Carbon mast, foils, ruddersystem and careful selection of sails and blocks.. 23kgs is the target weight I think and if the hulls are 6kgs overweight in total that is no big deal. I would be happy to sail with a platform 6kgs overweight. Let me know if you want to get rid of those hulls and I'll be happy to discuss solutions with you.

Sorry for hijacking the thread, I'll go away now.
