Okay so the NA rig is the same as the Texel N6,0 SE (Special edition ?) The numbers match. <br> <br>Under texel 2002 this NA N6.0 with spi is rated at 95 while the EU iF20 is rated at 96. Seems to be an acceptable performance difference. 1 % is not that much on the race course. And ofcourse a smaller jib can rated the N6.0 back to 96. Under texel the NA was measured with a 5.5 sq. mtr., jib <br> <br>Thanks for the correction though. <br> <br>Carl, for you (because I know you understand rated sailarea) The rated main sailarea for the NA rig is 17,09 sq.mtr. (iF20 = 16 sq. mtr) So the 19,43 actual area with respect to 18 of iF20 which has 9 % more area is decrease to 7 % effective area due to the fact that both rigs have about the same lufflengths and mast height. I'm sure however that in light air the squaretop of the iF20 class provides about as much sailpower as the pinhead of a N6.0 <br> <br>Wouter <br> <br>Wouter <br> <br> <br> <br><br><br>
