In a statement the Coastguard say the warship diverted to the location and deployed a boat crew and surface swimmer to assess the boat. The surface swimmer confirmed the name on the ship was Cheeki Rafiki and went in the water to investigate further.
The swimmer determined the boat's cabin was flooded and windows were shattered, contributing to the complete flooding inside. The swimmer also knocked on the hull and reached an arm's length below the waterline with no results.
The US Coastguard says a US naval ship searching in the Atlantic has found the hull of the Southampton yacht, Cheeki Rafiki. They located the boat a week after the vessel and her four-man crew went missing on a voyage back from the Caribbean.
A Navy diver has confirmed the name of the yacht and has banged on the hull to see if anyone is inside. The cabin of the boat appeared to be flooded. They have not found the yacht's life raft.
Relatives of four missing sailors have been meeting at the Foreign Office to discuss the search for their loved ones.
The crew of the Cheeki Rafiki raised the alarm that they were in trouble last Thursday and haven't been seen since.
The US Coastguard has said it may call off the search if it does not find anything by 5am tomorrow morning.
The sister of one of the sailors missing in the Atlantic says she's disappointed the search for the crew will end tomorrow morning. Steve Warren and Paul Goslin from Somerset were on board the Cheeki Rafiki when contact was lost a week ago.
Today the US Coastguard announced if no new leads were found before then, the search will end for the final time. Kay Coombes is the sister of Steve Warren ...
The Foreign Office has released this statement on behalf of the families of the missing sailors:
The Foreign Office has issued the following statement over the missing crew of the Cheeki Rafiki.
"The families of James Male, Andrew Bridge, Paul Goslin and Steve Warren still hold out much hope that their loved ones will be found soon.
"They have received so much support from the public and the yachting community, hearing endless stories of people that have survived many weeks and months in different circumstances at sea and have drawn much strength from this.
"They were obviously saddened to hear that the US Coast Guard will be suspending the search. But, they were prepared for the fact that this would have to happen.
"They are meeting with the Foreign Office later on today, to talk about UK involvement and any other avenues that can be explored."
Captain Anthony Popiel says the search for four missing British sailors will be suspended if there are no further developments which locate the crew of the Cheeki Rafiki by midnight tomorrow.
The last picture of the four missing British sailors has emerged - showing them just hours before they set off for home. 52 year old Steve Warren and 56 year old Paul Goslin from Somerset are seen leaving an awards ceremony at Antigua Sailing Week. Just hours later they went missing.
