Witnesses stated that a group of PWC riders were driving eratically and thought someone was going to be killed as they were jumping over one another, wake jumping and driving at excessive speed.  Investigators found statements from riders not consistent with evidence found on the pwc.  Investigators felt that the pwc had been in a collision turning this accident but witnesses did not see a collision or actually what happened during the accident.  According to operator a wake from a passing vessel struck the side of the PWC causing him and his passenger to roll to the right.  There was extensive damage on the pwc that the operator claimed happened in the past but the investigator felt that the property damage to the starboard area (where his foot was) was heavily damaged and would have taken on water if operated.
