RedactedNarrative: On 4/3/18, at approximately 1848 hours, a single vessel incident occurred on the south side of Lake Harney, in Volusia County Florida. The vessel (V-1) was under power when the engine area caught fire for an unknown reason, as V-1 reached shore. The two occupants abandoned the vessel and went ashore leaving V-1 adrift and on fire. V-1 burned to the waterline and self-extinguished. No injuries occurred in this incident. State Fire Marshal Investigator was advised of the incident and responded to the scene during the recovery of the vessel to conduct an inspection (Report in attachments). The investigator concluded that the evidence suggests that the fire started in the engine area and was likely electrical in nature. The cause of the fire is found to be "accidental".
