RedactedNarrative: Both Watercraft #1 and Watercraft #2 were moored to mooring posts on the beach at Lake Carlos State Park. Watercraft #1 was moored with one rope tied to the rear starboard side of the boat. There was enough slack in the mooring rope to allow Watercraft #1 to float away and come into contact with Watercraft #2, which was still moored and in place on the beach. The outboard motor of Watercraft #1 came in contact with the port side of Watercraft #2 and caused damage to the boat.
