RedactedNarrative: Unit 1 was moored to the dock by the owner at approximately 4:30pm on 07/30/2021.  When employees arrived at work around 10:40am on 07/31/2021, the vessel was discovered to have sunk overnight and was completely submerged.  At the time it is unknown if water entered the hull due to a hull failure or malfunctioning equipment as the vessel has not been recovered at the time of this report.
  
  
  **After speaking with the owner, it was determined that there was a crack in the hull which allowed water to enter the vessel AND the bilge was not functioning properly.  Therefore both hull and equipment are at fault.**
