Headquartered in Amityville, New York, Sumner Boat Company successfully created a series of popular small sailboats through the latter half of the 20th century. Fiberglass recreational craft ideal for day sailing, Sumner Boat Company vessels ranged in lengths from 12 to 19 feet. While solely producing sailboats from the late 1970s through to its final year of production in 1995, the history of Sumner Boat Company recognizes the Sumnercraft brand of motorized sailors sold in the 1960s.
