RedactedNarrative: Operator was traveling south on Bayou Amy when his vessel (LA5993ES) struck an object in the water. Upon hitting the object Operator looked behind his vessel to see what he had hit and at this time he struck a second object which caused his vessel to come up out of the water. The impact threw the motor up which caused the cover of the motor to come off, fly forward and strike Operator in the head. Operator had an approximate 3 inch laceration on his head from the motor cover striking him. Operator, his wife and son idled to the east bank and waited for an ambulance to pick them up. The other subjects had no injuries to report of. Operator's 3 inch laceration on his head required 6 staples to close. Operator had admitted to drinking and refused to give blood or urine while at the hospital. He submitted to HGN but refused any other SFST's. Sr. Agent brought him to Breaux Bridge PD where he refused to blow in the Intoxilyzer 5000. We then booked him into the St. Martin Parish jail. The only evidence of PFD's used was a child's PFD on the deck of Operator's vessel.
