Arval (SP-1045)—a motorboat constructed in 1911 at Stamford, Conn., by the Stamford Motor Co.—was acquired by the Navy on free lease from Mr. Donald N. Test on 1 November 1917 and was placed in commission at Chicago that same day, Ens. Franklin Smith, USNRF, in command.
She departed Chicago on the day of her commissioning and arrived in Charleston, S.C., on the 7th. She was assigned to the 6th Naval District section patrol and was based at Wilmington, N.C.
