For more than 60 years, the Hawaiian island of Oahu has beckoned surfers hoping to drop into some of the world’s biggest waves. The result has been many epic rides, all kinds of brutal wipeouts, and the occasional harrowing rescue. In each case, the experience and skills of those involved can make all the difference. And of course, there’s sheer luck. In this replay of one of our favorite episodes from a couple winters ago, we hear the story of a young lifeguard who set out to prove himself in the legendary swells of Sunset Beach, followed by the tale of a hard-charging North Shore local who started training surfers to save each other, only to find himself in desperate need of a rescue.
