RedactedNarrative: Watercraft #2 approached Watercraft #1 during a water fight. WC #2 was told by a third party to "Go get" WC #1. WC #2 raised their jet motor at a distance of approximately 15-20 feet away from WC #1 and proceeded to spray water onto WC #1. The force of the water broke the middle windshield in WC #1, and sent a passenger falling to the bottom of the boat. He sustained cuts requiring stitches on the left elbow and the right hand. The boats were both approximately 30-40 yards off shore in 8-10 feet of water. They were not anchored when the incident occurred. Life jackets were not being worn in either boat and alcohol was not a factor.
