RedactedNarrative: On 2/17/19 at approximately 1:30pm Operator launched his vessel from the Archie Glover Boat Ramp in Mulat Bayou. Operator noticed the vessel listing to the starboard side. He boarded the vessel from the dock and turned on his bilge pump. The vessel continued listing more to the starboard side until water began coming over the gunwale. Operator abandoned his vessel and it sank at the end of the boat ramp.
  
  I asked Operator if he normally removed his drain plugs after using his vessel. He stated that he always left the drain plugs in vessel, and that he relied on the bilge pump to drain out any rain water. I believe that the vessel had a substantial amount of rain water inside the hull beneath the deck when Operator launched it. With the vessel listing to the starboard side as it came off the boat trailer, I believe water began spilling from the port side sponson into the starboard side of the vessel. This transfer of internal water caused the starboard side to become heavier until the starboard side gunwale was below the waterline. At which point the interior of the vessel above the deck filled with water and the vessel sank.
