About STR Edward L Ryerson
SS Edward L. Ryerson is a steel-hulled American Great Lakes freighter that entered service in 1960. Built between April 1959 and January 1960 for the Inland Steel Company, she was the third of the thirteen so-called 730-class of lake freighters, each of which shared the unofficial title of "Queen of the Lakes", as a result of their record-breaking length. She was not only the last steam-powered freighter built on the lakes but also the last one that was not a self-unloader. She is one of only two American-owned straight deck lake freighters, the other being John Sherwin, built in 1958. Built to transport iron ore almost exclusively, Edward L. Ryerson completed her sea trials on August 3, 1960. She then travelled to Escanaba, Michigan, where she loaded a cargo of iron ore, embarking on her maiden voyage for Indiana Harbor, Indiana, on August 4.
