It's rating at 59.3(provisional) and as we get data we will continue to update. The sails are 50sqm you can divide them up per the rules but the latest sails are following the development lines of the F18s since that is where the biggest changes have been in the last 10 years. I'm aware of 3 sailmakers building newer design sails. Schurr, Glaser and Performance.
The F20na fits in the class. Hopefully we'll get a chance to see how she performs.
There have been a few mods to existing N20s, different mast/booms/spin poles and most notably the sails.
So what I am reading and using the Inter/NACRA 20 as an example is that you can go from 45.15 meters square to 50 meters square of sail area; about a 10% increase, and still maintain the orginal N20 59.3 DP-N rating, albeit it being provisional?
