No Man's Land boats

Use for double-ended workboats, 16 to 22 feet long, originally keeled, with a hole at each end of the keel, two masts, usually with small spritsails, and later fitted with off-center centerboards; designed to be launched and beached through the surf and developed in the late nineteenth century for lobster and scallop fishing around Martha's Vineyard, Massachusetts, and along the Rhode Island coast.
