agreed. therefore let's experiment with today's materials and come up with a sail that lasts!
Noting is stopping anyone from coming up with a wonderful Laser sail and marketing that sail.
There is a copy right owner who will not allow anyone else to use the Laser name with respect to sailboats.
If you want to develop and market a better sail, go for it.
If the class association decides your design is better for teh game of Laser racing than the sail supplied by the builders, the class association can decide to allow its use in Laser regatas.
If the builders decide it would be more profitable in the long term to supply boats with sails designed and sold by you, they will purchase sails from you and supply those sails with the new boats.
Make certain you not only take the time to design your sail but also make certain you copy right the coincept behind the sail for the Laser which is like yours and not like the ones currently defined and supplied by the builders and class.
I wonder if a person could copy right "all the designs other than" the legal laser sail design???
