Like its other models, EdgeWater builds the 388 using the proprietary construction process it calls Single Piece Infusion. With SPI, EdgeWater lays the fiberglass, carbon fiber and composites such as Nida-Core, Divinycell and Airex foam coring into the mold along with the structural stringer grid. It then vacuum-bags the lot, infusing the dry ingredients with vinylester resin all at once. This method ensures there are no air voids or extra weight from too much resin, and that all parts cure exactly the same for an unsurpassed strength-to-weight ratio. Add to that oversize rails, high-quality hardware, deep cockpits and higher gunwales, and you begin to see why EdgeWater touts its safety- and comfort-first philosophy.
