Jon Boat

Designed by Grandpa's Archive

This is a later magazine printing of the same 12 ft square-ended skiff, with the same Statement of Uses: 5 ft beam, 110 lb, room for three to five adults and outboards of 1 to 6 hp. It is a historical flat-bottomed type, framed in wood and skinned in AC exterior plywood, and was sold to readers as a light car-top boat for rivers and marshes.

The text in this version spells out a few details the other scan does not: framing glued and fastened to the poor side of the plywood with ringed nails slanted for grip, a 3/4 in motor board on the transom, and an iron bar used as a dolly while nailing. Builders comparing the two scans may find it useful to read both.
