Solo round the world yachtsman Alex Thomson performs a daring feat on board his high-speed yacht HUGO BOSS: He climbs up the 30-meter high mast of the moving vessel and dives into the ocean - That's the Mast Walk.

This is not the first stunt we’ve seen from Alex – two years ago he completed the “Keel Walk”, a stunt that has become famous throughout the world.
