(Houseboat: dp. 6.16; 1. 31'2"; cpl. 6)
Early in World War I, the second A-1—a houseboat built in 1911 by Sillit Buchanan—was inspected for possible naval service. Her takeover by the Navy from F. E. Wright of San Pedro, Calif., was ordered on 6 October 1917. The vessel was placed in service on 30 December 1917, and she operated in waters of southern California through the end of hostilities. Her logs end on 9 December 1918 and, apparently, no record of her subsequent fate has survived.
