RedactedNarrative: On may 22, 2014 at approximately 1600 hours i received notification from glen canyon dispatch that a boater was injured while operating on lake powell and he was being boated into antelope launch ramp.  Patient was transported to page hospital er.  I contacted the operator at the hospital.  She reported that the injured party was holding onto the tubing rope to avoid getting it caught in the propeller.  The vessel they were on was not moving at the time, but had a tube in tow with one person on the tube.  When the operator put the boat in gear, the rope got caught in the propeller while the injured party was still holding the rope.  This caused the injured party to be pulled into the water.  The injured party hit his head on the back deck of the boat.  Friends helped the injured party out of the water and onto another boat that was passing by.  This vessel transported the injured party and others to antelope point launch ramp where they were met by awaiting ems.
