The early windsurfer rig 'pull up' lines were stretchy polyester and I found them comfortable and easy to use. Although I do recall that once the sail overcame the 'stiction' it came out of the water pretty quick. By contrast, when on holiday last year in Greece, the uphauls on the boards available were all prestretch. I know I'm getting older, but I had a hell of a time trying to pull up a 6.0m sail!!

Your post, Wayne, has just given me a 'eureka' moment - now I think I know why it was so difficult compared to what I remember <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />
