RedactedNarrative: The operator of Vessel 1 was traveling south on Lake Bistineau.  The passenger sitting on the from deck had been drinking (see coroner's report) and jumped from the vessel twice earlier in the day while in motion.  As Vessel 1 was traveling south and maneuvered to the starboard side, the passenger sitting on the front deck jumped out of the port side of Vessel 1, according to the witness sitting on the port side next to the operator.  PFD's were in Vessel 1 and proper size for the occupants, but none were being worn.  Vessel 1 was equipped with remote steering.  The incident occurred due to passenger behavior. The operator of Vessel 1 was found to be intoxicated.
