Good luck "screwing the opti", biggest junior fleet in the world, one of the biggest OD in the world, all the top worlds sailors started in them. They may not be the sexiest things out there (or at all), but I wouldn't try to replace the Opti, I would simply work with it.

besides, its hard to argue that kids who learn how to drive an in an opti don't know how to drive anything else... I digress.... beauty of sailing, you can find a boat / role for almost all personality and fitness / physical types, the key is finding it early enough that you don't leave the sport.

Now, back to Multihulls in the Olympics....
