>> howevere i'm not too sure how the sail area reduces with mast length using the formula for rated sail area
<br>
<br>Ohh, that is simple the formula is such that the benefit that you get from a longer luff mainsail is corrected by making the maximum allowed mainsail sailarea smaller.
<br>
<br>Go to the Texel rating calculator and ply with the number s of luff length and mainsail area. Try to keep the rated mainsail area equal or less than 13 sq. mtr. you'll see what i mean.\

<br>The rated sailarea formula is fix in its outcome and it has only two basic parameters which are linked together to create that fixed outcome. So if one increases the other must descrease.
<br>
<br>Okay, John what would you consider a good limit in mast height ?
