Watercraft was towing a subject on wakeboard.  Watercraft executed a right hand turn to swing wakeboard around to outside of the watercraft''s wake.  As wakeboarding subject swings outside the wake the tip of the wakeboard catches another wake or wave on the lake causing it to go under water quickly throwing wakeboarding subject forward into the water causing him to do what was described to me as several cartwheels on the water before finally stopping.  This motion caused injuries to the subjects neck that required subject to be transferred by ambulance to Bromen Hospital in Bloomington Illinois.
