On another thread there is talk of how a sail's luff may not be right for the mast.

I am interested in what to look for, what to measure, what to keep in mind when i am at Robbie's or some one else's yard/sail sale.

I recently shredded one of my used Tornado sails (808) that seemed (to me at least) to be perfect. I have another T sail that handles heavy air well. but is no where near as sensitive/responsive as the 808 sail,

I couldn't tell you how well its luff cut, fits my mast shape.

I may try to repair the old sail, but really need to look for a replacement for the light wind of the summer

Thanks,
