Aghnaanga showed signs of hypothermia when rescued, the Coast Guard said. The captain of the fishing boat that brought him aboard, Adam White, told local station KTUU-TV that the teen had clung to the skiff through darkness and water temperatures around 50F (10C).
"That's one tough kid," White said. "Through the teeth chattering, he had mentioned that his brother was still under the skiff. And then he said that, in the previous night, before our rescue, that his cousin had slipped away."
The trio had departed from St Lawrence Island on Friday 4 September and were expected back the following Sunday afternoon, the Coast Guard said. When the boat failed to return, a search was launched. The vessel capsized on Saturday, leaving Aghnaanga without food or water for two days at sea, his mother Vina Kulowiyi wrote on Facebook.
Kulowiyi, the mother of Aghnaanga and his older brother, said her sons were doing what they loved: fishing to provide for members of their community who do not always have access to meat at their local store.
"Our hearts go out to the families, friends, and communities affected by the tragic loss of these two mariners," said Rear Adm. Bob Little, commander of the Coast Guard's Arctic District.
