An exclusive set of pictures have been released of the yacht that capsized in the mid-Atlantic Ocean, with four British crew members reported missing.
The Cheeki Rafiki yacht was pictured during its Antigua Sailing Week regatta.
Yachting experts expressed concern that the hull of the yacht had been found but not inspected. Andrew Pindar, who runs the GAC Pindar racing team, said "The fear with yachts upside down is that people could be trapped inside them".
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.
