In this seemingly implausible photo we see Alex Thomson performing what he calls the ‘keel walk’, a stunt that has become infamous in the sailing world thanks to this photograph. As his 8-tonne carbon fibre yacht, Hugo Boss, sails on edge, Alex pulls up in a 255-horsepower ski jet and leaps onto the keel of the boat. Be sure to check out the embedded video below for proof of this epic feat. Alex Thomson, the Sifter salutes you.
