The USS Sister (SP-822) was a small steam-powered tug built in 1882, originally serving as a commercial vessel. The ship was constructed for use as a tug and freight boat, featuring a robust design typical of small maritime tugs of the late 19th century. In 1917, during World War I, the U.S. Navy acquired her from her owner, L. F. Young of Madisonville, Louisiana, reflecting her utility for wartime service. The Navy formally purchased her on June 29, 1917, and she was commissioned shortly thereafter on June 11, 1917, with the section patrol number SP-822. During her naval service, Sister was assigned to the 8th Naval District, where she primarily functioned as a tug and freight vessel. Her duties involved assisting larger naval ships and transporting supplies within the district, based out of Madisonville, Louisiana. There are claims that she also performed patrol duties, which was a common secondary function for vessels of her type during wartime, although specific details of her patrol activities are limited. The vessel’s service continued through the end of World War I and into 1919, after which she was stricken from the Navy List on June 17, 1919. Following her decommissioning, she was sold to Armond Mayville of Algiers, Louisiana, either on March 10 or October 3, 1920. The USS Sister’s service highlights her role as a versatile support vessel during a critical period in U.S. naval history, providing essential logistical support in the coastal waters of the Gulf of Mexico and demonstrating the widespread utilization of commercial ships for wartime needs.
