You are correct, the main is not radical and Richard Roake came back and corrected that point one 2 or 3 of these threads a few weeks ago, so drop it, it is already dead and beaten over the head a long time ago. As to the wing, for what it is, it does fall under the radical design aspect of this conversation. It is a take off of what the C-Class has featured for years, but it also is a wing designed for how an A handles and sails. The simple fact that you have enough drive to do this and take it to the worlds as your first major regatta is a big and some would say radical step.
