The SS Erna was an 865 gross register tonnage (GRT) coaster constructed in 1922 by Howaldtswerke in Kiel, Germany. Designed for coastal trade, she measured 194 feet 6 inches (59.28 meters) in length, with a beam of 32 feet 9 inches (9.98 meters) and a depth of 13 feet 9 inches (4.19 meters). Her propulsion was provided by a triple expansion steam engine, featuring cylinders of 13 3/8 inches (34 cm), 23 1/4 inches (59 cm), and 38 3/16 inches (97 cm) in diameter, with a stroke of 25 3/5 inches (65 cm). The engine was also built by Howaldtswerke, enabling her to navigate the coastal waters efficiently. Initially owned by H. A. Petersen of Flensburg, Erna was the last vessel operated by that company. She was sold in 1930 to Ernst Russ of Hamburg, where she registered under the port of Hamburg with the code letters LNRK. Throughout her service life, Erna experienced notable incidents, including a collision with the German submarine U-738 off Gotenhafen (now Gdynia, Poland) in February 1944, which resulted in the sinking of U-738 and the loss of 22 crew members. In March 1945, she was also damaged by fire during an air raid. Following the end of World War II, in July 1946, Erna was seized by Allied forces at Kristiansand, Norway, and passed to the UK Ministry of Transport, receiving the new name Empire Conforth. She was subsequently sold to Cyprus Ship Management Co. in 1947 and renamed Troödos. Her ownership changed multiple times thereafter, with her name changing to Burica (1952), Dmitris (1953), and Cedar (1955), reflecting her various owners in Costa Rica and Panama. Her service continued until 1958, when she was scrapped in Hong Kong, marking the end of her maritime career. The SS Erna's history illustrates her role as a versatile coastal vessel through the interwar and postwar periods, witnessing significant wartime events and changes in ownership.
