RedactedNarrative: On April 08, 2013 at approximately 12:00 hours I observed a Jacksonville Fire Rescue(JFRD) vessel pass me operating with its lights and sirens on. I made contact with my dispatch center to see if they needed assistance. Dispatch advised me there was a sailing vessel on fire in the anchorage of Mulberry Cove Marina located on NAS Jacksonville.  
   I arrived on scene at 12:25 and the fire was out, and I was advised by base police that no one was on board. JFRD towed the vessel to B dock, the nearest dock at Mulberry Cove and continued to spray water on a leaking propane tank. Once the vessel was secure, JFRD turned it over for investigation.
   I called my Lieutenant for assistance,as the cause of the fire was not immediately known. The Naval Criminal Investigative Service (NCIS) and the State Fire Marshal's office, also came to investigate.
   The cause of the fire is still unknown. NCIS took over the investigation and will file any charges pending their outcome.
