A while ago I wrote about my past experiences with sail stripes. It seems like sail stripes are getting more and more inventive these days. From Alinghi's new windsurfer-like main with red stripes and contrasting white stripes which I assume are still designed to aid in digitizing the sail shape:
to a boat called Onyx from Switzerland, which is sponsored by a printing company that specializes in extra large printing.
Very different usage of stripes!
