RedactedNarrative: The operator only remembers going around 60 mph. He then remembers waking up and being put on to the patrol vessel for transport to medical care.  There were no witnesses to the actual accident.  Based on the investigation, operator hit a wake and was knocked out.  Based off his high rate of speed and there being no damage or blood transfer to the PWC, it is most likely that he impacted the water and that is what caused his injuries.  He was observed in the water face down for an unknown amount of time before he was righted and brought back to a nearby houseboat by good samaritans in the area.
