RedactedNarrative: THIS CRASH OCCURRED AS OPERATOR 1 WAS ATTEMPTING TO TAKE PICTURES OF PEOPLE JUMPING OFF THE CLIFF. ACCORDING TO OPERATOR 1, VESSEL 1 WAS IDLING IN REVERSE OR DRIFTING BACKWARDS AND SOMEONE YELLED AT OPERATOR 1 THAT HE WAS GETTING TOO CLOSE TO THEM. WHILE REACHING FOR THE THROTTLE, OPERATOR 1 APPARENTLY FELL, CAUSING THE THROTTLE TO GO FULL THROTTLE IN FORWARD. AT THAT TIME, VESSEL 1 STRUCK SWIMMER 2 AND SWIMMER 3 AND THEN IMPACTED THE ROCK BLUFF.
