The J40, a performance cruising boat, was designed by Rod Johnstone and built in the USA by Tillotson-Pearson.
The J40 was designed by Rod Johnstone and built by J Boats between 1984 and 1993. It was the first bluewater offshore cruising boat built by J Boats, and it has a loyal following of owners who appreciate its performance, comfort and quality.
The J40 is a sloop-rigged boat with a fin keel and a spade rudder. The sail area is 765 square feet, which gives it a sail area to displacement ratio of 18. The boat is powered by a 43 hp diesel engine.
The J40 has a sleek and elegant hull shape that is optimized for speed and stability. The boat can handle a variety of wind and sea conditions, and it has a reputation for being fast, responsive and easy to sail . The J40 has also proven itself in offshore racing, winning several awards and trophies under the ORR and PHRF handicap systems.
The J40 can accommodate up to six people in two separate cabins and the main saloon. The forward cabin has a V-berth with storage underneath, a hanging locker and a private head with shower. The aft cabin has a double berth, a hanging locker and access to the second head with shower. The main saloon has a U-shaped dinette to port that can convert into a double berth, and a settee to starboard that can serve as a single berth. The navigation station is located aft of the settee, facing outboard. The galley is located aft of the dinette, along the port side. It has a three-burner stove with oven, a double sink, a top-loading refrigerator and ample storage space.
The interior of the J40 is spacious, bright and well-ventilated. It has large windows, hatches and ports that provide natural light and fresh air. The woodwork is made of teak, which adds warmth and elegance to the cabin. The upholstery is durable and comfortable, and the cushions are thick and firm. The layout is practical and functional, with plenty of headroom, storage space and access to the engine and systems.
Hull and Deck
The hull of the J40 is made of fiberglass with balsa core for stiffness and insulation. The deck is also made of fiberglass with balsa core, except for high-stress areas where solid fiberglass is used. The hull-to-deck joint is bonded with adhesive and through-bolted with aluminum toe rail. The bottom is protected by an epoxy barrier coat to prevent osmosis.
The deck of the J40 is designed for safety and convenience. It has wide side decks, molded nonskid surfaces, stainless steel handrails and lifelines, and recessed hatches. The cockpit is large and comfortable, with high coamings, long seats, deep lockers and an integrated swim platform. The boat is steered by a single wheel mounted on a pedestal that also houses the engine controls, the compass and the instruments. The sail controls are led aft to the cockpit through organizers and clutches, making it easy to handle the boat single-handed or with a small crew.
