The Katamai Bay is at work breaking ice in the Straits of Mackinaw on March 6, 1992

The 140-foot Bay-class Cutters are used primarily for domestic ice breaking duties in the Northeast U.S. and Great Lakes. They are usually named after Bays along the United States coastline.

Using a low-pressure-air hull lubrication or bubbler system that forces air and water between the hull and ice reducing resistance. This system reduces horsepower requirements and dramatically improves icebreaking capabilities. The Cutter is designed to break 20 inches of hard, freshwater ice continuously with a "backing and ramming" thickness of more than 3 feet.

These state of the art icebreakers also perform Law Enforcement, Environmental Protection, Search & Rescue operations and support for Aids to Navigation Activities.

When working Aids to Navigation Activities, the vessels works with a 120 foot barge which carries a lift system along with the aids and their anchor systems.
