RedactedNarrative: On July 15, 2016 at approximately 22:00 hrs, Operator1 and Operator2 were both operating their vessels on the Meigs County section of Watts Bar Lake. Operator1''s vessel had 6 other passengers (Listed in this report) and Operator2''s vessel had 1 other passenger (Listed in the report). 
  
  Operator1, the operator of Vessel 1, a 26'' JC Tritoon (TN0256DJ), and Operator2, the operator of Vessel 2, a 22'' Sylvian Pontoon (TN7232EC) were traveling down river. Vessel1 was in front of Operator2''s vessel. At approximately 22:00 hrs Operator1 had slowed his vessel and was attempting to navigate his vessel and dock it in his personal boathouse. At that time Operator2''s vessel was traveling toward Operator1''s vessel. Operator2 stated that there were bright white lights on the shore at a neighbors house and that he did not see Operator1''s vessel until he collided with it. 
  
  The left side of the bow of Operator2''s vessel made contact with the stern and inboard/outboard of Operator1''s vessel causing damage. Alcohol was not a contributing factor. The primary contributing factor to the accident was the bright lights on the shore. The lights blinded Operator2 and he was unable to see that he was approaching Operator1''s vessel. My investigation is complete.
