USCGC BRISTOL BAY (WTGB-102)

 

The 140-foot Bay class Cutters are state of that art icebreakers used primarily for domestic ice breaking duties. They are named after American Bays and are stationed mainly in the northeast United States and the Great Lakes.

WTGBs use a low pressure air hull lubrication or bubbler system that forces air and water between the hull and ice. This system improves icebreaking capabilities by reducing resistance against the hull, reducing horsepower requirements.
