Debris spotted last night in the Atlantic Ocean has so far been the only potential sighting in the search for the missing British yachtsmen.
Off the coast of the United States, planes and ships are preparing for another day scouring thousands of miles of sea.
ITV News correspondent Robert Moore reports from Boston, where that search is being co-ordinated:
With no sign of a life raft or of debris, and with nearly 20,000 square miles having been searched, the hunt continues for another day.
Veteran yachtsman Tony Bullimore tells ITV News that there is a "strong possibility" the yachtsmen are still alive in the life raft.
