Solo round the world yachtsman Alex Thomson performs a daring feat on board his high-speed yacht, HUGO BOSS. Thomson climbs up the 30-metre high mast of the moving vessel and dives into the ocean. This is not the first stunt we've seen from Thomson. Two years ago he completed The Keel Walk, a stunt which has become famous across the world.
