JUPITER, Fla. (AP) — Rescuers have endured a fourth night of an anxious search for two young Floridians who went missing on the high seas.

The Coast Guard scoured an area the size of West Virginia with no sign of the boaters by early Tuesday morning.

The 14-year-old boys' vessel was found capsized two days earlier. But relatives and friends of the teens were clinging to hope that the expertise they acquired boating and fishing in their short lives was enough to keep them alive while apparently lost in the Atlantic. They say the boys were born and bred as boaters.

Carly Black, the mother of Austin Stephanos, said she wouldn't even "bat an eye" about the boys' ability to survive at sea.
