About the HERRESHOFF 12 1/2

Gaff rig until 1936. From 1937 onwards, one could choose either a gaff or Marconi rig. The original boats were built by Herreshoff Manufacturing beginning in 1914 (357). From 1943 to 1948, more were built by Cape Cod Shipbuilding (34 + 200, later in fiberglass), as well as the Quincy Adams Yacht Yard (51). Cape Cod Shipbuilding came out with the BULLSEYE, built of fiberglass, with a similar hull but a different rig. The DOUGH DISH, (one of the many nicknames previously associated with the class)is a faithful rendition of the 12 1/2, first built in 1972 of fiberglass by Doughdish Inc., of which 575 were built. They have been recognized and approved by the class to race on equal footing with the remaining, original wood boats. Class rules permit a spinnaker of 140 sq. ft.

Sailpages Buyer's Take

Designed by Nathanael G. Herreshoff and built by Herreshoff Manufacturing Co., the Herreshoff 12 1/2 is a historic gaffhead sloop with 400 hulls constructed between 1914 and 1948. This data-driven synthesis highlights the boat's enduring legacy while identifying critical structural vulnerabilities common in this vintage fleet.

Best for:
This vessel suits coastal cruisers and traditional sailing enthusiasts who value classic aesthetics and manageable size, particularly those willing to invest in significant restoration and modernization.
Bluewater capability:
With a displacement of 1250.0 lb and a capsize ratio of 2.17, the boat is generally considered suitable for protected coastal cruising rather than serious offshore bluewater passage-making.
Comparables:
Comparable boats include other Herreshoff designs like the 12 Meter and 14 Meter, as well as contemporary gaff-rigged sloops from the early 20th century that share similar displacement and hull forms.
