While on boat patrol at Grayson Lake, I was returning to the marina when I was waved down by individuals that had run their rental pontoon into the embankment. The vessel was approximately half way on the embankment. Upon initial contact I boarded vessel 1 and asked if any medical assistance was needed, both parties denied summoning EMS. After receiving consent from both parties to search the boat and any personal belongings, there was no alcoholic beverages or drugs/drug paraphernalia. I asked who was operating the vessel, Operator stated that he was the operator at the time of the accident. Operator also stated that he had blacked out, and that is what caused him to drive into the embankment. While conversing with the subjects there were no indicators of impairment.

After vessel 1 was towed back to the marina by Grayson Lake Marina employees, I interviewed both subjects. The operator stated that he had blacked out in the past but that it had been two years since his last episode. I then spoke with the Grayson Lake Marina employees to get an estimate of the damages. They claimed that the lower unit outdrive was new, but that it had been severely damaged and would need replacing. There were also several small dings on the hull, and a hole through the perimeter skirting.
