I have worked on some of the organizing committees for some of the other class of racing sailboats (scows: E, MC and Xboat) and there is a difference between the beachcat guys and the others. Its alot more 'frat guy' with catamarans, in that the more simple the event, the better they like it. Kegs and Captain Morgan and BBQ vs. sit down dinners with wine. The boats are fundamentally different, so the wind is NEVER a factor with beachcating (as long as its blowing SOMETHING), the others are very particular. Like the beformentioned post about the lack of protests, in 5 years of racing pretty much every other weekend, I have only seen 1 protest, and it was a port tack resulting in a sunk boat.
So, in a nutshell, and I am speaking more for the 14,16,17 and 18 community, because I think the Tigers and 20 are a bit different than this as a general rule, I think the 'hobie way of life' is the laid back, adreniline junkie, no shaving, flip flop wearing, can of Old Mill drinking, sleep in a tent after sitting around a fire all night taking s###, being pissed you lost, but not too pissed,

kind of group. No offense to the tiggers and 20s, I just think the amount of money needed to have these boats is a bit different, therefore maybe attracting a bit more of an intense serious racing type person. Plus, you can't blast up and beach your boat, have it tip over on the beach and just laugh about it. If my new 20 tipped over on the beach, I'd CRY!!!! Care less if my 14 does. As long as nobody got hurt.
I hope that helps, its just my perception of what you're asking, and I am sure EVERYONE has a different interpretation.
