I have the opportunity to pick up a Nacra 5.5 on the cheap. As I know little about these catamarans I was wondering if anyone could enlighten me on this boat. I think the one I am looking at is an SL (Sloop) as it has jib and screatcher/spin? Do people still race these? Can I still get parts, sails, etc? Anything to look for in particular?

Thanks in advance.
