RedactedNarrative: Vessel 1 was with a group of canoeists serving as the “safe” boat.  They would scout ahead and report back to the canoeists what was coming up.  Vessel 1 was heading upstream and had just reported to the canoeists the distance to their landing. Vessel 1 was making a sharp right turn to return downstream when the Passenger, who was seated on the front bench seat facing toward the stern, re-positioned his weight.  This shift caused the vessel, which was already in a turn, to heel on its starboard side.  Vessel 1 Operator fell out of the vessel followed by the Passenger.  The tiller motor was still in gear and propelled the vessel in a circular fashion.  Both the operator and the passenger swam toward the vessel.  When the vessel was close to the operator he realized he could not grab the boat and pushed it away.  The passenger, who was a short distance away, was hit in the head by the side of the vessel.  The motor cut out around that time.  The Passenger was hit by the motor area of the vessel as well.  The canoeists returned to assist; the Passenger was floated to shore on PFDs and the vessel was walked to shore.
