Investigators said they have yet to find the precise cause of a Brookings Harbor fire Monday morning that heavily damaged the Miss Pacific, an 85-foot commercial fishing vessel. “The cause is undetermined,” Harbor Fire Interim Chief Thomas Sorrentino told The Pilot. “We believe it could be an electrical issue. “The fire started on the port-side rear of the cabin and went out the back to the stern of the boat, which caught the net reel on fire.” Sorrentino could not estimate the financial damages to the vessel. Witnesses said someone from nearby U.S. Coast Guard Station Chetco River spotted the flames and began alerting adjacent boat operators. Two Coast Guard boats maneuvered to the fire scene and crews began spraying water on the burning vessel.
