The Blade has defined the 5-batten wave sail category for nearly two decades. With the new GRADIENT PANEL TECHNOLOGY improvements are obvious. Lighter weight and better stability. Corners have overlapped panels which reduces the amount of patching. At the same time, these overlapped areas extend into the body of the sail so it transitions the load much better, will be less stretched over time. It’s a more stable way of building sails. Rather than a single curved luff panel, the Blade uses separate panels that radiate out of the head and tack corners. This perfectly aligns the sail material with the direction of load. Previously the curved panel would have bias stretch in all the wrong places. Direct transmission of power. Increased longevity. Total Control.
