In their early days, Edgewater was described as a small company living on the leading edge of technology. If anything, that’s truer today. The most noteworthy aspect of this 318 has to be its unusual construction technology. The company refers to it as SPI (Single Piece Infusion).

After spraying the gelcoat layer, Edgewater lays in all the dry ingredients, such as specially engineered fiberglass, Divinycell coring and the like, including the stringers. Then it encases the mold in a plastic bag with a strong vacuum pump attached at one end and the vinylester resin supply on the other. Turn on thevacuum and the pump sucks the resin throughout the laminate. The bag, combined with the vacuum pressure, prevents excess resin buildup and any air bubbles or voids. The resultant hull has an optimum glass-to-resin ratio.

The transom and stringer grid are made from composite and glass, so you’ll find no wood in the Edgewater. Additionally, Edgewater bonds the stringers into the hull right from the start rather than gluing them in after the hull is finished. Eliminating excess resin means a lighter boat without sacrificing strength, and of course lighter means better performance, too. As a result, the 318 runs extremely well with just two engines.

Another improvement in the 318 finds hatches upgraded from basic StarBoard to the two-part, finished-on-both-sides variety. And of course, like all Edgewaters, the 318 is unsinkable no matter what you do to it.
