Our anti-wrinkle treatment
Double 3D Shaping could be called an anti-wrinkle treatment for the nose of the wing: with two seams across the entire span of the top sail, we reduce the number of creases which are a consequence of the curvature over two axes. Two axes, because the sail cloth has to align to the profile form and the ballooning also determines a radius which the cloth also has to follow.
It is as if trying to fold a piece of paper smoothly around a ball. Impossible without a few wrinkles.
Double 3D Shaping divides the sections to be folded into smaller subsections. This allows us to get close to achieving the ideal crease-free form. The result of Double 3D Shaping: the creases on the profile nose are clearly reduced and this leads to better performance.
