When you reach Pringle Rock, you find a 5-metre runabout floating and not taking on water, but with a severely damaged outboard drive unit and propeller. The

operator, though unhurt, is very upset with himself for not exercising more care in his navigation. You fashion a towing bridle and begin the tow back to his cabin at

Roscoe Bay.
