Sailing is one of Great Britain's most successful Olympic sports – thanks to this island being one of the windiest in Europe. We've won the most gold medals of any country in the world in Olympic sailing events – 25 in total – and the second most medals overall after USA.

RIO 2016 OLYMPIC SAILING – THE EVENTS & COURSE
There are eight disciplines at the Rio 2016 Olympics:
470 - Men's
470 - Women's
49er - Men's
49erFX - Women's
Finn - Men's
Laser - Men's
Laser Radial - Women's
Nacra 17 - Mixed
270 sailors from 62 countries will be taking part in the events – which vary from single handed and double handed boats.

The sailors have to complete the race powered only by the wind, adapting to the wind and weather conditions in order to succeed.
