The USS Wanderer (SP-132) was an armed yacht that served in the United States Navy from 1917 to 1919, originally built in 1897 as the private steam yacht Kethailes in Leith, Scotland, by Ramage & Ferguson. Designed as a gentleman’s private vessel, she was constructed for William Johnston, a wealthy shipowner. In 1903, she was sold to H. A. C. Taylor of New York City, who renamed her Wanderer. The Navy acquired her on June 10, 1917, for World War I service, and she was commissioned as USS Wanderer (SP-132) on July 14, 1917. A relatively small vessel, Wanderer was tasked primarily with antisubmarine patrol and coastal convoy escort duties along the north Bay of Biscay coast, operating from Brest, France. Her design as a pleasure craft made her less robust than warships, posing risks from mines, weather, and rocky shores rather than from U-boat attacks. Her early service included convoy routes from Brest to Quiberon Bay and further south to Bordeaux, with her duties often complicated by severe weather conditions. Notably, Wanderer played a significant role in the evolution of convoy tactics. Initially supporting night convoys—an approach that proved perilous—she participated in the first daylight convoy escort in January 1918, which successfully demonstrated the advantages of daylight operations supported by aircraft and ships. During her service, she rescued 10 survivors from the French ship Chateau Faite after a U-boat attack and witnessed the explosion of the ammunition-laden Florence H. in Quiberon Bay, though she could not assist directly due to her own cargo of high explosives. Wanderer remained on patrol and escort duty along the French coast until the end of the war, with no further notable enemy encounters. She departed Brest on December 5, 1918, returning to the United States by December 30, and was decommissioned in April 1919. She was sold in July 1920 to J. S. Webster of Baltimore. Her service exemplifies the transitional role of private yachts adapted for wartime patrol and convoy escort duties during World War I, contributing to the Allied effort in safeguarding maritime traffic against U-boat threats.
