(CNN) -- The U.S. Coast Guard's search for four British sailors missing in the Atlantic Ocean since late last week resumed Tuesday morning, the service said. The Coast Guard, in a statement, said the new search involved six ships and three planes, including a Canadian C-130. The search focused on an area 1,000 miles (1,600 kilometers) east of Cape Cod, Massachusetts. The 39-foot (12 meters) Cheeki Rafiki was sailing from the Caribbean to the United Kingdom last Thursday when it began taking on water, according to the yacht's managing agent. "Unfortunately, we lost contact during the early hours of Friday morning, and we believe the crew abandoned to the life raft," Doug Innes said in a statement on Sunday.
