USCG Bay Class Icebreaking Tug
The USCG Bay-class icebreaking tug is a class of 140-foot (43 m) icebreaking tugs of the United States Coast Guard, with hull numbers WTGB 101 through to WTGB 109.
They can proceed through fresh water ice up to 20 inches (51 cm) thick, and break ice up to 3 feet (0.91 m) thick, through ramming. These vessels are equipped with a system to lubricate their progress through the ice, by bubbling air through the hull.

Famous quotes containing the words bay, class and/or tug:
“The very dogs that sullenly bay the moon from farm-yards in these nights excite more heroism in our breasts than all the civil exhortations or war sermons of the age.”
—Henry David Thoreau (1817–1862)
“We of the sinking middle class ... may sink without further struggles into the working class where we belong, and probably when we get there it will not be so dreadful as we feared, for, after all, we have nothing to lose but our aitches.”
—George Orwell (1903–1950)
“What exacerbates the strain in the working class is the absence of money to pay for services they need, economic insecurity, poor daycare, and lack of dignity and boredom in each partner’s job. What exacerbates it in upper-middle class is the instability of paid help and the enormous demands of the career system in which both partners become willing believers. But the tug between traditional and egalitarian models of marriage runs from top to bottom of the class ladder.”
—Arlie Hochschild (20th century)
