It would be the builders (who also determine the price you and I pay for sails and all the other class approved stuff)
You determine what you pay for stuff.
If you don't like the giving price the money to the seller, you don't buy.
Every single one of you who has bought a Laser or parts or sails for your Laser made a personal decision that the price was fair.
Further. KNow this.
If generic sails were 100% legalized for racing, the same people who buy Benydryl, Advil, Claritin, Bayer, Neosporin, Coke, Kelloggs Corn Flakes, Comet Cleanser, GE Silicone, Interlux 216 thinner, Budweiser water, and other Brand Name products, would still buy oficial Laser Builder supplied sails.
