RedactedNarrative: Vessel 1 was underway in a northwestern direction from Chittenango Creek. Operator reports hearing a loud explosion while cruising at approximately 20 mph. Operator looked towards the engine compartment and saw flames coming from the engine. Operator states that he immediately retrieved PFDs and gave one to his wife. He then attempted to use the fire extinguisher but it was unsuccessful at extinguishing the fire. Operator states that he called 911 and tried to report the fire but the flames became too large. He and his wife entered the water and swam safely away from the boat. Both swimmers were retrieved by good Samaritans boaters and stayed on-scene until the Fire department arrived. Vessel 1 was extinguished and ultimately sank. It was marked with a buoy and later retrieved by an unknown salvage company.
