Along the same lines, I have always been under the impressing that wing masts cost way more than regular masts. I was thinking about it and was wondering if they could be constructed from the "normal" carbon fiber masts but adding a carved foam leading edge and a couple of flat panels on the trailing edge. The wing shape must not have to be that strong, since there are soft wing sails. The strength could be provided by the filament would round mast and the rest by relatively weak shaping. Oh, and I am talking about the partial wing, with a sail, not a full wing. Comments?
