size but with different hull designs. These boats require lesser power than other boats with different hulls, so your need for fuel will be lesser as well.

Disadvantages of Tri-Hull Boats

However stable and buoyant a tri-hull boat is, it still has some disadvantages that you shouldn’t ignore. Here are some of them:

1. They Are Not for Choppy Waters

Tri-hulls are not very good at sailing on choppy waters – at any speed. But you can minimize the pounding if you will run ‘bow high.’ But remember that once you are out of calm waters, the tri-hull will shift to and fro and make you wish you are on land instead of the waters.

2. Wet When Running

When the tri-hull is running, they tend to be a bit wet. If you are on the upwind side, you really need to wear a raincoat. You will get more than the spray time you wish for on the deck of a tri-hull each time the hulls slapped the water down hard.

3. Not Very Good for Fishing

Though tri-hulls may offer great stability for parties and barbecues on deck, some think they are not fishing-friendly. However, some also believe that a tri-hull fishing boat can be used as an angling platform, especially with families and small children.

4. Not Good for Open Waters

Tri-hulls do not fare well in the open ocean. They tend to have choppy rides that will get those who are aboard wet. That is why most tri-hulls, especially the smaller versions, are used ideally only on calm lakes and rivers.

Why Tri-Hulls Are No Longer Popular?

tri hull fishing boat

While tri-hulls were very popular in the 1960s, they are hardly known today. They started to lose their steam during the 1980s. Why? There are some reasons why these types of boats have lost their popularity:

1. They Have Been Over-Modified

Through the years, the basic design of tri-hulls was altered and heavily modified to become multifunctional. The unwanted result was the loss of the initial tri-hull design. The makers of this boat replace it with a more modern tri-hull boat design.

2. Their Incredible Buoyancy Was Their Unmaking

Tri-hulls are excellently buoyant on calm waters but not on choppy waters. Once you are out of sheltered waters and you are in open and choppy waters, your tri-hull will wobble and bob along with every chop that comes its way.

Their long and narrow center hulls are why most parts of these boats float on top of the water. This feature is will result in a very comfortable ride on calm and peaceful waters, but not on choppy and rough waters.

Tri-hulls will bob on the water with every large wave that comes their way. The constant up and down motions became undesirable to most tri-hull owners over the years. They opted for more comfortable boat options.

3. The Unmasking of Tri-Hulls’ Limitation

The revelations of the limitation of tri-hulls influenced its future market potential. When boating enthusiasts got hold of the tri-hulls, they knew that these boats do not perform well on choppy and rough waters. Interest in these boats waned and eventually disappeared.

Pleasure boaters and anglers don’t want to be limited on the types of waters they want to explore and enjoy. Thus, investing money on a boat capable only on calm waters seemed to be a losing proposition.

4. Wet Ride

This is another factor why tri-hulls lose their steam. When a boater insists on riding it on rough waters, they need to be prepared for a wet ride. And it appeared that not too many boaters would like that kind of ride in a pleasure boat.

These boats are not V-hulled, so they can’t cut the waves. If a tri-hull hits powerful waves, the water will slam hard against the amas or the two outriggers on both sides of the boat and spray the water all over the deck.

To counter this condition, many boat manufacturers modified the design of their tri-hulls. Instead of rigid amas, they made them foldable so their tri-hulls will fare better on rough waters.

With this modification, a tri-hull can be easily converted into a V-shaped hull or monohull. However, this modification resulted in the loss of the original tri-hull design.

5. Not Worth the Investment

The cost of a boat is very much like the cost of a house. That is an investment that needs careful thought and deliberation. Who would want to invest in a boat that only offers a pleasurable ride on peaceful waters but not on ocean waters where most boaters want to go?

Conclusion: Tri-Hull Boats

A tri-hull boat has the conventional ‘V’ hull, but it has two additional hulls on both sides. There is greater stability on this boat than most ‘V’-bottomed boats because of this design. However, due to the increase in the surface area at the bow section, the ride of this boat is rougher on choppy water. This is one of the major reasons why tri-hulls lost their popularity in the 1980s.

Again, to help you further assess Tri-hull boats, here are their advantages followed by disadvantages:

  • Sails Flatter
  • They Sail Faster
  • Won’t Sink as Other Boats
  • They Have Greater Stability
  • Have Greater Buoyancy
  • They Have More Space
  • Weigh Less but Can Carry More Weight
  • Cheaper to Own and Operate

Disadvantages of Tri-hull boats

  • They Are Not for Choppy Waters
  • Wet When Running
  • Not Very Good for Fishing
  • Not Good for Open Waters

Catamaran vs Trimaran: Choosing the Perfect Multihull Vessel

26th mar 2023 by toi williams.

Rightboat logo

The debate over whether catamarans or trimarans are better boats has been going on for a long time without resolution, but the reason is understandable. The truth is that despite their many similarities, catamarans and trimarans have distinct characteristics that set them apart from each other, so each type of vessel offers a distinct boating experience. The catamaran vs. trimaran debate largely boils down to personal preference and how you intend to use the boat. Here are some of the things you need to consider when choosing between a catamaran and a trimaran. 

What Is a Catamaran?

A catamaran is a multi-hulled boat that has two twin hulls connected by a structure supported by a wide beam. Catamarans come in a wide variety of sizes, ranging from small rowing boats to large boats that are big enough to be used as car ferries. The structure connecting the two hulls can be anything from a simple frame with webbing to a superstructure that includes cabin and/or cargo space. Most of the recreational catamarans for sale are designed to hold two to 20 passengers.

What Is a Trimaran?

A trimaran is also a multi-hulled boat, but it has three hulls instead of two like the catamaran. The middle (main) hull is larger than the two small outer hulls attached to it. These hulls are connected by a lateral beam, wing, or some other form of superstructure, depending on the model. These types of boats also come in a wide variety of sizes, ranging from recreational yachts to ferries. 

trimaran

Advantages of Catamaran vs. Trimaran

The advantages of catamarans vs. trimarans are mainly based on comfort. Catamarans are spacious boats, known for their large living quarters with plenty of room on board for hosting gatherings and parties. Their popularity has enticed many boat builders to create increasingly luxurious designs on larger and larger boats. The catamaran also has a more classic style that appeals to those who want a boat with a simple, sleek shape. Catamarans are best suited for boating in calm seas, lagoons, and shallow waters.

Advantages of Trimaran vs. Catamaran

The advantages of trimarans vs. catamarans mainly come down to speed. Trimarans are among the speediest boats available, offering lightning-fast speeds on open waters. Many recent winners of notable boating competitions have been won by boaters piloting trimarans. These boats also perform well when heading upwind and are remarkably stable with their three-hulled design. The anchoring gear is installed on the main hull and is easy to deploy. 

Trimaran vs. Catamaran Speed

In the trimaran vs. catamaran speed debate, the trimaran is the clear winner. For long offshore races, trimarans have become the preferred vessels, and boaters piloting trimarans have won the Jules Verne Trophy in every race held since 2010. This is because of their unique design, which has speed and safety qualities that provide significant benefits for boaters. 

The trimaran's third hull makes the boat considerably faster than any other hull form due to the correlation between the boat’s waterline length and its speed. Having more hull distance in the water lets the boat reach higher speeds. Trimarans can also be pushed harder and are more forgiving than other boat styles in racing environments.

That doesn't mean that catamarans are slow. Some styles of catamarans are capable of breaking world records when the boating conditions are right. On downwind runs, a racing catamaran may be quicker than a trimaran, but for overall speed in various conditions, the trimaran comes out on top. 

Catamaran vs. Trimaran Performance

In the catamaran vs. trimaran performance debate, both sides have their advantages. A catamaran is easier to handle and maneuver with the boater having to handle the lines and halyards less often. However, this ease comes at the expense of speed, with cruising catamarans generally traveling slower than comparable trimarans. 

Trimarans are more versatile in their performance, and they perform better than a catamaran when traveling against the current or the wind. Trimarans can be used in nearly all weather conditions, are less vulnerable to drifting, and have less roll motion than a catamaran. However, handling a trimaran requires more work than handling a catamaran, which can be exhausting over long periods of sailing. 

Trimaran vs. Catamaran Efficiency

When comparing trimaran vs. catamaran efficiency, the differences are minimal. Multi-hulled boats are more fuel-efficient than comparable mono-hulled boats due to their hull forms and their lighter weights. Multi-hulled boats also tend to have smaller displacement and shallower drafts than other boat styles. 

The biggest difference in trimaran vs. catamaran efficiency is that catamarans nearly always have twin engines while trimarans generally run with one engine. A trimaran also has less hydrodynamic resistance than a catamaran because it spreads out the displacement across three hulls instead of two. This allows each hull to be narrower and more streamlined.

catamaran

Catamaran vs. Trimaran Stability

The stability of multi-hulled boats is one of their biggest advantages over mono-hulled vessels. Multi-hulled boats benefit greatly from their wider stance on the water, and their wide beams and floats offer higher stability than a ballasted keel. Multi-hulled boats are also more buoyant because their floats help prevent immersion. When comparing catamaran vs. trimaran stability, the better boat will depend on the conditions on the water.

A catamaran's geometrically stabilized design reduces both heeling and wave-induced motion, providing a stable platform underway and at anchor. However, the catamaran's design is not as suitable for navigating heavy seas as the trimaran's build. The trimaran's three hulls provide excellent stability even in rough waves, but this can also make a trimaran less comfortable than a catamaran when the water is calm.

Catamaran vs. Trimaran Safety

Both catamarans and trimarans are considered to be safer on the water than mono-hulled boats. A catamaran has superior resilience and roll inertia that makes capsizing extremely unlikely. Its speed, steadiness, and ease of motion due to a lack of ballast also contribute to increased safety.

Trimarans are considered the safest multi-hulled boats because their three-hulled design makes them almost unsinkable. Many also have a core made of high buoyancy foam, helping them stay afloat even in the most brutal storms. Weight centering and a complete anti-drift scheme also make the boat safer for everyone aboard.

Trimaran vs. Catamaran Maintenance

Comparing trimaran vs. catamaran maintenance costs shows that many of the costs will be very similar for both types of boats. These costs include yearly boat service and repairs, annual haul-outs, and insurance coverage but exclude major upgrades. You will also have to budget for dockage, winterization, and storage for each year if you don't intend to use the boat year-round. 

Boaters are advised to budget between 5% and 10% of the boat's value for annual maintenance costs if their boat is less than five years old and a little more if the boat is older than that. Different maintenance jobs can be charged in different ways. Sometimes, the charges are based on the length of the boat while other charges are based on the number of hours worked.

trimaran

Catamaran vs. Trimaran Cost

If you are looking for an affordable seafaring vessel, catamarans and trimaran are both good choices. There are many reasonably priced catamarans and trimarans suited for families as well as other models that provide more luxury for an additional cost. The materials that the manufacturer used to build the boat and the electronics included will also impact the price of the boat.

With so many different factors impacting the cost of different boats, you should choose the best vessel for you based on the features you want as well as your budget. Doing some research using the information on Rightboat's listings will help you find the right combination of quality and affordability you are looking for. Because we offer both new and used boats, nearly any boater will be able to find a boat in our listings that fits their needs. 

Choosing between a catamaran and a trimaran may seem simple at first, but the different sizes, styles, and amenities offered can make the choice much more complicated than you would think. If you prefer comfort and ample space while cruising, a catamaran may be the better choice. However, if you like speeding across the water and enjoy the thrill of racing, then a trimaran may be your best option.

Whichever boat you decide to purchase should fit your specific circumstances and requirements. Start the decision-making process by deciding what the primary use for your new boat will be. Will it be used more for family cruising or sport fishing? What bodies of water will you be boating in? Are you planning on staying close to shore or taking the boat into deeper waters? All these factors will impact whether you should choose a catamaran or a trimaran. 

With Rightboat's listings, you can learn about the features of the latest catamaran and trimaran models and see what you can expect to pay for the boats you are considering. You can sort through our listings by price, age of the boat, length of the boat, or listing date and then narrow down the results of a search using the rest of our filtering tools.

What is a tri hull boat

What is a Tri-Hull Boat?

' src=

Table of Contents

Boats have three basic hull types; monohull, catamaran, and trimaran. Tri-hull boats are really a hybridization of a trimaran and a monohull boat. The design uses sponsons on either side of the main hull to add buoyancy and width at the bow , which adds interior volume. 

In essence, a tri-hull boat is a deep V hull with sponsons that are part of the main hull that go all the way to the bow in older designs. This gives them the appearance of having three separate hulls, but they don’t. Instead, the front of the boat has three individual bow sections, and the stern is one solid hull from port to starboard .

Even though the hulls are not entirely separate, as they are on many sailing trimarans, tri-hull powerboats have some of their qualities. The hull form offers more buoyancy and space; however, the triple bows tend to pound when driving into a chop on powered tri-hulls.

Popular in the 1970s and 1980s, the only tri-hulls in production today are small fishing boats of less than 18 feet and deck boats. The tri-hull design makes them stable platforms to fish or party. 

What is a Tri-hull?

Richard Cole, a Naval Architect, first designed the tri-hull boat in 1958 while employed with  Thunderbird Boats in Miami.  Also known as a cathedral hull. It was revolutionary. The early design had three distinctive hull forms and a bow as wide as the stern. This hull shape offered more buoyancy and stability than monohull boats . 

It is a single hull boat with sponsons that protrude from the hull. However, a tri-hull does not have three separate hulls. Instead, it has a deep V center hull with three distinct bow sponsons, which blend into one hull as they go aft, providing added buoyancy. 

Today, Tri hulls are used predominately for deck boats. Their wider bows offer added buoyancy and space for extra seating, giving you a large platform that can accommodate many guests. Tri hulls are also stable while anchored and underway, making them comfortable for the non-boating type.

Deck boats still use a tri-hull because they are stable and have a wide bow that offers extra seating space and buoyancy. However, the bow form of many bass boats is a modified tri-hull design. Over the years, boat builders have taken Mr. Coles’s original design and used modern fabrication techniques to perfect what he started. 

What are Tri hulls good for?

Tri-hulls make an excellent platform for deck boats because they are wider in the bow. In addition, the sponsons offer stability, so the boats are stable when sitting still and when underway. In addition, many people use their deck boats as social centers, and a tri-hull offers a very stable platform for your family and friends. 

The tri-hull has also found its way into the hearts of small boat owners. The stability of the hull form makes a great casting platform for anglers. In addition, a few small tri-hulls on the market are less than 18 feet long and economical to get on the water. 

Although most manufacturers have gone to deep V hulls, you can still see the relics of the tri-hull form in the bow of many boats. They have been highly modified since Mr. Cole designed the first tri-hulls. However, boat designers have improved the initial design since it does add buoyancy instead of doing away with it entirely. 

Most boats were still being built from wood in the late 1950s, but construction of boats from fiberglass began in earnest in the 1960s. Mr. Cole created his tri-hull boat designs from this new material, and his tri-hull plans came from a drawing board, not a CAD/CAM program. Imagine what he might have done with a computer and carbon fiber.

Who made tri-hull boats?

The original design of tri hulls tended to pound when driven into the waves, offering a rough, wet ride. In 1970, Richard Cole went to work for  Wellcraft Boats  in Sarasota, Florida, and took his tri-hull design to the next level. When the Wellcraft Airslot went to market, it was an instant success.

With the Airslot concept, Mr. Cole took the outward sponsons of his original design, shortened them, and gave them a more hydrodynamic shape. The result was a line of boats that Wellcraft sold for over two decades.

Skeeter Boats is another company that invested in tri-hull boat design and production in the 1960s. They still produce bass boats, bay boats , and deep V boats built for offshore ventures. If you look at the lines of their current fleet, you will see vestiges of the tri-hull form in the shape of their bows. 

In the 1980s, boat manufacturers found that composites allowed their imaginations to run freely, and hull shapes of today attest to those imaginings. 

What is a Tritoon boat?

Tritoon  is the brand name of a three-hulled pontoon boat. Boats with three distinctive hulls are also called tri hulls or trimarans. The third hull gives the boat the ability to carry more weight and offers more stability. The Tritoon is not the only three-hulled pontoon boat in production. However, it is the original, and has three distinctive hulls (pontoons), is very stable, and can carry quite a load.

Pontoon boats have a reputation as being rather sluggish. However, the Tritoon is the first pontoon boat with the performance of a deck boat. In addition, the third hull and the unique shape of its pontoons allow for the addition of more power than can be used by comparable tri-hull pontoon boats. The added power can get you home quicker when storm clouds gather on the horizon.

What is your boat type?

Whatever your desire to get on the water, a boat is made for you, and finding the right one may take a while. However, if you want to take a group of friends boating with you, a deck boat or Tritoon can carry a crew and enough gear to make a day of it.

Whether you want to buy a new boat and need a way to help pay for maintenance, or you would like to try different types of boats, Boatsetter has you covered . Boat owners list their boats and rent them by the hour and day, bareboat, or with you as the captain at the helm .

If you don’t want the responsibility of boat ownership yet have a desire to get on the water, you can  rent a boat from a boat owner near you . Whatever your choice, getting out on the water makes an ordinary day special.

Catamaran Vs. Trimaran (The 5 Differences)

Posted on May 30, 2022

If you’ve been on a catamaran before and you’re intrigued after hearing there are vessels with three hulls too, then you’re right. Early warning, however, is that these are two different vessels even though some of the differences aren’t obvious.  

However, when it comes to catamaran and monohull, most boaters are familiar with the distinctions between the two. However, it might be hard to tell the difference between a catamaran and a trimaran since the latter’s third hull does not necessarily make an obvious difference in some functions.

They differ in anchoring, steering, accommodation, safety, and speed. Catamarans have two hulls and trimarans have three. Catamarans, on the other hand, are easier to handle at a marina and offer a higher level of comfort and space. In contrast, trimarans are very fast and more fun to sail.

Whether you’re planning to cruise on one or make a purchase, to help you decide, I’ve put together a list of the pros and cons of each option.

Catamaran Vs. Trimaran

  • The hulls(#1 difference)
  • Affordability and convenience
  • Anchoring 

We’ll look in-depth at the differences between a catamaran and a trimaran so that you can make an informed decision. First, let’s go through the different types of multihulls.

catamaran

A sailing vessel having two parallel hulls is known as a catamaran . The wide beams of a cat’s paws are often used to stabilize the animal. Ballasted keels are used to stabilize monohull vessels. Displacement and hull volume of catamarans are all smaller than those of comparable-sized monohulls, as is the depth of the draught.

Catamarans date back to the 1600s when their earliest known variants appeared. Those in Tamil Nadu’s Pavaras community mostly used them for fishing, preferring them to other fishing vessels because of the added stability that the dual hulls gave. Twin-hulled boats were introduced by the British and quickly became a worldwide phenomenon.

Current Catamarans are far more advanced. There are two key ways in which they’ve grown in terms of their versatility, construction, and design.

Small Waterplane Area Twin Hulls (SWATH)

These are catamarans capable of piercing the ocean’s surface !

It is common practice to have the hulls of a SWATH catamaran underwater. As a result, they are less susceptible to the swells of the ocean, which is excellent for maintaining stability while sailing in severe waters. SWATH layouts have been utilized on rescue and research vessels in the recent past.

In contrast, their wave-piercing counterparts feature low-buoyancy bows attached to the twin hulls of their twin vessels. Catamarans with hulls that pierce waves rather than ride on top of them are faster in rough waters than SWATH catamarans. Passenger ferries, military vessels, and yachts have all recently made use of wave-piercing cat designs.

trimaran

Double-outrigger trimarans are multi-hull boats that have two tiny “floats” (technically, they are outrigger hulls) on either side of the larger “float” that is joined to the larger “float” through side beams. Trimarans are extremely stable because of this design, which makes it difficult for them to capsize even in the most choppy of waters.

For centuries, the Austronesian people have used triangular-hulled fishing boats, which are currently the most frequent type of hull in Southeast Asia. There are still few warships and ferries that use double outriggers in their designs, but they are rare.

Catamarans Vs Trimarans

Because a catamaran has three separate hulls, it is distinct from a trimaran, which has two.

2. Affordability and Convenience

The shape of a cat is great for accommodating and providing comfort. You can get a large nacelle built between the two load-bearing hulls, providing additional living space . A huge cockpit and two cabins are located on either end of the boat’s hulls. This layout is ideal if you’re searching for a bit of privacy as the celebration goes on in the saloon.

Modern catamaran flybridges provide additional areas for entertaining and resting . Catamarans don’t heel much, which means that you can cook and do other things on the deck without fear. Cats can also carry a fair amount of weight, so you can stock up on food and gear if you’re going on a long trip.

Trimarans indeed have some advantages over catamarans when it comes to livability. It is difficult to perform activities like cooking onboard a boat with a dog since they tend to heel more than cats do. Catamarans, on the other hand, can handle significantly more weight. Approximately 45 feet is a good starting point (14 meters). 

Trimarans, which are the same size as cats, can only carry about half the weight of a cat. Catamarans, on the other hand, offer more spacious and pleasant living quarters than trimarans.

When purchasing a boat, one of the most important considerations is how simple it is to overturn in the event of a storm. If you plan to spend more than a few hours on the water, you’ll want a boat that isn’t easily flipped or sunk because sea conditions can change quickly.

Three hulls are preferable to two when it comes to safety. A trimaran is more stable since it has one main hull and two overhangs on each side. With the side overhangs, it is less likely that the boat will turn over when it is hit by a heavy breaking wave on the side. 

To further enhance stability, trimarans are constructed with the bulk of the weight concentrated on the main hull. A thorough understanding of multi-hull stability is essential for safe sailing!

What causes a catamaran to overturn?

Trimarans are designed to float even if they capsize. It also implies that a capsized trimaran will be easier to notice from the air, which might be the difference between life and death in an emergency.

Due to the widespread usage of closed-cell foam in trimarans during the past decade or so, this is the case in nearly every new model. Most trimarans can be sliced in half and still float, thanks to this type of construction.

Catamarans are more stable than monohulls, but they can’t compete with a trimaran when it comes to boat handling. If a catamaran and a trimaran were subjected to storms of equal intensity, the catamaran would be more likely to capsize than the trimaran. 

Catamarans, on the other hand, are not inherently dangerous. Because they have the same closed-cell foam as a trimaran, they are nevertheless more difficult to flip over than monohulls.

While we’re talking about safety, it’s worth noting that trimarans don’t require as much attention when it comes to reefing. Catamarans have a lower heel angle, which means that most of the additional wind power is transferred to the rig, increasing speed. 

To maintain a cat sailing flat, you must time your reefing carefully because the pressure on the sail practically quadruples as the wind speed doubles. Reefing a trimaran is similar, except that the boat’s modest heel offers you greater leeway in timing.

To most people who’ve ever had the opportunity to sail on one of these boats, the trimaran wins hands down. Tiller-steered trimarans, in particular, have a great reaction to the helm. They have a small heel that resembles a monohull, but the heel’s arc is restricted.

A catamaran is quite stable, but it does not roll. The thrill of sailing is enhanced by heeling, even though it’s frowned upon by those who prefer the comfort and convenience of a boat. 

Trimarans combine the heel of a monohull with the stability of a catamaran thanks to their three hulls, making them the best of both worlds when it comes to sailing. If you want to practice your helming skills while having some fun, a trimaran could be a better choice. 

4. Speed 

main characteristics of a catamaran hull

Tri-hulled boats outperform their twin-hulled counterparts in speed. When it comes to speed, trimarans are often lighter than catamarans, thus they require less sail time to reach double-digit speeds. When equipped with centerboards/daggerboards, a trimaran can maintain a formidable course upwind (as is often the case for modern models).

In comparison to a monohull of the same size, a catamaran falls short of the trimaran in sheer speed. Just because tris tend to focus more on performance does not mean that catamarans are any slower.

5. Anchoring

maintenance

It is easier to anchor a trimaran than a catamaran since the ground tackle can be kept in the main hull and deployed from there.

Catamarans, on the other hand, are better suited to marinas since they are more maneuverable. In addition, docking lines are handled more easily by these devices.

A catamaran is a better option than a trimaran if you need to accommodate a large group of people on board for an event like a party. However, a trimaran is an excellent choice for thrill-seekers and sailors who like to challenge themselves on every stable platform. Whichever you choose, enjoy!

Catamaran Vs Trimaran

Catamaran Vs Trimaran | Life of Sailing

Last Updated by

August 30, 2022

As boatbuilders make faster and more luxurious multi-hulls for cruising and racing, it is time to settle the debate: Catamarans vs. Trimarans.

Catamarans and trimarans have distinct characteristics regarding comfort, sailing performance, safety, and personal preference. The dual- or tri-hull designs both confer significant advantages over traditional monohulls and each fill an amazing niche in the sailing world.

Though both are based on traditional Austronesian outrigger canoes, the dual-hulled catamarans and tri-hulled trimarans have distinct design goals that make them ideal for very different purposes, and it is important to take into account your goals when trying to decide which to sail! We’re going to discuss both types as they rate across performance, safety, comfort, and possible uses. There is no one solution to this age-old problem, but we can help you understand which design is best for you!

From boatbuilder releases to the history of their development, it is important to access lots of sources when trying to make this decision. As a performance sailor, my heart is always in the speed and upwind abilities of the trimaran, but modern catamarans are dynamic and incredibly comfortable. Still, in my opinion, anything that gets you on the water is a great boat, so let’s find the right one for you!

Table of contents

‍ Sailing Performance and Safety

While most traditional boats over 20 feet are monohulled keelboats, there are major limitations to the type of sailing you can do with a monohull. First of all, monohulls depend on their keel to keep them upright, which is effective, but the force of the wind almost always causes the boat to heel to leeward by angles of up to 25° under reasonable cruising conditions, which can be quite uncomfortable for the crew! This design, which relies on giant lead ballast in a deep-set keel, is vulnerable to capsizes and, in drastic cases, sinking.

Additionally, the single-hull only provides so much volume for accommodation and storage, while the more horizontal layout of the multi-hulls can increase cockpit and cabin sizes substantially. Beyond that, both types of multi-hull can experience higher speeds at a given hull length than monohulls.

So how do cats and tris compare to each other? Well,

Catamarans: Stability and Ease

With their dual ‘pontoons,’ Catamarans make use of their floats to always remain on a flat and consistent angle of heel, rarely sailing under more than 10° of heel. This distribution of floatation also makes it nigh on impossible for them to capsize, though the distance between the hulls can make it a problem in the rare cases that they do flip. They do suffer a bit from not having any wetted surface underneath the center of effort, causing them to slide sideways while sailing upwind and making it difficult for them to beat tight angles to the breeze. While they make up for this with speed on the reach and downwind, catamarans are an inferior option for trying to make progress upwind in heavy sea and wind conditions.

These tradeoffs do come with some advantages. Unlike monohulls, catamarans have very shallow drafts, allowing cruisers to sail close to shore without concern, and their common dual-motor design allows them to maneuver incredibly well in tight spaces with a built-in backup for single-engine failure. They heel minimally because of the horizontal distribution of weight, and this means that they are incredibly stable and comfortable while underway or at anchor. In addition, their sail plans and maneuverability characteristics do make them easier to sail with a smaller crew, requiring fewer highly experienced sailors in your party.

Trimaran: Speed and Safety

While traditionalists have finally come around on the aesthetics of the dual-hulled catamaran, the tri-hulled lines of trimarans can still be a bit of a shock to viewers. They combine the vertical stability and upwind capabilities of a monohull with the speed and lateral stability of a catamaran.

When it comes to performance sailing, modern trimarans are well ahead of any other hull design. Due to the relationship between speed and the ‘waterline length’ of a boat, i.e. that more hull length in the water leads to higher speeds, the third hull actually makes trimarans drastically faster than any other hull shape at a given length. Most current speed records, including those for circumnavigation, instantaneous velocity, and single-day distance, are held by Trimarans. In competition, the 2013 America’s Cup is a perfect example of the superiority of Trimarans over Catamarans in terms of speed, as the challenging Trimaran from Golden Gate Yacht Club handily beat the defending Spanish Catamaran in a best-of-three series. With their signature central hull, they can make better upwind progress without drifting and often heel even less than contemporary catamarans.

Further, trimarans far outclass both catamarans and monohulls in terms of safety. The central hull gives the trimaran that signature central righting moment from monohulls, while its winged pontoons provide it the lateral balance that makes catamarans so safe themselves. Combined, this gives a modern trimaran a righting moment of 27°, which is almost impossible to reach in any breeze condition because of the pontoons. For a comparison, modern cats can only maintain 12° of heel before flipping, which is not entirely uncommon in heavy seas.

Therefore, in a purely technical sense, trimarans are safer, speedier, and more rewarding. Still, to reap these benefits you often need to be a little more prepared to engage with the more advanced aspects of sailing, and the tri-hull design does make some sacrifices in other areas.

Though performance is an important metric for all sailboats, every added knot of speed or degree of heel comes at a price of comfort, and it is here that we need to consider the full implications of that cost for both cats and tris.

Catamaran: The Ideal Platform

When it comes to comfort, space, and luxury, it is hard to bet against the catamaran. Because of the geometry of the dual deep hulls and built-up central platform, catamarans offer the ideal vessel for a large crew, a party yacht, or a comfortable getaway vessel. They heel minimally, are highly stable at anchor, and the central platform can be carefully built to maximize the area between the wings. Most catamarans can offer the living space and horizontal area of much larger monohulls, making it the ideal choice for a pleasure cruise.

Trimaran: The Cost of Speed

For all their advantages in terms of performance, the hardware required for the central hull subtracts substantially from the accommodations that are available for a cat of the same size. New trimarans, like the Neel 51 which made waves back in 2017, are pushing back against this perceived comfort gap, the large central hull with the two performance-oriented wings does make it harder for tris to haul the same amount of weight and provide comparable space as most cats.

Preferences

The beauty of modern sailboats is that design advances in both catamarans and trimarans make it possible for all sailors to find the exact right boat for them. Speed demons who want to sail tight to the wind and feel that rush may find themselves enticed by the capabilities of the newest Trimarans, while cruisers looking to get the biggest space for the length are still thrilled by how fast and stable modern Catamarans are off the breeze. While no one would complain about being invited to a cruise on a new Trimaran, you can certainly fit more of your friends in the spacious decks of a Cat.

Both multi-hull styles excel at maneuvering in small spaces and shallow waters, perfect for island hopping or inland sailing. Their wide platforms, which can run a slightly higher cost at marinas than comparable monohulls, enable stability without sacrificing performance. Both are regarded as incredibly safe in nearly all conditions, though Trimarans do have the slight edge in truly nasty weather.

In the end, it all comes down to how you want to sail and what is going to make a good trip successful! For those looking for a leisurely cruise with a minimum of work and a maximum of space, find the most spacious catamaran you can, and don’t worry about missing out on speed as you’ll more than hold your own off the breeze. If you’re excited to go fast no matter what direction the wind is coming from, with the knowledge that you’re nigh on unsinkable, a performance trimaran is the way to go!

Happy Sailing!

Tri-Hull Boat – What Is It and Its Pros and Cons

Lots of people like to spend time beside the water and many like to spend time in, or on, the water. If you like spending time on the water, you’re going to need a boat.

People have used boats for time immemorial. Since 70% of our planet is water, we’ve had to find ways to cross the ocean and other stretches of water.

Boat design has advanced so much with technological advances, and the use of ever-more complex materials, that modern boaters have a tremendous choice when it comes to buying a boat.

In the 1960s, the tri-hull boat was a very popular choice. It has many redeeming factors and a few issues.

Unfortunately for tri-hull boats, the issues, and the fact that other boat types are just more appealing to modern boat buyers, has seen a decline in demand for tri-hulls.

Let’s find out more about these boats and why they’re not so often seen sailing the waters as they once were.

Example of Tri-Hull Boat from photo archives

What Makes A Good Boat?

A good boat is a boat that is designed effectively for its purposes. The key factors in boat design are the materials used in its production, its design or aesthetics, the technologies employed, and the features that are built into the boat’s design.

If you want a boat that does what it should, appeals to buyers, and is up-to-date, economical, and environment-friendly then these key factors need to be fully optimized.

Despite all the innovations and changes in materials used in boat design, the structural, holistic, and technological factors have remained consistently integral. Boats need to float. That’s obvious.

But how they float, how they can be powered to move over the water and through waves economically, and how they can accommodate their passengers while doing so, is the crux of the matter.

The use of the boat is going to be put to will have an overriding influence on design, materials, features, and aesthetics. A boat that is going out to war has very different specifications from one that you want to spend a lazy day on at your local lake.

In today’s boat market, aesthetic appeal and technological aspects determine design requirements. However, underlying everything and always and forever the trump card is structured.

The structure of the boat has to be the motivation behind everything because a boat is made to go out on the water and the structure is what ensures it floats and stays afloat.

Structure And Design

Boat design has to ensure safety, no matter what the boat is used for, but the use of the boat will determine design and technology. For example, hydrodynamics and aerodynamics are integral to yacht design.

There’s a lot of mathematics and physics in boat design. Erosion, corrosion, and chemical analysis have to be factored in. Structural and architectural analysis has to be done.

Hull Design

The hull design is about materials, shape, and size.

Hull shape depends on the boat’s purpose and the type of water involved.

The main types of hulls are deep-v hulls, associated with offshore and rough water, and flat-bottom hulls, associated with smooth water.

Deep-v hulls have a wedge shape. They aren’t appropriate for shallow water. They require more power due to low buoyancy. They perform well in rough waters, knifing through waves. Offshore sport boats and bulks have deep-v hulls.

Flat-bottom hulls favor shallow and smooth waters. They have a very low deadrise and maximum stability.

Multihulls, such as tri-hulls, are less deep and suit small boats doing offshore or lake sailing. They are flatter at the stern and deeper at the bow. They usually have smaller engines.

Hull dimensions vary depending on boat length, width, height, and angles.

Computational techniques are employed to locate and scale hull segments.

Aesthetic Appeal

Once structural requirements have been met, aesthetic appeal is going to inform a lot of the design decisions that work alongside structural aspects. The aesthetics will depend on the use that’s going to be expected of the boat.

Boats of any type need to be ergonomic and they need to optimize efficiency in operation. The human and social sides of the boat’s use need to be kept in the frame.

People are investing good money in a boat. They want a boat that is aesthetically appealing. That’s just the way people are. People want things to work but they also want them to look and feel good while they work.

Aesthetic appeal is associated with mental well-being and things like taste, status and so on and so forth.

This aspect of boat design and manufacture has really gone through some major changes. Traditionally, boats were made from wood, steel, and iron.

Iron and steel are strong but they are heavy so are not well suited to small boats. Iron and steel are only really suitable for huge ships and cruise liners.

Materials most commonly used are steel, aluminum, fiber-reinforced plastic (FRP), polyethylene, and carbon fiber . Aluminum is lightweight, facilitating speed without compromising the strength or integrity of the hull.

Aluminum is preferable for smaller boats and even smaller ships. Yet aluminum is expensive and it involves high maintenance costs including aluminium boat repainting with special marine paint for aluminium boats .

There has been a real shift towards fiberglass. Fiberglass is glass-reinforced plastic or fiber-reinforced plastic. Fiberglass, or FRP boats , are reliable, light, extremely effective, capable of high speeds, enjoy a longer life, have low maintenance costs, and are able to resist corrosion.

Polyethylene is used mainly for boats for professional fishermen because it’s buoyant and chemically resistant.  

Carbonfiber is strong and light. It’s stable for a long time, both chemically and thermally.

It resists abrasion and corrosion. Carbonization of the fibers during manufacturing strengthens and stiffens the material. Carbon fiber is generally used for racing yachts because it lowers weight and is moldable.

The advances in technology that are now integrated into boat design are amazing. Boats today give their users the sort of smooth ride and comfort boats users of the past could never have dreamed of.

Technological advances in navigation and the advent of location software have vastly increased levels of safety. Advanced personal safety devices give people security on the open water they never used to have.

Thermal imaging has revolutionized boat use. Having automated controls has changed the entire experience of controlling a boat.

The fact that boat manufacturers are seeking to produce boats that are environmentally friendly is absolutely crucial to the survival of our planet and its beings.

Sustainable boat design, the use of renewable energy to fuel boats, and advances in how we reuse and recycle hazardous waste, in a bid to limit the human tendency to treat the ocean and other waters as waste deposit sites, cannot be applauded enough.

We need to keep on finding ways to design boats that do not impact the environment in which they operate.

Buyer’s Mindset

There are various types of boat buyers who are looking to buy a boat for personal, and often emotional, reasons. These psychological needs have to be factored in along with practical needs.

The boat buyer wants a boat that will appeal to him or her, make him or her feel happy when they’re on it, serve the purpose the buyer has in mind and fit the buyer’s budget.

Types Of Boats

Types Of Boats 1024x683 1

There is a vast array of boat types: flatboats, V-hull boats, bass boats , pontoon boats , and tri-hull boats to name a few.

The Tri-Hull Boat

The original tri-hull design was based on traditional boats used in some southeast Asian countries which have a double-outrigger design.

Tri-hull boats have the standard ‘V’ hull bottom along with two additional hulls, amas or outriggers, one on each side. This design feature means that the bottom of tri-hull boats looks to be shaped like the letter ‘M.’

Having the three hulls, instead of the one hull that most boats have, gives the tri-hull boat a larger surface area at the bow.

Tri-hull boats may be referred to as trimarans, Cathedral boats or Tunnel hull boats because of the large tunnels formed with their more pronounced bottoms when these boats move through the water.

Tri-hull boats are classified as multi-hulls and are categorized in the same category as the catamaran and the tri-hull pontoon boat.

They range in length from 10 – 12 feet. Tri-hull boats are usually smaller boats, similar to dinghy-style boats, but the tri-hull design has also been used on ferries and warships.

Tri-hull boats are particularly popular among recreational boaters , tournament or sports users. The stability of these boats is good so they are great for parties on deck.

Some recreational fishers really like the tri-hull and others don’t. They can make for a good angling platform, liked by those with young children and families.

There have been improvements in the performance, speed and buoyancy of tri-hulls with modern technology and later developments but the boat has never really regained the popularity it enjoyed in the 1960s.

Pros: Tri-Hull Boats

A flatter sailing experience.

The design of tri-hulls means they don’t tip to one side when they turn and they don’t roll in the way a monohull does in certain sea conditions.

The overall result is that when you’re on a tri-hull and the water is not choppy, you can have a very peaceful sailing experience.

A Faster Sail

Load is distributed over the three hulls instead of over just one hull and the boat sits higher in elevation from the water. This means less of the boat is in contact with the water.

Drag is minimised and the boat doesn’t require as much force as a monohull boat to cut through waves. Consequently, you can have a speedy ride in a tri-hull boat.

Flotation materials, such as closed-cell foam, within the three hulls make tri-hull boats significantly harder to sink than mono-hulls. Good to know when you’re out at sea or in the middle of a vast lake!

Enormous Stability

Having such wide, flat hulls gives tri-hull boats impressive stability on the water. The two side hulls are mostly responsible for this enhanced stability, providing increased surface area at the bow.

There’s none of that wobbling about when people step onto the boat and, once on deck, you can move around comfortably without feeling like you’re going to capsize the boat. Shorter boats enjoy more stability.

Buoyancy Extraordinaire

The middle hull, which is long and narrow, does most of the buoyancy work – 90% of it. The design makes good uses of flotation materials and the layout works to the advantage of buoyancy.

Great For Getting To The Plane

The long and narrow middle hull helps get the tri-hull to the plane quicker than for other boats. When the engine is revved, the boat rises up on a plane, or level, on the water and then travels on top of the plane with its bow lifted out of the water.

Spacious Deck

The three-hull design really opens up the deck.

Lightweight But Load-Bearing

Tri-hulls have smaller cross-decks so they don’t require as much in the way of supporting structures as monohulls in order to have structural integrity.

This means the boat weighs less than monohulls but its spacious deck means it can carry more than monohulls.

Tr-hull boat engine design depends on whether the boat is a small sailboat size or a large ferry. Usually, they have a high horsepower outboard motor and can reach good speeds.

The fact there’s less drag because the boat has less contact with the water means the boat can accelerate better and reach fast speeds quicker than many other boats.

This speed is ideal to plane the boat on the surface but not so great when it comes to cutting through waves, due to the design.

Tri-hulls are generally cheaper to buy than other boats of the same size and require less power to operate because less contact with the water means more buoyancy and less drag.

Cons: Tri-Hull Boats

Hull design issues.

Modern materials decrease the weight and increase the speed of tri-hulls and other multihulls. Required buoyancy decreases, allowing smaller section hulls and amas.

However, as the hulls become increasingly narrow and achieve ever higher speeds, the risks of damage to the cross-sectional areas increase when these boats smash into big waves.

The cross-sectional points close to the attachment for the forward aka of the ama can be fractured.

In 2012 the Sodeb’O design opted to use the main hull’s larger cross section as the longer hull. The reduction in length of the amas means their cross-section can better cope with imposed loads.

Even smaller tri-hulls are potentially compromised by the design and construction of composite, moulded akas.  

Not Good On Unsettled Water Or Open Water

When on unsettled water, the boat takes something of a pounding from the waves. Running the boat ‘bow high’ can help.

Deck Gets Wet

Tri-hulls are not v-hulled, which means they aren’t good at cutting waves. When the tri-hull encounters a large wave the wave slams against the amas or outer hulls, on both sides of the boat, causing a lot of sprays. When sailing on the upwind side, you will get wet each time the hull hits the water.

Over-Modified

Tri-hull boats have been modified over the years to embrace multifunctionality, but, in the process, they’ve lost the original tri-hull design. Instead of rigid amas, more modern tri-hull designs have made the outer hulls, or amas, foldable to convert the tri-hulls into a V-shaped hull, better able to handle the waves. The modification has helped but the original tri-hull design has been lost.

Limited Use

Many boat buyers want a boat that copes well with varied water types and the tri-hull is not great for open water or any water that’s unsettled.

The large cross-decks and extra hulls require extra materials in production, which can increase the price. Despite this, tri-hulls tend to be cheaper than many other boat types.

However, if you have a tri-hull and want to use it on choppy waters you may have to invest in a larger motor. Modified tri-hulls with foldable amas and a massive center hull cost more.

Tri-hull boats are beautiful and provide a stable, spacious experience for those spending time on tranquil waters. However, issues with the design have arisen largely due to unceasing modifications aimed at resolving issues with choppy water.

Unfortunately, the modifications may help solve some issues but they open up others at the same time.

Tri-hull boats are still manufactured by a number of brands but their popularity has definitely waned. The tri-hull design is found in limited sailboat models nowadays.

Another very pertinent reason for the waning interest in tri-hull boats since the 1980s is increasing interest in v-hull boats and deck boats. There have been great advances from the 1980s that have ensured that v-hull and deck boats are increasingly desirable for all water types and boat users.

An offshoot of this has been a decline in demand for tri-hulls. The rise in popularity of pontoon boats is also influential. There is potential for tri-hulls to come back if a hybrid model , that’s recently been designed, takes off.

This hybrid model uses wave momentum as the source to power the tri-hull.

Three hulls better than two – how the Neel 51 trimaran is challenging its many twin-hulled competitors

  • Toby Hodges
  • June 6, 2017

The Neel 51 may have turned plenty of heads at La Grande-Motte boat show in April, but can three hulls really offer the style and accommodation expected these days of a luxury performance multihull?

tri hull catamaran

Neel has found a clever niche offering the performance benefits of a trimaran with the type of accommodation offered in a cruising catamaran. This new trimaran, the Neel 51, was the most talked-about multihull at La Grand-Motte boat show in April, and of the year so far.

The La Rochelle company argues its trimarans are more stable than cruising catamarans. Cats, it says, reach their peak righting moment at 12º heel, beyond which sail needs to be reduced.

That peak for a tri, however, is not until 27º heel – an unusually steep angle for cruising. Neel also argues that trimarans are faster, particularly upwind, thanks to a more rigid forestay (attached to centre hull) and more central weight management.

The Joubert-Nivelt design incorporates the best assets of Neel’s previous 45 and 65 models – that of performance and comfort in a bluewater family yacht – and adds even more space for its size.

The Neel 51 is quite a beast in the flesh. Her 9m beam (26cm wider than a Lagoon 52) helps support Neel’s signature coachroof design above the hulls and contributes to sumptuous living space.

Fine reverse bows give confidence in her ability to perform. Neel argues the 181sq m upwind sail area on the 51 is larger than any other equivalent cruising cat – yet its 107sq m usable space (living and storage combined) is much larger than competitors too.

This design primarily targets living space however. A focal point of the 51 is its sliding doors that stow away completely to leave an open, single-level cockpit and interior saloon. It is a concept that Neel has dubbed ‘cockloon’ – a strange-sounding word that fails to significantly differentiate this from the likes of catamarans by Bali and Nautitech, which are also based on these open designs.

The word does, however, help draw attention to a wonderfully large inside/outside saloon area. Neel President Eric Bruneel pointed out how the stiffness of three hulls allows for such a wide open bulkhead.

“We really wanted to have the cockpit working with the saloon,” he told me. Unfortunately, the downside of his ‘cockloon’ solution is the small external cockpit space.

The main deck level includes a vast galley forward (with prime views), and, as per past Neel models, the owner’s cabin shares this amazing deck-level outlook. The other three double cabins are all large and each comes with its own heads. Two forward berths can also be specified.

I particularly appreciated the mechanical/engine room below the saloon. It is like a ship’s engine room, with 7ft headroom, plumbing on one side, electrics to the other and the single saildrive contained in its own area aft. Bruneel argues that one prop pushing one hull is more efficient than typical catamaran set-ups and says the 75hp saildrive propels her at a cruising speed of 9 knots.

Fitted-out on the water the Neel 51 weighs 15 tonnes – over 10 tonnes lighter than the Lagoon 52, but a similar weight to the new Catana 53. The first 51 to launch reportedly achieved 290 miles in 24 hours during the first delivery, with jib and three reefs – and will hit the mid-teens with relative ease.

Neel’s build quality has also seen much-needed improvement with this new model. The three hulls are infused in one shot. That requires ten days to prepare the 160sq m of moulds for a two-hour infusion. As Bruneel admits, it’s a big step-up in technology for them.

Neel has built 23 of its 45ft model and is now building one boat every two months in its new La Rochelle facility.

Trimarans are known for their speed and excellent performance. However, not every vessel performs well in the ocean’s rolling waves, which begs the question – are trimarans able to handle rough seas?  

Trimarans are seaworthy because their tri-hull construction makes them incredibly stable, even in the roughest sea conditions. They are lightweight, very buoyant, easy to handle, fast, and resistant to capsizing. Trimarans also have a shallow draft. 

So, let’s get into the details and discuss why trimarans are an excellent choice for seafaring. I’ll tell you more about the features that make them safe and ideal for traversing the oceans. So, let’s get into it.

What Makes A Trimaran Seaworthy? 

tri hull catamaran

A trimaran is seaworthy because of its wide base giving it capsize resistance, its high speeds allowing for outrunning storms, and good maneuverability, making transiting stormy areas with precision, safer.

I’ll describe these factors in more detail below: 

Buoyant Construction

One of the most important factors making trimarans seaworthy is their buoyant construction. 

Modern trimarans are made from two lightweight fiberglass layers with a foam core, giving them exceptional buoyancy. 

This should be seen in comparison to their lead keel counterpart, the monohull.

Trimarans also consist of various sealed parts, allowing them to remain afloat if one or more parts become damaged in a collision. If the worst came to the worst and the ocean obliterated the entire trimaran, there would still be buoyant pieces to act as rafts for the crewmembers to hold onto. 

Many trimarans also have watertight crossbeams between the hulls, further increasing their buoyancy. 

If the trimaran were to become filled with water, any of its hulls would be able to keep it afloat. 

tri hull catamaran

Catamarans are known for their excellent stability, and if they heel (lean over with wind-filled sails), they can right themselves up to a 12° angle before flipping over. 

To understand when a catamaran or trimaran will capsize, I suggest you read this article: Why Catamarans Capsize .

On the other hand, Trimarans are well-known for their righting torque (the ability of a vessel to right itself before flipping over). These vessels can reach a 27° angle before they flip over, but the trimaran will likely remain floating even if this happens. 

So, although they heel more than cats, and studies suggest they would capsize “more easily”, they are very stable.  

This stability and ability of trimarans to keep themselves upright are due to their wise base. Just like when someone pushes you, you take a step to widen your base, so do the trimarans amas (the floats to either of the side of the center hull).

This means that the wind’s force can push harder on the sails before it flips, harder than if it had a narrow base (monohull or cat).  

With its tri-hull design, a trimaran’s weight is distributed primarily on the middle hull. This mid-central balance provides a lot of vertical stability for the vessel, but the two outrigger hulls (a.k.a. amas, connected via lateral beams) give added sideway stability. Its multi-directional strength allows a trimaran to remain stable even in the roughest seas. 

While monohulls are heavy and tend to go through the waves, trimarans are light and go over. This means higher speeds but also a different more bumpy ride, at least while going into the wind. 

A trimaran’s three hulls will contact the wave at different points. However, because their hulls are slimmer than a monohulls, they can slice through waves more easily but will lack the kinetic energy to drive through.

Shallow Draft

tri hull catamaran

A boat’s draft refers to the distance between the bottom of the boat and the waterline. Trimarans have a very shallow draft due to their lightweight construction, hull design, and buoyancy. 

A trimaran’s shallow draft means that it will be able to sail in waters that monohulls can’t. This allows for more shallow water harboring options, something that can be very useful when a storm is approaching.

Maneuverability

Lightweight and responsive steering means not only that a trimaran is fun to sail, but it also allows for more precise maneuvering. This is not only useful in marinas when navigating tight quarters, but it is also essential when transiting large waves at the right angle. 

Capsizing Resistance

A trimaran’s design makes it very unlikely to capsize as it has a fast-draining deck, open-weave wing nets, and a wide base. 

The fast-draining deck and cockpit have drainage holes to help prevent waterlogging in extreme conditions.

Trimarans also have open-weave wing nets to help decrease windage and reduce the amas susceptibility to digging into the water when waves crash over it.

As noted above, the trimarans main feature, the wide stance, allows for more power to the sail before there is a need to reef. This means higher speeds!

Speed is not a primary factor contributing to seaworthiness, but speed can improve a boat’s safety in storms. 

If the trimaran encounters a dangerous storm, its high-speed capability allows it to move out of the stormy area faster, decreasing the chances of an accident. 

Safe Cockpit

Trimarans usually have sealed or partially sealed cockpits with windshields, allowing the captain and crew members to navigate the vessel comfortably, even in extreme weather conditions. 

A trimaran’s protected cockpit also helps keep the vessel’s essential navigational equipment safe during stormy conditions, contributing to its seaworthiness. 

Final Thoughts

So are trimarans safe in rough seas.

Are you in the market for a new boat and considering a trimaran? If so, you may wonder how safe they are on rough seas. 

Trimarans are safe in rough seas because they have high righting torques, and conditions have to be extreme before they flip over. They have excellent vertical and lateral stability due to their tri-hull design, and their buoyant construction helps keep them afloat. 

Trimarans are some of the speediest vessels out there, and in rough seas, they can move out of the stormy area and into safety. They are also easy to handle and have protected cockpits, making them safer to use on rough seas. 

Trimarans are seaworthy because they have three hulls, giving the vessel excellent stability, even in extremely rough seas. They consist of lightweight and buoyant foam-core material with multiple sealed sections to allow them to float if one or more parts become damaged. 

Trimarans can quickly move to shallow harbors in storms with their shallow drafts and high-speed ability. 

Trimarans are easy to handle, and their sheltered cockpits make it easy for the crew to navigate them expertly through the sea. The cockpit or deck is unlikely to become waterlogged because of the drainage.

Folding System

Legendary ability, unbeatable reliability.

Folding and unfolding a Corsair trimaran takes only a minute. With just 4 bolts to remove, it is easily managed by one person, and is normally done while afloat. Simply raise (to fold) or press down (to unfold) the inboard end of one cross beam. It can be done from the safety of the cockpit and only a little force is needed due to the folding system’s carefully balanced geometry, and the movement of the floats being mostly horizontal.

The solid aluminium folding struts have absolute control over the folding motion and prevent flexing or racking. A stainless steel bolt on the inboard end of each beam secures the floats for sailing. Crucially, wingnets remain attached during the folding process – their frictionless fixing allows them to tension themselves appropriately through the folding process. The system is so simple and balanced that Corsair trimarans can even be folded while motoring.

TRAILERING ACROSS CONTINENTS

Corsair Marine trimarans are especially weight-conscious, and sit low on their trailers meaning they have excellent trailering characteristics. They are equally easy to launch, giving you more time on the water, and the ability to expore many more remote cruising grounds or participate in regattas far from home. Some Corsair trimaran models go from trailer to water in 25 minutes, and with practice even the largest boat models can be done in 40 minutes.

Tri Hull Boats: Why They Lost Popularity

Jonathan Holmes 5.0 Rated 5.0 out of 5 5.0 out of 5 stars (based on 40 reviews)

Table of Contents

You might have heard about pontoon boats, bass boats , V-hull boats, and even flat-bottomed deck boats, but have you heard about tri-hull boats? What about trimarans? Ever seen their names in a boat catalog?

There is a high probability that you might have missed out on these boats.

Even though many brands still manufacture these boats, they have lost their popularity owing to several reasons. As a result, you might see other famous ships at the forefront of magazines, catalogs, websites, and window displays.

But the question remains, why did they lose popularity in the first place ? Why have people moved on to other boats for their use? Are trimarans not safe on large water bodies?

If you want to know about Tri Hull boats: Why they lost popularity, or other such questions, I have got you covered . You can find all the relevant information on these tri-hull boats in the following article.

Keep reading to learn more about their design, their uses, the cons, and even the future of these rapidly declining boats.

What is a Tri-Hull Boat?

Also called trimarans, many of these boats are manufactured as sailboats for both recreational and tournament use. However, the tri-hull design is quite popular with ferries and warships too. Or at least it used to be.

Over time, smart innovations modified the original double-outrigger model to improve the tri-hull boats’ speed, performance, and buoyancy.

Typically, tri-hull boats are counted under multi-hulls, along with catamarans and pontoon boats. Trimarans bear a distinct resemblance to V-bottom boats, except that these have a more pronounced shape and form large tunnels with their hulls.

Hence, sometimes you might even hear about these boats as tunnel boats too.

Overall, their unique design offers less contact with water and more buoyancy, which reduces drag on the boat. As a result, these boats are also quite fast compared to many other sailboats. Moreover, they offer a more expansive deck space and incredible stability to the riders.

Tri-Hull Boat Design

Now that you know what a tri-hull boat is, you need to learn more about its design to understand why it has lost its popularity in recent years.

To help you out, I have highlighted its unique design and how they affect the boat’s performance in the following section.

The boat features three hulls at the bottom, a main hull in the middle, and two amas or side hulls on either side of the main one.

Many tri-hulls have a subtle M-shaped bottom by using slightly smaller side hulls than the middle hull. These boats have a shape similar to a V-hull boat, just without the sharp edges.

On top of this, a few trimaran models might even have foldable amas. Usually, this feature is found in smaller boats to narrow their sides. As a result, you can convert your tri-hull into a mono-hull boat for easier storage and faster speed in choppy waters.

But the question still remains, how does this hull affect the performance of the boat?

Since the boat has wide, flat hulls, you get incredible stability on the boat. While most narrow boats wobble on the water when people are boarding, tri-hulls will stay true to their design. Moreover, you can even move around on the deck with ease and not risk making the boat tipsy.

Notably, a trimaran channels its stability from the amas and not from the middle huddle.

Buoyancy is another factor that a tri-hull boat excels in. The center hull offers almost 90% of the boat’s buoyancy, while the side hulls only keep the boat stable.

As a result, the long and narrow middle hull keeps the boat float on top of the water and even helps to push the boat to the plane much faster than other boats. Meanwhile, the amas barely touch the water, which further reduces the drag on the boat.

At high speeds, your boat will zoom across the water and reach planes much faster.

On the downside, its fantastic buoyancy can also become its downfall. Although these boats are ideal for speeding on lakes and rivers, they cannot handle rough waves on open seas.

With a three hull design, it is not surprising that you get a capacious deck on the top. This is one of the major reasons why these boats were quite popular in the 1960s as large ferries and warships.

Compared to other larger boats, tri-hulls have smaller cross-decks between the hulls. Hence, they also need less supporting structure in their design to offer stability on top of the deck. This also means that they can hold more weight and weigh much less than traditional mono-hulls.

Since trimarans come in both small sailboat size and large ferries, their engine depends mostly on their design. Most often, these boats feature an outboard motor with a high horsepower rating to reach top speeds.

With less physical contact of the boat with the water surface, you even get less drag on your boat. Therefore, your boat accelerates at a much faster rate to reach a high speed than other boats too.

However, their speed is mostly limited to planning on the water surface and not cutting the waves like the popular V-hull boats.

My Take on Tri-Hull Boats: Why They Lost Popularity

Apart from this, trimarans have been heavily altered and modified over the years to become multifunctional. This has resulted in the loss of the original tri-hull design and the replacement of these boats with a more modern boat version.

So much so that most of the tri-hull boat brands stopped new production way back in the 1980s. After their rise in popularity in the 1960s and 1970s, the boats are quickly becoming obsolete.

Without further due, let us check some of the most common complaints and cons of the tri-hull boats in the following section.

Even though trimarans offer superior buoyancy, their quality lasts only on calm water surfaces like lakes and rivers. When it comes to rough waves on the sea, these boats lose their value.

With a long and narrow center hull, these boats majorly float on top of the water. While this feature does not affect the quality of your ride on stable water conditions, the ride quickly becomes uncomfortable in rough waters.

To explain simply, the boat bobs on the water with every large wave on the sea. The resultant up-and-down motion became highly undesirable over the years, with people moving on to other more comfortable options.

Notably, this uncomfortable ride was more pronounced at higher speeds than slower ones.

Another downside to the tri-hull boats is their resultant wet ride in rough, choppy conditions. Since these boats do not cut the waves like the V-hulls, the strong waves slam against the sides, and front and splash water on top.

Tri-hull boats, with their design featuring three hulls, can potentially result in more water splash on riders compared to other boat designs, such as deep-V hulls. The flat-bottomed design of tri-hull boats may allow water to slap against the hulls, causing more spray and splash. This can be particularly noticeable when navigating through rough or choppy waters.

The placement and shape of the outer hulls in tri-hull boats can affect water deflection and spray patterns. Depending on the specific design and construction of the boat, some tri-hull models may have implemented features or modifications to minimize water spray and improve rider comfort.

However, it’s important to note that the amount of water splash experienced can also depend on factors such as boat speed, wave conditions, wind direction, and the design and shape of the individual boat model. Therefore, it’s recommended to test-drive a tri-hull boat or consult with experts familiar with the specific model to assess its water splash characteristics before making a purchase.

For this purpose, many manufacturers have modified the boats with foldable amas to deal with rougher conditions on seas. They can easily convert the traditional tri-hull into a mono-hull or V-shaped hull.

However, these modifications come at a loss of the original design.

Now that you know how trimarans are ideal for calm water surfaces mostly, their limitation on the choppy water surface is another primary reason for its loss in popularity.

Since water vehicles do not come cheap, people do not want to invest in a boat that is limited to lakes and rivers. If they are spending money, they want the option to take their ride to tumultuous seas and oceans and cruise with their friends and family.

Tri-hull boats, with their flat-bottomed design, may not perform as well in rough or choppy water conditions compared to other hull designs like deep-V hulls. The flat bottom can lead to a rougher ride and potentially more pounding or slamming in waves, affecting overall comfort and handling.

Tri-hull boats may have limitations when it comes to maneuverability, especially at higher speeds. The wider stance of the outer hulls can affect the boat’s ability to make sharp turns or navigate tight spaces compared to boats with narrower hull designs.

While tri-hull boats can be efficient at slower speeds and offer stability, they may have limitations in terms of top speed and fuel efficiency compared to other hull designs. The extra drag caused by the additional hulls can impact performance in terms of speed and fuel consumption.

Price is another factor that diverted people’s attention from the trimarans to other options. Who wants to pay a large sum for a boat that does not even offer a comfortable ride?

And believe me, these tri-hull boats cost a lot. With large cross-decks and extra hulls, the construction of a trimaran requires extra stainless steel or Aluminum. Hence, the cost of your boat just keeps piling up.

Besides this, the boat requires larger motors if you plan to use it in choppy waters. Heavy machinery almost doubles the cost of your final projects.

If you decide to invest in a trimaran with foldable amas and a massive center hull, even that will just end up racking up the cost.

When you can buy a much better boat with more luxury and a comfortable ride at the same cost, why would people invest in an ancient tri-hull model?

Better Alternatives

One of the significant reasons why tri-hulls lost their charm was the introduction of better industry alternatives. In the 1980s, V-hull boats and deck boats started gaining attention for their remarkable construction and optimum performance, even in the face of choppy water conditions.

With pontoon boats gaining popularity, people moved on to this luxury ride for all their boating needs, be it for water sports or a party cruise. Similarly, V-hulls proved to be a better alternative when it came to cutting waves at high speeds.

Now, you can only find the tri-hull design in limited sailboat models.

The Future of Tri-Hull Boats

As I mentioned previously, the tri-hull boats originated from Southeast Asian countries like the Philippines, where the community relies on watercraft for fishing and transportation of people and goods.

To this day, the ancient warship tri-hull design is used in their traditional fishing and sailboats for all their needs. However, with the increase in global greenhouse emissions, the use of fossil fuels in trimarans has posed a massive problem.

For this purpose, a marine engineer has designed a hybrid model that uses wave momentum to power the trimaran. Although the said ship has not finished construction, its success could open up many gates for innovations in tri-hull boats.

Tri-hull boats have experienced a decline in popularity over time due to several factors related to their design, price, options, and ride features. Here’s a summary of the key points:

Tri-hull boats feature three hulls, with two smaller outer hulls and a larger central hull. This design was popular in the past due to its stability and fuel efficiency. However, modern advancements in hull design and technology have led to the development of more efficient and versatile hull designs, such as deep-V or modified-V hulls.

Tri-hull boats were generally more affordable compared to other boat designs. However, as newer hull designs became more prevalent, the price difference between tri-hull boats and more advanced designs diminished, making other options more attractive to buyers.

Tri-hull boats often had limited options in terms of sizes, layouts, and features. Buyers seeking more customization or specific features may have opted for other boat designs that offered a wider range of options to suit their needs.

While tri-hull boats were known for their stability, they were not as well-regarded for their performance in rough or choppy waters. The flat-bottomed hull design of tri-hulls could result in a rougher ride compared to other hull designs, such as deep-V hulls, which provide better handling and performance in rough conditions.

As the boating industry evolved, consumer preferences shifted towards other boat designs that offered improved performance, comfort, versatility, and aesthetics. This change in consumer demand contributed to the decline in popularity of tri-hull boats.

It’s important to note that while tri-hull boats may have lost popularity overall, there may still be individuals who appreciate and enjoy their unique characteristics, stability, and fuel efficiency. The availability of tri-hull boats may vary depending on the region and local market preferences.

When considering a boat purchase, it’s recommended to assess your specific boating needs, preferences, and the intended use of the boat. Research different hull designs, test-drive various boat models, and consult with reputable boat dealers or experts to find the best option that meets your requirements.

Although tri-hull boats or trimarans have an incredible design that offers a fantastic experience on lakes and rivers, it does not handle choppy water conditions well. Not only does it provide an uncomfortable ride on open seas, but it also splashes water on the deck.

While all these reasons add up to its loss in popularity, the introduction of better alternative boats also played a major hand in its demise. Now, people opt for V-hull boats, pontoons, and even deck boats for all their boating needs.

However, you just need one invention to change the game completely.

What if a smart innovation in the next couple of years brings these ancient trimarans back into the industry? Keep in mind that the future is always unpredictable.
