Operator was pulling two people on a tube behind a PWC.  Operator was operating the PWC in a narrow part of Lake McQueeney.  Operator made a sharp u-turn and the tube slung out wide and hit a boat dock.  Tuber1 took the brunt of the impact, suffering a broken left femur.  Tuber2 had some small cuts and was not transported to the hospital.  Tuber1 was airlifted to University Hospital in San Antonio, Texas.  The rope that was being used to tow the tube was a water ski rope.  It was too long to be used for pulling a tube, the PWC operator could not control the tube behind the PWC.
