Sail 6000

have you had a look at the european iF20 rules?
Hobie. Nacra and Swell all built boats to this rule that competed well. It looked like the class was going to take off with guys that were too heavey for F18. Unfortunately, there was only space for one formula in europe and iF20 did not get going.
Nacra europe are now marketing the inter 20 as a one design which appears to be reviving interest.
