Fra rapidmag:Before kicking off the African Revolutions Tour in January, Bradt worked with the Department of Physics at Lewis and Clark College in Portland, Oregon,on its study Impact Forces Associated with Whitewater Kayaking. This study uses data from NASA and an accelerometer within a kayak to calculate the G-forces acting on the human body off of a variety of waterfalls.The researchers say the vertical waterfall limit physically possible in kayaking is 186 feet (60 metres), taking into account current safety equipmentand gear. ?Of course there are a lot of variables to consider, but theoretically we could push this beyond 266 feet,? Bradt laughs sinisterly. ?Our equipmentand boats just aren?t there yet.?On his Revolutions Tour Bradt is testing under-seat suspension to absorb impacts and an implosion-proof skirt using a cable-release system. ?It?s a progression we need so we can achieve another level of safety for everyone, not just guys running the big stuff,? Bradt says. ?Obviously there?s a lot of quirks and limitations but we need to discover those so we can usher in a new stage of development for creeking.??Neil Etienne
