( CNN ) -- A missing British yacht was found overturned with its keel broken , causing a breech in the hull , about 1,000 miles off Massachusetts , but the four-man crew is still missing , the U.S. Coast Guard said Friday . A U.S. Navy helicopter spotted the capsized the 39-foot Cheeki Rafiki sailboat within a Coast Guard search area east of Cape Cod , officials said . A Navy boat crew and surface swimmer assessed the damaged boat , but the swimmer found no signs of the crew after knocking on the hull and reaching below the waterline , the Coast Guard said . Search crews looked Friday for a bright-colored life raft and the missing sailors , who the Royal Yachting Association identified as skipper Andrew Bridge , 21 ; Steve Warren , 52 ; Paul Goslin , 56 ; and James Male , 23 . As expected , the Coast Guard suspended the search at 10 p.m . ET Friday -- which was midnight in the search zone -- after scouring another 21,000 square miles . No sailors had been found as of then . In a statement Friday night , the Coast Guard hinted that the prospects anyone would be found alive are slim . `` Based on the extreme sea conditions at the time of distress , but assuming best-case emergency equipment , the estimated survival time past the time of distress was approximately 20 hours , '' the Coast Guard said . `` Searches were suspended nearly 200 hours after the time of distress . '' The four British sailors have been missing in the Atlantic Ocean for more than a week . The 39-foot ( 12 meters ) Cheeki Rafiki was sailing from the Caribbean to the United Kingdom on May 15 when it began taking on water , according to Doug Innes , the yacht 's managing agent . Innes said contact was lost with the boat -- which he describes as `` a performance racer/cruiser '' that is `` equipped for trans-Atlantic sailing and racing '' -- early the next morning . He added that he believed the crew abandoned to the life raft . But the U.S. Coast Guard appeared to dispel that notion , saying Friday night that `` the boat 's life raft was secured in its storage space ... indicating the crew had not been able to use it for emergency purposes . '' Multinational search for missing British yacht crew resumes . CNN 's Greg Botelho , Steve Almasy and Kevin Conlon contributed to this report .
