North Sails presenta oggi ufficialmente le nuove Warp 2013: le vele che accompagneranno gli atleti North Sails nelle tappe PWA slalom (programma slalom race).
Le caratteristiche: maggiore accelerazione nelle metrature piu’ grosse, maggiore stabilita’ nelle metrature piu’ piccole.
Kai Hopf e Peter Slate promettono delle vele piu’ morbide.
Sails designed to win PWA slalom races have different requirements in the different
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.
[NEW]  SIZESPECIFIC.FLEXIBILITY Individually adjusted flexibility for each size to
perfectly match the conditions and different rider weights.
 PRONOUNCED.PROFILE.DEPTH for advanced camber-rotation, deeper profile and
more punch when accelerating, without compromising the handling
 Radical weight reduction thanks to the 7.BATTEN.DESIGN makes it the lightest
racing film sail on the market
 MODERATE.CUTAWAY.CLEW Reduced “blow-out”effect for increased power and
 INSTANT.ROTATION Much faster acceleration after shifting through HYPER.CAMS
and modified batten profiles
 Continued weight reduction due to minimalized MINI.PROTECTOR and super light
iROCKET batten tensioners
 INDEPENDENT.SHAPING.CONCEPT improves rotation, control and acceleration
 TWIN.TRIM.CLEW allows for individual tuning increasing the range of use
Size 5.2 5.7 6.3 7.0 7.8 8.6 9.2 9.6
“Across the board the sails have become softer.
Biggest changes are in 8.6 and bigger with the addition of 9.2.
The 9.2 was introduced as some of the team felt for their weight last years’ 9.4 was too
By the time racing occurs with PWA wind minimums they were already overpowered.
Goal with 8.6 and bigger was to drastically reduce the amount of force it would take to
inflate the sails.
This helps to improve the out-of-jibe performance and getting planing both static and
I believe we found the right compromise as going too soft makes the draft / center-ofeffort
Key to performance sailing is being able to trim your equipment to the optimum
position, having a rig where the center of effort is constantly shifting makes this task
What we have achieved on 8.6 and bigger is that you can pump yourself on the plane in
less wind then you can actually keep planing.
The smaller sails get more emphasis on the center of effort being completely locked in
making it even easier to find that optimum trim and holding it to continuously increase
“When developing the Warp F2013, we focused on improving the perimeter tension in
the smaller sizes (7.8m and down) and softening the bigger sizes (8.6m and up).
In the smaller sizes, we achieved the our goal by reducing the luff curve in the top third
of the sail, which improved the twist and keeps the fullness focused in the middle and
bottom of the sail.
In the bigger sails, we reduced the overall luff curve, and increased the negative
shaping to double down on softening the sail.
Testing against our 2012 Warps and other competitor brands, we are very happy with
the softness and increased ability to pump the bigger sails. The reduced luff curve and
new shaping allows for a very stable sail that is fast and light in the hands.
We are very happy with the Warp F2013, and are confident you will be too.”
