$11k for an Inter 20 rig? Wow.

I'm investigating finding a suitable carbon rig platform to replace the alum Hobie Tiger rig used on an Open570 sportboat monohull (28' rig). I looked at the Tornado Rig and it seems suitable, @3200 Euro but shipping is difficult. Could anyone recommend what class of cat has a readily available (in the US) carbon rig between 28' and 32' high?

Do you think the move from aluminum to carbon is a big deal on boats this size.
