RedactedNarrative: From operator report
  Trying to load boat onto trailer, it was windy.  I had to back up and turn around to miss the pier.  I accidentally pushed the throttle and the boat spun around and hit the end of the pier with the back bottom of the boat.  It all happened so fast, I have been loading boats onto trailers for years this was not new to me.  It was just a freak accident.
