The lapstrake plywood Cape Henry 21 developed naturally out of the Cape Cutter 19, a GRP trailer sailer that has become very popular in a short time and has sold 70 boats in its first 2 years in the UK market. The 19 proved to be a boat that is full of character, able and seaworthy, with a surprising turn of speed. |

The hull is styled after the traditional sailing craft of England, which have spawned many modern interpretations of the basic concept. It is lapstrake plywood in construction, with carefully proportioned curves and strake widths to produce a pretty hull. In lapstrake hulls the chines are accentuated by the step in the joint, so an unfair line looks very ugly. |
The interior arrangement is a straight copy of the 19, with small galley, double forward berth and quarter berths. The extra length gives more foot-room to the forward berths and enough length to the quarter berths to allow Mom and Dad to sit comfortably after the kids have turned in. A portable toilet lives under the aft end of the forward berth and can be screened with a privacy curtain. |

Building on the achievements of the Cape Cutter 19, the Cape Henry 21 looks like also becoming a popular little boat. Many of these boats are built from scratch but she is available as a plywood kit from suppliers in Australia, South Africa, Turkey, UK and USA. We include full size Mylar patterns of the bulkheads with the stock plans, to assist those building from scratch. We also offer optional Mylar patterns of the hull panels, useful for those builders who are concerned about cutting the correct shapes for the hull skin. |
