A Dudley Dix designed Cape Henry 21′ that I recently built and launched for a Paris based customer. 3/8″ Okoume ply over ply bulkheads and Southern Yellow pine stringers, sheathed with 4oz glass on the bottom up to the first lap. Epoxy coated and finished with two part polyurethane paint.
The boat will be sailed here in West Cork, Ireland and has proven herself to be close winded, and easily driven by her sails. With a 6hp outboard in a cockpit well she maneuvers well in forward or reverse.
Down below there are two quarter berths, a galley and storage with V berth and porta potti forward of the mast. You can see the build process here www.roeboats.ie
