RedactedNarrative: THIS CRASH OCCURRED PRIMARILY DUE TO OPERATOR 1 FAILING TO MAINTAIN A PROPER LOOKOUT, AND BEING INATTENTIVE TO OTHER BOATERS. INITIALLY, OPERATOR 2 HAD CHANGED COURSE TO AVOID VESSEL 1, BUT HAD BECOME INATTENTIVE TO THEIR WHEREABOUTS UNTIL IT WAS TOO LATE. OPERATOR 1 FAILED TO EXERCISE THE HIGHEST DEGREE OF CARE WHILE OPERATING A VESSEL.
