Tornado

An 18 ft 6 in low-profile vee-drive ski boat from Glen-L Marine with flaring anti-trip sides, a smooth tumblehome into the deck at the transom, bucket cockpits and the engine left exposed for show. Vee-bottomed sheet plywood, about 725 lb; stern-mounted inboard to 800 lb on a vee drive.

Rugged but relatively simple to build, with Glen-L's interlocking motor-stringer method. Budget 500 to 850 hours. Real hours from logged builds are below.
