Jason Momoa is recalling a scary surfing incident in Hawaii ... he says he almost drowned in 10-foot waves.
The "Aquaman" star was on the "Smartless" podcast with Will Arnett, Jason Bateman and Sean Hayes when he told the story of his near-death experience while doing a grueling open-ocean paddle off the coast of Maui.
Jason says he was on a 13-mile paddle near the famous Jaws surf break with big-wave surfers Laird Hamilton and Dave Kalama in 2007 when, halfway through, his leash snapped and the wind pushed his board out of sight.
