Hi Jamie,
No, I did not look up the link. In the world of aerodynamics, starting with areo 101, the % chord of an airfoil is defined as the thickness to chord ratio times 100%. Wing masts were tried and passed over about ten years ago. To be effective, they are large. When they are large, relative to normal catamaran mast, they are very stiff because of their moments of inertia and heavy because of their large surface area. Being stiff, the mast plus sail is set at one camber. There is no flexability in sail shape/control.
I built a wing mast once. I built a plug and then I built a mold. Then I built two masts. The mast section was 12 inches long on the chord and 5 inches max thickness and 45 ft tall. I spent one winter doing this project. I have never worked so hard for no improvement in my life.
