live-aboard
n.— «Seven years later, Diane and Gary O’Rourke have joined the ranks of sea lovers who call themselves “live aboards.” The couple, who own a boat maintenance company, Dockside Maid Service, keep their motor yacht docked just a few yards from their shop, at Norton Shipyard & Marina. Their boat is one of about 10 at the shipyard owned by people—couples, families and single men—who live year-round on their boats, said the shipyard’s owner, Pat Norton.» —“Home sweet home, docked in the Bay” by Lynn Arditi Providence Journal (Rhode Island) July 31, 2006.
