Andrew Halsey is reported to have suffered four seizures

Andrew Halsey, 45, from Clacton, Essex, was rescued by a fishing boat last week after capsizing 18 times in 36 hours in gale force storms.

The former London bricklayer remained optimistic about future attempts despite hitting the record books during the journey for covering the least distance in the most time at sea in a rowing boat.

On Friday at a news conference in Colchester, Mr Halsey said: "I will do another ocean, definitely.

"I do intend doing the Pacific again, but whether that will be my next voyage I don't know. I intend to do all the oceans anyway."

Andrew Halsey was rowing to Brisbane, Australia

Mr Halsey set off in his 25-foot boat the Brittany Rose from Callao, Peru, on 25 November.

His destination was Brisbane, Australia, about 8,000 miles away.

Last week he was caught in huge waves of between 40 feet to 50 feet, eventually hitting some wreckage.

He said: "The boat was hit and capsized. For almost four hours I was trapped upside down, water was up to my chest.

"I have been in worse storms, but with this one it was coming from different angles and was difficult to deploy a sea anchor. I feel relieved I got out with my life."

'Got out with life'

Four hours after he launched an emergency beacon a United States plane dropped him a VHF radio, which he could not reach, and a life raft which he used to stop the boat capsizing.

About 15 hours later, about 800 miles from the Galapagos Islands, he saw a light on the horizon and launched flares.

He was picked up by the Chinese boat, but its crew was unable to save his vessel.

He was later transferred to a US coastguard vessel Munro.

Mr Halsey rowed the equivalent of about 4,000 miles but was only 2,000 miles from his starting point when he was picked up, due to tides and currents.

The adventurer was the first disabled person to row the Atlantic in 1997, suffering two epileptic seizures during the voyage.
