The USS Elfin (SP-965) was a United States Navy patrol vessel that served during World War I from 1917 to 1918. Originally built as a private motorboat in 1911 by Britt Brothers in Lynn, Massachusetts, the vessel was designed for civilian use before being acquired by the U.S. Navy. In July 1917, the Navy leased the Elfin from her owner, Alfred W. Gibbs of Wayne, Pennsylvania, to fulfill wartime patrol duties. Constructed as a motorboat, the Elfin’s specific dimensions and technical specifications are not detailed in the provided source, but as a patrol vessel of the era, she was likely a relatively small, agile craft suitable for coastal patrols and escort duties. She was commissioned into Navy service on July 26, 1917, and assigned to the 4th Naval District, an area encompassing parts of the northeastern United States. During her service, the USS Elfin performed patrol duties, which would have involved monitoring coastal waters for enemy submarines, ships, or other threats, as well as ensuring maritime security during the ongoing conflict. Her operational history appears to be straightforward, with her primary role being patrol and surveillance within her assigned district. Following the end of World War I, the Navy returned the Elfin to her owner, Alfred W. Gibbs, on November 22, 1918. Her service duration was relatively brief, but her role as a patrol vessel contributed to the broader maritime security efforts of the United States during the war. The USS Elfin exemplifies the common practice of the U.S. Navy augmenting its fleet with private vessels during wartime, utilizing smaller, privately owned boats for patrol and security functions.
