I seriously doubt there is a 1k of them out there, more like 400. Sail numbers are in the mid 500's I believe and they probably started production boats at 100, but I don't know that and I'm just taking a stab at where they started.

I'd bet there's 100 in the US, but nobody races them. I can think of about 9-10 boats that I know of. A dealer in Cali said he sold a dozen last year, but once again to nobody who races.
