The SS Marietta was a cargo vessel originally constructed in 1943 under the name Empire Daring by William Hamilton & Co Ltd in Port Glasgow, United Kingdom. With a gross register tonnage (GRT) of 7,059 and a net register tonnage (NRT) of 4,801, she measured 423 feet 4 inches (129.03 meters) in length and had a beam of 56 feet 2 inches (17.12 meters). Her depth was 34 feet 2 inches (10.41 meters), and her draught was 26 feet 6 inches (8.08 meters). Propelled by a triple-expansion steam engine with cylinders measuring 24½ inches, 39 inches, and 70 inches in diameter, and a 48-inch stroke, the engine was built by D Rowan & Co Ltd in Glasgow, providing her with reliable steam power for her wartime service. Commissioned for the Ministry of War Transport (MoWT), she was assigned the UK Official Number 169506 and the Code Letters BFJR, with Greenock as her port of registry. Her management was initially under J Morrison & Co Ltd. Empire Daring's maiden voyage commenced on 23 August 1943 from the Clyde, and she quickly became active in wartime convoy operations, including joining Convoy OS 55, which departed from Liverpool in September 1943. She carried stores, vehicles, and armaments, and was equipped with anti-torpedo nets, underscoring her role in maritime logistics during WWII. Throughout her service, Empire Daring operated extensively in the Mediterranean and European waters, participating in critical convoy operations such as the delivery of armaments for Operation Overlord and supporting Allied efforts around North Africa, Italy, and the Netherlands. She was present in Antwerp at the end of the war and suffered the loss of one crew member in April 1945. After the war, she continued service with various convoy runs, including voyages to Southend, Hull, Rotterdam, and the United States. In 1946, she was sold into merchant service and renamed Marietta, operated by various shipping companies until her scrapping in 1959 in Split, Yugoslavia. Her career highlights include her significant contribution to wartime logistics and her post-war service until she was retired and dismantled, exemplifying the vital role of cargo ships like her during and after WWII.
