Sails designed to win PWA slalom races have different requirements in the different sizes:
1. Large sizes need to inflate very easily so that when you sheet in or pump the sails the power comes on instantly for immediate acceleration.
2. The smaller the sail the more focus is set on having the draft locked in (both horizontally and vertically) and the sail not moving around excessively.
Usually sail designers tend to use the same design parameters (twist pattern, aspect-ratio, sail foil tension) across the whole sail line. This results in some sizes being much more competitive than others.
For example our last years’ 7.8 was perceived as the most competitive on the circuit. On the WARP F2013 Kai went one step further. He and his team checked the best sizes of all competitor sails and then went into individually adjusting the flexibility of each and every size. This we call SIZESPECIFIC.FLEXIBILITY.
In general you can say that the smaller sizes (up to 6.3) have a lower flexibility. This allows for the board and rig to be placed in the optimum trim for top-end speed (locked-in characteristic). You just keep on getting faster and faster the harder you sheet in and the stronger the wind gets.
On the other hand the larger sizes have a higher flexibility. This improves the low-end acceleration as the deep profile pulls you onto a plane while the reactive top reacts as a “valve”. This higher flexibility also makes these sails much easier to pump. The outcome is simply amazing. The smaller sizes are even faster now.
The biggest improvements though were made on the larger sizes. The 8.6 is the most competitive sail we’ve ever made in this size.
It is much more flexible which makes it easier to accelerate and pump, yet the high-end control and v-max is on the same level than last years’ model.
The 9.4 got replaced by a 9.2 and a 9.6. This enabled Kai to individually design this biggest size of your quiver to the rider weights: riders below 90kg should take the 9.2 as their biggest sail as it still has an even better acceleration and low-end power than last years’ 9.4.
The new 9.6 is designed for heavy and powerful riders above 90kg. It is the most powerful slalom sail we’ve ever built.
