Marie, Michigan, for the duration of World War I, Voyager operated actively on the Great Lakes until winter ice stopped navigation.

Departing on that day, Voyager set out in company with Isla de Luzon, Avis, Mikawe, Dicky, and Raboco.

Her motor broke down on 11 May, however, necessitating the SP boat's being towed back to her home port of Sault Ste.

Simultaneously struck from the Navy List, Voyager was turned over to the Treasury Department for use by the United States Coast Guard at Chicago, Illinois, on 15 September 1919.

She was purchased privately in 1936, and operated as the fishing vessel Marley Grace on Lake Superior until 1944, when she was scrapped by her owner.
