About SS William G. Mather

The SS William G. Mather was a 533-foot (162 m) long Great Lakes freighter that was built in 1905, by the Great Lakes Engineering Works (GLEW) of Ecorse, Michigan, for the Grand Island Steamship Company (managed by Cleveland-Cliffs Iron Company). Her keel was laid on May 18, 1905. She was launched on September 23, 1905, as hull #9. The ship was named after William G. Mather, the Cleveland-Cliffs executive. She was powered by a 2,000-horsepower (1,500 kW) triple expansion steam engine which was attached to a single fixed-pitch propeller. She was fueled by two coal-fired Scotch marine boilers. She entered service in January 1905, and was the first Great Lakes freighter with a 60-foot (18 m) beam.
