RedactedNarrative: The vessel was heading back to shore at less then cruising speed and the operator thought he heard a thud on the right side of the vessel. The operator thought they left the bumpers on and when they looked over the side they saw it was a swimmer that they had seen earlier in the lake. The swimmer had been swimming/playing around in the lake and they had seen her in the distance. It had been about an hour when they were heading back to shore and they didn't see here anymore. 
  
  The swimmer was under water at the time she made contact with the bottom of the vessel. The operator didn't realize that she was even there and hit here. They pulled her aboard, had called 911 and she was taken to the hospital and received 6 stitches. 
  
  The swimmer stated that she heard the boat motor underwater and when she tried to surface is when she made contact with the vessel. It was reported that there was no negligence on either party and no alcohol involved.
