crack of the traditional bottle of champagne, Interlake's new tug Dorothy Ann was
christened at a ceremony in Cleveland at the Cleveland-Cuyahoga County Port Authority on
Monday, June 28, 1999.
Susan Tregurtha Marshall, daughter of Paul R.
Tregurtha, successfully broke the bottle on the tug's hull with one swing. Shortly after
April S. Barker repeated the task for the barge Pathfinder.
The tug and barge completed their first trip together in late June carrying a load of
taconite from Escanaba, Michigan to Huron, Ohio.
Dorothy Ann is the largest Z-drive tug built to date in North America. Her twin Ulstein
Z-drives enable her to turn on her own axis, stop within her own length, and move easily
in any direction. Coupled with barge Pathfinder, the pair is the most maneuverable unit on
the Great Lakes. Alone, Dorothy Ann can travel at 16 MPH: when pushing the loaded barge,
open lake speed is 11.5 MPH. She is fitted with a Great Lakes-specific articulated
pin-type connection system for engaging Pathfinder's notched stern. Dorothy Ann's elevated
pilot house - outfitted with state-of-the-art navigation and communication equipment - has
a height of eye of 70 feet, and the vented tower was designed to spoil trailing air
drafts. Accommodations include air-conditioned private cabins with semi-private bathroom
facilities for 12 crew members, a lounge, and an owner's stateroom.
Namesake of tug Dorothy Ann is Dorothy Ann Tregurtha
Croskey of Minneapolis, MN. "Dory" is the daughter of Paul R. Tregurtha,
vice-chairman of the Interlake Steamship Company.
We salute the Interlake Steamship Company and welcome the tug Dorothy Ann, may she and the
Pathfinder have a long and successful career on the Lakes.
