In the year 1950, "Acushnet" became active in the International Ice Patrol and spent a total of seven patrol months sharing that responsibility with the cutters "Androscoggin" and "Evergreen". "Acushnet"s salvage gear was removed in late 1959 and replaced with search-and-rescue gear. From 1960 to 1968 "Acushnet" completed four towing missions for over , assisted a vessel that broke in two, escorted four disabled vessels and assisted in two medevacs. A few of "Acushnet"s more noteworthy cases during that time frame include the following: in 1960, it salvaged the 300-ton USCGC "General Greene" which had been driven one hundred yards ashore in high winds. One of her more dramatic cases in Portland included the rescue of the entire crew of ten people from the disabled seagoing dredge "Cartagena", which was adrift in seas and winds off of Cape Cod on Christmas Day, 1961. In May 1963, "Acushnet" salvaged a crashed Coast Guard helicopter off Duxbury Beach, Massachusetts.
