RedactedNarrative: According to both operators, they were operating their PWC''s upstream from the Savannah bridge (hwy64) in the Wolf Island area on Kentucky lake. The operators were returning to a private boat ramp off of Catfish Lane in Crump,TN. The operator of V2 stated she was headed upstream with her son (V2 passenger) sitting in front of her when she let off of the throttle of the PWC she was riding. Operator2 states they began to float at this time near the campers upstream from the bridge. She states that Operator1 (V1) was already ahead of them. She then states that while they were floating, they had turned and faced back towards the bridge. It is at this time she states her and her son were struck on the left (port) side causing injury to their left legs. Operator2 states that she and her son were stopped and she noticed Operator1 first to her right and then when she looked to her left, he hit them. The operator of V1 stated that Operator2 and him were floating together and had stopped for a moment. He then states they were facing opposite directions and both began to travel again at the same time. Operator1 says he throttled up and made a circle to pass behind Operator2''s PWC. He continues by saying that it appeared they let off the throttle in front of him and he then hit them on the side. Both operators state the impact threw both V2 passenger and Operator2 from their PWC.
