RedactedNarrative: Vessel 1 was tied to the dock with two Occupants on board when the Occupants observed smoke coming from the engine compartment.  Shortly thereafter, the fiberglass on Vessel 1 caught fire, at which time the Occupants left Vessel 1 and the Owner/Occupant untied Vessel 1 from the dock.  When emergency services arrived on scene, Vessel 1 was fully engulfed in flames and the wind had pushed Vessel 1 along the north shoreline heading east.  The fire department was able to extinguish the fire.  Electrical failure was the cause.
