RedactedNarrative: Individuals on scene stated that waves started coming over the bow on Vessel 1 that was towing Vessel 2, and that it was traveling approximately 10 mph, and waves were 4-6 ft. high.  Vessel2 was not operational due to engine issues. They confirmed that everyone else was safe on the shore directly across from where we were.
  
  Additional follow-up was conducted and information gathered. Based on my investigation, pictures, interviews, and witness statements - the main contributing factors in this incident were operator impairment, operator inattention and operator inexperience (towing in heavy weather).
