Carl:
I always believed that Cuben was a special fibre/cloth, and not something you could make from polyester. All literature I have seen on the subject, Cuben sails, speaks about Cuben fibre and carbon as far as i can remember.
Thanks for sharing that piece of information..

Now, do you know more about the exclusiveness of the agreement ? Is it the use of the mould, or is it the process of making Cuben from polyester that is exclusive ?

Hopefully, the ITA magazine "Fly Tornado" will give us the whole story in a while..
