RedactedNarrative: On April 9, 2017 at approximately 15:00 Operator was operating an airboat in the vicinity of Sullivan Lake.  Upon making a sharp turn to starboard, in order to exit the lake into a bayou, the vessel began to slide to the port side.  A strong wind from the east (starboard side) made the turn more difficult.  Operator then picked a clear spot on the bank to run the vessel aground.  Upon hitting the bank the vessel did not continue on course but made a sharp turn to the starboard causing the vessel to strike a tree on the starboard side of the bow.  No injuries were sustained by Operator or his passenger.  Moderate damage was caused to the vessel hull and engine.  PFD's were on board and being used, no alcohol or drug use is suspected and Operator had only about 3 months of operator time on the airboat.
