RedactedNarrative: At 5:12 AM on Sunday, August 7, 2016, I, Sgt. received a phone call from the Grand Isle Police Department concerning a vessel accident.  Grand Isle Police Department informed me that an notified them about wrecking his boat on the rocks in Caminada Bay.  
  
  After several unsuccessful attempts to contact Owner, I went to the location of the accident. I arrived at the scene of the accident at 5:45 AM and noticed that a vessel, LA9437FD was grounded on one of the several rock jetties in the area.  I immediately took pictures of the scene.  At 6:30 AM, I noticed an individual flagging me down from the dock and the individual was identified as the owner of the vessel.
  
   Owner informed me that the and four other individuals were out fishing under Caminada Bridge and he had a "little too much to drink", so he asked one of the passengers, who hadn't drank anything to drive the boat back to the camp.  
  
  Operator was not familiar with how to operate a vessel nor did she know the area.  Around 3:30AM, as Operator was approaching the rock jetties, she missed the openings through the rocks and the vessel went up and over the rocks.  This caused the aft of the vessel to become grounded on top of the rocks and the bow of the vessel to become submerged.  The accident also caused the lower unit on the motor to be completely ripped off.  The passengers in the vessel called Operator's father-in-law and he retrieved all five individuals from the vessel and brought them back to the camp.  None of the 5 individuals in the vessel were hurt nor were they ejected from the vessel.  
  
  During the investigation, I learned that Operator was not using the GPS on the vessel.  No one was wearing a pfd during the accident, however the vessel was equipped with 6 type I, 1 type 3, and 1 type 4.  Operator violated rule 16 and rule 20 of the rules of the road for vessels.  rule 16 states that all vessels shall be operated at reasonable speeds for given conditions and situations and must be under the complete control of the owner at all times.  Rule 20 states that the owner shall maintain a proper lookout.  Alcohol and/or drugs were not a factor with the driver of the vessel.
