David Fairhall, Penny Bowles and Jack Knights cover the 1967 Off-shore Powerboat Race.

"It's like riding a runaway bull bare-back". That is how one competitor described the International Powerboat Race from the Isle of Wight to Torquay. What attracts so many rich sportsmen to this 200-mile test of physical endurance? Are five hours of battering in big waves and the risk of serious injury worth the winner's prize of £1,000? Does this kind of race experience produce better powerboats for the family buyer? For the inside story of last Saturday's high-powered struggle off the south coast, join test pilot Peter Twiss at the helm of BBC-2's own entry, the Fairey Huntress Waterline.
