Not actually an anarchist.
Very contestable. The RS400 came out many years before the 59er, indeed it was the first RS boat. Its not really a skiff type at all, being basically a sanitised mass market version of a Merlin-Rocket.... confirmed when RS launched their own version of the concept - the RS400 - which I understand, being more production and polyester resin built, out competed the 59er on price. But all of this is second hand knowledge, so entirely consestable..
I don't think it had any significant sales anywhere. I have a number of theories why it failed, but I think people putting wires on it unofficially was certainly part of it, because who needs uncertainty about what the boat is for. Why would you buy a boat for two heavier sailors if it looks as if its going to get a wire and thus be faster with a lighter crew?
