RedactedNarrative: Watercraft #1 was coming into the public access to load onto the trailer. Watercraft #2 had just unloaded from the trailer and was backing onto the lake. WC #1 collided with WC #2 causing very minor damage to WC #1 and some damage to WC #2. Operator #1 admitted he wasn't watching and didn't see WC #2. Life jackets were not being worn in either boat. There were no injuries. Alcohol was not a factor.
