​1 dead, 3 rescued after tugboat sinks off NY's Fire Island

FIRE ISLAND, N.Y. -- One tugboat crew member died and three others were rescued Saturday when their boat sank in icy and stormy waters about a mile off Fire Island, authorities said.

One of the crew members managed to make a cellphone call to the Coast Guard at about 2 p.m. as the tugboat Sea Bear was sinking, said Coast Guard Petty Officer Morgan Gallapis.

"They had only seconds to let us know before they sank," Gallapis said.

Three male crew members in immersion suits were rescued by the Coast Guard from the water a mile off a section known as Fire Island Pines, Gallapis said. Fire Island is a long, skinny barrier island that hugs the south shore of Long Island.

Three Coast Guard boats, a helicopter, two other tugboats and Suffolk County Police Marine Bureau boats all searched for the fourth crew member, authorities said. Suffolk officers on the beach assisted in the search.

Coast Guard Command Duty Officer Mark Averill said the man's body was found shortly after 5 p.m.

The victim, who was not immediately identified, was not wearing an immersion suit, Averill said.

"The water temperatures are extremely cold this time of year," Averill told CBS New York. "And if you enter the water, we have a functional time, which means the person could only possible swim for about 1.6 hours without the immersion suit."

Gallapis said the three men who were rescued were treated for hypothermia at the Fire Island Coast Guard station but otherwise had no physical injuries.

She did not know what caused the boat to sink, but the accident occurred during a storm. Suffolk County police said inclement weather prevented their aviation officers from flying and police Marine Bureau boats were hampered by heavy ice in the water.

The petty officer said the tugboat that sank was among three heading back to their New York City base after completing a project on Long Island.

"This tug was in the back of the line when it sank," Gallapis said. "The other tugs continued without seeing them. They heard the distress call and headed back to assist in the search."
