I don't know how I missed this but several years ago, sailing coach Dan Brandt at Richmond Yacht Club introduced a Laser with an Opti rig. I would imagine Richmond Yacht Club, being just off to one side of the very windy and choppy Berkeley Circle on San Francisco Bay, would find a very depowered Laser of great use for their junior sailors. Come to think of it, at this time in my life, this is just my speed for racing a Laser in anything over twenty knots.
More info on the L'Opti can be found here.
Also, at about the same time the L'Opti came out (2011) there was, that year, another performance rig introduced for a Laser.
