RedactedNarrative: Operator had just bought the vessel that morning. Operator took the vessel to Estill Springs City Park to launch it in Tims Ford Lake a little before 2pm. According to witnesses; Operator launched the vessel and left the bank headed towards the channel. A witness stated that he heard the engine rev on the vessel and looked and saw the vessel''s bow rise up and turn to the left. Operator fell out of the vessel on the port side over the transom. Operator started calling for help and trying to stay above the water.  Two people on the bank started swimming towards Operator to try to help him. One of the Witnesses stated that he was able to get to within about 60 ft away from Operator before he went under the water and never came back up.  Good sam1 climbed on board Operators boat, which was idling in a circle, and picked up the other individual that was swimming out to try to help. They kept looking for Operator for 15-20 minutes but were unable to find him. Good sam1 also stated that when he climbed on board Operator''s vessel and started driving it he noticed that the throttle was very sensitive and that it nearly threw him out when he first started driving it.  When I arrived at the scene I found that Operator''s vessel did not have any PFD''s on board and the Witnesses said that there were none floating in the water after Operator fell out. Operator was found a few hours later by rescue squad divers on the bottom of the lake near where the witnesses had said that they last saw him. When Operator was found he was not Wearing a PFD. When I spoke to Operator''s Wife she told me that Operator could swim but that he had had shoulder surgery and that may have made it hard for him to swim.
