RedactedNarrative: Owner awoke choking due to on board fire.  Vessel had been at anchor for 4+ hours at night.  Aux. generator on aft deck was running with power cable plugged in to shore power outlet.  Only items energized by said generator and/or on board batteries were a boat battery charger and a 12 volt ice box.  Owner jumped overboard and climbed in to a drifting inflatable dingy where he called 911 and where a Good Samaritan came to his rescue.  Vessel later sunk while fire was being fought by responders.   Owner was treated at a local hospital for smoke inhalation and later released.  36 hours after the fire he was still suffering from difficulty breathing, a scratchy throat, and then reported back pains possible caused when jumping off the burning boat, swimming to the dingy, or when boarding the dingy.
