The decomposing body of a British man trying to sail solo around the world has been found on his yacht as it drifted off the coast of Jamaica, according to officials.

Mark Brennan, 42, was reported missing Dec. 21 when all communication ended after he sailed across the Atlantic, according to alerts that described him as “a somewhat inexperienced sailor.”

His 30-foot yacht, named Avrio, was finally spotted adrift about 75 nautical miles off the coast of Jamaica late Monday and towed to the island, the Jamaica Observer said.

“Sad to say, a decaying corpse believed to be the boat’s captain, Mark Brennan, was found on board,” confirmed Boat Watch, a specialist maritime group that traces those lost at sea.

Northumbria police, the UK force leading the missing person case, told ChronicleLive that it had “been made aware that authorities in Jamaica have recovered a body on a boat.”

“A formal identification process is ongoing but it is suspected that the body is” Brennan, a spokesperson told the site.

“The relevant authorities in Jamaica are carrying out inquiries to establish the cause of death and we will continue to support their investigation.”

A spokeswoman for the UK’s Foreign and Commonwealth Office said it was “supporting the family of a British man reported as missing in the Caribbean.”
