RedactedNarrative: OCCUPANT advised that the two had been hunting squirrels earlier in the day and they had went from Black Creek South to the Mitchell River and then East to the Choctawhatchee River.  After hunting and scouting for duck hunting areas, they began to return to Black Creek Lodge.  While at full speed, approximately 20 mph, the vessel struck a log that they did not see, at this point the boat turned slightly to the left striking a tree on the edge of the river.  OCCUPANT stated that he was seated towards the bow of the boat and was turned in a swivel seat facing the starboard stern direction.  OCCUPANT stated that OP1 was driving the vessel seated near the stern due to the steering being a tiller handle.  OCCUPANT stated that the impact with the tree caused OP1 to hit the deck of the boat busting his ear drum and hurting his head.  OCCUPANT advised that he remained in the same area but ended up laying down no longer seated in the swivel seat. OCCUPANT stated that he did not know the exact location of the accident site but gave me a general area near the mouth of Mitchell River where it meets the Choctawhatchee.  OCCUPANT's Mother arrived on scene and after reading OCCUPANT his rights and with parental consent we questioned him about the beer cans in the vessel and asked if the two had been drinking.  OCCUPANT advised they both had drank one beer earlier in the day.  OCCUPANT did not appear intoxicated and looked to have normal faculties.; OP1: OP1 was transported to Fort Walton Medical due to his ear bleeding after he made impact with the vessel after impacting a fixed object (tree near the bank).   OP1 was diagnosed with a busted ear drum and a concussion.  He made a full recovery from his injuries.
