RedactedNarrative: The operator had driven past the docks of his property in a north westerly direction as the tube with the passengers proceed south of the boat and was sling-shooting closer towards shore. As the tube became closer to a yellow floating platform/dock, it became apparent to one of the riders that they were going to collide with the dock and she let go of the tube falling into the water prior to impact. The victim remained on the tube struck the yellow floating platform. She was thrown from the tube and skidded across the top of the platform before coming to rest in the water. 
  
  
  The operator indicated that he had driven passed the property in a northwest direction and had circled around to go by the camp and failed to judge the distance accordingly. He said as the tube drifted toward shore it caught the yellow dock. The operator said he believed a contributing factor was that that day he had lengthened the tow line behind that boat by attaching a length of yellow tow strap to the orange tow line to give more distance behind the boat, so the tubers would not catch the spray from the jet drive, which has been a problem in the part.
