The USS Bonita (SP-540) was a United States Navy patrol vessel constructed as a private pleasure craft by the Holmes Motor Company in Mystic, Connecticut. Although specific dimensions are not provided, as a private vessel repurposed for military use during World War I, she was acquired by the Navy on 17 May 1917 from her owner, Mr. Robert Windsor of Boston, Massachusetts. Commissioned shortly thereafter as USS Bonita (SP-540), she was designated as a section patrol vessel. As a patrol vessel, USS Bonita was assigned to the 1st Naval District, where she conducted patrol duties primarily within Boston Harbor. Her role was to secure the harbor and monitor for enemy activity during the ongoing war, contributing to the defensive operations along the U.S. eastern coast. Her service was relatively short-lived, spanning from her commissioning in 1917 until her sinking in 1918. On the night of 26 November 1918, just after the end of World War I, USS Bonita was involved in a collision with the fishing schooner Russell. The collision resulted in the sinking of the Bonita before dawn. Despite efforts to locate and recover the wreck, her remains were not found, and she was officially stricken from the Navy List on 18 December 1918. The USS Bonita's brief service highlights her role as a wartime patrol vessel, contributing to harbor security during a critical period. Her sinking underscores the hazards faced by naval vessels operating in congested harbor areas, especially in the immediate post-war period. Although her operational history was short, her service exemplifies the Navy’s utilization of private vessels for patrol duties during World War I.
