RedactedNarrative: OPERATOR 1 WAS OPERATING VESSEL 1 WHILE TOWING A WATER SKIER WHO WAS FLY BOARDING. AS THE WATER SKIER OPERATED THE FLY BOARD APPROXIMATELY 10 TO 12 FEET UP IN THE AIR ABOVE VESSEL 1, THE WATER SKIER LOST THEIR BALANCE AND VEERED TOWARDS VESSEL 1. THIS CAUSED THE WATER SKIER (FLY BOARDER) TO IMPACT VESSEL 1 AND SUSTAINED INJURIES. VESSEL 1 SUSTAINED DAMAGE FROM THE IMPACT WITH WATER SKIER (FLY BOARDER). THERE WAS NO DAMAGE TO THE FLY BOARD THAT THE WATER SKIER WAS USING. THE OPERATOR OF VESSEL 1 DID NOT SUSTAIN ANY DAMAGE FROM THE IMPACT.
