Surfer wins big with huge Hawaii wave

The contest is famous for its massive waves, and it's not even held unless the waves in the area are between around 10 - 12 metres high.

At 23, John John Florence is one of the youngest competitors ever to take the prize.

He won more than £50.000 after beating 27 other competitors.
