RedactedNarrative: On 09-05-21 at approximately 1943 hours, I responded to a non-injury boat crash involving 2 vessels at the Lake Havasu State Park Launch Ramp. Vessel 1, operated O1, struck vessel 2, operated by O2. Both vessels were operating close together while waiting to take their boats out of the water. Vessel 1''s bow struck vessel 2''s Starboard side causing major fiberglass damage to vessel 2. There is a large gash/hole approximately 12 inches in the fiberglass next to the operator seat. Prior to arrival, both parties exchanged information and vessel 1 left the scene. I spoke wit (V1) on the phone and he stated that he had no damage to his vessel. He said that he was driving towards the launch ramp going approximately 4 miles per hour and V2 cut infront of him causing him to crash into the starboard side. O2 (V2) stated that he was waiting for his grilfriend to back the trailer into the water. He was drifting in the water with his boat off and saw a boat with bright lights coming torwards him. He was then suddenly struck on the starboard side by the bow of V1. O2 stated that he called 911 because he thought that O1 was fleeing the scene. O1 stated he left because they had already exchanged information after the crash and needed nothing further.
