RedactedNarrative: Vessel one:
  Rental pwc was returned partially submerged and accident was reported by rental company.  I contacted the operator of the pwc who was on a different vessel.
  
  Operator statement:
  Operator one advised he was somewhere in the north basin near the west shore heading south when he approached an unknown white boat.  He was inexperienced and panicked and turned too late as the two approached head on.  Vessel one turned to port and was struck on the right gunnel causing a large gash.  Vessel two stopped to render aid and was reported to have no damage and went on their way as there was no damage.  He advised he was struck by the front starboard bow of vessel two.
  
  Investigation:
  The operator of vessel one advised he was in a large party who had rented a pontoon boat and another pwc.  The owner of the rental company suspected the other pwc was the actual other vessel involved in the collision but there was no evidence to support that claim.  V-1 operator could not provide a specific location and a good description of the other vessel involved
