Design 68 - Dark Harbor 20

This design generates more inquiries than any other: The Dark Harbor 20. A bit of background: In 1932 a committee composed of members of local Long Island Sound yacht clubs was formed with the hopes of developing a new class of racing sailboat to compete with Atlantics and Sound Interclubs. The yacht clubs included Seawanhaka, Larchmont and American. One of the proposals was from the boards of Sparkman & Stephens. This proposal evolved into the Dark Harbor 20 class.

Twenty-one Dark Harbor 20s were built in the first half of the 20th century. The most active fleet is from the Tarratine Yacht Club of Isleboro, Maine with almost 20 boats still actively racing.

Here are the plans.

Here's a nice 3D model of the hull and keel shape.

  1. I first saw one on the calendar of Wooden Boats. I beleive it was a stern view of Eaglet ashore. Never forgot the looks of that boat.

  2. Just bought a cold-molded version of this design built by Brooklin Boatyard and finished by Rockport Marine. Sailed her for the first time this week. What a delight! She is very fast in a moderate breeze and ghosts along in light air. And she is the prettiest boat in the harbor (along with a great NY 32)!
