The Pacific Northwest was the cradle of lightweight fiberglass motoryacht construction. Located in Anacortes, Washington, San Juan Yachts has the advantage of this knowledge base and its 65,000-square-foot facility is home to 85 craftsmen. Like her sisters, the 40FB's major tooling was sculpted by computer to exact tolerances. Her hull is built using an infusion process with vinylester resin, Kevlar, E-glass, and core-cell foam. The hull is divided structurally into four watertight compartments. Her house, bridge, and decks are built in the same fashion and no wood is used in her structure. Infusion, the process of drawing the resin into the reinforcement in a vacuum, allows the resin and glass ratios to be carefully controlled. This produces more consistent results and structural properties that would be difficult to achieve by hand lamination in a production environment. Exterior surfaces are finished with AlexSeal in a climate-controlled spray booth. Here again, the net result is well above average.
