RedactedNarrative: On 10/29/2015 between 1900 hours and 2230 hours a vessel capsized at the Beach Marina located at 2315 Beach Boulevard, Jacksonville, Florida.
  
  The boat had previously been stored on a trailer before (the owner) had taken it out on the water with (the operator).  Boats stored on trailers, if they are stored properly, have the drain plug removed so that rainfall will not accumulate in the boat.
  
  Once the boat was launched and Occupant and Operator were on the water the bilge pump would of pumped any water out of the boat that came in through the open drain plug hole.  This coupled with the forward motion of the boat kept water from noticeably coming onto the interior of the boat.  It is then reasonable to believe that neither Occupant or Operator would of realized that there was no boat plug installed during their trip.
  
  Once Occupant had tied his boat up to rented space at approximately 1900 hours on 10/29/2015, with the bilge pump turned off, then the  water gradually seeping into the boat from the open drain plug caused the boat to list and eventually capsize.
  
  Once I had arrived at the scene on 10/30/2015 I made contact with salvage operator contracted by Occupant, he verified that there was no drain plug installed in the boat.
  
  My investigation revealed that Occupant and Operator had failed to install the boat's drain plug causing the boat to fill up with water, list, and then capsize at the slip rented by Occupant.
  
  I issued no citations.  I observed no physical damage to the vessel although there could be damage from salt water infiltration into various mechanical and electronic parts of the vessel during the capsize.  I further observed no environmental damage caused by fluids leaking from the vessel.
  
  Case status:  Closed.
