The USS Mist (SP-567) was a United States Navy patrol vessel that served during World War I from 1917 to 1919. Originally constructed as a private steam launch, Mist was built in 1904 by the Herreshoff Manufacturing Company in Bristol, Rhode Island. The vessel's design as a private steam launch suggests a relatively small, sleek craft suitable for both leisure and light transport, though specific dimensions are not provided in the source. In April 1917, amidst the United States' entry into World War I, the Navy informally acquired Mist from her owner, Edward Morell, to bolster its coastal patrol capabilities. She was formally commissioned as USS Mist (SP-567) on 28 April 1917, with the official acquisition completed on 12 May 1917. Her primary assignment was within the 1st Naval District, covering northern New England and centered around Boston, Massachusetts. During her wartime service, Mist performed a variety of duties including acting as a dispatch boat, guard boat, and supporting minesweeping training operations. Her role in these activities was critical for maintaining security and safety along the busy maritime approaches to Boston. She contributed to the efforts of the Mine Sweeping Division, which conducted training along the Massachusetts coast, ensuring the readiness of minesweeping operations vital for safe navigation and harbor security. After nearly two years of service, the USS Mist was returned to her owner, Edward Morell, on 3 February 1919, following the end of World War I. Her service highlights the use of private vessels for auxiliary and patrol roles during wartime, reflecting the Navy’s adaptability in utilizing civilian craft for national defense. The vessel’s modest but essential contributions to coastal security and mine-sweeping training mark her as a notable example of small patrol craft during the wartime period.
