 In 1917, the U.S. Navy chartered her from her owner for use as a section patrol boat during World War I and took delivery of her on 8 October 1918.No logbooks exist to confirm that she was commissioned as USS "Arcadia" (SP-856) or to describe the extent and nature of her U.S. Navy service.Given the short period the Navy controlled her and the ending of the war just under five weeks after her acquisition, it is possible that she never was commissioned.
