ANCHORAGE, Alaska (AP) – Four crew members of a fishing boat were found alive Wednesday, hours after their vessel was reported in distress in chilly waters off Alaska’s Aleutian Islands, a Coast Guard spokesman said.

The bodies of two other crew members have also been found, and a search continues for the five remaining crew members of the Katmai, a 93-foot fish processor based on Kodiak island, said Coast Guard Petty Officer Levi Read.

The four survivors were being flown in a Coast Guard helicopter to Adak Island, about 1,300 miles southwest of Anchorage, Read said. They were discovered about 100 miles west of Adak, he said. No other details were immediately available.

The Coast Guard received an electronic signal at 1 a.m. from the Katmai.

A search helicopter and C-130 airplane were sent from Kodiak, a journey of about 4 1/2 hours.

The plane crew spotted two strobe lights in the water and dropped two life rafts. But after sunup, the searchers had seen no sign of the Katmai or its crew, Read said.

The Coast Guard did not receive a mayday call, but given the boat’s remote location, it may not have been heard.

“It’s hard to say whether they tried or not,” Read said.

One strobe was attached to an empty survival suit and the other was attached to a floating emergency beacon that can be triggered automatically by contact with water. Vessels are required to carry those devices to signal emergencies and aid searches.

The Coast Guard reported 10- to 15-foot seas in the area, with winds from the north at 34 mph. The area had a mix of rain and snow.

The Katmai was carrying a load of cod and was heading toward Dutch Harbor on Unalaska Island, Read said. Dutch Harbor is 800 miles southwest of Anchorage and about 610 miles southwest of Kodiak.
