Glacier in 1956.. Glacier was essentially an improved Wind-class icebreaker, larger and more powerful.Like them, her entire hull was designed for great strength. With a relatively short length in proportion to the great power developed, her bow had the characteristic sloping forefoot that enabled her to ride up on heavy ice and break it with the weight of the vessel.
This is a list of icebreakers and other special icebreaking vessels (except cargo ships and tankers) capable of operating independently in ice-covered waters. Ships known to be in service are presented in bold .
Icebreakers are often described as ships that drive their sloping bows onto the ice and break it under the weight of the ship. [23] In reality, this only happens in very thick ice where the icebreaker will proceed at walking pace or may even have to repeatedly back down several ship lengths and ram the ice pack at full power.
Westwind was one of the icebreakers designed by Lieutenant commander Edward Thiele and Gibbs & Cox of New York, who modeled them after plans for European icebreakers he obtained before the start of World War II. [1] She was the fourth of seven completed ships of the Wind class of icebreakers operated by the United States Coast Guard.
USCGC Eastwind (WAGB-279) was a Wind-class icebreaker that was built for the United States Coast Guard. Completed in time to see action in World War II, she continued in USCG service under the same name until decommissioned in 1968.
The Canadian Coast Guard designates the four ships in the class as medium icebreakers.

The fourth, Henry Larsen was built to a modified design and is considered a subclass, the Improved R-class icebreaker.
