A U.S. Coast Guard helicopter this afternoon medevaced the 61-year-old captain of the fishing vessel Sea Bird.
The 167-foot vessel was far out in the Gulf of Alaska, 253 miles southeast of Kodiak.
The captain, whose name was not released, was reported to be suffering "symptoms of gastrointestinal distress," a Coast Guard press release said.
He was taken to a hospital in Kodiak.
A Coast Guard C-130 aircraft accompanied the helicopter, which was operating at the edge of its range.
Sea conditions on the scene were calm.
The Sea Bird's chief mate will bring the vessel into Kodiak, the Coast Guard said.
The boat's hailing port is Seattle.
