The price Rich is quoting is for the Exploder Tornado, and is being used as a selling point to get the class back into the Olympics. The price is quoted here: http://catsailingnews.blogspot.com/2012/02/olympic-trials-interview-with-roland.html The boat comes with one-design sails, which are also price controlled, so I'm sure that helps.
I suspect that part of the reason the price is relatively low for the Tornado is supply and demand. How many Tornados have been sold in the last few years? Have any of the Exploders actually sold at the price given, or is it part of the campaign for the games?
I don't know the answers, and I'm not accusing the Tornado class of anything, but I'm not sure it's a great comparison.
