Cape Henry 21

A 6.38 m (20 ft 11 in) on deck traditional trailer sailer by Dudley Dix, a lapstrake plywood development of the Cape Cutter 19 with about a third more volume. It displaces 1,450 kg with 520 kg of ballast, sets 306 sq ft of gaff or Marconi rig, sleeps four, and comes with a centreplate or bilge keels. It stays within normal towing width, and Dix reports more than 70 plan sets sold.

Permanent bulkheads and a plywood backbone lock together egg-crate style, and stringers at the chines make the planking easier for amateurs. Dix says any handyman of reasonable ability can build it. Kits, builders' notes and a builders' forum exist. Budget roughly 1,200 to 1,800 hours. The medians below come from builders who logged this boat here.
