Sayonara II, a motor boat built in 1916 by George Lawley and Sons, Neponset, Mass., was acquired by the Navy on 25 April 1917 on a $1.00 a month lease from Charles Blum of New York City. Designated SP-587, she was placed in service on 8 May, Chief Boatswain R. F. Grassie, USNRF, in charge, and assigned to the 1st Naval District for section patrol duty. After the end of World War I, she remained on duty in that district until she was placed out of service in March 1919 and returned to her owner.
