The gaff angle look really extreme. I would have gone for a more conventional and tested gaff angle.

I would have shortened the leech a bit. As the sail is now it looks like you will be sheeting the main block to block. How will you get under the boom when tacking/jibing?

Have you checked how your mast bends and adjusted the luff accordingly? The luff curve looks very conventional for a comptip. I would have expected max luff round to be higher?

13deg twist.. Looking forward to hear how that works out for you! It is at least enough..


The Tornado have no vang, just downhaul, outhaul and mainsheet. Would be cool if cut a suit out of sailcloth. If North can sell clothes, why not. <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />
