Here's a few interesting comments from the surfers in that pic.
"Towner was towed into a solid one during last week's swell at Teahupoo and looked up to see local Tahitian and former World Tour competitor Vetea "Poto" David dropping in on a stand-up paddleboard. "Every time I go out on my stand-up paddle, every time I see a ski, I just let them know: 'Be careful. I'm gonna drop in on you,'" explains Poto. "Some waves you can't get on your stomach or paddling, so we have the priority compared to them (tow-ins) -- 'cause they can go so deep."

This is what Laurie Towner had to say..
"I was definitely scared when I saw it coming down the face 'cause it's such a big piece of foam," Towner recalled. "Then I realized who was riding it and figured we both could make it! Once the wave spat everything disappeared but the foamball gave me speed so I took the low line -- 'cause I figured if I didn't, I'd run straight into him. That's when I came out of the barrel, our rails briefly touched, we pulled out and shook hands -- it was a fun ride!"
It's great to see the surfers and SUP surfers getting along..

.. Anyone know what Naish board that is that he's on?
