While continuing to wish the Zim team all the best for their new boat, and realising this continues the hijack of the thread, a few things stick out from the comments above.
While I have sympathy for mustang being so far from good sailing water, there are more than enough Americans that live close enough to the coast for this not to be the reason why dinghy sailing isn't strong in the USA. And here in Oz, most dinghy clubs launch off beaches and don't need any flash facilities. Again, that is an excuse, not the problem
One thing i hadn't considered until reading above is the whole issue of cost. One of the posts above says there is good sailing, with a fleet of 505's, A's and F18's. In most countries, those would be considered very expensive, top end boats. You cannot build the sport based on boats like that. Back in the early 1990's a revolution started in the UK with builders like Topper, Laser and later RS bringing out boats that sold in large numbers. The common feature of all of these boats was they significantly undercut the price of the equivalent boats in existing classes without a loss of performance. By way of example, take a boat that sold in large quantities despite a lot of people now saying it wasn't great, the Iso, which was probably the first of these new wave boats. It was faster than a Fireball, about the same speed as the 505 was then (pre big kite) and it cost about half the cost of a new Fireball and about 1/3rd the rpice of a new 505. In fact, you could buy an Iso for less than any competitive s/h 505, Fireball etc. We saw the same thing a year later with the Laser 4000. Since then, RS did exactly the same thing with their boats. The RS400 cost a fraction of what a Merlin Rocket cost, the RS800 is far cheaper than a 49er or I14 and far easier to sail.
IMO, if you want any chance of growing dinghy sailing in the USA, you need to get the price point of the products right and based on what i read here and elsewhere, i am not sure I see evidence of that happening.
+1 and for Australia too.
Possibly need to get rid of those "Blazer wearers" that seem to hang around on the committees of a number of clubs too.
