Presque Isle

At Port Huron, with Sarnia across the way.

Presque Isle is technically a barge with a tug tucked into her stern, but both have the same name and they've rarely been separated and have always operated as a single ship. In fact, they're so effectively a single ship that the Coast Guard didn't buy Litton Industry's argument that the combination justified the (lower) staffing levels required for tug-barge operations, so she carries a full crew. Now operating as part of the CN Great Lakes fleet, but for many years she was the only ship on the Lakes wearing Litton colors on her stack.
