The USS Raccoon (SP-506) was a wooden-hulled motorboat built in 1915 by George Lawley & Son in Neponset, Massachusetts. Originally constructed as a private vessel, she was launched and completed that same year. The boat's design featured a classic wooden hull, suitable for swift patrol duties, and was owned by Francis W. Fabyan of Cambridge, Massachusetts, prior to her naval service. In response to World War I, the U.S. Navy acquired the vessel on 5 May 1917 for use as a section patrol boat. Upon acquisition, she was commissioned as USS Raccoon (SP-506), marking her transition from private to military service. During her naval career, Raccoon primarily operated along the northeastern coast, initially stationed in New London, Connecticut, where she conducted patrols until December 1917. Subsequently, she was transferred to Newport, Rhode Island, where she continued her patrol duties through the end of World War I. The vessel's armament was removed on 3 December 1918, signaling the end of her military patrol duties. She was formally returned to her owner, Francis W. Fabyan, on 17 January 1919, and resumed her role as a private motorboat. In 1924, she was renamed Constance after changing owners. However, her appearance in mercantile registers ceased in 1925, indicating she likely left commercial service or was otherwise decommissioned. The USS Raccoon (SP-506) exemplifies the common practice during WWI of converting private vessels for military patrols, contributing to coastal defense efforts. Her service life was relatively brief but reflects the importance of small, versatile patrol craft in maintaining maritime security during the war.
