RedactedNarrative: VESSEL 1 WAS ATTEMPTING TO DOCK AT THE BOAT LIFT DIRECTLY TO THE LEFT (NORTHWEST) OF VESSEL 2. WHILE ATTEMPTING TO DOCK, THE PORT SIDE FRONT CORNER OF VESSEL 1 CONTACTED THE REAR FACE OF THE PORT SIDE PONTOON OF VESSEL 2, CAUSING THE DAMAGE TO VESSEL 2 AND TRANSFER MARK TO VESSEL 1. VESSEL 2 WAS EMPTY WITH NOT OCCUPANTS AND WAS OUT OF THE WATER ON THE LIFT WHEN IT WAS STRUCK. THE OPERATOR OF VESSEL 1 STATED THAT THEY TRIMMED THE MOTOR UP AND TURNED THE VESSEL OFF WHILE DOCKING, WHICH MOST LIKELY CAUSED THE REAR END OF VESSEL 1 TO SWING AROUND.
