Sorry for asking. Have my boat miles away and need to order new mainsheet. What length are you using (I remember it to be 13.5 meter? but it sounds lengthy) provided you use it back-to-back. Also, am I right in assuming tapering would be arround 3 meters to be able to lock it upwind in full swing and outside tapered area (using normal mast rake).

Cheers,
Jonas

hope this helps
