i hadn't thought about contacting the manufacturer, but this is for a used, modified, tornado sail for a mystere rig. i would wait to bring it to a local sail-maker and have him charge me to mend the sail at this time. But good idea, and i will keep it in the back of my mind if i need to keep searching. Thanks

I am very (more) interested in hearing the opinions of the very knowledgeable people on the forum about the theory of the pre-bend/spin relation, in safekeeping my mast in 1 piece.
