Vessel #1 was cruising down stream at a slow rate of speed of 10 MPH or less, because the night was cool and the ladies on board were getting cold.  According to the passengers on board, the running lights and the all-around-light was in working order. They said they turned their lights on at the River Bend Festival when instructed to do so by an unidentified TWRA Officer.  Vessel #2 struck the rear of Vessel #1 at a high rate of speed, launching itself over the top of Vessel #1, and then landing in front of it.  Two of the people on board Vessel #1 sustained head injuries.  According to passenger in Vessel #2, the younger female on board his vessel was ejected from their vessel and had to be helped back aboard.  Operator2's brother-in-law was traveling with them down stream in his vessel, and towed both vessels to the boat ramp at Raccoon Mountain Pump Storage Plant (TVA facility).  There, they were met by TWRA Officers who began the investigation.
