I have a 2001 6.0na, and I like the boat. It sails well, very fast, and extremely good in heavy seas. However, the tramp layout is very small. The boat was not designed for a spinnaker, and so very often the lines get tangled when flying a spin. And the oversized jib means that the jib blocks and sheet are on the tramp. I am moving to a Nacra20 (was Inter 20) because it will be much easier for spin handling. I am also told that the N20 is a bit easier boat to sail well. In terms of handling, I really like the 6.0. It tacks very well, handles well, a real joy to sail. Lots of freeboard which is nice. You could pick up a used 6.0 for a lot less money than a N20, so it depends on your budget. But if money is not a problem, then I suggest the N20 because there are more out there racing now, and its the current boat. Get a freshwater boat if you can.
