Portage Pram

Designed by Bill Peterson

A 6 ft 10 in plywood pram that weighs about 35 lb, made as a tender and a first build. It is a light stitch-and-glue version of a much heavier plank-on-frame pram that Bill Peterson designed at Murray G. Peterson Associates in the 1970s, a boat long known for being stable and tracking well under oars. The inwales take oarlocks in several positions, so the rowing station can be matched to the crew.

An optional sailing rig sets about 45 sq ft on a sleeved, full-battened sail with no boom over a two-piece fiberglass mast. The CNC kit locates its parts with tabs and pockets and goes together mostly with zip ties and epoxy. Kit Boats Co. rates the build easy, at about 50 hours. Real hours from logged builds appear below.
