Sean Morley has modified his kayak to make his journey comfortable

Sean Morley, battled 8-foot (2.4 metre) waves in a near 12-hour voyage from Rathlin Island, off Ireland, to Machrihanish Bay on the Kintyre coast.

The 38-year-old traffic police officer from St Erth has completed 79 days and 2,160 miles, but is a week behind schedule because of a back problem.

He temporarily stopped his bid after aggravating an old injury in Ireland.

'Armchair comfort'

He tweaked his back reaching for a cup of tea on 2 June and needed treatment before he could continue.

He has now modified the seating of his kayak with expanded foam to create "armchair comfort" for the rest of his voyage.

His journey, scheduled to last six months, began in Falmouth in Cornwall on 3 April.

His route is taking him on the seaward side of every inhabited island that makes up Great Britain and Ireland.

They include: the Isles of Scilly, the Channel Islands, the Orkneys and Shetlands, as well as the remotest corner of the British Isles, St Kilda - the isolated Atlantic outpost 41 miles west of Benbecula in Scotland's Outer Hebrides.

A former member of the Great Britain kayak racing team, Mr Morley has already had a close encounter with the sharks near the Aran Islands on the west coast of Ireland, and met the self-styled "king" of an Irish island.

He has already completed several record-breaking paddles, including a crossing of the St George's Channel and a 500-mile circumnavigation of Scotland.

His current trip is raising money for the RNLI and the Marine Conservation Society.
