BOOTHBAY, Maine (AP) — A spectacular fire Friday destroyed a boatyard that turned out commercial fishing boats, tugs, barges and ferries on the Maine coast.

The 50,000-square-foot building at Washburn & Doughty Associates was rocked by a series of explosions as flames ripped through the facility. One firefighter was treated at the scene for heat exhaustion.

Gov. John Baldacci put the property damage at $30 million.
