In October 1960, as part of Operation Deep Freeze, she departed Boston, passed through the Panama Canal, crossed the Pacific, visited New Zealand and McMurdo sound. Leaving Antarctica, she traveled the Indian Ocean, came through the Suez Canal, crossed the Mediterranean Sea and the Atlantic Ocean to return home in May 1961. This tour made the Eastwind the first cutter ever to circumnavigate the globe. Two mountains in Antarctica, Mount Schmidtman and Mount Naab, were named after her captains during this period: Captain R.D. Schmidtman, USCG commanded the vessel in 1960, and Captain Joseph Naab, Jr., USCG commanded her during 1961 and 1962.
