Hi I am looking at purchasing a late 80's Nacra 5.7. Just wondering on how this boat is for fun-sailing and occasionally racing. I have 15+ years of sailing experience(Laser, Melges 24, Melges 30, Swan 57, etc. etc.) but not a lot of catamaran experience besides taking out the occasional Prindle 18 locally. I live in San Diego (half a block from Mission Bay). Thanks for any help you can provide!!!
