RedactedNarrative: According to a statement given by the operator, Operator was returning downstream from the area of Twin Cove Marina to the Tennessee Valley Authority (TVA) boat ramp located off of Oak Grove Rd. While traveling towards the ramp, he was using a spotlight to look for debris in the water. As Operator got in the area of Mtn. Lake Marina, he noticed a boat coming up stream in the opposite direction. Operator stated that the boat traveling in the opposite direction was traveling towards his path and Operator turned off the spotlight he was using. After Operator''s spotlight was turned off the two boats passed. Once the boats had passed, Operator turned his spotlight back on and noticed a large white floating sign in his path. He stated that the sign did not have any lights or reflectors on it. When Operator noticed the sign, he did not have time to maneuver his boat to keep from colliding with the sign. After the collision, Operator continued to the TVA ramp where he pulled his boat out of the water and returned home. His boat suffered damage to the starboard (right) side.
