RedactedNarrative: Vessel 1 was launched just upriver from the point of the accident.  As Vessel 1 travelled under the bridge, the bow end of Vessel 1 went down and into an eddy, swamping Vessel 1.  Vessel 1 then capsized, ejecting both Occupants aboard Vessel 1 into the water.  Initially, both Occupants were able to grab Vessel 1 and float downstream; however, the Victim then lost their grip and slipped off of Vessel 1.  The other Occupant then grabbed the Victim and swam both of them to shore.  Upon reaching the shore, the Victim was unresponsive and CPR was started.  The Victim was later pronounced deceased.
