The Kodiak Daily Mirror reported that the man who died was Cody Cecil, 30.
Police and emergency rescuers on Wednesday responded to St. Herman's Harbor in response to a report of a refrigeration leak aboard the Alpine Cove.
Cecil and Francis Rutten, 56, of Snohomish, were rushed to Providence Kodiak Island Medical Center. Three others were also evacuated from the boat.
Police say Cecil was pronounced dead and Rutten is being treated for exposure to Freon, a gas used as a refrigerant.
The Kodiak harbormaster ordered the evacuation of nearby vessels.
Kodiak police and the Coast Guard's Marine Safety Detachment are investigating.
