The new S-1 Pro is the premium version of the 4 batten S-1.
These CarbonFusion sails are the only production windsurf sails using carbon fibre laminates from head to tack. Carbon is a higher performance fibre than the Technora, Kevlar or polyester used in all other sails. Better strength to weight ratios, more reactive, wider wind ranges.
This production technique is highly accurate, reliable, and consistent. There are no differences in finished sail weights.
The GRADIENT PANEL TECHNOLOGY logically reduces weight, increases strength and controls stretch. Overall weight is reduced but the more significant improvement is the feel – quicker reacting and lighter feel.
Rather than a single curved luff panel, the S-1 Pro 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.
The boom length has been shortened on bigger sizes (4.8 and up) to reduce the back-hand pressure that builds up as the wind increases. Instead, the power has been shifted up in the sail giving more leverage to accelerate instantly in light winds.
