Garrett McNamara breaks biggest wave surfing record AARON COHEN · JUN 14 2012
Garrett McNamara rode a wave off of Nazare, Portugal last November that some surfing experts billed at 85-90 feet. This would have smashed the world record wave height of 77 feet held by Mike Parsons. However, last month, after judges compared "McNamara's height in a crouch and the length of his shin bone with the wave's top and bottom," the Guinness Book of World Records decided the wave was 78 feet and gave him the record. To get a feel for McNamara's feat, go find an 8 story building and imagine riding down it on a surfboard.
And here's another nice surfing video.
