Her next Antarctic trip came during the winter (Antarctic summer) of 1960-1961 as a member of Operation Deep Freeze 61. While operating far south of New Zealand in an attempt to salvage a naval vessel that had broken loose from its moorings, "Edisto" encountered what was probably the worst storm of her career. With tons of ice loading her topside down, she staggered to regain stability at the end of each long, agonizing roll. Before the storm had blown itself out, "Edisto" had lost most of her rigging and her starboard propeller.
