SS Edmund Fitzgerald (nicknamed "Mighty Fitz," "The Fitz," or "The Big Fitz") was an American Great Lakes freighter launched on June 8, 1958. At the time of its launching, it was one of the first boats to be at or near maximum "St Lawrence Seaway Size" which was 730 feet (220 m) long and 75 feet (23 m) wide. From its launching in 1958 until 1971 the Fitzgerald continued to be one of the largest boats on the Great Lakes.
On November 10, 1975, while traveling on Lake Superior during a gale, the Fitzgerald sank suddenly in Canadian waters approximately 17 miles (15 nmi; 27 km) from the entrance of Whitefish Bay at a depth of 530 feet (160 m). Although it had reported having some difficulties before the accident, the Fitzgerald sank without sending any distress signals. Its crew of 29 perished in the sinking with no bodies being recovered. When the wreck was found, it was discovered that the Fitzgerald had broken in two.
The sinking of the Edmund Fitzgerald is the most famous disaster in the history of Great Lakes shipping. The disaster was the subject of Gordon Lightfoot's 1976 hit song, "The Wreck of the Edmund Fitzgerald.
