I like what you did to it, but just like a lot of the modern extreme skiing videos, they used way too much slow motion. When I watch big mountain skiing and speeds sailing, I want to see it in full speed. That's the only way you can get a real feel for the speed they are actually carrying. Sure, it make the clips shorter, but slow motion just makes speed become boring. It felt like the intro to that thing, with the slow motion of the wave sailing was about 10x too long.
Having a speed event in the surf seems like a crazy idea. I can't imagin trying to go 35-40mph in surf, even smallish surf.
I started windsurfing back in the 80s and got into it a lot in 86 and 87 when full batton camber sails came out. It's surprising how little the technology seems to have changed in 20 years. I would imagine that the boards, sails and masts are bit lighter, since we didn't have carbon back then (I'm making the assumption that there is a lot of carbon in modern equipment), but other than that, the designs all look the same, and the speeds are about the same.
Thanks for the hit of speed!
