There are waves, and then there are waves. Garrett McNamara managed to surf one of latter. The Telegraph reports that the Hawaiian set a world record after riding the 90-foot monster off the coast of Portugal. The 44-year-old professional surfer was in a prime position to do so: He was in the water as part of a study with the Portuguese Hydrographic Institute that's attempting to figure out why the rogue waves form in the area. The former record, set in 2008, involved a 77-foot wave. (More surfing stories.)
