The USS St. Sebastian (SP-470) was a United States Navy patrol vessel that served from 1917 to 1919, primarily operating along Florida waters during World War I. Originally constructed as a private motorboat, St. Sebastian was built by Captain R. D. Hardee at St. Sebastian, Florida. The vessel was owned by J. W. Taylor of Marathon, Florida, before the Navy acquired her on June 25, 1917, to fulfill wartime patrol duties. Commissioned as USS St. Sebastian (SP-470) on August 9, 1917, the vessel was designated for section patrol duties. The ship’s specifications are not detailed in the provided content, but her role as a patrol boat involved safeguarding Florida's coastal waters during the wartime period. For the duration of her service, she conducted patrols along the Florida coast, contributing to the maritime security efforts during World War I. St. Sebastian remained in active service into early 1919, after which she was out of commission and awaiting sale. Her service was ultimately cut short when she was destroyed by the Florida Keys Hurricane on September 9, 1919, at Key West, Florida. The destruction of the vessel was part of a broader event that affected several section patrol boats during the hurricane. There is some ambiguity regarding her official removal from the Navy List, with sources indicating either her being stricken in April 1919 before her destruction or in October 1919 after the hurricane. In summary, USS St. Sebastian (SP-470) was a private motorboat pressed into naval service during World War I, serving as a patrol vessel along Florida’s coast. Her operational history was marked by her wartime patrols and her tragic destruction during a major hurricane, highlighting the vulnerabilities faced by vessels operating in coastal and hurricane-prone regions during that era.
