RedactedNarrative: Occupants were fishing while vessel was anchored fore and aft. Vessel began taking on water caused by waves entering into the back. A vent cap, which was found missing, allowed water to enter into the bilge through a small circular hole which filled the bilge until the vessel eventually capsized. 
  
  The owner swam to shore to get help, while the other occupant hung on to the vessel until the arrival of a good Samaritan who assisted. Vessel was later righted and towed to a nearby boat ramp. An inspection of the two bilge pumps revealed that both pumps were faulty which was the cause for the vessel to capsize.
