The USS Sea Otter (SP-781) was a wooden motorboat built in either 1911 or 1913 by the Britt Brothers in Lynn, Massachusetts. Originally a private vessel, the Sea Otter was acquired by the United States Navy on June 11, 1917, from her owner Hugh L. Willoughby of Newport, Rhode Island, to serve as a section patrol boat during World War I. Upon acquisition, she was commissioned the same day as USS Sea Otter (SP-781). Designed as a patrol vessel, the Sea Otter was employed primarily for transportation and supply duties along the United States East Coast throughout the duration of the war. Her role involved logistical support, ensuring the movement of personnel and essential supplies between ports, which was critical for maintaining naval operations during wartime. The vessel’s construction as a wooden motorboat made her suitable for the patrol and auxiliary tasks assigned to her. While specific dimensions and technical specifications are not provided in the source, her classification as a patrol vessel indicates a modest size and maneuverability tailored for coastal service. Following the conclusion of World War I, the USS Sea Otter was decommissioned and removed from active service. She was stricken from the Navy List on November 7, 1919. Subsequently, she was sold to Joseph Guild of Boston, Massachusetts, on January 16, 1920. The Sea Otter’s service exemplifies the Navy’s utilization of private vessels for wartime patrol and logistical support, reflecting a broader pattern of naval auxiliary operations during World War I. Her relatively short service life and subsequent sale mark her as a typical example of the many small craft that contributed to the U.S. Navy’s coastal defense and logistical efforts during the conflict.
