Carbon is LEGAL, and I think if you wanted to, you could build the whole boat out of carbon if you'd like. At least, I think.

At the moment carbon is legal. There was a proposal to ban it in the class with the reason being to try and keep costs in control.
I think the way the rules are currently written it does not matter. A min tip weight on the mast, min weight of the platform and non-glued beams pretty much makes the use of carbon a non-issue. The potential performance difference is limited with these rules and the cost to go with carbon is significant. If some one want to have bling they can, but IMO with these limits it still will not win you any races.
