This is similar to the start of the Wave Class of Hobie. We started the Intl Wave Class Assn, and made our own rules. You can buy sails and tramps that are very good quality and lower prices. Competition is the reason. Everything has to measasure in. Good part is you can have your sail cut flat (if you are light, sail in flat water and/or big air), or full (if you are heavy, sail in big seas and/or light air). Just take a look at our rules and constitution at www.waveclass.com and use that as a template.
