RedactedNarrative: Vessel 1 and Vessel 3 were drifting, rafted together, when Vessel 2 approached from upriver.  The Operator of Vessel 2 was watching another vessel pass by and when he looked back he saw Vessel 1 in front of him.  At approximately 10 feet away Vessel 1, the Operator of Vessel 2 turned to port; however, the starboard side of Vessel 2 made impact with the starboard side of Vessel 1.  One Occupant aboard Vessel 1, and two Occupants aboard Vessel 2 were ejected into the water as a result of the collision.  Vessel 1 then continued on, pushing into Vessel 3 as well.
