RedactedNarrative: UNIT 1 WAS TRAVELING NORTH THROUGH THE NAVIGATION BUOYS GOING FROM ISLAND LAKE TO ROUND LAKE AND UNIT 1 WAS TRAVELING AT PLANE. UNIT 2 WAS STOPPED NORTH OF THE BUOYS FACING SOUTH, WAITING TO ENTER THE NAVIGATION BUOYS. UNIT 1 WENT NORTH THROUGH THE BUOYS AND CONTINUED TO BE HEAD ON WITH UNIT 2. UNIT 1 DID NOT CHANGE COURSE AND THE FRONT, JUST TO THE STARBOARD OF THE CENTERLINE, COLLIDED WITH THE FRONT STARBOARD OF UNIT 2. IT SHOULD BE NOTED THIS CRASH OCCURRED AT ABOUT 2230, HOWEVER IT WAS NOT REPORTED TO LAW ENFORCEMENT UNTIL THE NEXT DAY AT ABOUT 0550 HOURS. THE OPERATOR OF UNIT 1 STATED UNIT 2 DID NOT HAVE ANY LIGHTS ON, NAVIGATION OR WHITE LIGHT, SO HE DID NOT SEE THE PONTOON BOAT UNTIL IS WAS TOO LATE TO AVOID THE COLLISION. I SPOKE WITH THE OPERATOR OF UNIT 2, UNIT 2 OPERATOR. UNIT 2 OPERATOR STATED HE OBSERVED TWO BOATS TRAVELING AT PLANE ABOUT TO ENTER THE NAV BUOYS. UNIT 2 OPERATOR STATED HE WAS IN A PONTOON BOAT SO HE DECIDED TO WAIT UNTIL THE OTHER BOATS CLEARED THE NARROW BUOYS. UNIT 2 OPERATOR ADVISED THE FIRST BOAT CLEARED THE NAV BUOYS AND MADE A HARD PORT TURN AND THERE WERE NO ISSUES. UNIT 2 OPERATOR STATED UNIT 1 HUGGED THE RED BUOYS AND AFTER IT EXITED THE BUOYS IT CONTINUED STRAIGHT, TOWARDS UNIT 2 OPERATOR. UNIT 2 OPERATOR STATED HE HEARD THE PASSENGERS START YELLING WHEN THEY WERE ABOUT 30 YARDS AWAY, AT WHICH TIME HE PUT HIS BOAT IN REVERSE IN AN ATTEMPT TO AVOID THE COLLISION. UNIT 2 OPERATOR STATED HE BELIEVED UNIT 1 MIGHT HAVE TURNED SLIGHTLY AT THE LAST SECOND WHICH PREVENTED A HEAD ON COLLISION. UNIT 2 OPERATOR CLAIMS ALL HIS LIGHTS WERE ON AT THE TIME OF COLLISION. UNIT 1 OPERATOR AND HIS PASSENGERS CLAIM NO LIGHTS WERE ON THE PONTOON BOAT.
