"Acacia" also participated in numerous search and rescue missions. In October 1951, the freighter "George F. Rand" collided with another ship in the Saint Claire River. Her hull was breached and she began to flood. "Acacia" was dispatched to provide assistance which included emergency pumps to control the flooding. On June 1, 1956 "Acacia" towed the disabled freighter "George Hindman" from the Saint Claire River where she was blocking ship traffic. The freighter "Daniel J. Morrell" broke up and sank in a storm on Lake Huron in November 1964. "Acacia" was dispatched to search for the crew and recovered the bodies of eight. A happier outcome was obtained after two freighters collided at the mouth of the Saint Claire River during the night of August 26, 1971. "Acacia" was able to rescue 16 people from "Trans Michigan".
