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.
Step-by-step photos of the prototype build come with the plans. Budget 450 to 750 hours. Real hours from logged builds are below.
What building a Thunderbolt actually takes
Medians from the build logs kept on this site, not the designer’s estimate. Nobody has logged this boat here yet, so they are empty until the first builder does.
Those medians firm up as more people log this boat.
