Here are some stills of him in various right points around the globe...
Richard Safady was the first hull rider I knew of who starting knee riding his stand up boards, then evolving into laying down. I'm not sure when Roger started relative to Saf, but I think is was after.
I built a 9'4'' Greenough/Simmons last August, with the intention of riding it standing up, kneeling, and laying down. It's been a boon for me, because I hate riding mats in small, crowded lineups. Over time, I pretty much got into riding prone all the time in those conditions. It goes on nothing!
Here's an odd little video of the board. I picked up a foot high wall of whitewater in the shorebreak and rode it onto bare sand. Even when it was down to 3'' or 4" high, the board just kept going...
