Alex Gray and instructor, Scott Smith, get psyched before they charge the cold night for some lobster at Catalina off the Body Glove boat, the Disappearance. Well... mostly Alex gets psyched.
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.
