RedactedNarrative: V1 was operating the PWC and encountered some large wake made by another boat.  When they hit the large wake, it caused the passenger to fall forward to the port side of the PWC.  The operator attempted to keep the passenger on the PWC by accelerating toward the port side, yet it was too late.  The passenger fell forward & struck his head on the PWC before falling into the water face down & unconscious.  The operator jumped into the water & righted the passenger.  It took about 20-30 minutes before the passenger came to & was then loaded onto a boat & taken to shore.  Both subjects were wearing life jackets.
