RedactedNarrative: On July 14, 2018 at approximately 3:00 pm (est.) two people were both operating their vessels. on Watts Bar Lake around the area named "the fingers." Both Vessels were going into the cove when Operator2 turned his vessel to the right. Operator2 then realized that there was another vessel behind him. He attempted to make a maneuver with his vessel but was unable to avoid the collision with vessel1. Operator2''s vessel struck V1 on the port side toward the bow and back mid vessel. The damage to Operator2 vessel was on its port side as well. No alcohol was involved. My investigation incomplete.
