Ok, I know whats happened.
Kirby holds the rights, UKLA and assoc bodies around the world kicked up a stink about the reg/license fees Kirby charges stating that it was too expensive yadda yadda.. hence no new builds. Then it got messy and someone mentioned calling them a stupid name for the boat and all hells broken loose.
At HISC (my club) we are still calling them Lasers, still expect folks to abide by the International Rules around measurments (sails included) because those rules are still in place. If you want to sail with a non regulated sail you can but must make the choice of using that all season and let our Racing Committee know you are doing such.
I know Rooster offer sails, cheeper than the regulated sail and we have two folks (out of a fleet of 44) using these. The sails are better built, look better quality material (which has an effect on speed) and seem more durable. I feel we will go down the route of accepting these "type" of sails in all our Club Racing and Open Meetings UNLESS we get a protest from an interested body using Std Sails..
UKLA sanctioned events still abide by the Std Sail arrangement and setup of the boat.
I can't see this situation changing anytime soon until the point where there is a shortage of Std Sails and Boats, then they will come to a decision, as is it's temporary.
I'm buying a Laser too BTW, it'll be Std Sail, Std Build as I see the class reverting back to the original model base it was designed to be (and many regulations are already in place controlling the class)
Have fun, get wet, hike hard.
