Vessel Type Description

The Puritan was a steel-hulled propeller-driven vessel with three decks and four watertight bulkheads, designed for passenger and cargo transport. Initially constructed as Ottawa, it was later outfitted with 60 staterooms and modernized to operate as both a transport and luxury cruise ship. The ship served various routes on the Great Lakes and was known for its robust design, accommodating both practical utility and passenger comfort.

Construction & Early Career (1901–1908)

Built in 1901 by the Craig Ship Building Company, the vessel was initially intended to serve as Ottawa for the Chicago Steamship Company but was sold before completion. As Puritan, it operated on key routes between Chicago, Michigan ports, and the Upper Peninsula.

  • 1902: Addition of 60 staterooms, enhancing passenger accommodations.
  • 1905: Reboilered for better efficiency, followed by lengthening in 1908, increasing its capacity and tonnage.

Later Career & U.S. Navy Service (1918–1931)

During World War I, the Puritan was transferred to the U.S. Navy in April 1918 but was never deployed as a troop transport. After the war, it returned to commercial service with various owners, including the Chicago, Racine & Milwaukee Line and Michigan Transit Company. During the 1920s, it was used for overnight cruises, offering a mix of transportation and leisure.

Challenges & Ownership Changes (1927–1933) Struggling during the Great Depression, the Puritan became idle in 1931. In May 1933, it was sold to the Isle Royale Transit Company, remodeled, and renamed George M. Cox, intended for a new route to Lake Superior.

Final Voyage (May 27, 1933)

On its maiden voyage as the George M. Cox, the vessel ran aground on Rock of Ages Reef near Isle Royale. Despite salvage attempts, the ship broke apart over time, its remains scattered by weather and rough waters.

Current Condition & Accessibility

The wreck of the George M. Cox lies at a depth ranging from 40 to 100 feet, making it accessible to divers of varying experience levels. The site contains remnants of the vessel’s machinery, equipment, propeller, and steel plates, offering a glimpse into early 20th-century shipbuilding and maritime history. The wreck’s proximity to the Rock of Ages Lighthouse adds to its historical and diving appeal.
