RedactedNarrative: THE PRIMARY CAUSE FOR THIS CRASH WAS OPERATOR 2'S FAULT.  OPERATOR 2 DID NOT KEEP A PROPER LOOKOUT OR TAKE EVASIVE ACTION TO AVOID THE COLLISION.  OPERATOR 2 WAS ALSO OPERATING TOO CLOSE TO ANOTHER VESSEL AND AT AN EXCESSIVE SPEED AS SUCH, IF OPERATOR 2 WAS TRAVELING SLOWER HE MAY HAVE SEEN VESSEL 1'S NAVIGATION LIGHTS IN TIME TO TAKE EVASIVE ACTION.
