The US Coast Guard said there has been no sightings of a life raft, debris, or a boat, since the search for four missing British yachtsmen has been renewed on Tuesday.
The search will continue with crews from the US, Canada and Britain participating in the operation.
U.S. Coast Guard Captain Anthony Popeil said that no decisions had yet been made on when to suspend the search.
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.
