San Juan Composites, LLC

Gregory C. Marshall Naval Architect Ltd.& SANJUANYACHTS Design Team


San Juan Composites LLC is pleased to introduce the new SJ40FB, our newest fly bridge model in our series of cruising lobster boat styled motor yachts.

We have heard from many SanJuanYacht owners and prospects over the years that have expressed a desire for us to build a high quality “lobster boat” styled fly bridge motor yacht in the 40-foot range. This demand has prompted us to design and build our SJ40FB,which shares the handsome good looks of ourSJ48FB. Our SJ40FBcombines lobster boat styling with state of the art design, engineering and composite construction to handle the rugged, no-nonsense environment of any ocean or waterway. Working with Gregory C. Marshall Naval Architects, our SanJuanYachts design team have designed a yacht on our proven hull form which provides comfort and sea keeping in difficult sea conditions yet allows for higher speed cruising in calm to moderate sea conditions.

At 40’-7” x 12’-2” Beam our SJ40FB offers a premium level of interior space in a highly functional interior/exterior layout complimented with the addition of our flying bridge.

Our industry recognized standard is used in building interiors, which offer unmatched care and craftsmanship. This standard includes fit and finish of joinery and systems, which is normally only available in the mega-yacht market.

The SJ40FB, like all of our SanJuanYachts models, comes complete with an extensive list of standard equipment, which includes most items normally offered as optional equipment by others.

Performance for the SJ40FB includes a cruise speed of 30 knots made possible by its lightweight resin-infused composite structure and standard Yanmar 6LY3-UTP (380 hp) turbocharged diesel engines. 480 HP Yanmar diesels are offered as an option.

The SJ40FB has been designed to be extremely maneuverable with engines located for balance and stability. It will easily spin and maneuver in its own length with intuitive ease using our standard electronic controls. Maneuvering is further simplified with joy stick controlled bow and stern thrusters as standard equipment.  

The SJ40FBis built in the USA using the American Bureau of Shipping Rules as guidelines. Machinery and equipment are installed using the rules and regulations of the United States Coast Guard and the American Boat and Yacht Council as guidelines.

The result is yet another safe, high performance, personal motor yacht for the boat owner looking for unmatched fit, finish and attention to detail.


The SJ40FBhull has been designed and computer modeled to be both handsomely styled and capable in a broad range of sea conditions. The traditional flared bow with fine entry and tumble home aft is complemented by the hydro-dynamically efficient underbody.   Tooling for the entire boat was modeled and cut by a computer controlled 5-axis router creating the most fair and precise parts available in the industry today. The SJ40FB hull is formed using a Kevlar® / E-glass and Corecell® foam core composite infused with vinylester resin. Dupont Kevlar® / E-glass hybrid is used to greatly increase the strength of the hull against damage caused by impact. The infusion process yields strong lightweight parts with high glass to resin ratios. The core is removed and replaced with solid glass and extra laminations in areas of major penetrations and high stress. Four composites watertight structural bulkheads separate the hull into damage control zones with dedicated bilge pumps. Structural bulkheads are built using Corecell® foam core with E-glass skins infused with vinylester resin. Longitudinal and transverse stringers are an E-glass Corecell® foam core composite. The entire structure of the boat is built using wood free composites


The deck is a one piece infused composite molding using E-glass and Corecell® with vinylester resin. The hull is joined to the deck using an engineered flanged box joint and is bonded using a high strength adhesive with mechanical fasteners. This provides a permanent, watertight hull/deck joint.


The large cockpit was designed to allow ample room for sitting, dining, fishing and sunbathing. An opening walk through transom door provides easy access on and off the boat via the swim step. The built-in transom seat provides both seating and underside bin storage. Storage bin is removable to provide additional storage space below in the lazarette. Bin may be used as a cooler or may be set up as bait locker as an option for fishing. Sitting and sunbathing space is also available on the port and starboard engine compartment boxes with hatches that lift with the aid of lifting cylinders for engine access. Engine compartment hatches are supplied with non-skid surfaces or teak decking as an option. The cockpit deck is molded with 1” waterways. Teak decking is standard for the cockpit, pilothouse and on the composite swim step. A flush hatch in the deck provides easy access to the engines and generator.
