So for argument's sake, suppose a new sail design is ready to go and presented to the class today. How long until it would be sold? I figure two years - a year for the membership to vote, and a year to actually get it in production.
I'm probably going to need a new sail soon. I expect it would be worn to a bloody pulp long before any new design is available.
One thing I just read in the June Sailing World is the Tornado class is moving to "one-design sails", which I take to mean sole-sourcing from a single sailmaker. It's an effort to cut costs (just threw up in my mouth a little) and get back to Olympic class status (and the Olympics badly need a catamaran event IMHO). I think one difference here is the one-design sails are controlledl by the class, not the manufacturer.
