A 20' Dolphin Mike and Perry re-did 20 years ago, all in composite. Still Rock solid. Inside of the Dolphin...
It is a 1978 Dolphin. The stringers were foam filled, and had old wet foam. The something busted loose around the fuel tank, the hull split and the boat sank. Mike towed it in, fixed it, and then bought it from the guy. They later went back in and reglassed the stringers and beefed them up. They re-foamed it with modern foam and cut the liner out, then added a new floor.
