    Dictionary of American Naval Fighting Ships History: Soon after the United States entered World War I, Actus (SP-516) a yacht constructed in 1907 at Neponset, Mass., by George Lawley & Sons was taken over by the Navy from Mr. E. B. Dane; commissioned on 18 April 1917, Ens. H. A. D. Cameron, USNRF, in command; and, on 26 May 1917, over a month later, formally purchased by
    the Government.

    Assigned to the 1st Naval District, Actus spent the entire war patrolling Cape Cod Bay and the harbors of Boston and Plymouth. After the war ended in November of l918, she continued to serve the Navy at the Boston Navy Yard in some type of yard craft status. She also performed some unspecified service for the Naval Overseas Transportation Service office at Boston in May and June of 1919. She was decommissioned at Quincy, Mass., on 8 July 1919. A little over a year later, on 20 July 1920, she was transferred to the War Department. Presumably her name was struck from the Navy list at about the
    same time.
