I have no experience on a N20. But sitting on the beach they are a very good looking boat. This is my 2nd season racing a H16 and the Nacra seems too technical, and too reliant on having really good crew for me, (which I never have consistently). The one design racing for Nacra's in the upper midwest isn't as convient for me either. I've only done a couple of Portsmouth reggata's on my 16 and didn't care for it. Mostly because there were a few spin boats that were borderline terrifying when they'd come tearing by you downwind. And starts, I had a couple of brilliant starts only having to make room 20 sec.s after the gun for the boats that point much higher. Whether this is heresy or not, I have no clue, but I've heard it takes a couple of hours setup time on the bigger spin boats as well. I don't like the half hour it takes to launch a 16. But I still really want to experience a N20 sometime.
