Operator1 and V1 occupant turned around to see operator2's boat strike the starboard stern of their boat, and ramp up over operator1, striking him in the head.  Operator2's boat landed on the operator1's steering console windshield, and then glanced to the starboard side entering back into the water.

  Operator2's boat received several scuffs and gouges on the bottom of the port side hull.
  Both operators stated that the water conditions were very rough in that area due to the other boats participating in the bass tournament.
