Hampshire sailor Alex Thomson has performed a daring feat by climbing the top of this high-speed yacht and diving into the ocean - all whilst the yacht was sailing at a 60 degree angle.
The 39-year-old is keen to find new ways to use his yacht and has been planning this trick for months beforehand.
The stunt was performed on the Spanish coast near Cadiz and in case of emergency a medical team remained near by and driver sailed alongside the yacht.
