RedactedNarrative: On Sunday, March 29, 2020 at approximately 03:40 p.m, I responded to a complaint of a sailboat that was on fire. The vessel was located at a marina in Mill Creek. Upon my arrival, I observed a white sailboat bearing Maryland registration (MD-7341-CE). I observed thick white smoke above the sail boat and Solomons Fire Boat #3 suppressing the fire with foam. I detected the odor of burned fiberglass. The owner of the vessel, Owner 1 stated that there was smoke coming from the cabin of the sailboat after he started the engine. Owner 1 and Owner 2 used three B1 fire extinguishers in an attempt to put out the fire. A neighbor called 911 after seeing the smoke. Owner 1 also stated that he had just finished replacing the battery to the vessel. He advised that the sailboat did not leave the slip. Solomons Volunteer Fire Department Engine #33 arrived on scene at approximately 03:25 p.m. and successfully put out the fire. I interviewed Owner 2 and was able to obtain a written statement from her. The Fire Marshal determined the cause of the fire to be an electrical short. The vessel remains floating in it's assigned slip. No injuries were reported. No violations. This case is closed. All events occurred in Calvert County, MD.
