RedactedNarrative: Vessel 1 was trolling with four persons on board when the Operator left the helm to check a fishing line.  In doing so he noticed that water was coming in the starboard scupper and that the bilge was not working properly.  The Operator then tried to start the main engine and it would not start.  The Operator tried putting in a new battery but was still unsuccessful in gettting the main engine to start.  The Operator instructed everyone on board to don a PFD as Vessel 1 then submerged; Vessel 1 then capsized sending all four Occupants aboard into the water.
