RedactedNarrative: A boating accident occurred on 6-21-14 At approximately in Narragansett Bay. According to passenger statements, there were four occupants on the boat, 2 males and 2 females. The group left Tiverton and headed to East Greenwich Bay. In East Greenwich, the boat was then docked at a restaurant (Harborside) where all four had dinner and alcohol beverages. Although no one could remember if boat operator had any alcohol. After dinner the group got into the boat and headed back to Tiverton with Operator operating the boat. Passenger1 stated that he was sitting on the gunwale looking at the chart plotter when he was suddenly thrown from the boat into the water. He remembered seeing a buoy in front of him when he was in the water, but was unsure what the boat crashed into. Sgt. and EPO set out in a DEM patrol boat to view the navigational aid that Portsmouth Fire Personnel said was struck. The first aid they encountered, they observed a scrape and dent with a black bottom paint transfer on the edge of the main flotation portion of the buoy. There were also scrapes under the waterline. There were pieces of pink fiberglass jammed into a large bolt and other fragments strewn about the whole structure of the buoy with one piece deposited up near the top reflector. Other damage revealed that struts had been bent and torn from the welded area. Pieces had been bent in an upward direction as far up as the highest point on the buoy. Upon inspection of the boat which sustain extensive damage consistent with damage to the buoy, it was obvious to officers that Operator’s boat crashed into #2 buoy . DEM officers also observed several beer cans and Smirnoff wine coolers about the deck. According to Sgt. investigation, excessive speed was the cause of the accident.
