: Who's the designer?

Mladen Milidragovic from Vancouver, BC, Canada.

http://www.wingsails.com/index.htm - Mladen's original wingsail website is much changed,
but still includes pictures of his soft ( inflatable bladder ) shape shifting wingsail and a kayak sailing video.

I have 2 dacron wingsails (26sq ft each) based on his design and made with his permission.

The bladders are inflatable pool noodles as I recall. I made 2 take apart aluminum masts for a guy in Cleveland
to use on his two masted ACA racing canoe, and he made me the wingsails. I lost interest before completing my
folding sailing kayak with amas, and never tried the wingsails.

My interest is once again peaked. Since I already have the wingsails, I'm going to give this conceot a try on my new woodstrip Sea Bee.
That's assuming I can find the box where I packed away the sails several years ago :)
