RedactedNarrative: Unit 2 was anchored in about 5' of water on the north side of the river waiting on the tide to go out.  The occupants could hear Unit 1 approaching and saw them moving in their direction.  An occupant on Unit 2 flashed a spotlight at unit 1 when they were roughly 30 yards away.  Unit 2 heard the occupants of Unit 1 scream and at the last minute, the operator of Unit 1 turned towards the stern of Unit 2, colliding with the vessel.  The collision broke Unit 2's steering system.
