The USS Carola IV was originally constructed in 1885 by the Culzean Shipbuilding & Engineering Company in Maidens, South Ayrshire, Scotland. Initially launched as the steam yacht Black Pearl, she was built for the Earl of Pembroke & Montgomery. The vessel's design as a yacht indicates a refined, luxury-oriented build, though specific dimensions and technical specifications are not provided in the source. Throughout her early years, the vessel changed ownership multiple times. In 1895, she was sold to E. B. Sheldon of Chicago, Illinois, and in 1900, she was purchased by Evans R. Dick of Philadelphia, Pennsylvania, who renamed her Elsa. The yacht later bore the names Haida and Columbine during her service life. By mid-1910, she was owned by Leonard Richards of New York City, who served as the Commodore of the Larchmont Yacht Club, reflecting her continued use as a private yacht. In June 1917, amidst World War I, the vessel was acquired by the United States Navy for patrol duties. She was commissioned as USS Carola IV in early July 1917. Her service included crossing the Atlantic Ocean via Newfoundland and the Azores to reach Brest, France, where she conducted patrol operations along the French coast. However, in October 1917, she was deemed unseaworthy and was consequently relegated to harbor service as an accommodation vessel. She remained in this capacity through the end of the war and for an additional year afterward. USS Carola IV was decommissioned in late December 1919 and subsequently sold to a Brest buyer. She remained in existence until she was broken up in 1957. Her service history reflects a common pattern of private yachts repurposed for wartime patrol duties during WWI, though her operational effectiveness was limited by her condition, leading to her relegation to harbor service.
