For centuries, mariners have spun tales of gargantuan waves, 100-feet high or taller. Until recently scientists dismissed these stories—waves that high would seem to violate the laws of physics. But in the past few decades, as a startling number of ships vanished and new evidence has emerged, oceanographers realized something scary was brewing in the planet’s waters. They found their proof in February 2000, when a British research vessel was trapped in a vortex of impossibly mammoth waves in the North Sea—including several that approached 100 feet.
As scientists scramble to understand this phenomenon, others view the giant waves as the ultimate challenge. These are extreme surfers who fly around the world trying to ride the ocean’s most destructive monsters. The pioneer of extreme surfing is the legendary Laird Hamilton, who, with a group of friends in Hawaii, figured out how to board suicidally large waves of 70 and 80 feet. Casey follows this unique tribe of people as they seek to conquer the holy grail of their sport, a 100-foot wave.
