J/70 is a 22 ′ 8 ″ / 6.9 m monohull sailboat designed by Alan Johnstone and built by J Boats starting in 2012.

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 Boat Reviews

Boat Review Date: October 2014 Author: Mike Brown Overview

There is a steadily growing number of sports boats on the Swan; sail craft around six metres long, essentially big racing dinghies with ballast keels. Terrific fun, but needing athletic dinghy-style crews to sail them well. And they are purely racing boats where most racing is done by keel boats that have other careers as cruisers. A new entrant to the scene goes some way to bridge the gap.

The J70 is the latest product of the builder that gave the world the extremely successful J24, so it has a respected pedigree. A shade under the seven metres suggested by its name, it combines 21 square metres of working sail area with a displacement of 794 kilos. 36 percent of that is ballast on the end of a 1.45m keel; these are figures that suggest an easily driven, stable and fast boat. A clue to the easily driven nature of the J70 was provided by the choice of auxiliary power: a 2.5hp Suzuki that was far from working hard when called into use.

WA’s first J70 had its maiden voyage on Fremantle Sailing Club’s opening day, with everything new to its crew. It was launched off a trailer, its lifting keel making this possible and simple. The routine of lowering and securing the keel, stepping the featherweight carbon fibre mast, tensioning the standing rigging and bending on the sails was quickly mastered. The routine is so straightforward it could probably be achieved in 20 minutes if money were at stake.

Winds on the day were flukey, with some respectable gusts. As soon as anything near ten knots cropped up the J70 was up and boogying, impersonating a lightweight dinghy. The crew for the day comprised four sizeable males, adding substantially to the displacement. The performance suggested adjusting crew numbers to wind strength would be a useful ploy.

It is illuminating to do a few sums on displacement and sail area with a lightweight vessel like this. We have all seen the pictures of seriously large racers with a dozen or more crew members sitting on the weather rail as organic ballast. Compare their vast sail area with the J70’s and see how much more affect a couple of 80 kilo people sitting on the J’s rail has. And the J70 has the shape and equipment to make this a natural and comfortable position.

But the J70 can have a life away from racing. Overseas, where this is a runaway big selling boat, it is a popular family or married couple craft for weekend fun with the occasional race. Loners can enjoy single handing in it. For the most social and laid back racing – twilights – the cockpit can accommodate eight or more as well as the esky.

The small fore cabin has V-berths long enough for use by humans, and weekending is very much an option. Overseas experience says a big use of the cabin is for children, sated with sailing, who can migrate there to play with electronic toys rather than asking if they are there yet.

The layout is uncomplicated allowing single handing; from one position the skipper can control the adjustable backstay, main and jib sheets. Extending the bowsprit and setting the asymmetric spinnaker, though, will call for few more hands. There is a pair of sheet winches that are likely only to get much use in stronger winds. These and all the other hardware are satisfyingly beefy items, well up to their jobs.

So far there is just the one J70 afloat in WA, but more were ordered at the Mandurah show. If overseas experience is any guide there should soon be enough here for one-design racing. The worldwide numbers grew so fast that less than 18 months after launching the International Sailing Federation approved the J70 as an ISAF class. The first world championship was held last month the entries capped at 120.

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.

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.

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.

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.

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.

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.

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.

Video Reviews of J/70

Just so you can enjoy the view of the J/70 sailboat in motion - this is a series of videos where both amateurs and aces of sailing regattas will demonstrate the boat's seaworthiness on camera.

Quick walkaround tour at 2020 Boot Dusseldorf:

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.

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/BOATS AUSTRALIA

J/Boats Australia are the importers and distrubutors of the quality performance range of J/BOATS for Australia, New Zealand and the Pacific.

J/70 SAILBOAT

SHIFT FROM PLEASURE TO ADRENALIN

Treat yourself to a genuine icon of one-design sailing! The J/70 is the perfect combination of an accessible design and unquestionable performance. 1,700 boats sailing in 30+ countries, with strong international and national class associations. Simple to own and easy-to-handle, J/70 can be sailed by all generations.

J/70 is all about FUN! It’s THE most widely distributed yacht in the world and for good reason.

HOIST THE SAILS AND ENJOY

With the J/70, you get to choose how you want to use her: a sporty pressure-free family escapade or a race on equal terms? Her lightweight design means you can quickly enjoy the delights of slipping along and her contained sail plan makes this bestseller totally safe and accessible.

JOIN THE AUSTRALIAN / INTERNATIONAL CLASS

Today the J/70 is considered to be the reference one design on a global scale! A record presence at every international event! The mastery of a precise and identical build process and an international organisation guarantee equal terms for every owner. Link to Australian J70 Class Association

GET USED TO HAVING FUN

A fun craft that is both simple and technical, capable of making 20 knots under spinnaker, this yacht is supported by sociable and united national classes. Her construction is dedicated to sailing enthusiasts, while her size means you can easily head out sailing whenever you fancy.

BENEFIT FROM CUTTING EDGE EQUIPMENT

The strengths of this yacht primarily rely on its latest generation equipment, with a carbon rig and top of the range construction technology, which make it lightweight and stiff with great longevity.

SIMPLIFY YOUR LIFE

When the weather is fine, why wait to make the most of it? A small sportsboat measuring 7m, the J/70 is light on the helm, easy to transport and simple to launch and rig. Her keel is retractable, meaning she’s easy to tow with the reduced height on the trailer.

BE PART OF A PERFECT SPORTS ORGANISATION

Its small manufacturing tolerances are a guarantee of sporting equity for all. The network of owner classes offers events of a regional and international scope in each country.

DEMAND RELIABILITY

Even when used intensively, the build quality of the J/70 guarantees unrivalled resilience and solidity, which translates as a high resale value. Thanks to a genuine ‘racer’ culture, a constant eye for detail, highly selective materials and strict production control, this boat is bordering on perfection in operating terms.

MAKE THE MOST OF THE ERGONOMIC COCKPIT AND CABIN

The cockpit is clean, well designed, uncluttered and easy to move around. With her small cabin, you’re protected from bad weather and also all the equipment for the boat and the team can be easily stowed and transported inside. The outboard engine can be fully stowed down below while sailing.

GET INTO RACING

The characteristics of the J/70 make her accessible to all. She is perfectly suited to crews of all ages and genders, with light sheet loadings and great cockpit design, layout and equipment. The strict rules on ‘no hiking’ mean that those who don’t take part in intensive training can still easily compete against more honed crews.

International and Australian Class Associations

The presence of J 70 classes in over 30 countries around the world means that a very dynamic one design race circuit is prevalent.

Respecting the Class

J Composites devote a great deal of attention to respecting the class measurement. With over 10,000 sportsboats built in over 30 years, the J Composites yard has fully mastered manufacturing tolerance.

One design requires specific equipment in terms of deck hardware and sail area, which translates as an interesting racing programme, whilst limiting the expense of the arms race.

The close competition during races is evidence of the precise construction for every craft. As such thrills are guaranteed around the course and during the mark roundings!

Retractable Keel

Transporting the J/70 is made possible by its retractable keel. This enables the boat to sit lower on its trailer making it easier to transport.

Deck Stepped Mast

The J/70 boasts a deck-stepped carbon mast, which means the process of stepping the mast is considerably easier as it requires just two people.

Lifting your J/70 is hassle-free thanks to its central sling points, meaning the operation can be completed in a matter of minutes.

Once the boat is on her trailer, she can be easily towed by any family car or SUV. The J/70 can also be ramp launched.

The materials for the sandwich construction are selected with precision so as to achieve the best possible combination of lightness/solidity on the market.

The retractable keel comprises a 316L stainless steel structure and a lead bulb. The whole thing is encapsulated in a molded structural composites form.

The J/70 is delivered with a carbon mast boom and bowsprit, benefiting its handling, and making it responsive and stiff. Furthermore, it can be easily stepped and rigged by 2 persons.

The carbon parts of the J/70 are made in an autoclave to guarantee unrivalled longevity.
