RedactedNarrative: V1 WAS TRAVELING SOUTH THROUGH THE NARROWS OF SHOAL BAY WHEN IT ENCOUNTERED ANOTHER VESSEL TRAVELING NORTH. V1 MANEUVERED TO THE RIGHT TO ALLOW THE VESSEL PLENTY OF ROOM TO PASS WHEN A THIRD VESSEL ALSO TRAVELING NORTH ATTEMPTED TO PASS THE SECOND VESSEL THAT WAS ALREADY MEETING V1. V1 PERFORMED AN EVASIVE MANUEVER TO THE RIGHT AGAIN AND STRUCK AN OVERHANGING TREE ON THE STARBOARD SIDE.  V1'S STERN THEN CONTACTED SEVERAL LARGE ROCKS IN THE SHALLOW WATER.  NEITHER OF THE NORTH BOUND VESSELS STOPPED OR WERE IDENTIFIED.
