The SS Sylvania was a notable Great Lakes freighter measuring 572 feet in length after a 1957-1958 lengthening, which increased her from an original 524 feet. Built by the West Bay City Shipbuilding Company of West Bay City, Michigan, she was designated as hull #613 and initially operated for the Duluth Steamship Company of Duluth, Minnesota. Throughout her extensive 79-year career, the Sylvania was involved in multiple accidents, reflecting the challenging conditions of Great Lakes shipping. Her first recorded incident occurred on June 12, 1905, when she collided with the steamer Sir Henry Bessemer at Whitefish Point, Lake Superior, due to confused passing signals. She experienced several other collisions: with the John W. Gates at Duluth in 1916, with the Belgium off Whitefish Point in 1918 during fog, with the Orlando M. Poe in the Detroit River in 1922, and with the Conneaut airport beacon leading to her grounding on Lake Erie in 1929. Notably, in 1929, her name was temporarily changed to D.M. Philbin before reverting to Sylvania in 1929. The vessel underwent significant modifications in 1957-1958, including lengthening by 48 feet and conversion into a self-unloader, enhancing its cargo handling capabilities. In 1954, she was acquired by the Tomlinson Fleet Corporation. She continued to serve until her final years, marked by several more incidents, such as a collision with the Renvoyle in 1967, a collision with the Diamond Alkali in 1968, and multiple groundings and mechanical issues in the early 1970s. Her service concluded after her last voyage on May 10, 1980. She was laid up in Toledo, Ohio, and later towed to Ashtabula, Ohio, in 1983, marking the end of her long and eventful career on the Great Lakes. The SS Sylvania remains a significant example of early 20th-century Great Lakes freighter design and operation, reflecting the complexities and hazards of maritime commerce in the region.
