I was just pointing out that the ones involved are the kind of people who know every detail of their boat. It has nothing to do with the one design mentality. I understand that custom sails are available and own a nice set of Custom sails. However when I ordered them I made sure the sails would measure to be class legal and only use aproved materials from the F-18 class rules.

So if there is no performance advantage why would you use an unaproved material? When you base your name on your new boat and new sails then show up at the worlds with something thats illegal. It makes no sence.
