Scratch built 4 degree shallow vee. Y.S 60 aircraft engine converted to marine. Double planked hull. Birch ply with mahogany planking. Finished with 3/4 oz cloth and epoxy resin. Finished 2 seat cockpit. In board hand made wet pipe and drive. Hull is 36" long with a 13" beam. 3 1/2" at deepest point. C/G at 29%. Prather 260 prop. I built this boat in 2000. I ran it for 5 years before retiring it. The last engine to run in it was a 91 O.S Max S.X. H Ring C spec. It was an ex race Helli engine I convereted to Marine. It was the fastest boat on the pond for those 5 years. How fast -mph I dont know for sure. I'd only be guessing. Scary Fast!
