RedactedNarrative: OP1 stated that he was unaware how the vessel began to take on water. He stated he was cruising across the bay when his vessel started to swamp and feel heavy in the rear end. OP1 stated by the time he realized how much water was in the boat and take action, waves caused the boat to slowly sink and turn over. I asked OP1 he his bilge pump worked and he stated "yes it works well" I asked him if he forgot to put the plug in? He stated that he remembers putting it in before he put the vessel in the water. 
  
   Afterwards I requested a tow boat through dispatch. Once the tow boat arrived the occupants where transferred to the tow boat and the vessel was towed to shore
