18 ft Cat Ketch

Designed by Jay R. Benford

An 18 ft design from Jay Benford's catalog, drawn for plywood construction. A flat-bottomed camp cruiser carrying the lessons from the 16 ft Sailing Tender before her. Simple to build and civilised to use. One of the fifteen designs in Small Craft Plans, the book that carries complete working drawings and tables of offsets so a builder can work straight from its pages rather than ordering plans. The designer still recommends lofting full size and taking the rest of the dimensions off the lofting, on the grounds that the time spent is paid back several times over during the build.

Benford publishes a displacement of 200 lb in coastal cruising trim, which is tanks full with the crew and their stores aboard rather than a shipping weight. Plans are sold to owner-builders; professional builders are directed to a licensing agreement instead.
