Yes, I would like too see a maximum luff length. Maybe it is smart to ask what the sailmakers think is an optimal shape genaker and calculate back the luff length when the total genaker area is 17 (?) sq.mtr.
<br>
<br>Another option. Specify where on the mast the genaker luff may come. And fixing this point via load calculation. This as an answer to Kirt -failure- remark.
<br>
<br>If these are to complicated I'll say 17 sq.mtr. max size and a maximum luff length that puts the genaker halveway between the masthead and hounds. This will limit loads and allow some freedom to experiment.
<br>
<br>Later on we can maybe use an aspect (efficiency) formula a la Texel like Wouter proposed for the mainsail area.
