J. L. Mauthe

Upon conversion into a barge, it was renamed as Pathfinder and is currently active on the lakes as an articulated tug-barge unit, paired with the Z-drive tug Dorothy Ann with a home port of Cleveland, Ohio.

Mauthe is one of the eight AAA class American ships, originally built with a length of 647 ft (197.2 m) in the 1950s.

Mauthe, are still operational today, making the AAA class one of the most successful designs on the Great Lakes.

[6] Having sustained damage and wear through the progression of years, the vessel fell behind other AAA class ships[3] and was put into layup in 1993.

[5] Pathfinder was coupled with the pusher tug MT Joyce L. VanEnkevort from 1998 to 1999,[7] until the Interlake Steamship Company built their new Z-drive tug, called the MT Dorothy Ann, which has sailed with Pathfinder as a tug-barge unit.
