The first man to sail single handed non-stop around the world has told ITV News he believes the search for the missing British yachtsmen should resume.
Sir Robin Knox-Johnston said: "We must assume that they probably got into the life raft - if so they are probably still in it.
"My view is that actually we should have another shot at finding them".
British Olympic champion Sir Ben Ainslie and Sir Richard Branson have also shown their support on Twitter for the four yachtsmen.
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.
