J/111 - Grand Prix One-Design

Every now and then a new sailboat comes along that fulfills a real need in the market. The J/111 is a sleek, speedy, one-design 36 footer that is the ultimate day sailor, racer and weekender. J/111 is an easy-to-handle, comfortable sailboat that accelerates quickly, slices to windward at 7+ knots and hits double-digit speeds downwind. Performance to date in a wide variety of sailing conditions has been nothing short of remarkable.

Length Overall

Length at waterline, displacement.

Efficient, Comfortable Cockpit

Sailors spend more time in the cockpit than anywhere else, and this is where the J/111 shines. There's comfortable seating (with backrests) for six, easy movement afoot with floor mounted traveler and well positioned foot braces, an open transom for easy boarding, and large wheel so the driver can comfortably sit on the high or low side, on any point of sail, yet still see the telltales and waves. All principal controls are led aft and the driver can adjust the mainsheet, traveler and backstay from the helm position. An optional dodger is available to give the crew additional weather protection to extend the season.

Spacious Cruising Interior

The J/111 has all the essentials below for comfortable overnights and short cruises. The main cabin features an open layout with L-shaped galley, forward facing nav station, a wet locker and two full length settee berths with option for additional fold-up sea-berths.

Six can comfortably sit for dinner. Two spacious aft quarter berths are standard, as well as a private forward head and removable V-berth.

Less Crew = More Sailing

Sailboats that are easier to sail are sailed more often. It's that simple. A crew of two can fully manage the setting, jibing and dropping of the asymmetrical spinnaker where normally 5-6 are required to manage a conventional spinnaker. With a mainsail on slides, a furling jib and large wheel that gives you fingertip control, the J/111 can be off the dock and sailing in minutes.

This is a boat you can sail with friends and do it with confidence and ease. With the J/111, one's fun is not limited to coastal sailing. Whether double-handing to Mackinac, soloing to Bermuda or flying down the Solent with full crew, you can sail the J/111 with complete confidence and control.

J/11s – specially designed for short-handed sailing

• Matthew Sheahan
• March 16, 2017

Sharing the same hull as the popular J/111, this new boat is designed specifically for short-handed sailing. Matthew Sheahan tries her out

In 2015 the double-handed class trophy for the Rolex Fastnet Race went to Kelvin Rawlings and Stuart Childerley aboard the J/105 Jester . Neither had raced short-handed before that season, yet both said afterwards that this was one of the most memorable and satisfying races they had ever done.

And they weren’t alone. Throughout the fleet, whether they had won silverware or not, there were plenty of other sailors echoing the same thoughts; short-handed sailing is on a roll.

Rawlings and Childerley’s J/105 is a boat that is still considered to be one of the best for the job, despite the fact that the design is now well over 20 years old. This in itself is interesting given that J Boats in general have long had a reputation for being good to sail short-handed, thanks largely to the perceived simplicity of the asymmetric spinnaker, and yet have only now launched a boat specifically aimed at this type of sailing.

Several production builders such as Jeanneau and JPK have been tapping into the enthusiasm for short-handing with models such as the Sun Fast 3200 and 3600 as well as the JPK 1010 and 1080. But finally J Boats has joined in with the J/11S.

If this boat looks familiar it is because she is based on the J/111, a boat that has proved herself successful and potent in fully crewed racing. This new 36-footer shares the same hull, deck and, to a large extent, cockpit layout of the J/111, but that’s where the similarities end.

Tweaked for short-handing

The J/11S has been tweaked to make her an easier boat to sail short-handed and more competitive. As a result she has twin rudders connected to a single tiller, a slightly shorter rig and a smaller jib. To contribute towards the lack of bodies on the rail she has more internal ballast. She also has an alloy mast and boom.

The changes and tweaks have helped to bring her IRC handicap down from 1.096 to 1.050, a reduction that gets her under the upper rating limit for the Transquadra race, a popular transatlantic race for single and double-handed amateur sailors over 40. But J Boats believes that there is another key area in which the new model can score.

A slightly smaller jib than aboard the J/111 makes this boat that bit easier to handle and gets the IRC rating down

Unlike the beamy and angular Jeanneaus and JPKs, the J/11S is a more modest hull shape and as a result her builder believes she will prove to be a better all-rounder. Even from just an arbitrary glance, the J appears to have less wetted surface area aft, suggesting she will be less sticky in the light.

She’s a very seductive boat to sail, especially short-handed. Because she’s a more modest affair with a narrower beam than the other two she’s easy to get to grips with and without the wheel steering fitted in the J/111 she has a more open cockpit, which is easier to move about in.

Stretching forward to reach the jib sheets or pulling up a halyard is easy, nothing is too far out of reach and with the autopilot controls positioned close to the tiller it’s easy to press the ‘auto’ button and nip forward if you have to.

Not that you will want to let the autopilot steer for very long. She’s a lovely boat to sail and makes you wonder why wheel steering is so popular on most of the J Boat range. Why numb a great feel?

Balanced on the helm

She’s so light and responsive under sail you would be hard pressed to tell that she has twin rudders, she’s that balanced on the helm. Even when tacking and gybing she feels nimble. It’s only when you’re manoeuvring under engine that you start to feel her wider turning circle and the lack of prop wash on the rudder at low speeds. But these characteristics would be easy to live with when taken in the context of a boat that is a great deal of fun to sail.

But there is one amusing irony. Among the many reasons for J Boats’ continued success in Europe has been its asymmetric spinnaker configuration. Not only did this open up the possibilities for extended downhill sleighrides for club sailors, but the ease with which the kite could be handled, especially through gybes, made life easier for the crew.

Little wonder then that as the amateur short-handed scene started to gather pace, many saw J Boats as providing the perfect platform for both inshore and offshore double-handed racing.

And yet many of those who have been sailing two-up for some time and may have started with asymmetrics, believe that symmetric kites are easier to handle for a short-handed crew. They argue that, although they may be a little trickier through the gybe in some conditions, the ability to square back the pole provides a much bigger range of downwind angles to steer, which in turn increases the range of one sail, while also making it easier to keep the helm well balanced.

Some even argue that an end-for-end pole gybe on a kite that is flying all the way through the manoeuvre is easier, more stable and less risky than gybing an asymmetric. Hoists and drops are easier and less prone to a trawl with a symmetric kite, especially if you are recovering using the ‘letter box’ drop technique where the kite is gathered between the mainsail foot and the boom.

Symmetric kite and conventional pole

None of which has been lost on J Boats, master of asymmetric racer-cruisers, which had blanked off the retractable bowsprit moulding on the first J/11S in favour of a symmetric kite and conventional pole.

While I can see the logic, our test sail, performed two-up, suggested that we had a little more work to do on timing and technique! But whichever configuration you prefer, having the facility for both is a key advantage for this boat.

Below decks she’s a very straightforward affair with a pair of settee berths either side of the saloon table, a small galley to port and a dedicated navigation station to starboard. Further aft under the cockpit side decks are a pair of berths and the forecabin plays host to the heads and a sail locker. All of which reminds you how much space you have aboard a 36-footer when you take five people out of the equation.

The bottom line is that this is a boat that feels the right size for a short-handed crew – so much so that it seems a shame to spoil the side deck with bodies. At roughly the same length as the J/105 she also feels like a natural successor to the 680 built.

All she has to do now is head out there and prove it.

A return to a symmetric spinnaker pole may surprise some people, but the short-handed gurus claim that symmetric kites are easier and safer than asymmetrics

Not a standard fitting, but bound to be popular, this is the short fixed bowsprit for the Code 0. Note the slot for the bow roller and anchor chain

As you might expect, all controls are led aft, but the size and ergonomics of the cockpit mean there are no special arrangements. She just fits

J/11S is a 35 ′ 9 ″ / 10.9 m monohull sailboat designed by Alan Johnstone and built by J Boats and J Composites starting in 2016.

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)

Asymetric Area: 95m2/1023 sq.ft. Built by J/Composites in Les Sables dlonne, FRA
