It’s hard to pick a favorite freighter when there are nearly countless vessels that call the Great Lakes home and rely on the Soo Locks to haul cargo. Because traveling into Lake Superior is so important for the shipping industry, there are 13 freighters which push the envelope on how large a freighter can be. Throughout the 1970s and early 1980s, freighters measuring over 1,000 ft. were all the rage. These bulk carriers were designed with the maximum dimensions of the Poe Lock in mind. They’re so large, they can’t travel outside of the Great Lakes. We’re thankful they call the lakes home and are frequent fliers to Sault Ste. Marie.
We’ve gathered up information on all 13 of them to help you keep track of the largest freighters on the Great Lakes. Be sure to hover your cursor over the photos or to tap them on your mobile device to display each vessel’s stats.

Engine Horsepower: 14,000 bhp
The Stewart J. Cort is the one that started it all. In fact the “#1” painted on her aft house celebrates her distinction as the first 1,000 footer. By being the first 1,000 footer, “Stubby,” as she’s affectionately known was in turn briefly the Queen of the Great Lakes (the crown the largest ship on the lakes wears.) Construction for the Stewart J. Cort’s bow and stern begin in 1970 in Mississippi. She was transported up north and in 1971 she had her hull inserted. Her unusual design and method of fabrication gave her the nickname “Stubby.” Her maiden voyage was on May 1, 1972.

The Paul R. Tregurtha is the current “Queen of the Great Lakes” and the longest reigning “Queen” the Great Lakes has seen. Big Paulie as she’s affectionately known was the last of the 1,000 ft. freighters capping off a decade of ship builds the Great Lakes has never seen and may never see again. The Tregurtha was the last freighter built on the Great Lakes for nearly 30 years until her newest fleetmate, the Mark W. Barker set sail in 2022. Want to take a look at the PRT?
