The cylinder is at the heart of SHADEONE®
The unrolling of the sail and the necessary tension are combined in a simple way. When the sail is unrolled from the cylinder, the tension cables are rolled up through the rotation of the tapers. The tension cables and sail stay under tension in every position. Operation is simple: the SHADEONE® Twister-Sail unrolls by itself within seconds, and rolls up just as quickly and easily by way of a pull cord which is then simple to tether.
