RedactedNarrative: WC #1, a personal watercraft, was pulling a tube with one person on the tube. The tow rope got sucked into the impeller of the PWC, causing the PWC to stop. They started to drift towards the public docks. When they got close enough to the docks, the tuber was able to get off and try to remove the rope from the impeller. He was pulling on the rope and told the operator to turn on the PWC in order to allow the rope to clear itself. When the PWC was turned on, it appeared that the rope was sucked further in causing it to tighten and then snap, with the tuber's finger stuck in it. The tuber was assisted to the dock to wait for help. He was transported to the hospital by ambulance. Life jackets were being worn and alcohol was not a factor. There was no damage to the PWC.
