You may not be aware of this, but there are folks down on the Texas coast who will surf the wave in the wake of tankers for as long as 15 or 16 minutes. I'm sure if you're into things that are Zen, then this must be a very Zen thing. It's quirky, but it quite fits Texas, I find. True, there's a great tradition the world 'round for surfing, but these guys have probably done it in a cowboy hat, and I suspect at least one of them has played bongos naked. Yeah, very Texas, that.
This is a commercial for a sportswear label, but you get a good idea of tanker wave surfing. Good stuff. Also, if you have a little more time, you don't have to be a surfer to appreciate the superb surfing film Step Into Liquid.
