Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

• SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
• D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

• D: Displacement of the boat in pounds.
• LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

• D: Displacement of the boat in pounds
• LOA: Length overall in feet
• Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

Spinnaker (asym.) area: 491 sq.ft./45 m² More than 1100 delivered as of 2016.

J/70 – World’s Fastest Growing One Design, Trailerable Speedster!

Easier to trailer, rig and ramp launch. The J/70 Speedster (22.75 feet) is J/Boats’ first fully ramp-launchable, keelboat – designed to fulfill a growing need for an easy-to-own, high performance one-design that is exciting to sail, stable enough for the entire family, easy to tow behind the family vehicle, to rig in the parking lot, ramp launch and sail.  Plus, J/70 is built to last.

In less than 48 months the J/70 worldwide fleet is over 1,300 boats strong, attracting some of the most talented sailors in the world and helping to spark growth of numerous sailing leagues across Europe. J/70 is replacing tired old keelboat fleets at a number of sailing clubs and helping to reinvigorate membership by attracting younger sailors into the ranks.  There are fleet discussions underway now around the world both for new leagues and for established clubs.  The Sailing World Overall Boat of the Year J/70 has taken the world by storm and future growth for this fantastic boat looks very bright, indeed!  These days it is safe to say  there is some J/70 event happening on almost any given weekend somewhere around the world!

Key J/70 Features.

• Large comfortable cockpit with open transom.
• Deck-stepped lightweight carbon mast for easy rigging & stepping.
• Inexpensive three sail inventory with masthead A-Sail.
• Vertical lifting keel.
• Small cabin for storage and personal privacy.
• Easy to trailer to regattas, ramp launch and store at home for winter.
• Only 1,750 lbs & low road height so most 6 cyl vehicles can easily tow.
• Fits inside most standard garage doors!

More comfortable to sail on deck. The 11′ long cockpit and moderate height boom in the J/70 allow easy crew movement across the cockpit while tacking and jibing. For sitting and hiking comfort, mid-height padded backrests/lifelines run cockpit length, large cockpit floor mounted toe-rails for secure foot bracing and comfortable seat height and ergonomics makes J/70 one of the most comfortable small keelboats to helm.  No need for hiking straps to keep you in the boat. Plus there are strict class limits on how to hike to make the boat less physical to sail.

Easy for the entire family to join in! With mandatory on-board jib/spinnaker sheet winches, a feather light responsive helm and confidence building stability, you can enjoy sailing with friends and family more often.  Kids or seniors will feel as comfortable and in control steering or trimming sails, whether for daysailing or evening sunset races, the J/70 will be both exciting and forgiving.  When you are ready to take it to the next competitive level, the competition at national events won’t disappoint.

On-board privacy, protection, storage & auxiliary power The small cabin below is a bonus in any small keelboat, and the J/70 cabin is just large enough to provide weather & sun protection, a place to nap and/or for personal privacy… essential to keeping the whole crew happy if spending a day on the water.

The J/70 one-design class rules provide for a 2.5 hp outboard engine (gas or electric). This means one can sail further away from homeport without worrying about paddling home or hailing for a tow. Race Committees can start races on time and finish them later in the day without having to arrange tow boats.

J/BOAT’S FIRST RAMP-LAUNCHABLE KEELBOAT DESIGN                             

This new 22.75 foot speedster is designed to fulfill the growing need for an easy-to-tow, high performance, one-design that is exciting to sail, yet stable enough for the family. She is built to last under the watchful eye of J/Boats and the Rhode Island manufacturer CCF Composites. Class development is accelerating dramatically around the world. In the U.S. alone, there are over a dozen J/70 fleets that have formed already with nearly twice that amount in the formative process across America.

In 2012 SAIL Magazine’s panel of sailing experts reviewed a large cross-section of “performance” sailboats in the 30-foot and under size range. After a thorough evaluation of all the boats, the SAIL Best Boat expert panel chose the J/70 as the “Best Boat” in the “Performance Category”.  The J/70 also is Sailing World’s Boat of the Year Winner and has now reached ISAF (International Sailing Federation) status.

Here are the included features:

            Large comfortable cockpit with open transom (Harken winches & deck hardware & 11” SS lifelines w/comfort pads)

            Deck stepped carbon mast with single spreaders and carbon boom.

            3 Sail inventory including a masthead asymmetrical spinnaker (below-deck jib furling)

            Vertical lifting keel (4.75’ with kelp cutter that reaches down about 80%)  and it works!!

            Fixed motor mount (accommodates short shaft outboard)

            Cabin for storage and personal privacy (V-berth)

            Trailerability with easy ramp launching and retrieving

2022 Pricing is currently at $49,900 for the boat and $4,995 for a Triad trailer. Sails are additional (see more information later) plus a $100 factory set up fee prior to shipping.  Prices are subject to change.

Next available Hull is October of 2022.

To order a boat, a modest reservation deposit gets a hull assigned to you with a molding deposit due 3 weeks prior to molding. The balance is due upon completion. There are only two production line options (bow & stern hull guards $350 total), but after- market options are available through HOOPER’S which include cushions, covers or trailer modifications (detailed here later). At least 4 J/70’s without trailers can be shipped on one truckload. Three boats with trailers can ship on one truck load.

Any individual or group interested in ordering one or more boats should please contact Hooper’s Yachts. Special pricing may be available.

Performance and Sails:   In mid-April, 2012 on the water sail sessions were completed and it is no surprise that the J/70 can fly. The top speed realized was 16.2 kts with another boat hitting 15.8 kts. The most talked about characteristics was how quickly the J/70 accelerated both upwind and downwind. It was reported that she sails upwind, steering and tracking like a boat several feet longer - very easily. Stability was also realized as it was no surprise that the J/70 handled conditions very well. In Europe the spectacular wipe outs were from the European competition and the J/70 easily handled them all in the medium to heavy air. ‘Blew them away. In the 2013 French off shore race, the J/70 hit 20 knots.

In 2013 they set the J/70 NA Championship at a 90-boat entry, but the quota was hit in only 28 hours. So it was raised to 120 boats for the 2014 NA’s and that sold out in hours too. The J/70 phenomenon is crazy. Over 600 hulls sold in just over 2 years after first launch. In today’s economy, that’s remarkable. Some say it is not high performance enough. It is clearly fast, but not so amped-up that only really good or young sailors can manage it. We have heard that it is too easy to sail – too simple, but that translates into more participation – a design that is more inclusive. You can get into the sport boat game and develop as you go. She’s fast, but not intimidating, fun for various ages and abilities, affordable and offers good racing or day sailing everywhere you go.

The one-designed dimensions and specifications for the 3-sail class inventory have been finalized. Both North Sails and Quantum Sails helped with the process with collective input. The class rules are now available for owners. Anyone interested in receiving more information on sails can request them from us at any time.

2021: Quantum  Class Sail prices are $7,000 and  North Sails  is $7,599 and  Doyle Sails  is $7,300. ( Royalty and options might not be incl ) (All prices subject to change).  For fleet or institutional boat orders, special reduced pricing  might  be offered. Sales tax and freight are not included.  Sails should be ordered at the time the boat is ordered and a 50% deposit will be requested at that time. The assigned hull number will be sent to the sail maker of your choice and spinnaker colors will be selected.  Clew blocks may be additional.  The balance will be due when the sails are completed.

What is the anticipated crew weight limit?  One-design rules say that the crew should consist of 3 or 4 people.

Any class limits expected on hiking?   The J/70 has 11” high, stainless safety lines with comfort pads around the cockpit which are designed for comfortable seating, facing either inboard or outboard. This suits the boat well for club team-racing/match-racing events which tend to prefer inboard seating vs. one-design/recreational sailing where both are popular. As there is no bow pulpit, class rules require crew on deck to stay aft of the mast except for temporary sail handling needs which should be minimal with a roller furling headsail and retractable sprit for the asymmetrical which can be launched from the cockpit. Not more than two crew may have their legs outboard of the sheerline. When tacking or gybing, crew shall not hang, push or pull on the shrouds, mast, cockpit safety lines, stanchions or any other item to promote the maneuver. No roll tacking.

What is the expected PHRF Rating?   It’s too early to tell until the boat sails head to head against some PHRF benchmark boats in various conditions – something that is underway now.  The one-design sail plan is nicely powered up, so there is no reason to consider non-class sails, which also helps keep your cost down.

After market Options:

Several suppliers have stepped forward with offers to provide aftermarket accessories such as canvas products, cushions and outboards. J/Boats is encouraging this open market approach as apposed to exclusivity which tends to push pricing up. So, they are dealing with reputable suppliers that dealers can work with. But, these options are not essential.  Here are some of the many items that will be available through Hooper’s Yachts:

V-Berth Cushions                                                                                                                  

            Line Bags

            Mainsail Covers

            Furling Jib Luff Covers

            Electronics, compass, Windex, etc.

            Outboard Motor (Torqueedo Electric 1003 $1,999) We are also Nissan/Tohatsu dealers

            Bottom Paint

            Ground tackle, fenders, dock lines, etc.

            Running & Cabin lights (portable or permanent)

COMMENTS FROM J/70 SAILORS:

My impressions, as crew, of the J70 are positive. Like most J boats she is well mannered and comfortable. She does not appear to have any bad habits or quirks. Overall it was a really fun weekend with two great days on the water. I got the impression everyone involved was psyched to be there and looking forward to more racing on the J/70. There was plenty of talk of races in FL this winter and growing of fleets in the Great Lakes, the Northeast and the Mid-Atlantic in the spring. –Greg Lanese after sailing the Fall Brawl First J/70 OD completion in Annapolis in heavy winds

The boat definitely does not feel and sail like a sport boat. It sails like a keel boat and that is good. - Rich Stearns

The comment after the first J/70 sail from one of our local buyers: “  the boat is a Ferrari, just wonderful. Smooth, fast, stiff”.

The never-fading star of j/boats.

The year when a new star was born is 2012. But to this day, J/70 remains the brightest in the constellation J/Boats, even though this 7-meter keel sailboat is the smallest in the history of the shipyard.

After the first tours, tests and reviews in the US it was extremely well received. The boat was shown to European customers in December at a yacht show in Paris. By this time, the first regattas with the participation of the new class had already taken place in the New World, which, without administrative levers and lobbies, gathered more than 20 crews.

At the very first yacht exhibition in Düsseldorf following these events, the sailing boat J/70 was awarded with the title of European Yacht of the Year 2012/2013 in the Special Yacht nomination, besides the boat collected nominations 2013 Boat of the Year in the US and UK.

At the same time, the traditional Key West Regatta was held, in which 40 crews chose the J/70, and this is despite the fact that the first hull was sold only 6 months before that. The new class enters the European racing calendar just as quickly, starting with the Primo Cup Monaco regatta. The shipyard reported that it had received about 400 orders from 18 countries. No model of a 7-meter keel racing yacht has yet demonstrated such growth in popularity.

J/70 by topRik Team

What kind of boat is this and what is the cause of such a high demand? Based on their own experience of participating in the J/70 regattas, the experts of the topRik team tried to answer these questions in as much detail as possible.

All Things Are Known by Comparison

Due to hereditary proximity, the new boat is best compared with its predecessor J/80 and closest competitors Melges 20/24 and SB20.

Compared to the J/80, the new boat is almost twice as light, while the sail area has not significantly decreased. It is easy to transport, it does not require special equipment for launching and installation of the mast is not needed (the complete carbon mast weighs less than 25 kg). Crew from 3 to 5 people, no weight limit (according to class rules). The J/70 enters planing much earlier than its predecessor, easier to manage too.

The ban on the use of foil sails and more than one set per year keeps the class open to everyone. The popularity of the J/80 and J/24 class in the world has attracted strong world-famous riders to the new class!

The high cost of ownership and excessive "acrobatic" Melges 24 did not provide much development to the class. For 10 years, the class could not catch up with the J/80 in terms of mass. The appearance of the M20 on the market should have changed the ratio, but this did not happen. It was J/70 that immediately occupied a niche between the M24 and M20, being just as fast and dynamic, but at the same time being cheaper and easier to set up and manage. In addition, it is more accessible to beginners, as it does not require them to be athletes.

Comparing the new class with the SB20, it should be noted that the SB20 itself is a very successful boat. It is as dynamic, fast, easy to handle and transport as the J/70. But the T-shaped keel collects all the nets and debris in coastal areas and it is also more difficult to use in an incomplete crew, for family outings and for training young people. In addition, in terms of build quality and hull strength, the SB20 is significantly inferior to J/Boats products.

Features of the Design and Sailing Equipment

The J/70 is the first lifting keel racer from J/Boats, which has ushered in a new era not only in NYYC but in organized sailing in general.

The carbon fiber mast is very easy to mount. A simple sail plan includes a square-topped mainsail, a roller staysail and a gennaker on a retractable bowsprit.

If you wish, and for insurance in case of little experience in sailing, you can install an outboard engine with a power of 2.5 HP on the transom.

The yacht is easy to attach to and it is just as easy to launch from the ramp of the car. For such meager dimensions, she has a surprisingly large cockpit, where the entire onboard life of the regatta crew takes place.

The Crew of the Yacht for the Regatta and Their Tasks

You already know that the J/70 is in most cases purchased for racing and is a team yacht. The composition of her crew is usually limited to 5 yachtsmen (maximum) – and if this is a training vessel, then add an instructor.

As a rule, the roles on J/70 are distributed as follows:

• forward - controls the setting and cleaning of the gennaker, is in the cockpit along with the rest of the team;
• trimmers – they work with staysail and mainsail;
• helmsman - controls the yacht with the help of a tiller.

At amateur regattas, like those that the topRik team holds every Sunday, a professional skipper-instructor manages the yacht, he also distributes roles between crew members and gives commands to each of them.

In professional teams, the yachtsman working with the mainsail plays the role of tactician. In amateur teams or a team of beginners, the skipper is responsible for tactics, he is also an instructor.

Don’t Expect Luxury

Yes, this sailboat does not promise a luxurious life on board. Here, everything is subject to speed and maneuverability, which means minimizing weight, including at the expense of furniture. For yachtsmen who prefer active yachting, adrenaline and physical activity, such a niche in the cabin is enough to equip a sleeping place for two.

The J/70 is a challenge for experienced sailors, but at the same time, the yacht remains interesting for less ambitious yachtsmen who prefer an active holiday with friends or family, without the need to set speed records.

J/70 101 – Tips From the topRik Crew

Participants of J/70 class regattas will be interested in the principle of crew selection. The topRik team consists of 4 people weighing from 79-81 kg each, with a total weight of 320-322 kg. Exceeding this weight, in our opinion, can lead to unnecessary resistance.

The yacht weighs 794 kg, so it is easily towed using the trailer of an ordinary car. After the crew learns how to set up the mast, preparations for launching will take less than an hour.

If your trailer is not designed for a lowered keel, it is usually raised before the yacht is lifted out of the water. On the road, we recommend securing the sailboat with softwood wedges. This is necessary to prevent the keel from rocking and to prevent damage.

The J/70 class is limited to three sails: mainsail, staysail and spinnaker (or gennaker). In most cases, you can further limit your use of sails to just one of them. But you can take advantage of the developments of various companies producing sails, which for this class have developed variants of the staysail and mainsails that are suitable for different weather conditions.

Good News for You

We can happily announce that the racing sailboat J/70 completely won the hearts of the topRik team in full force, including the skipper. Therefore, we decided that everyone who is devoted to sails and the wind in their hair should experience these sensations.

Every Sunday, supported by SimpleSail and Porto Montenegro, you have the opportunity, together with our yachtsmen, to participate in races on J/70 yachts. We set the distance, go through 4-6 starts, and at the end - a small barbecue party.

It is not necessary to have experience in regattas - experienced yachtsmen of the topRik team will be in your crew. They will help you to join this amazing sport in the Bay of Kotor (Montenegro). You can see fragments of such Sunday races with topRik in the photos below.

Advantages of J/70

The main advantage of this sail racer is the thrill during each race. After all, the distances separating the leader of the regatta from subsequent boats are minimal if we are talking about professionals. This suggests that the design and handling of each boat is similar to the others , so that the skill of yachtsmen is clearly demonstrated during the competition.

The simplicity of the rig combined with the tiller ensures not only easy and intuitive handling, but also makes it easy for beginners to learn quickly.

The quality of materials ensures the durability and safety of the yacht:

• precisely selected composite materials for the body (sandwich based on infusion composite construction);
• stainless steel for retractable keel;
• bulb made of lead;
• carbon mast and other autoclaved carbon alloy parts.

There is nothing superfluous here - you can fully devote yourself to sailing, since the weight of the boat and the minimum wetting area allow you to develop high speed with a quick switch to planing and excellent maneuverability.

Such minimization in dimensions, sailing equipment and luxury elements was reflected in the decreased price tag, which, undoubtedly, is another important advantage of the J/70.

Reviews of J/70 from Professionals

Traditionally, we provide the opinions on the J/70 sailing racer from yachtsmen-journalists working for professional yachting magazines and popular websites dedicated to yachting, boats and naval architecture.

First, we decided to post excerpts from an interview with Peter Rendle, a yachtsman and correspondent from Sail-World, in which he talks to Ray Entwistle, the Australian distributor for J/Boats.

Here's Ray's response to a question about the history of the J/70. This sailboat has been designed to meet the demand for a boat that is easy to handle, safe for family sailing, yet with high performance. At the same time, it was required that the yacht could be easily towed, mounted effortlessly on the frame and launched from it into the water. These tasks were assigned to Al Johnstone, naval architect and designer for J/Boats. He coped with the task perfectly, considering that over 20 years her popularity has not only not decreased, but continues to grow. She repeats the glorious 40-year history of the J/24, which is still a hugely popular one-design racing yacht. The J/70 is the next generation and has already played its part in the single-design racing classes.

He noted the J/70's popularity with sailors of all ages, from teenagers to 70-year-olds, families, and single-class yacht racing enthusiasts.

The splendid design is complemented by the latest generation of carbon rigging and advanced construction techniques, making the yacht extremely light and durable with sufficient rigidity.

The seaworthiness of the J/70 makes it suitable for youth and women's teams. The strict rules of the J/70 regatta prohibit walking, which means that even less experienced crews can compete on equal terms with those who train intensively. The J/70 is full of surprises.

Adam was part of the crew that tested the J/70 to determine the Best Boats 2013 winners.

He began his review with an intriguing statement that could indicate a negative assessment: the author announced that he was disappointed with testing a high-octane sports boat in a drifter. But it turns out that this in no way about the J/70.

The crew went sailing in sustained winds of 20 knots, with gusts in excess of 25 knots, with strong rip currents off Bristol, Rhode Island. On the way towards Popasquash Point, the boat proved to be nimble and manageable. The sailboat accelerated quickly in the gusts, and the light steering was maintained even when it dug into waves to leeward.

Even when they overshot the tack and the boat capsized momentarily, the crew didn't feel it was out of control. Here the ballasted keel and the large tiller rudder placed on the transom played their role.

Thanks to the spacious cockpit, which quickly cleared the water and a fairly high boom, moving from side to side was easy, which could not be imagined on the famous J/24.

Then J/Boats company’s president Jeff Johnstone decided to see if the sailboat could take off with just a mainsail and staysail. And was the crew delightedly admiring the foam trail, similar to the one left by Volvo Ocean Race 70 at high speed. But what impressed Adam more was how easily the team did it. At the same time, the skipper was not at all worried, because he received effective feedback to control the sails, but only tried to make the yacht move even faster.

Adam devoted a significant part of the review to describing the design, equipment of the yacht and their manufacturers. He noted that the efficiency of the boat's rudders and the shape of the hull, with its sharp bow and flat planing sections, are complemented by a carbon fiber mast with steps on the deck, a boom and a retractable sprit, made by Southern Spars.

Deck equipment on the test boat was provided by Harken, with rigging from Ronstan. You can rely on Dyneema's poles and lifelines to brace your back against when your legs are inward. On the keel there is a seaweed cutter. For safety, a solid side is equipped on the bow deck. The quality of construction is excellent throughout.

Dave describes his impressions of the J/70 while testing a sailboat for the 2013 Boat of the Year nominations.

He reports that the judges noted the versatility of the boat in the field of application: both single-design and club racing. Among racing yachts, this is not a very common occurrence. Among the best qualities were noted: a quick set of speeds, stability, ramp launch and, interestingly, the rapid development of the class just a year after the world premiere.

One of the testers, judge Greg Stewart, noted that the boat sailed really well in wind speeds of 10 to 15 knots. There was a slight feel from the helm both when driving upwind and downwind. It was immediately noticeable that the yacht was strong and stable - she sailed well on the waves, and with the kite up the crew got the angles they needed.

The stability of the J/70 is a key feature that the judges singled out immediately after ten miles. As Jeff Johnstone said at the jury briefing, stability was a fundamental concern for the developers. He added that there were originally two completely different designs: a recreational sports boat and a club coach. As a result, the choice settled on a sportier option that could be easily modified for sailing sport programs.

The location of the winch caused a discussion between the shipyard representatives and judge Tom Rich. Even though the 3.3-meter cockpit allows three adults to move freely, Tom reported that when he chose the most comfortable position to steer the boat - forward of the traveler, he was pressed against the winch.

Alan Johnstone joked that everyone who used the boat would like to get rid of the winches. But they will have to be tolerated, because they will be needed when driving in the wind, as the helmsman changes position.

Judging by the fact that the J/70 received the title of Boat of the Year 2013, the rest of the judges considered this moment insignificant.

Mike describes his impression of the J/70 he received on Fremantle Sailing Club's opening day when WA's first J/70 made its maiden voyage.

The J/70 sailboat has a respected pedigree and is the product of a shipyard that has already given us the very successful J/24. The length of the new racer under seven meters combines 21 m² of sail area with a displacement of 794 kg - 36% of this weight is ballast at the end of the 1.5-meter keel. All this math results in an easily manageable, productive and stable boat. The 2.5 HP auxiliary power unit makes this operation even easier.

The J/70 was launched from a trailer, made possible by the lifting keel. The crew quickly mastered the whole procedure: lowering and securing the keel, raising the carbon mast, tensioning the standing rigging and tilting the sails. After some practice, it turned out to be so easy that the team could complete the preparation in 20 minutes.

Light winds with little gusts and a daytime crew of 4 big men were the test conditions that day. When the speed approached ten knots, the sailboat rose and hummed, depicting a light boat. The performance can always be improved by adjusting the crew size depending on the strength of the wind.

The J/70 will also enjoy life outside of racing. In many parts of the world, this thriving boat has become a popular yacht for families, couples or a small company for fun without speeding up. Experienced loners can enjoy playing the lone skipper. For recreational, social and casual racing, the cockpit can accommodate eight or more people.

In a small forward cabin with a V-shaped berth, children can be accommodated if they are present on the deck, and if not, two adults can lie down freely there.

The sailing layout is simple, you can control it with one hand: an experienced skipper can control the backstay, mainsheet and staysail from one position. But to extend the bowsprit and set up an asymmetric spinnaker, you need a couple more hands. A pair of winches will be indispensable in strong winds.

As you can see from our review and feedback from famous J/70 regatta participants, this is a very fast, maneuverable and safe sailing yacht, ideal for speed and tacking competitions. It is no coincidence that more than 3,000 cases have been sold to date.

But do not think that all of them were purchased for the crews of the regatta. The boat is also in demand among those families and friendly companies who do not strive to break speed records under sail, but love adrenaline and wind themselves. And J/70 is one of the best options, combining all these preferences.

The cost of the yacht allows her to become in demand among those who dream of their first boat. This is a great opportunity to immediately learn all the best that active sailing has to offer.
