RedactedNarrative: Summary
  On February 18th 2017 I received a call from Glen Canyon Dispatch about a vessel that sustained damage overnight at Antelope Point Marina. I arrived at Antelope Point Marina where I was directed to the maintenance shop where the vessel was located. I went to survey the damage to the vessel.
  
  Initial Call
  I received a call about a single vessel accident that occurred in the Antelope Point Marina dock. There was limited information given to me about the accident.
  
  Investigation
  I went to Antelope Point Marina where I met with one of the employees with cart services. She drove me to the Dry storage maintenance area where I observed vessel on a trailer in the warehouse. There was an Antelope Point Mechanic working on the vessel. I was able to interview the mechanic as to what caused the vessel to take on water and partially sink. The mechanic stated something to the effect when he pulled the vessel from the water the bilge plug was still in the boat, water was inside the engine compartment and the electric bilge motor was not operating. The mechanic did not have an answer of why the vessel took on water and partially sank.
  
  According to the mechanic this vessel was used by the owner one week prior, February 10th, to it sinking and no one was observed on the vessel since then.
  
  Damage
  The damage to the vessel consisted of damage to the interior, engine, electronics, and exterior of the vessel. The interior was saturated with water and there was an oil ring on the seat cushions, windows, carpet and helm from where oil seeped into the water due to the engine being flooded with water. The engine was being worked on by a mechanic and was having the water and remaining engine fluids drained and serviced. The mechanic did not think the engine was damaged as it was not running at the time of the swamping. The damage consisted of damage to the helm electronics and gauges.
  
  There was no visible damage to the hull exterior of this vessel.
  
  Conclusion
  Based on the interview of the mechanic it is unknown why the vessel took on water and partially sank. There was no exterior damage to the hull or outdrive and according to the mechanic the bilge plug was in the vessel. The electronic bilge pump failed or was overwhelmed by the amount of water that entered the vessel.
  
  The vessel was repaired and service by Antelope Point Marina.
  
  Investigation totaled 5 hours to complete.
  
  End of report.
