The SS Regina was a cargo ship built for the Merchant Mutual Line and home ported in Montreal, Quebec. Named after Regina, Saskatchewan, Regina had a tonnage of 1,956 gross register tons (GRT) and a crew of 32. The ship sank during the Great Lakes Storm of 1913 after taking great damage. Lost for more than a half century, she became known as the "Great Mystery of the Great Storm of the Great Lakes". Since found, she has become an active dive site for scuba divers and is now part of Michigan's underwater Preserve system.
