The USS Estelle (SP-747), later known simply as USS SP-747, was a United States Navy patrol vessel that served during World War I. Originally constructed as a private motorboat named Estelle, she was acquired by the Navy in 1917 to fulfill a patrol role along the U.S. coastlines. Although specific details regarding her construction, dimensions, and performance are not provided, her classification as a section patrol vessel indicates she was likely a relatively small, motor-powered craft designed for coastal defense and patrol duties. Commissioned in 1917, Estelle was assigned to patrol duties, presumably along the U.S. coast, during the remainder of World War I. Her service was relatively modest and not extensively documented, but she was an active part of the Navy’s coastal patrol force during this period. In 1918, her designation was changed from USS Estelle (SP-747) to USS SP-747, reflecting a common practice of renaming patrol vessels to streamline identification. After the war, her role shifted from active patrol to a more stationary or auxiliary function. On June 23, 1919, she was dispatched along with USS Ahdeek (SP-2589) to the Culver Naval School in Culver, Indiana. This suggests she was transferred to a training or loan arrangement, operating there on behalf of the Navy for an extended period. She remained in service until she was stricken from the Navy Directory in 1933, marking the end of her naval career. While specific notable events or significant maritime contributions are not detailed, her service exemplifies the routine coastal patrol and auxiliary roles played by private vessels acquired by the Navy during wartime. Her long tenure on loan to the Culver Naval School highlights her utility beyond combat, contributing to training and naval preparedness in the interwar period.
