the equipment mounted aft. Since then all self-unloading equipment has been mounted aft. Algoisle (formerly Silver Isle) (1962 – ) was the first modern laker built with all cabins aft (a "stern-ender"), following the lead of ocean-going bulk carriers and reprising a century old form used by little river steam barges and the whalebacks. Stewart J. Cort (1971) was the first 1,000-footer and the only "footer" built in the classic cabins-fore-and-aft style. (1974–2015 ) was the last laker built in the classic style. Also of note is the steamer , widely known for her artistic design and being the only remaining straight-decked (without self unloading machinery) freighter still in active service on the US side of the Great Lakes (the only other US straight decker still listed is John Sherwin, has not sailed since 1981 and is currently docked in Detour, Michigan after conversion to a self-unloader and repowering was halted in November 2008). In the summer of 2006, Edward L. Ryerson was fitted out and put into service following a long-term lay-up that began in 1998. Edward L. Ryerson was often used as a museum boat for tours. She was put back into service because of a lack of reliable hulls on the lakes, and a need for more tonnage. (The Canadian fleet retains a number of active straight-deckers for use in transporting grain, which is not well suited for self-unloading equipment. Most US grain is currently transported by rail.) Serving as the setting of the movie version of David Mamet's play Lakeboat, the Canadian straight decker Seaway Queen, formerly owned by Upper Lakes Shipping and since scrapped (see below), temporarily flew a U.S. flag and displayed Chicago as her homeport for some shots. Museum ships and boats, surviving hulls Cleveland, Ohio , a laker built in 1925 and a former flagship for the Cleveland-Cliffs Iron Company, has been turned into a maritime museum and is open to the public in Cleveland in the North Coast Harbor. Duluth-Superior, Minnesota-Wisconsin was named for the president of U.S. Steel at the time of her launching and served as the flagship of US Steel's Great Lakes fleet from her launch in 1938 to 1975. She was the first laker to incorporate welding in its design and is open for tours at the Great Lakes Floating Maritime Museum in Duluth, Minnesota. Another museum ship, , is the last surviving ship of the whaleback
