RedactedNarrative: The vessel was heading north bound on the Colorado River after leaving Fox's River Bar shortly after midnight. The weather was severe with low visability due to high wind.  The operator unable to see clearly collided the vessel with the shoreline on the Arizona side across from Echo Lodge.  The operator of the vessel was struck with a large tree branch which appeared to break his neck.  Four of the five additional passengers were injured, but only minor injuries.  We are not aware at this time if alcohol played a part in this collision.  There are blood results pending.
  
  The autopsy toxicology report concluded alcohol was involved as the victim/operator was impaired by operating a vessel with a BAC in excess of 0.08 BAC.
