Yeah, and the "experimental class" thing was why I never really understood why they banned the tunnel hulls. It's too bad in a way, because in some conditions they might have been competitive with the unstable skiffs that dominated until the foils came along.

I'm in Australia, and we just sail off the beach, and the Scow shape was perfect for that.

There's an excellent discussion of the design at [1]. I have to say I'd love to try out a foiling Moth one day though.
