RedactedNarrative: The operator of vessel I was heading in a westerly direction and towing a wake boarder at approximately 17 MPH.  When the vessel turned, the wind caught a wakeboard that had been improperly secured to the rack onboard, blowing it off the boat and causing it to strike the wake boarder in the head. The victim re-boarded the boat and was taken to the operator's residence, where they were met by EMS. The victim was transported to the hospital where he received five stitches for the laceration on his head.
