RedactedNarrative: Operator and passenger left the boat launch at a high rate of speed. At some point, for unknown reason, the boat took a hard left turn. Both occupants ended up in the water without lifejackets. Another boater tried to rescue them, but they both went under and did not resurface. A search was started and the operator's body was recovered at about 1900 hours the same day. The passenger's body was recovered at about 1600 hours the following day. There was no mechanical equipment failure found. Life jackets were on board, but were not being worn. Alcohol was not a factor. There was a small amount of damage to the boat.
