Not sure how this thread went into the planing and longboard thing, but fact is. Yes planing is fun to do and super-easy to achieve on modern gear, gliding about, long reaches and all that. No, it's not a crowd pleaser, since everyone does it at the local beach. It's not for bystanders, it's not even a crowd pleaser amongst windsurfers !!
Nobody will line up the shores at the Olympics to watch racing just because it has early planing fancy boards flavour-of-the-month. ("Serenity now" - Seinfeld show)
The goal of the Olympics and ISAF is probably not uniquely to please recreational windsurfers per se, though it's only my opinion and I could be wrong on that.
