Well if you want to pay a highly priced sail, it will always be an option for you.
frankly the sails are not cheap for what they are, obviously, the non-class sails providing a plain demonstration.
If a non-class sail sells for around US$100 retail, imported in the US, it's a reasonable guess that the production cost should not exceed US$50 - as there is transportation, and obviously retail margins involved.
the buttons could stay, or go.
What is needed is to have several approved sailmakers, competing with each other, and producing exactly the same class approved sails
The fake sails would progressively disappear probably. Rooster, Intensity, and others may prefer to make class legal sails if they are welcome by the class to produce them.
The only thing that the class really needs is the removal of the regional sales limitations, and that really seems to be coming now with LP out of the game. I agree that having a choice of several suppliers is a good thing, not primarily for the competition between them, but to have a steady and reliable global supply of equipment.
