RedactedNarrative: V1 AND V2 WERE BOTH ON PLANE, V2 WAS TRAVELING UP RIVER AND V1 WAS TRAVELING DOWN RIVER. BOTH VESSELS WERE NAVIGATING THROUGH TURNS. THEY BOTH ENTERED A NARROW CHUTE AT THE SAME TIME FROM DIFFERENT DIRECTIONS. V2'S PORT SIDE BOW STRUCK V1'S PORT SIDE CENTER AND V2 WENT OVER V1 STRIKING V1'S MOTOR. THIS PROCESS CAUSED THE DAMAGE TO BOTH VESSELS.
