Since molding a poly body is such an expensive proposition, the "gorilla hull" might work. It's a lot less expensive to build a mold for fiberglass than to tool up for poly forming. This business is located a short drive from my home, and I know the owner. The gorilla Hull is guaranteed for the life of the "boat" and if I remember right it's made with Kevlar. Just something to think about. If you ever decide to go into production, I'll try my best to get in on it, I want to be in the R&D dept.
DESTRUCTION is just a couple of vowels down the street from DISTRACTION
