In stormy onshore peaks at Ocean Beach, Slater was able to out-surf the Brazilian duo of Medina and Pupo to claim his round 4 heat, book a spot in the quarterfinals, and mathematically clinch his unheard-of 11th world surfing title.
Consider two representations of two very big waves, below. The first is a photograph of Mike Parsons at Cortes Bank. The second is a video of Garrett McNamara near Nazare, Portugal. Now take out some measuring tape and make the distance of one foot between your hands. That's the amount, according to the Billabong XXL committee, that McNamara's wave is bigger than Parsons's wave.
