The USS Patriot (PYc-47), originally built as Katoura in 1930 by the Herreshoff Manufacturing Company in Bristol, Rhode Island, is a notable example of a small coastal patrol vessel from the early 20th century. The ship was purchased by the United States Navy for a nominal fee of just one dollar from A. Loomis of New York City on September 20, 1940. Following acquisition, she was converted into a submarine chaser at the Greenport Basin and Construction Company in Greenport, New York, and was designated PC–455 on November 4, 1940. She was placed in service on February 27, 1941. During her naval service, PC–455 was assigned to the 1st Naval District, operating out of Boston, Massachusetts. Her primary duties involved coastal patrols along the northeastern United States, a vital role during the early years of World War II when coastal defense was paramount. On March 1, 1941, she was renamed Patriot and redesignated PYc–47, reflecting her classification as a coastal patrol craft. She continued her patrol duties throughout the war, maintaining vigilance along the U.S. coast until she was placed out of service on September 28, 1944. Following her decommissioning, USS Patriot was laid up in Quincy, Massachusetts, pending transfer to the Maritime Commission. She was struck from the Naval Vessel Register on October 14, 1944, and eventually transferred to the War Shipping Administration on March 14, 1945. Remarkably, she was sold back to her original owner for the initial purchase price of one dollar, marking a full circle in her service life. The USS Patriot (PYc-47) exemplifies the wartime utilization of civilian vessels converted for military purposes, serving crucial coastal patrol functions during World War II. Her history underscores the importance of small craft in national defense and maritime security during a critical period in history.
