RedactedNarrative: On September 10th, 2021 at approximately 11:41 hrs. EST  I, Officer, responded to a boat accident on Fishing Creek near Needle Point, involving a 2021  Mystic Powerboat 42' in length. Upon arrival at Lee's Ford Marina I met the Somerset/Pulaski County EMS as they were attending to the injured. They advised me that Air Evac was in route. I assisted the Air Evac medical team to the marina to assist the Somerset/Pulaski County EMS. After all subjects were transported from the marina I followed up with them at the Lake Cumberland Regional Hospital. Two subjects were flown to Lexington UK Medical Center, one with a possible pelvic bone break, lower lumbar injury, internal bleeding  and injured ribs with his run being XX. The other subject had a severe cut to his lower right leg/foot area with his run being XX.  At the Lake Cumberland Regional Hospital I spoke with the operator of the vessel. He stated that they were traveling toward Needle Point and hit a wave nearly capsizing the boat, ejecting all occupants but one. Subject was uninjured and remained on the vessel and was able to get the vessel back under control. Due to the engine lanyard not being used by operator the vessel was still underway after ejecting the passengers. The owner/operator was later sent to Lexington to the UK Medical Center due to his injuries. The total number of subjects on the vessel were eleven with ten of them having injuries beyond first/aid. There was no noticeable damage to the vessel and no sign of blood on the vessel from any injuries. Photos were taken at the marina before the vessel was returned back to State Dock. Paper work from the vessel was obtained verifying that it was a new boat that had not been registered as of 09/10/2021 and also showed having verification of being insured. Statements were taken from the owner/operator at the Lake Cumberland Regional Hospital. I observed the vessel having a engine lanyard attached to the kill switch in the on position but was not being used and was wrapped around the control area on the dash of the vessel. The vessel did contain the required number of PFD's and other required safety equipment.
