Interlake Steamship Company

When Interlake launched its largest vessel, MV William J. Delancey (now MV Paul R. Tregurtha), its fleet contained 151 vessels, and was capable of carrying over three million tons of cargo at one time.

The Barker and Tregurtha families, owners of Interlake Steamship, chartered the 418-foot (127 m), 14,000 short tons (13,000 t) barge Montville to provide this new service on an as-needed basis.

[7] In April 2019, Interlake Steamship announced construction of a 639-foot (195 m) long, 75-foot (23 m) wide River-class self-unloading bulk freighter.

[9] The ship was christened MV Mark W. Barker in Cleveland, Ohio[8] on 1 September 2022.

[10] In December 2020, SS Badger was acquired by the Interlake Steamship Company.
