You're right, they're having fun, they're one-design. No gimmick, no Tupperware party. This is the nearest thing I've seen to the original days, which most sailors have never known. They do "freestyle", move about, try things, fall, etc.
That's the only way. People who bore with the sport are those not doing that, going right and left for 1km reaches, and buying fancy equipment too to do that.
