RedactedNarrative: Operator report only:
  While preparing to take 3 riders tubing, rider 1 jumped off the rear platform of the boat onto the tube.   His feet landed on the tube first, which cause the tube to push away from the boat.  This caused him to fall forward and hit his jaw/face on the rear of the swim platform.  He was instantly knocked out and fell into the water. Other riders jumped in to pull him back into the boat.  We immediately returned to the dock, where our group of friends and EMTs were waiting to render aid.
