Wreck Location Map
Vessel Type
The J.O. THAYER was a large wooden schooner, designed primarily for hauling bulk cargo, particularly coal, across the Great Lakes. Vessels of this type were common in the late 19th century, known for their sturdy hulls and ability to transport heavy loads efficiently between industrial ports in the U.S. and Canada.
Description
Constructed in 1874 in Two Rivers, Wisconsin, the J.O. THAYER measured 154 feet in length with a 29-foot beam, making her a significant vessel for her time. She was built to withstand the rigours of the Great Lakes, transporting coal—a key resource during the industrial boom of the late 19th century.
Owned by J. Bertschy of Sheboygan, she was part of a fleet of schooners critical to the economic development of cities around Lake Michigan. Her robust construction allowed her to operate in various weather conditions, although, like many wooden vessels, she remained vulnerable to severe storms.
History
The J.O. THAYER operated during a dynamic period in Great Lakes maritime history, when schooners were gradually being replaced by steam-powered vessels. However, their cost-efficiency and versatility ensured their continued use for decades, particularly for carrying coal, lumber, grain, and other bulk commodities.
She frequently sailed between coal ports in the eastern Great Lakes and industrial hubs along Lake Michigan, including Sheboygan, Milwaukee, and Chicago. Her role in transporting coal was vital, supporting industries and railroads that relied heavily on this resource.
Significant Incidents
Final Voyage & Loss: On November 18, 1881, the J.O. THAYER encountered a severe storm while navigating near Sheboygan, Wisconsin. Battling strong winds and heavy waves, the schooner stranded on a sandy bar, sustaining heavy damage to her hull. Despite the crew’s efforts, she could not be freed, and multiple salvage attempts failed to dislodge her.
Although declared a total loss after these unsuccessful efforts, the schooner’s story didn’t end there. In 1882, she was recovered from the wreck site, reflecting the era’s determination to salvage valuable vessels. By 1883, she was fully rebuilt and renamed the MIKE CORRY, extending her life on the Great Lakes.
