A 6FT 9INS businessman from Yorkshire has crossed the Mersey in a way no-one else ever has.
Graham Boanas, 43, became the first person to wade across the river and his towering achievement will help raise thousands of pounds to help children suffering from a debilitating skin condition.
Mr Boanas has previously waded the River Humber near his home in Hull and began his crossing of the murky Mersey from the saltmarsh at Ince Bank, near Ellesmere Port, early on Saturday morning.
He reached Oglet Shore, near Liverpool John Lennon Airport, on the opposite bank in just 48 minutes 38 seconds.
Despite the reassurance of his back-up team from the Humber Rescue service, using a helicopter and a hovercraft, at one stage he feared he would be washed away with the tide, which forced the water right up to his chest.
But the father-of-two, who runs an electronics company, says he took strength from thinking about the youngsters his challenge was undertaken to help - those with epidermolysis bullosa (EB) which makes their body erupt in blisters and sores.
After emerging on the Liverpool side of the river covered in thick black slime, he said he was raring to get going on his next challenge.
That will mean a return to the Humber for a walk underwater wearing lead weights.
Mr Boanas is hoping his Mersey crossing will have raised £100,000 for DebRA, which supports children with EB, who are known as 'butterfly children'.
