What’s been your biggest wipeout and hold down?

I was surfing at Mavericks and a big wave broke over me and i got held down for 25 seconds. I eventually made it back up to the surface by pulling my vest which inflated with air and allowed me to float back up.
 
Transcript: "My biggest, why pod and hold down was at Mavericks, San Francisco basically took off on this wave and I was a little bit late on it and a wind past vertical, there's probably like a 35-foot wave, the nose of my board dug into the water and I fell forward and I body surfed on my back down this huge wave. And I remember looking up in the and the lip coming over me and I was inside this mess. Of barrel at broke over me and then what happens is, as the wave sucks is like a Vortex and it sucks, suck me up. And it was this long moment of Stillness sucking up and up and up. And then I went over with the lip and then it did. I hit the impact and was so violent in the wave. Pushed me really deep under the water and it Mavericks, the waters cold and dark. It's more dense. So, it pushes you deeper. I just pulled me down Into the Depths and called me under for about 25. S, i was pressed on the floor on the ground just with what felt like the weight of the entire ocean pushing me down and I pulled my vest. So my inflation based. So it filled me up with air eventually. Let me go came up and luckily there wasn't another big one after that."
