Jon Boat / Garvey 12: builds and build times

Jon Boat / Garvey 12

A 12 ft flat-bottom garvey by Jacques Mertens, sold by Bateau / Boat Builder Central as the GF12 and equally at home as a jon boat or duck boat. Beam is 5 ft, hull weight about 115 lb and draft 6 in, with 10 hp recommended. It is quick with a small outboard and very stable. Sister designs run to 14 ft and 16 ft.

Stitch and glue, with the bottom a plywood-cored glass sandwich. Most cuts are straight lines, and the designer says a first-time builder can do it. His figure is 20 hours for the hull and 40 or more finished; a first build more often takes 60 to 120. Measured medians from build logs appear below.
