The families of crew from the missing UK yacht Cheeki Rafiki have spoken to the media before a meeting at the Foreign Office.
The vessel was sailing back to the UK from a regatta in the Caribbean, when it started taking on water.
The relatives said they hoped satellite imagery would be released so that it could be studied by members of the public.
