"Location": USNS Southern Cross at sea. "Date": circa 1981-1983 "Photographer": Randy C. Bunney The ship's bosun, an able seaman (AB) day worker, and a watchstander AB are seen here working aloft to maintain cargo rigging. The seamen are seated in bosun's chairs, each of which has a bucket of grease attached. The seamen use the grease to "slush" the wire ropes in the freighter's running tackle to help protect from corrosion. The grease also facilitates smooth operation of the wire rope as it passes through blocks and deck winches.
