About the FISHERS ISLAND 31

Conceived as a racing class for summer residents of Fishers Island, NY USA. Herreshoff Manufacturing delivered the first boat just before the stock market crash of 1929 and production of the first 12 ended just one year later. At least one of the original boats survives and has been on display at Herreshoff Museum.

Sailpages Buyer's Take

The Fishers Island 31 is a rare, classic fractional sloop designed by Sidney Herreshoff and built by Herreshoff Manufacturing Co. (USA) between 1928 and 1946, with only 14 hulls constructed. Its authoritative specifications list a LOA of 43.5 ft, LWL of 31.5 ft, and a displacement of 18000.0 lb, reflecting a heavy, full-keel design with a comfort ratio of 34.24.

Best for:
This vessel suits experienced coastal cruisers and classic boat enthusiasts who prioritize seakindliness and traditional aesthetics over high-speed performance. It is well-matched for those willing to maintain vintage systems and invest in modern upgrades like wind generators and watermakers for extended cruising.
Bluewater capability:
With a displacement of 18000.0 lb, a low capsize ratio of 1.62, and a full/long keel, the boat possesses inherent stability and motion comfort suitable for offshore passages, provided structural integrity is verified.
Comparables:
Comparable vessels include other Herreshoff designs and heavy-displacement full-keel yachts from the 1920s–1940s era, such as the Columbia 30 or early O'Day models, due to similar build quality and conservative hull forms. Its fractional sloop rig distinguishes it from many contemporaries that utilized masthead rigs.
