Wind-class icebreakers had hulls of unprecedented strength and structural integrity, with a relatively short length in proportion to the great power developed, a cut away forefoot, rounded bottom, and fore, aft and side heeling tanks.
She became the first icebreaker to make a narcotics seizure and broke the previous tonnage record set by USCGC Sherman. This was a marijuana seizure record (for an icebreaker) that stands as of 2015.

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.
