The first Scoter, a privately owned wooden boat, was built during 1916 by George Lawley and Sons, Neponset, Mass.; was inadvertently assigned two numbers, (SP 20) and (SP-53), the latter of which was later assigned to Boy Scout. Enrolled in the Naval Coast Defense Reserve for possible United States Naval service in World War I; she was delivered to the Navy by her owner, J. L. Saltonstall of Boston, Mass., on 21 April 1917 and placed in service on the same day.
Assigned to duty with naval forces in Europe, Scoter was carried across the Atlantic on a larger ship and probably operated in French waters into 1918. Unaccounted for, she was dropped from the Navy list in 1919.
