RedactedNarrative: Operator was driving his boat in Mule Creek Bay towing a surfer when storm clouds
  became visible in the distance. They drove to the middle of Coulter Bay and Pat’s Point. They then
  brought everyone into the boat, drained the ballast tanks, and took Justine and one other girl to the
  dam and dropped them off. He then planned to drop occupants at the Coulter Bay boat ramp. About 80 feet from shore (near Bear Claw), he bottomed-out
  his boat on a rock/sand bar. He slightly hit the throttle because he was knocked into the throttle
  lever. The boat bounced back and to the side about 2-3 feet (loud thud, sounded like the driveshaft
  broke). He immediately went to neutral and shut the boat off. Operator then stood on the bow to flag
  another boat for help, but he was unsuccessful. Individual called his father in law who had another boat
  on the water (tri-toon boat) at Keyhole. While Operator was waiting for individual, the boat drifted to the
  north side of the Coulter Bay boat ramp. Operator tied a rope to the bow of his boat and had him pull
  them to the Pat’s Point boat ramp. Operator loaded the boat by hand and trailered the boat to
  Homestead Campsite.
