The J/111 arrived in 2010 as a statement of intent: Alan Johnstone distilled everything the Johnstone family had learned from the celebrated J/105 into a faster, lighter, and more immediately rewarding 36footer. The premise was disarmingly straightforward — a boat that he and the rest of the J/Boats crew would genuinely want to sail — and the result was a onedesign that has earned its reputation on both the racecourse and the daysail roster. At just over 36 feet on deck and a shade under 33 feet on the waterline, with a slim 10foot10inch beam and a vacuuminfused balsacore hull, the J/111 sits in a persuasive middle ground: more purposeful than a cruiserracer, more livable than a pure IRC weapon.

Design and Construction

The J/111 hull is vacuum infused with E-glass and vinylester over a balsa core, a construction method that keeps displacement to roughly 9,300 pounds — approximately 2,000 pounds less than the J/109 it succeeded in the J/Boats lineup. The deck is hand-laid, and the vertical stem and near-vertical stern maximize sailing length while giving the boat its distinctly modern, purposeful profile. Belowdecks, a stainless steel fin carries a lead bulb keel drawing 7 feet 2 inches, providing the righting moment necessary to carry 751 square feet of working sail. The fin is set into a hull recess with a stainless flange, and its leading edge incorporates a kelp cutter — a practical detail for inshore racing. Steering is handled by an E-glass spade rudder with a carbon post, connected to the helm through chain and wire rather than rope, routed through Edson Articu-lock sheaves with needle bearings. The result is communication rather than mere control: two fingers on the leather-wrapped 60-inch Edson destroyer wheel are enough to feel and direct the boat.

Rig and Sail Plan

The Hall Spars autoclaved carbon fiber mast — built with nanotube technology to increase stiffness while keeping weight low — is supported by Nitronic discontinuous rod standing rigging and a double set of tapered aluminum spreaders. A non-overlapping headsail keeps tacking effortless; the low-profile Facnor FlatDeck furling drum uses flat webbing rather than conventional furling line, reducing the drum's footprint and improving lead angles. All control lines — halyards, reefing, furler, and retractable bowsprit — are led aft internally to the cockpit, so nobody need leave the helm to deploy the sprit or adjust sail. Two Harken Radial self-tailing winches, a two-speed traveler, and an adjustable jib lead system handle the working sail load. Downwind, the extended bowsprit carries an asymmetric spinnaker rated at 1,410 to 1,798 square feet depending on the source, turning the J/111 into a planing machine in a matter of seconds. Jeff Johnstone described the philosophy plainly: a sailboat that is easier to sail gets sailed more often, and the rig delivers on that promise without sacrificing performance.

On the Water

On the racecourse, the J/111's narrow beam and deep, high-aspect rudder make it easy to control even when heeled hard. Tacking in steep chop off Newport Neck was described as effortless during early sea trials, with precision helm control throughout and no moment of doubt about completing the maneuver. In the puffs, the boat accelerates like flicking a switch — a response born of light displacement, a well-balanced sailplan, and the low center of gravity the bulb keel provides. Off the wind the transformation is dramatic: once the bowsprit is deployed and the asymmetric drawing, the boat lunges onto a plane with a speed increase that leaves little doubt about what the J/111 was built to do. Upwind, the long waterline and narrow sections let the boat point impressively high while maintaining boat speed in the mid-to-upper single digits in moderate breeze. Strategically placed foot cleats and a well-proportioned helm position make steering the boat a genuine pleasure for an extended watch.

Accommodations

The interior is deliberately lean, which is both its limitation and its virtue. Six feet of standing headroom in the main cabin is generous for a boat of this type, and the layout provides four serviceable sea berths for coastal passages and offshore racing. Two quarterberths aft each measure 6 feet 9 inches; the main cabin settee runs 6 feet 4 inches and doubles as a sleeping berth. If an owner opts in, the forward cabin can be fitted with a V-berth; otherwise it functions as a sail locker — a telling indication of the J/111's priorities. The galley to port carries a two-basin sink, a top-opening refrigerated icebox, and a freshwater foot pump. To starboard, a sit-down navigation station centers on a wooden desk with a hinged lid for chart storage. The head is basic, private, and equipped with a vanity. Interior finish is described as simple and elegant, far from Spartan — meaningfully better than the J/105 it evolved from, even if it remains unambiguously a performance boat's cabin rather than a cruising yacht's. Holding tank and a 15-gallon fuel tank are fitted as standard, enabling entry into offshore events that require them.

Engine and Systems

The engine — a three-cylinder, four-stroke unit with saildrive — lives beneath the companionway ladder in a molded, noise-insulated box. Access is straightforward: two clips release the top of the ladder, the bottom legs lift out of their deck sockets, and four stainless slide bolts unlock the box. Three sides of the engine are then accessible for checking fluids and making repairs. Power is transmitted through a 16-inch Flex-O-Fold geared folding propeller, which folds cleanly under sail to minimize drag. The Harken winches are designed from the outset to accept electric conversion with minimal modification — no rebuild or replacement required — a thoughtful provision for owners who want to add electric power later without a major refit. Some owners have also added autopilots, and the clean cockpit layout accommodates these additions without conflict.

The Verdict

The J/111 succeeds because it refuses to hedge. It is a sprit-boat racer that happens to be comfortable enough for a weekend aboard, not a weekender with racing ambitions grafted on. The hull construction is genuinely stiff and light, the rig is sophisticated but uncomplicated, and the cockpit is large enough for a full racing crew or an easy afternoon with friends. Its 7-foot-2-inch draft and performance-oriented interior mean it is not suited to shallow-water cruising or extended passages, but within its intended scope — one-design and IRC club racing, weekend coastal sailing, and pure sailing enjoyment — it delivers at a level few production boats at this length can match.

Pros

  • Vacuum-infused balsa-core hull keeps displacement well below comparable 36-footers
  • All control lines led aft; bowsprit deploys from the cockpit without sending crew forward
  • Carbon mast with nanotube-enhanced stiffness and rod rigging reduce weight aloft
  • Bulb keel provides strong initial stability and righting moment for a narrow-beamed hull
  • Harken winches designed for future electric conversion without modification
  • Expansive cockpit works equally well for racing crew and daysailing guests
  • Engine access is genuinely simple and requires no tools to open

Cons

  • 7-foot-2-inch draft limits harbors and anchorages
  • Forward cabin is a sail locker by default; V-berth is an optional fit-out
  • Interior appointments prioritize weight savings over comfort on extended passages
  • Anchor locker present but bow pulpit carries no hardware for deployment — anchor handling requires planning
  • Not designed for bluewater or extended offshore cruising
