The USS Normannia (SP-756) was a United States Navy patrol vessel constructed as a private motorboat in 1912 by Fellows Boat Works in San Diego, California. Originally owned by F. Thum of Pasadena, the vessel was acquired by the U.S. Navy on 10 July 1917 through a free lease, reflecting its intended use for wartime patrol duties during World War I. On the same day, she was commissioned as USS Normannia (SP-756). Designed as a motorboat suitable for patrol and harbor security, the Normannia served primarily within the 12th Naval District, based out of San Francisco. Her operational role involved patrolling the harbor entrance, safeguarding the coastline stretching between San Francisco and San Diego, and performing special sea duties. Starting from 13 August 1917, she actively participated in patrol missions, contributing to the maritime defense during the war. Throughout her service, the Normannia frequently alternated between guard and patrol duties at San Diego, especially around December 1917. During this period, she operated alongside other patrol vessels such as USS Albacore (SP-751), USS Rosa (SP-757), USS Nomad (SP-1046), and occasionally USS Natalie Mae (SP-1005). These operations were critical in maintaining security in the busy coastal and harbor areas during wartime. After concluding her naval service, the USS Normannia was returned to her owner, F. Thum, on 23 December 1918, shortly after the end of World War I. Her brief but active service highlights her role in the U.S. Navy’s coastal patrol efforts during a critical period of maritime security. The vessel's service underscores the Navy's utilization of private motorboats for patrol duties, contributing to the overall maritime defense strategy during the war.
