Centerfold

A 7 ft 10 in plywood pram from Glen-L Marine that folds or takes apart across the middle, so a small cruiser can stow a tender that would otherwise not fit. Each half is light to carry, the mast on the sailing version can be made in two pieces, and it rows, sails or takes a 3 hp outboard. Glen-L publish a beam of 4 ft 0 in.

They put the usual load at 1 to 2 people. Sail area is 39 sq ft. The hull is an arc bottom pram, hard chine developed for sheet plywood planking. May be taken apart or folded across the middle for storage or portage. The pieces are non-nesting. For power they specify intended for rowing, sailing, or 3 hp max. Simple and cheap: no lofting, no building form, no frames. A beginner should allow 50 to 100 hours, more with the sailing rig, for which Glen-L sells hardware and sails. Medians from logged builds are below.
