On the North Shore of Maui, giant ocean swells slam into a uniquely-shaped reef and create one of the most massive waves on earth known as Jaws. The world's elite surfers flock to Jaws to take on 50 to 60-foot monster waves.
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.
