Vessel Type

The R.G. Coburn was a propeller steamer, a type of vessel equipped with a screw propulsion system, which was increasingly common for cargo and passenger transport on the Great Lakes in the late 19th century. Built in 1870, the R.G. Coburn was a relatively new vessel, specifically designed to handle the growing freight and passenger trade on Lake Superior. With a tonnage of 857, it was among the larger steamers of its class, optimized for carrying bulk goods such as wheat and flour.

Description

The R.G. Coburn embarked on its ill-fated journey from Duluth in October 1871, carrying a significant cargo of wheat and flour destined for various ports. The vessel was part of the Atlantic, Duluth, and Pacific Steamboat Line, a key player in the commercial transport network of the Great Lakes. Under the command of Captain Gilbert DeMont, the ship had become a familiar sight along its routes, reliably connecting remote ports with major trade centers.

History

On October 15, 1871, the R.G. Coburn encountered one of the fiercest gales of the year in Saginaw Bay, Lake Huron. The storm’s relentless winds and towering waves proved too much for the vessel, which lost its rudder and became unmanageable. Falling into the troughs of the waves, the steamer was battered by the elements until it succumbed to the lake’s icy grip.

Significant Incidents

• The disaster claimed the lives of approximately 45 individuals, including Captain DeMont and every officer except the second mate.
• The loss extended to the captain’s family, leaving his five children orphaned.
• A total of 18 survivors, including some passengers and crew, were rescued by the propeller Keweenaw, a sister ship in the same fleet.
• Efforts to abandon the ship were hampered by the storm’s ferocity. While the vessel was equipped with sufficient life-saving apparatus and wooden boats, the two metallic lifeboats were found unused, their occupants likely overwhelmed by the cold and waves.
• Two crew members were discovered deceased near these lifeboats, underscoring the storm’s deadly intensity.

Final Disposition

The wreck of the R.G. Coburn has not been definitively located. Debris and cargo from the ship were found along the shores near Kincardine, Ontario, but the vessel’s final resting place likely remains in the depths of Saginaw Bay.

Current Condition & Accessibility

There are no current Notices to Mariners (NOTMARs) related to the wreck of the R.G. Coburn. However, mariners should remain cautious when navigating in Saginaw Bay due to its history of shipwrecks and challenging weather conditions.
