Sneak Box

Designed by Glen-L Marine

A 12 ft 5 in plywood take on the Barnegat Bay sneak box from Glen-L Marine, the low-profile duck-hunting boat that also makes a light recreational sailer with its sprit rig and daggerboard. Five sheets of plywood plank it, it weighs about 115 lb, and it takes oars or an outboard up to 5 hp. Glen-L publish a beam of 4 ft 6 in and a hull depth of 14 in.

They put the usual load at 1 to 2 people. Sail area is 51 sq ft. The hull is a vee-bottom hard chine developed for sheet plywood. For power they specify oars or outboard motor to 5 hp. They draw a matching trailer for her. Straightforward: no building form or jig, full-size patterns and a vee-bottomed hard-chine hull. Allow 100 to 180 hours. Real hours and months from logged builds show below.
