With the 2022 series of the RS: Racing EVO we are introducing the high aspect ratio design that could already be found on the flight Evo. While the high aspect ratio is much more defined on the bigger sail sizes, it is less so defined on the smaller sizes. Thanks to this progressive high aspect ratio design, we are fully leveraging this design’s benefits. The sails become equally controllable on foil as well as on fin.

But what does high aspect mean for the sailor?
The high aspect ratio of the sail adds stability and helps to improve the stability of the sail, especially when foiling, this is important, as you don’t want any change in the position of the draft. As soon as the center of effort moves unpredictably, the stability of the flight gets interrupted.

HIGHER EFFICIENCY

Lift is created by the leading edge. On a high aspect sail, the leading edge is much longer relative to the sail size and this extra lift creates a more efficient sail for the rider. One of the major drag components is the tip vortex. On a high aspect ratio sail this is relatively less compared to the overall sail size, hence the effect is minimized. This allows the rider to reach a very stable high speed.
