RedactedNarrative: On 09/15/22 at approximately 1605  I, Game Warden 1, was going to the Brunswick Office when I noticed a vessel sitting on top of the Liberty Ship Park boat ramp dock. Beside the boat was an individual in the water clinging to the dock while another person was trying to pull them from the water. I immediately drove to the boat ramp. I  climbed over the vessel and pulled the kill switch. I then proceeded to assist Good Samaritan in pulling Operator from the water. Operator told me that while attempting to dock the vessel the out going current caused the boat to strike the dock and knocked him over onto the throttle. The sudden increase in throttle ejected him from the vessel and pushed the vessel on to the dock. Operator was not injured during the accident. The vessel sustained substantial damage to the hull. The bow and stern of the vessel's hull had punctures from the cleats on the dock. The starboard side of the hull has a large scrape into the clear coat below the water line. The port side of the hull has a large scrape in the clear coat right below the registration number. The chine on the port side was scratched through the gel coat. Sea tow responded and pulled the vessel off of the dock and helped to trailer it.
