RedactedNarrative: On 05/22/2016 at approximately 2:30 PM, Vessel 1 was at anchor in "Flat Rock Cove" on Kinkaid Lake.  The owner and his wife were on the watercraft while the their daughter and nephew were swimming.  Approximately 20 minutes after anchoring, they noticed the boat was swamped and appeared to be sinking. 
  
  the boat appeared to be  taking on water from the stern area. The family was able to get the boat to shore and tie it up, however it continued to take on water and became partially submerged.  The motor was completely submerged and is likely a total loss.
  
  Kinkaid Marina removed the watercraft on 05/25/216.  An investigation into the incident by myself, (CPO) on  05/27/2016 revealed the boat did not have any leaks. The boat was filled with water and no water was observed leaking from the hull.  The boat was next launched  into the lake.  Upon doing so, a large amount of water was observed entering the livewell area.    It was also noted the bilge pump did not activate upon being submerged with water and would not function even when the bilge switch was turned to the "on" position.  
  
  It was also noted during the investigation that there had been recent electrical work performed on the livewell areator pump and bilge pump. I tested the power to the livewell pump and bilge pump and noted neither was functioning. Though it was unclear as to what exactly caused the swamping, the boat would not likely have sunk if the bilge pump had been functioning.  The cause of the accident is due to  bilge pump failure.
  
  Owner was given the BAR Form at the completion of the investigation.
