RedactedNarrative: The Operator departed from Bonnabel boat launch at approximately 1:30-2:00pm, driving westerly approximately 2 miles north of the south shoreline. The motor of Vessel 1(LA-1479-GB) lost power and could not be restarted despite multiple failed attempts.  The operator called 911 and explained that he was drifting towards the rocks on the south shore. Investigators confirmed his 911 call was made at approximately 4:17pm. Jefferson Parish emergency operators dispatched deputies to the location and notified USCG. LDWF agents in the area witnessed the USCG helicopter circling and responded. Vessel 1 had already made contact with the rock laden shore at approximately 5:05pm and the operator had exited the vessel and swam to safety. The vessel became grounded upon the rocks and sustained significant hull damage as a result of the repetitive wave action. No injuries/fatalities occurred. Vessel 1 was recovered later that night by Moon's Towing Service. The majority of damage appeared to have occurred while the boat repeatedly beat against the rocks with wave action.
  The primary contributing factor is weather. After Vessel 1 sustained motor failure/malfunction the northern winds pushed the vessel southward and grounded it on the concrete wave barrier/rocks. If the winds were non existent, the vessel would simply have lost power and the operator would have been waiting assistance. The secondary contributing factor is operator is operator attention for failing to perceive the dangerous weather and water conditions that had been accurately forecasted for days prior and not ensuring that his vessel was mechanically sound before taking it out. The tertiary contributing factor is operator inexperience due to the operator not realizing the lake would be that rough given the weather and not being aware of the capabilities of this vessel. The subject had claimed to have PFDs aboard the Vessel 1 type 4 PFD was recovered from the shoreline. There was not sufficient evidence to suggest intoxication was a contributing factor in the incident. The type of incident is grounding.
