VESSEL TYPE DESCRIPTION

The Emma E. Thompson was a wooden bulk freighter with a single mast and Screw Propulsion. Built in 1875, the vessel was optimized for carrying heavy cargo, especially lumber, across the Great Lakes. Its design and high-pressure engine allowed it to meet the rigorous demands of 19th-century shipping. Over its operational life, it underwent modifications, including temporary Conversion into a Schooner before reverting to a screw Steamer.

HISTORY

Launched in April 1875, the Emma E. Thompson had a storied operational life marked by resilience and misfortune. Despite early setbacks, including grounding incidents and a boiler explosion, the vessel remained in service for nearly four decades, navigating the challenging waters of the Great Lakes.

Key Incidents:

  • 1875: Boiler explosion and grounding during its first year.
  • 1880s: Multiple ownership changes and a collision with the Schooner Kate Lyons.
  • 1881: Rebuilt and remeasured, continuing service on the Chicago–Muskegon route.
  • 1901: Capsized near Charlevoix, Michigan; the vessel was salvaged and returned to service.

Final Voyage:

On May 24, 1914, while seeking shelter behind Innes Island in the North Channel of Lake Huron, the Emma E. Thompson caught fire. The blaze, possibly ignited by an engine room mishap, engulfed the vessel. The crew was rescued by the passing propeller vessel Germanic. Despite the rescue, the ship burned to the waterline and sank. The wreck now rests at a depth of 22 feet near Innes Island.

FINAL DISPOSITION

The Emma E. Thompson was lost to fire on May 24, 1914. The wreck lies in 22 feet of water in the North Channel of Lake Huron, near Innes Island. Burned to the waterline, the remaining structure serves as an accessible site for divers and a historical point of interest.
