RedactedNarrative: Watercraft #1 was trolling eastbound approximately 300 yards out from shore north of Gull Point, when the occupants noticed Watercraft #2 approaching from the stern. Occupants of Watercraft #1 attempted to yell and wave at Watercraft #2 to gain its attention but were unsuccessful. Watercraft #2 struck the starboard rear corner of Watercraft #1, and then went up over the top of Watercraft #1. The operator of Watercraft #1 jumped overboard and appeared uninjured at the time of the accident. One of the passengers from WC #1 was injured by WC #2 and was taken to the hospital by ambulance. The third party from WC #1 was uninjured. After the accident, WC #2 turned around and attempted to render aid to WC #1. One of the parties from WC #2 jumped in the water and swam over to WC #1 to assist. Both watercraft made it safely to shore and tied up to the docks at Ernie's Restaurant. Of the eight parties on WC #2, 1 person was injured and was transported to the hospital for treatment. The operator of WC 2 was arrested for BWI. Operator #1 said he had a couple of beers earlier in the day, but had no indications present for drinking.
