This format exists across the US and is hosted by many weekend regattas already.
If you're asking if I would attend a DPN/SCHRS championship with a $50 a head upcharge instead of my fleets national championship the answer is no. However, if the event was SCHRS and I had access to a Viper (104) and the event was in my backyard I'd consider it.

I think everyone would agree that sailors primary focus will be their OD NAs.
So.. Would you attend a second "national" championship (3-4 days over a weekend) in your OD class.
The concern is that the Host of the NA's will get pissed at another national event sucking off sailors who opt for the closer drive of the two regattas.(The answer could really depend on the OD class you are talking about as well)
PS... for 2012... the option is One Design on F16's... charters should be available.
