The USS Merak (AF-21) was a Mizar-class stores ship that served in the United States Navy during World War II, originally built as the United Fruit Company cargo and passenger liner Veragua. Constructed by Bethlehem Shipbuilding Corporation at Quincy, Massachusetts, Veragua was launched on April 23, 1932, and delivered in August of the same year. The vessel measured approximately 447 feet in length, with a beam of 60 feet, and a draft of around 24 feet. It displaced about 10,928 tons at the designed waterline and had a gross tonnage of approximately 7,035. The ship featured a turbo-electric propulsion system, generating 10,500 horsepower, which allowed for a service speed of 17.5 knots, with some trials reaching up to 19 knots. Designed primarily for refrigerated banana transport, Veragua was part of a fleet of six nearly identical ships built for the United Mail Steamship Company, a subsidiary of United Fruit. Its extensive refrigerated cargo holds—16 compartments—enabled it to carry bananas and other perishable goods, alongside passenger and mail services. The ship’s design incorporated the "two compartment" rule for safety, with multiple watertight bulkheads subdividing the hull into nine compartments, enhancing survivability. In wartime, Veragua was delivered to the War Shipping Administration and transferred to the Navy, commissioned as USS Merak (AF-21) on May 8, 1942. During its service, Merak operated primarily in the Atlantic, conducting convoy duties, transporting supplies, and supporting Allied operations across Europe and North Africa. Notably, Merak made transatlantic crossings to locations such as Algeria, Sicily, Scotland, and Reykjavík, Iceland. After the war, she was decommissioned in June 1946, returned to the WSA, and resumed commercial service under her original name. In 1958, the ship was transferred to the British subsidiary Elders and Fyffes and renamed SS Sinaloa. She continued operating until she was scrapped in Ghent, Belgium, in 1965. The vessel’s maritime significance lies in its dual role as a commercial banana ship and wartime auxiliary, exemplifying the adaptability and strategic importance of refrigerated cargo ships during the mid-20th century.
