Oops....Sorry....if I read a little closer, I think I figured it out....if I read correctly...."AS LONG AS" I keep "stock" EP sails, I am allowed the larger NE Spin, vs. being limited to a 300 sq ft spin.
It just seems a bit strange to me as a stock 6.0na weighs in at 420 lbs, and has the class max sail for both Main and jib. As such I am curious why I would be allowed a larger spinaker...is it because the mast is a tad shorter than an I20 for example? I guess I shouldn't complain...just take it as a blessing and run (sail!!) with it!!
