MONTAUK, N.Y. - A Coast Guard crew from New Jersey joined others from the Northeast in an effort to rescue a lobsterman after he fell overboard yesterday from his boat more than 40 miles off Long Island.

The Coast Guard Cutter Sailfish from Bayonne joined other search crews from Massachusetts, Rhode Island, Connecticut and New York to search for John Aldridge, the Coast Guard announced last night. The search area spanned more than 780-square miles.

Aldridge spent more than eight hours in the water until he was found and rescued by a Coast Guard Air Station Cape Cod Jayhawk helicopter. He was found 36 nautical miles south of Montauk, N.Y.

Aldridge told the Coast Guard helicopter crew he used his rubber boots to keep him afloat until he could swim to a buoy. He's being treated for dehydration, exposure and hypothermia at a hospital in Falmouth, Mass.
