RedactedNarrative: On 10/01/16 at approximately 1530 hours (operator 1) and (passenger 1) were traveling North North East from Lake Hatchineha to the Dead River. Operator was operating an airboat bearing FL9647EA (vessel 1). They were crossing the marsh known as Candler's Marsh. The air boat struck a barb wire fence, which crossed the bow of the vessel, and brought the vessel to a stop. 
  
  Occupant's left leg impacted the fence causing deep lacerations to the leg. Fence post were knocked down from the vessel impacting them and the wire cut to remove Occupant's leg. The fence was obstructed by tall over grown grass line. Operator took the vessel and Occupant back to the ramp he launched from, where EMS and law enforcement responded. 
  
  I observed a dent and scratches to the port side of the airboats grass rack, scratches to the metal works below the front single passenger seat. The scratches were also on the port side metal works frame. I read operator miranda from a Polk County Sheriffs Office miranda card and he agreed to telling me what occurred. 
  
  Operator advised that he was traveling from Lake Hatchineha to the Dead River in what is called Candlers Marsh. He advised that he was on an airboat trail for approximately one and half miles, then on dry ground for approximately 200 yards, he entered a high grass area approximately 600 yards from the Dead River. He advised that he did not see the barb wire fence and struck it with the vessel. 
  
  He advised that Three strands of wire went under the hull of the boat. Two strands crossed over the bow of the boat striking Occupant and the boat. The impact of the vessel with the fence stopped the vessel. He estimated his speed less then 10 M.P.H. at the time of impact and that he was only 10 to 20 yards from the fence when he seen it in the high grass. He advised that he wrapped Occupants leg up, cut the wire, and transported him back to Camp Mack. He advised that there was a total of five airboats running the marsh with him. He could only give me the contact of one (witness). He advised that he was operating the vessel and Occupant was in the front passenger seat. 
  
  Operator could not give an exact location of the incident. I attempted to make contact with Occupant and was informed that he was undergoing surgery to the injured leg. I made contact with witness and he advised that he did not witness the actual impact of the vessel with the fence. He advised that He left the water of Lake Hatchineha and entered the marsh traveling north north east, traveling too Lake Cypress. He advised that he thought Operator was stuck and when he approached seen the vessel was entangled in the fence. He advised two strands were across the bow of the vessel and in Occupant's leg. He advised that he assisted with freeing the vessel. He also could not give an exact location of the incident. He advised that he was in the marsh from Lake Hatchineha approximately 5 minutes. He advised that there was high grass, however there w…
