CAPE CORAL, Fla.- Cape Coral Fire Department personnel responded to a boat fire Thursday, at 4900 Nassau Court. An observant neighbor noticed smoke coming from the vessel and called 911.

The boat involved was a 42-foot, fiberglass hull, twin engine, sports fisherman boat, that was unoccupied at the time of the fire.

First arriving units reported heavy black smoke inside that was seeping out of the vessel hatches and windows. The interior of the vessel sustained both fire damage and severe smoke damage.

Both the Cape Coral Fire Department Investigators and the State Fire Marshal were on scene, but the cause of the fire remains unknown.
