RedactedNarrative: The Victim was tubing when he was knocked off the tube and started yelling for help.  The Operator of Vessel 1 (the towing vessel) heard the Victim yelling and realized that the Victim had fallen off the tube.  There was no observer on board the vessel to watch the tubers' progress at the time of the incident. Vessel 1 then experienced engine issues and stalled out.  Several minutes later, the Operator was able to restart the engine on Vessel 1 and turn back toward the Victim.  Upon returning to the area where the Victim was seen, the Operator reported being unable to locate the Victim and discovering only a yellow type II PFD floating in the area.  The Operator stated that the Victim was wearing a PFD at the time of the incident.  The tuber was wearing a type 2 flotation device, but the waist buckle that secures the PFD could not have gone around the Victim (size) which allowed the PFD to slip over his head upon entering the water.  The incident occurred directly in front of the East Fork main beach and many swimmers witnessed the tuber struggle for 30-45 seconds while the operator attempted to restart the stalled engine on Vessel 1. 
  
  Sonar was used to recover the Victim at 2:55 a.m. the following morning.
