20 was and still is a great boat but the writing was on the wall 3-4 years ago when 20+ F18's showed up at major regattas and on a good day 6 N20's participated. F18's have class-controlled open sails, meaning continual sail development, at the same or cheaper prices than the N20 "one-design" sails (which never measured the same twice and no measuring guide was published for the class).

I wanted a larger fleet experience with opportunities for large Nationals and potential for World's, combined with the ability to distance race on occasion. Good thing is most of those N20 parts are the same as the F18 Infusion parts so you should be OK!
