21 ft Gaff Sloop

Designed by Jay R. Benford

A 21 ft design from Jay Benford's catalog, drawn for C-Flex fibreglass construction. One of the cruising sail designs, the part of the catalog that dominated the office for years and fills Cruising Designs.

Benford publishes a displacement of 2,950 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, and study plans are sold separately for anyone wanting to look before committing.
