Vessel #1 was operating and for some reason slowed.  Vessel #2 approaching from the stern of vessel #1 failed to have a proper lookout and then panicked letting off the throttle thus inducing a loss of steering in the PWC.  Vessel #2 continued on its course and struck vessel #1 and ran up and over it.  When this occurred operator #1 was struck and ejected of the vessel.  The operator of PWC #1 was knocked unconscious and suffered a broken jaw, concussion and a bloody lip.  The operator of PWC #2 suffered no injuries.
