Thanks, Slieve, for chiming in. I appreciate this.
1. You are right - the main luffs sit right behind the mast edge (aft), not on the mast (or the centreline). This will be an easy fix.
2. The lower mast diameter is 120mm and the split is 200mm. I would think this is enough, or is it?
3. This is potentially true. However, the hinges on this sail are so "tight", that there is probably very little air going through. Probably.
4. The camber on the jibs has been done along your instructions (was it something like 15% or...?). I have also re-measured this from the sail (by measuring the lens, not the actual formed camber) and checked that it's ok.
5. I have tried different sheeting arrangements and traveler-like systems to be able to sheet in as much as possible. I haven't noticed a drastic effect to the pointing ability.
6. Some of this is easy to swallow, some of it not so much. We have to remember, that I have sailed this same hull with a (tired) BR, a Hasler-Arne -type JR and a SJR (oh, how good a laboratory my boat would've been if I just were more engineering-oriented). I strongly feel that the ability to fly through chop has severely been affected by lack of drive towards the wind.
7. The whole chord length is 4000mm, of which the main takes 3000, the split 200 and the jibs 800mm. As you can see, the balance is less than instructed. One of the possible solutions for our situation would possibly be lengthening the battens 150-200mm and sewing now jibs (as I said on an earlier post).
