Thunderbolt

Designed by Glen-L Marine

A 17 ft 3 in vee-drive high-performance ski boat from Glen-L Marine, built for one thing, speed; two Australian brothers held three gold cups with one powered by a big-block Chevy. A slanted transom is standard with a vertical option, and the stern-mounted engine is usually left exposed and chromed. Vee-bottomed sheet plywood, about 650 lb. Glen-L publish a beam of 6 ft 11 in and a hull depth of 25 in.

They put the usual load at 2 to 4 people. The hull is a vee bottom with flaring sides that act as anti-trip chines. Developed for sheet plywood planking. For power they specify inboard, stern mounted engine driving through a v-drive. They draw a matching trailer for her. Step-by-step photos of the prototype build come with the plans. Budget 450 to 750 hours. Real hours from logged builds are below.
