The search for the four sailors on board the yacht Cheeki Rafiki will be suspended if nothing is found by Friday night, the US Coast Guard has said.
The Cheeki Rafiki, based in Southampton, was sailing back to the UK from Antigua when it went missing.
The search for the vessel was originally called off on Sunday but resumed on Tuesday.
The search has so far been focused on an area some 1,000 miles east of Cape Cod, Massachusetts.
