Sailor Chris Jacks sets off on round-Britain voyage
A yachtsman has set off on a voyage to sail solo around mainland Britain.
Chris Jacks, who departed from his home port of Liverpool on a vessel named Roma, expects his journey to last for seven weeks.
The 30-year-old will travel in an anti-clockwise direction and said it was part of his preparations for the round-the-world Golden Globe Race in 2018.
The sailor, who aims to stop off at 16 ports around Britain, added: "You only live once so what a thing to do."
He said that his biggest challenges would include navigating through "the busiest shipping lanes in the world in the English Channel, and fishing trawlers up and down the east coast and in the Irish Sea".
He also aims to sail across the Atlantic in 2017 before setting off on the Golden Globe Race, which will mark 50 years since the first non-stop sailing race round the world, eventually won by the British adventurer Sir Robin Knox-Johnston in 1969.
In autumn 2014, Mr Jacks reached the summits of the 92 Lake District peaks in 40 days.
He also slept alone on Fleetwith Pike in Cumbria from Christmas Eve last year to New Year's Day to raise money for Alder Hey Children's Charity.
