RedactedNarrative: Boat A was drifting while both occupants were fishing near the hay creek narrows on the Chippewa Flowage.  Boat B was in transit and the operator was looking at his depth finder and not paying attention to surroundings.  As Boat B was getting closer to Boat A the occupants of Boat A began to yell at Boat B as they were getting closer to and were trying to prevent colliding with them.  The operator of Boat B finally heard the screams and swerved to miss Boat A but struck the skeg of the trolling motor that was on the bow causing damage to both boats.
