RedactedNarrative: Operator of vessel #1 was racing 2 other vessels in the mooring field in the "no wake zone" when he struck vessel #2 causing property damage to both vessels.  An off duty policeman who witnessed the accident went over to the scene to see if anyone was hurt.  Operator of vessel #1 fled the scene.  Witness took the registration numbers and called 911.  Operator saw him making a phone call and as a result turned the vessel aiming it at him and his family.  He accelerated towards them shouting obscenities and took off.  The USCG located the vessel with substantial damage to the bow.  Operator was arrested for assault w/dangerous weapon (boat), negligent operation of vessel, and leaving the scene of property damage.  USCG administered a portable breath test; results were over the limits and as a result they will be citing operator for boating under the influence.  MEP cited operator with unregistered operation (expired) and fail to report accident as he did not fill out the boating accident report.
