of steel. World class surfer maya gaberra cuts through waves like a hot knife through butter. She is searching for bigger swells. We decided to send ginger zee, one of the most fearless members of the "gma" staff -- yeah, she cuts through weather like a hot knife through butter. It was a real wakeup call. I'm not good, is what she's saying. Imagine standing on a building 15 stories tall and then surfing a wave to the base. She holds several world records. I, as you'll see, don't. Plunging into some of the most colossal waves on the planet, she's a brazilian knockout. And a world record-holding surerring named maya. Something that maybe 0.5% of all surfers in the world do. Reporter: It is tow-in surfing. This 26-year-old phenom holds nothing back. She drops in, at least 45 feet high. Terrifying to most. We collaborate on the forecast.

Just when I thought it was impossible. Start paddling. ♪ Reporter: I'm up. Every so briefly. Maya says we can count it. All right. We did it? In my defense, she had trouble surfing that day, too. It was a tough day. She's come back from several injuries over all her travels. I asked her what she would do if she didn't surf, she wants to be a sports broadcaster. I think she would be better that this than I was at her sport. It was 3 1/2 hours we were out there trying. We want to see this shot one more time. I just ke-- I just kept -- it was -- the quickest surfing trip ever. Good job. Thank you, ginger. Known as one of the most
