A rather unusual boat from Norfolk will be exhibiting at this week's London Boat Show.
David Williams from Horning is celebrating 50 years of an adventure he had in his own invention, the pedal boat.
Called 'Cyclone', David trialled it on his honeymoon around the Norfolk Broads.
In the summer of 1968, he and a friend decided to pedal around the Isle of Wight.
A journey of 40 miles that took them 12 and a half hours to complete.
David, who is now in his eighties still builds boats at his workshop on the Broads. His son-in-law Stephen Pitkethly, is taking 'Cyclone' to the London Boat Show to celebrate her half Century.
