RedactedNarrative: On November 27, 2016 at approximately 1315 hrs. subjects were both operating their vessels on Chickamauga Lake in Hamilton County (GPS coordinates of approximate accident location provided in report). Operator1 was operating his 18''6" Triton bass boat (GA 6434 EL) outside of Wolftever access area. He was at idle speed and approaching the Hwy. 58 bridge crossing over Chickamauga lake. As he approached he observed Operator2 operating his vessel, a 18'' Venture bass boat (GA 0402 BG), in a way to where the vessel was plowing with the bow raised high in the air. Operator2 was coming under the Hwy. 58 bridge. Operator2 stated that he could not see Operator1''s vessel because he was plowing and his vision was obstructed by the elevation of his bow.
  
  Prior to impact Operator1 steered his vessel to the right to attempt to avoid contact. Operator2 did not attempt to maneuver his to avoid the collision because he did not have the proper lookout and could not see over the elevated bow of the vessel. The port side of Operator2 vessel struck Operator1''s vessel on the port side and continued to inflict damage to the port side and to the outboard engine. After impact both vessel came to a quick stop and then Operator2 continued his track to the access area with Operator1 following. 
  
  In conclusion, Operator2 contributed to this accident by not keeping a proper lookout and by elevating his vessel in such a way to restrict his viewing. Operator1 did not contribute to the accident.
  
  Operator2 stated that the reason he was operating his vessel at such a speed and manner was due to his boat filling with water. We were not able to determine the cause of the water filling his vessel. Further analysis by a professional mechanic or technician to determine that would be required, but is not pertinent to this investigation. 
  
  All evidence collected and analyzed to come to my conclusion was obtained on 11-27-2016 at Wolftever access area. My investigation is complete. Operator2 was given a warning for not having a type IV PFD on his vessel.
