General Details

Here is an opportunity to own something special, the former personal yacht of a well known yacht designer. With many unique features, WYNWARD will give her next owner a great deal of pleasure and satisfying performance.


Beam: 15'1'' Max Draft: 3'11'' Displacement: 38,000
Sleeps 4 owners and guests in two staterooms with two heads and two showers. The Master Stateroom sleeps two and is aft with queen berth, head, and separate stall shower. There is one Guest Stateroom forward with two berths, head, and separate stall shower. WYNWARD was the personal yacht of the late Jim Wynne; he lived aboard for eight years and did extensive cruising in the Bahamas and Florida Keys aboard her. Some of Jim's accomplishments and designs are the invention and granting of a patent for the inboard/outboard stern drive which he sold to Volvo Penta, the Hatteras 32', Hatteras 36', the complete Cruisers Inc. line - up to 1991, the complete Phoenix line - up to 1991, as well as models for Albin, Carver, Chris Craft, Cigarette, Donzi, Magnum, Queen Long, Trojan, and many other well known boats. Jim also originated the “propeller pocket” or tunnel and he used that design onboard WYNWARD. WYNWARD combines the qualities of both a planing hull and a displacement hull. WYNWARD will cruise economically at 9 knots consuming 8 gallons per hour, or she will cruise at 17 knots for those times when speed is important. WYNWARD has many unique design features including 36 patents applied for with the building of WYNWARD. There are no ladders anywhere on board with the exception of the ladder from the cockpit down to the swim platform; all areas are accessed by stairs. The machinery space is located all the way aft under the cockpit with very short shafts turning propellers in tunnels eliminating vibration; this machinery space is separated from the rest of the living area by an insulated full bulkhead. The swim platform is actually part of the hull increasing the waterline length and inhibiting exhaust mist from being pulled back into the cockpit from her under-transom exhaust. The hardtop flybridge (Portuguese bridge) area is accessed by the steps, either port or starboard (no ladders); the full walk-around bridge area gives an added sense of security as well as easy access to the foredeck. Below decks the Guest Stateroom is forward and has two large comfortable berths, ample lockers, shelves, and hanging locker space with en-suite head and separate stall shower. Amidships is the full beam Main Salon with L-shaped settee and Hi-Lo table forward to starboard, and wet bar with ice maker and custom bottle storage to port. On the port side aft in the salon is the U-shaped full Galley with breakfast bar immediately forward. This salon/galley area has a light and airy feeling due to the large windows both port and starboard giving a full panoramic view of the outside even when seated in the salon. Aft of the salon, down two steps is the full beam Master Suite. This stateroom has a queen sized berth on centerline with six oversized drawers underneath, and double hanging lockers. There is a lady's dressing table to port with eight drawers and an additional mirrored area forward with two drawers. The en-suite head is to starboard with a full stall shower. Interior upgrades: Master head structure completely rebuilt Rebuilt both heads with pumps and PVC plumbing hoses and valves New stainless steel ice maker in Salon wet bar New headliner in Salon New wall coverings in Salon New wall coverings in forward cabin New headliner in forward cabin New headliner in master stateroom New wall coverings in Master Stateroom New carpet in Salon New carpet in Master Stateroom New teak flooring in Galley New teak flooring in forward Guest Stateroom
Additional Features
WYNWARD's hull was built in Medley, Florida by Marine Management and then taken to Dania where she was finished by well-known shipwright Howard Abbey. WYNWARD was built to cruise the shallow waters of south Florida and the Bahamas. She has a draft of less that four feet (4') with her keel being the lowest point. Her design has a full keel with propeller pockets offering excellent protection for the running gear in shallow water as well as providing very good longitudinal tracking underway.

WYNWARD was built and lived aboard by famous naval architect James Wynne. She is a commercial fishing boat hull made by Marine Management with the keel laid in 1976. The house was custom built by noted shipwright Howard Abbey. WYNWARD was such an innovative boat that she was featured in "Nautical Quarterly" Volume 8 and was the cover boat for the May 1978 issue of "Boating" magazine. Copies of these articles are available (portable document format) upon request. Here is an opportunity to own something special, the former personal yacht of a well known yacht designer. With many unique features, WYNWARD will give her next owner a great deal of pleasure and satisfying performance. Updated & upgraded - ready to cruise!
