IDENTIFICATION & SITE INFORMATION

VESSEL TYPE DESCRIPTION

The Thomas Wilson was a riveted-steel Whaleback freighter, a unique design conceived by Alexander McDougall. Whaleback ships featured streamlined, cylindrical hulls with rounded ends, resembling a submarine or “whale’s back.” This design minimized wind and wave resistance, making them ideal for transporting bulk cargo such as iron ore, grain, and lumber. The Wilson’s construction included advanced safety features for its time, such as hold beams, double bothttps://shotlinediving.com/wp-content/uploads/52895851813_b64678c0f7_c.jpgs, two watertight bulkheads, and a steam pump system.

HISTORY

Launch and Service:

Launched in 1892 from Lake Superior, Wisconsin, the Thomas Wilson was among the earliest Whaleback freighters, part of a fleet designed to revolutionize bulk freight shipping on the Great Lakes. Operated by the American Steel Barge Company, the vessel primarily transported industrial commodities across Lake Superior and other Great Lakes.

Significance:

The Wilson represented innovation in shipbuilding during the late 19th century, emphasizing efficiency and safety. Its distinctive design set it apart from other freighters of the era and became a hallmark of the industrial expansion of the region.

FINAL DISPOSITION

Incident:

On June 7, 1902, while departing Duluth Harbor in clear weather, the Thomas Wilson collided with the wooden Steamer George G. Hadley due to miscommunication. The Hadley failed to follow whistle signals, resulting in a collision that struck the Wilson forward of the aft hatch.

Sinking:

The impact caused the Wilson to roll to its port side, then briefly right itself before beginning to sink bow-first. The ship disappeared beneath the waves in just three minutes. Tragically, nine of the 20 crew members perished in the incident. The wreck’s speed and severity highlighted vulnerabilities even in well-built vessels.

Aftermath:

The disaster led to stricter navigation regulations in Duluth Harbor, aimed at preventing miscommunication and enhancing safety protocols.

CURRENT CONDITION & ACCESSIBILITY

Wreck Condition:

The Thomas Wilson is one of the most intact examples of a Whaleback freighter on the lakebed. The vessel’s unique Hull shape, mechanical components, and structural features remain well-preserved in Lake Superior’s cold, fresh water. The wreck is a prime example for studying 19th-century shipbuilding and Whaleback design.

Accessibility:

Resting at 70 feet (21 meters), the wreck is accessible to recreational divers with appropriate training. The clear, cold waters of Lake Superior offer good Visibility, allowing divers to observe features such as the bow, propeller, and remnants of the cargo holds.

NOTMARs & ADVISORIES

There are no active Notices to Mariners (NOTMARs) specifically associated with the Thomas Wilson wreck site. However, divers and boaters should adhere to regulations in Duluth Harbor, especially when navigating near known wreck locations.

SIGNIFICANCE OF THE WRECK

The Thomas Wilson represents the zenith of Whaleback freighter innovation and its importance in the industrial era of the Great Lakes. Its preserved state offers insights into ship design, operational hazards, and the evolution of maritime safety regulations.
