The USS Cleo (SP-232) was a patrol vessel of the United States Navy that served during World War I from 1917 to 1918. Originally built as a civilian motorboat in 1908 by Johnson in Marine City, Michigan, she was later acquired by the U.S. Navy from the Michigan State Game, Fish and Forestry Department. The vessel was designated as USS Cleo (SP-232) upon her entry into naval service in April 1917, though it is unclear whether she was officially commissioned or served in a non-commissioned capacity. Constructed as a motorboat, specifics regarding her size, dimensions, or propulsion system are not provided in the available source. Her primary area of operation was the Detroit River and St. Clair River, located near Detroit, Michigan. During her naval service, Cleo functioned as a section patrol craft, contributing to local maritime security efforts during the wartime period. Her duties likely involved patrolling these strategic waterways to protect against enemy activity and ensure safe navigation, although detailed operational records are not specified. Cleo's service was relatively brief, ending in late November 1918, shortly after the conclusion of World War I. She was subsequently returned to her original owners, the Michigan State Game, Fish and Forestry Department, marking the end of her military service. Overall, USS Cleo (SP-232) exemplifies the many civilian vessels repurposed for wartime patrol duties along domestic waterways during the First World War. Her service highlights the importance of small patrol craft in maintaining security in critical inland river systems, although her specific historical significance appears limited to her local patrol area near Detroit.
