Lee Manvel is the man behind all of those modified hulls that shown up in Lake Havasu City during the World Finals. He had glass them all. The recipe involves a Kawasaki STX-15F bottom with a Sea Doo, Yamaha or Ultra top. You name it and he will do it. That is why most of these hulls use R&D ride plate and trim tabs. According to Lee Manvel the 15F hull has a great potential and it is very stable at high speeds (85+mph).
