RedactedNarrative: Vessel one, a 1992 19 foot commander, was beached at the sand bar with three adults and two juveniles on onbard.  The owner of the vessel who was onboard the vessel, advised that he pushed the boat off of the sandbar. He said that he did not try to start the vessel until he was in open water due to it being a jet boat.  He further advised that once he was in open water, he tried to start the boat, but it failed to start.  Owner said that he believed the batteries were dead due to them leaving the stereo on.  Owner advised that several large boat wakes then over took the boat, causing it to swamp.  He further advised that the boat began to sink.  The subjects were all picked up out of the water by good samaritans.  All of the subjects on the boat advised that they were not injured.  The boat was recovered by a salvage company.
  
  The water in the area was very choppy due to heavy boat traffic.
