HAMPTON BAYS - A fishing captain who spent most of his life at sea was killed yesterday when his vessel overturned in the waters off of Hampton Bays.

Officials say 85-year-old Stian Stiansen's boat was just east of Shinnecock Inlet when it capsized yesterday afternoon. The East Quogue man was found on the beach and pronounced dead.

Stiansen's friend and deckhand, 42-year-old Scott Finne, of Eastport, was rescued after he was found clinging to a floatation device.

Finne says the choppy waters churned up several powerful waves that knocked Stiensen's 45-foot fishing boat upside-down. "I saw the wave come," Finne tells News 12 Long Island. "I hollered forward, but I don't know if he heard me or not. Not that he could have done anything."

The two had been fishing for fluke and flounder all day before the boat, called “Pauline Four,” overturned.

The U.S. Coast Guard had issued a small craft warning before the incident, but officials say it wouldn't have been a concern for experienced mariners. The capsizing remains under investigation.

Friends say Stiansen made his living on the sea for nearly 70 years, and he was known as a legend in fishing circles on the East End. His family says he died doing what he loved.
