USCGC Eastwind (WAGB-279) Antarctic, Operation Deep Freeze. A close-up shows how the reinforced bow of the 6,515-ton U. S. Coast Guard icebreaker Eastwind rides up onto a thick ice lodge in crystal-paved McMurdo Sound and lets the fall of her weight break the ice. Two stern propellers delivering 10,000 horsepower at full speed for her climb. The ice may be 7 to 15 feet or more in depth. Some times the surface friction causes the bow to stick fast to the ice. So that the icebreaker may cut loose and back down off the ledge in that case, her system of heeling tanks is set in motion. Thousands of

So that the icebreaker may cut loose and back down off the ledge in that case, her system of heeling tanks is set in motion. Thousands of gallons of water are pumped into huge tanks on both sides of the ship. The swishing of water back and forth from the tanks produce a rocking motion which frees the ship.
