RedactedNarrative: victim was swimming in a westerly direction heading into Bourne Cove. Operator was at headway speed in the same direction. This Cove is a narrow channel (approx. 100 feet wide and it is difficult to navigate due to rocks). Operator felt a bump underneath the boat but thought he hit rocks. Operator looked aft and saw the victim in distress. It is most likely he saved her life. This area in not a designated swimming area nor was the vessel being operating in an unsafe manner.
