The Bay-class tugboat is a class of 140-foot (43 m) icebreaking tugboats of the United States Coast Guard, with hull numbers WTGB-101 through to WTGB-109.
They can proceed through freshwater ice up to 20 inches (51 cm) thick, and break ice up to 3 feet (0.91 m) thick, through ramming. They can also ram pressure ridges of up to 8 feet in thickness. These vessels are equipped with a system to lubricate their progress through the ice, by bubbling air through the hull.
