The majority of these boats were lost in a boatyard fire in 1974, effectively destroying a class that had raced on Long Island Sound (Manhasset Bay) since they were first imported from Norway in 1955.
Many thanks to the William Tripp Design Office for providing images and general information concerning this yacht.
