The US Coastguard resumed its search for four sailors approximately 1,000 miles (1,600 kilometres) east of Cape Cod, Massachusetts on Tuesday.

Upturned yacht hull

The 305m container ship Maersk Kure located and captured an image of the capsized hull of what is presumed to be the 39ft sailing vessel Cheeki Rafiki, May 17, 2014. The capsized vessel was located 1,000 miles east of Cape Cod, Mass., within the search area. Due to the ship's massive structure, 4.5m sea conditions, and amplifying weather, they were unable to retrieve the sailing vessel. They did not identify any other debris or signs of the missing crew.

The crew of four aboard British registered Cheeki Rafiki, a Beneteau First 40.7 yacht from Southampton, were last heard from at 5:30am (BST) Friday 16 May when US Coastguards were alerted to two 406MHz personal locator beacons.

The vessel had already reported a leak onboard and had altered course for the Azores.

Rescuers reported seas at the time were 4.5m with winds surpassing 50 knots. The air temperature was 15°C and the water was 15.5 degrees.

The Coastguard called off the search on Sunday May 18, following a report on Saturday, that the 1,000ft cargo ship, Maersk Kure, had located an overturned hull that matched the description of the Cheeki Rafiki, but no sign of the sailors.

A petition was launched and appeals from family and friends repeatedly called on authorities to restart the search.
