About the DARK HARBOR 20

In 1932 a committee composed of members of local yacht clubs around the east coast (USA) was formed, to develop a new one-design class. Based on 'Gimrack', an earlier Olin Stephens design. 21 were built. A number have been restored, and/or reproduced, and are seen, to this day, in the coastal waters of Maine (USA). A fiberglass version was approved for class racing in 2005.

Sailpages Buyer's Take

The Dark Harbor 20 is a rare, historic vessel designed by Olin Stephens and built by George Lawley (USA) in 1934, with a total production run of only 21 hulls. As a 30.0 ft LOA fractional sloop with a displacement of 5200.0 lb, it represents a significant piece of American yachting history rather than a mass-produced model.

Best for:
This boat is best suited for collectors, historic boat enthusiasts, or coastal cruisers seeking a unique, classic aesthetic with moderate performance characteristics. Its small build count and age make it a niche choice for those prioritizing provenance over modern convenience.
Bluewater capability:
With a displacement of 5200.0 lb and a capsize ratio of 1.55, the Dark Harbor 20 exhibits a heavy, stable hull form that suggests reasonable offshore capability for its size, though its age and single-year production limit widespread bluewater track record data.
Comparables:
Comparable vessels include other 1930s Olin Stephens designs such as the Columbia 26 or early Pearson models, which share similar fractional sloop rigs and heavy displacement characteristics. These boats are comparable due to their era-specific construction methods and emphasis on seaworthiness over speed.
