RE: Stop Formula XXL Sails!
FW does push the boundaries of WS in a particular direction--it's an extreme part of an extreme sport. And not everyone needs do do it. But the joys of fast upwind/downwind sailing are there. , and they're unique.
Just as modern freestyle pushes the sport in a different way--I don't even know what some of that stuff those guys are doing is, but I like that they do it, just the same.
