The Friday File: Last month, a team of wave engineers determined that Brazilian big wave surfer Maya Gabeira, assisted by her tow-partner Sebastian Steudner, who was sea-dooing at 50 mph while slinging her onto the lip of the giant wave, rode the biggest wave of the year. It was 73.5 feet high! This is the first time a woman has held this title. The biggest wave ever ridden, 78 feet.
