The surplus of the Nacra 6.0 sailarea is completely caused by the large jib. According to Texel the mainsail is
<br>
<br>17,46 sq. mtr. which is 18- 17,46 = 0,54 sq.mtr. smaller than allowed under iF20 rules
<br>
<br>It's jib is 6,23 and much larger than the 4,85 allowed under iF20. However, you probably lose the excess anyway when you want to sheet the jib from the forebeam or make the jib selftacking.
<br>
<br>What surprises me too, is that everybody claims that the I-20 needs the extra sailarea in (Lighter ?) US conditions, but the Nacra 6.0 has less mainsail area than the iF20 and nobody claims that this boat is under powered for US conditions.
<br>
<br>On the contrary , N6.0 is by many still considered the best boat on the US market.
<br>
<br> Will you be punished hard for reducing the jib area ? Well, not in costs that for sure and when you add a genaker than the negative effect of downsizing will be more than corrected by the addition of a genaker.
<br>
<br>So this modified N6.0 will get a performance boost under the original iF20 rules.
<br>
<br>One side note. In the US the nacra's sail with a slap under the lower sailbatten. This one is often removed in the EU for it is counted in the total sailarea and measured lufflength but it hardly contributes to the produced sailpower. Read Frank Bethwaites book on why this is, you can trust me on this one. So I say just dispensate this flap on the N6.0. Besides the N6.0 is also a little heavier than the min iF20 weigh, so it is not that it gets an unfair advantage of any sort.
