Garrett McNamara has ridden what may be the highest wave ever caught by a surfer, reportedly 100 ft (30 m) high.
Garrett McNamara surfed the wave on Tuesday off the coast of Portugal, in the same spot where he surfed the current world-record wave of 78 ft (24 m) in November 2011.
Experts will now have to certify the new record.
The giant wave formed above an underwater canyon famous for being the world’s biggest wave generator.
“You are just going so fast,” Garrett McNamara told ABC television.
“It’s really, really similar to snowboarding on giant mountains.
“And you’re just chattering, flying down this bumpy, bumpy mountain. Your brain is getting rattled. Your whole body is getting rattled.”
He said he was relieved to have avoided a rocky section of the coast.
Garrett McNamara began surfing at 11 and turned professional six years later.Garrett Mcnamara, giant wave, highest wave, nazare, portugal
