TNT

An 11 ft outboard runabout from Glen-L Marine styled after the big inboard ski boats, with flaring anti-trip sides, planked entirely, side decks included, from three standard sheets of quarter-inch plywood. Outboards to 15 hp.

Simple and easy to build, with step-by-step instructions. Allow 120 to 220 hours. Real hours from logged builds show below.
