I would like to bring my 2 cents worth to this debate, I know we are across the pond but some points that you should consider are:
1.) The class will benifit by association with this event which looks like it will be quite high profile and well run.
2.) The logistics are already in place, and whilst I'm sure the other options could also produce a good regatta, it will need a lot of work in a fairly short period of time to match Ricks offer.
3.) How many people would actually attend if the event is at Ricks, we intend to go if it is at Ricks.
Even if only four or five attend, it will be a good showcase for the boats.
