The USS Sentinel was a motorboat constructed in 1918 by Richardson Boat Co. in North Tonawanda, New York, specifically for the United States Coast Guard. The vessel was completed on June 17, 1918, during the final months of World War I. Designed as a patrol craft, the Sentinel was assigned to the St. Mary's River patrol area, based in Sault Ste. Marie, Michigan, where it contributed to maritime security and surveillance efforts during the wartime period. The ship's specifications are not detailed in the provided content, but as a motorboat built for patrol duties, it would have been relatively small and maneuverable, suitable for patrolling inland waterways and border areas. Its construction by Richardson Boat Co. suggests it was a purpose-built vessel capable of supporting Coast Guard missions such as law enforcement, search and rescue, and general maritime patrol. Following the end of World War I, the USS Sentinel was returned to the United States Coast Guard when the wartime naval services were separated on August 28, 1919. The vessel continued its service with the Coast Guard until 1935. Notably, in 1923, the Sentinel was renamed AB-13, reflecting a change in its designation or classification within the Coast Guard fleet. Overall, the USS Sentinel served as a patrol vessel during a critical period of maritime security, contributing to the Coast Guard's efforts in inland and border waters. Its service history, while not marked by any widely known notable events, exemplifies the maritime roles undertaken by small patrol craft during and after World War I. The vessel's significance lies in its contribution to early 20th-century maritime patrol operations and its representation of Coast Guard auxiliary naval capabilities during that era.
