The 700’2” self-unloading, articulated tug-barge unit Dorothy Ann-Pathfinder entered into service after conversion from the former straight-deck bulk carrier, Steamer J. L. Mauthe. The Mauthe was built for the Interlake Steamship Company in 1953. The 7200-horsepower, Z-drive tug Dorothy Ann was built by Bay Shipbuilding Co., Sturgeon Bay, Wisconsin, and began sailing with the barge Pathfinder in 1999.
