RedactedNarrative: VESSEL 1 WAS DRIVING SOUTHBOUND ON THE MISSOURI RIVER WHEN THEY PASSED ANORTHBOUND JET SKI WITH TWO PEOPLE ON IT.  A SHORT WHILE LATER VESSEL 1 HEARD SOME SCREAMING AND YELLING COMING FROM BEHIND THEM FROM THE JET SKI THEY JUST PASSED. THEY SLOWED UP TO SEE IF THE JET SKI WAS SOMEONE THEY KNEW.  THE JET SKI APPEARED TO BE UNDER POWER AND STRUCK THE STARBOARD SIDE OF VESSEL 1 GOING UP OVER THE GUNWHALE AND BACK DOWN.  
  
  VESSEL 2'S VERSION WAS THEY WERE IDLING AND ANOTHER BOAT PASSED THEM THROWING A WAKE AND WAS PUSHING THEM INTO VESSEL 1.  THE OPERATOR OF VESSEL TWO TRIED TO AVOID THE COLLISION BY APPLYING POWER BUT COULD NOT AVOID IT.
