RedactedNarrative: On Sunday July 1, 2018 at approximately 1730 hours Operator 1 was operating an airboat, that was traveling North on the Eastern shoreline of Lake Tiger.  Operator 1 was attempting to turn right when he hit dry land or underwater obstruction.  The sudden stop made one of the passengers (Occupant 1) fall off her seat and strike her head/nose on the mid-section of the port side gunnel.  Operator 1 noticed Occupant 1had a large laceration across her forehead.  Operator 1 told Occupant 1to remain seated and he turned the airboat around and went south along the Eastern shoreline to the nearest house on Lake Tiger.  Operator 1 said he saw a witness standing by the shore feeding her horses and beached the vessel on her property and asked for help.  The witness called 911 and Lake Wales EMS/Fire (14) responded to the witness’s residence. EMS/Fire attempted to life flight Occupant 1 but were unable to due to inclement weather in the area at the time.  Occupant 1 was transported by ground to Lakeland Regional Medical Center in Lakeland, Florida.  Occupant 1 was treated for a 6-inch laceration across her forehead and fractured the bridge of her nose.
