thanks for your responds.
 Kicker ist may an issue. In very light conditions (F1) I need really a lot of kicker tension to flat out the diagonal wrinkles. I end up usually with too little twist - may be this is a general property of all unstayed rigs.
In more wind (F2 .. F4) I feel very comfortable whit the trimming - I can give all shapes into the sail. So far, I still hat o lot of free way at the cunni. But I never had more than a single F5 puff - so I have no experience how to trim in windy conditions.
Question: Is there any "trim tables" available for the aero?  How do you trim your sail in light, medium and high wind for up- and downwind?
 
@ Sandy: I'm on Thunersee in Switzerland.

I wonder how much kicker you have applied. When first hoisted the luff of my sail is not even below the track and I have to be careful it doesn't catch as I first apply downhaul. However as soon as I apply some kicker to put a bit of mast bend on the luff easily comes down, and when it is windy I apply a lot of kicker and downhaul upwind to de-power. It needs all the range then.

Hi Röfe,
 
I don't think you're doing anything wrong, nor is your sail too short, or any shorter than all the others. The sails of this type are cut usually a bit short of max on the luff in order to ensure that you don't run out of room to stretch the luff downwards, regardless of whether you have the sail hoisted all the way to the top or not.
 
Generally, upwind, the luff is tensioned very little in light airs. Horizontal wrinkles can help to distribute the luff curve that is built into the sail to accommodate the greater mast bend that will occur in higher winds. Then gradually more luff tension as the wind comes up....just enough to remove horizontal wrinkles. Then in heavy air if you are feeling overpowered, you will find you want "lots" of luff tension. A fold or crease parallel with the luff will indicate too much luff tension.
 
Which lake are you on? 
 
Happy sailing!

dear all,
 as a first-aero-in-the-lake-sailer i may come up with an odd question: when I set my sail (9er), the cunningham eye is located well above the boom. Even if I bring on the cunni, I never come into the range where the scale on the mast indicates some trim-marks. Also compared with the picts on youtube and so on, it seems that my luff is some 12cm too short? It is possible that the sail will expand while using it, meaning all brand new sails show this effect or I am doing something wrong?
 
What is the "commen strategy" for bringing on the cunni? I stop before producing any crinkels along the mast.
 
The hailyard is set "as high as possible". There I do not see any options.
 
Thanks
Röfe
