Notes: Gaff rig until 1936. From 1937 onwards, one could choose either a gaff or Marconi rig.\nThe original boats were built by Herreshoff Manufacturing beginning in 1914 (357). \nFrom 1943 to 1948, more were built by Cape Cod Shipbuilding (34 + 200, later in fiberglass), as well as the Quincy Adams Yacht Yard (51).\nCape Cod Shipbuilding came out with the BULLSEYE, built of fiberglass, with a similar hull but a different rig.\nThe 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.\nClass rules permit a spinnaker of 140 sq. ft.
