Les mats platinum 2014 semblent tenir le coup (au moins une nav sans casser...)
à moins qu'ils utilisent des golds pour les vidéo :roll:

North Sails Warp F2014 detailed info!

Sails designed to win PWA slalom races the emphasis of the performance criteria is quite different in the different sizes.

For the WARP F2014 we went for a completely methodical 3-step process:
A. Define the criteria which are important for the different sizes
B. Analysis of each single size of the current WARP F2013 how it fits to the different requirements
C. Work on the weak points to design the ultimate WARP F2014

A. PERFORMANCE CRITERIA EMPHASIS
Everyone thinks on a World-Cup Slalom sail it’s all about top-speed no matter what size you use. But if you closely follow PWA Slalom races you will realize that when using large sizes in low/gusty winds it is ALL about a perfect start and acceleration after the jibes. The distance between the buoys is simply too short to win back what you’ve lost at the start or after the jibe by having a higher top-speed.
In 30/40 knots though that’s a different story: in these wind-speeds you need a much shorter distance to get into top-speed. Therefore top-speed and control are the major criteria for small sizes.
A.1. PERFORMANCE CRITERIA EMPHASIS FOR SMALL SIZES (UP TO 6.3):
1. Top-speed: 25%
2. Wind-range: 25%
3. Non-physical to sail: 20%
4. Low-end power + acceleration after start and jibes: 20%
5. Handling + rotation: 10%
A.2. PERFORMANCE CRITERIA EMPHASIS FOR LARGE SIZES (7.0 AND BIGGER):
1. Low-end power + acceleration after start and jibes: 40%
2. Wind-range: 20%
3. Non-physical to sail: 20%
4. Handling + rotation: 10%
5. Top-speed: 10%
As you can see there is quite a huge difference of what is most/least important for small or large World-Cup Slalom sails.

B. ANALYSIS HOW THE “OLD” WARP F2013 SIZES WERE FITTING
TO THESE REQUIREMENTS
1. Following the results of our analysis and comparison tests with competitor sails on the small sizes :
• Top-speed, wind-range and acceleration: our sails could easily compete with the best competitor sails.
• Non-physical to sail: due to the light-weight 7-batten-design the small WARP sails were also quite non-physical to sail.
• Handling + rotation: here our WARP is simply unmatched since years.
2. Following the results of our analysis and comparison tests with competitor sails on the large sizes:
• Top-speed: the current WARP F2013 was hard to beat – maybe even too much speed for how less important it is.
• Handling + rotation: here also the large WARP sizes were a class of its own
• Non-physical to sail: the 7-batten-design makes our WARP the lightest film Slalom sails on the circuit. On the other hand the large sizes were still a bit stiffer than the best competitor sails. NEED TO WORK ON
• Wind-range: once planing the large WARP F2013 sails were untouchable
• Low-end power + acceleration after start and jibes: this is where our current WARP F2013 was still behind compered to the best competitor sails out there. NEED TO WORK ON

C. WORK ON THE WEAK POINTS TO DESIGN THE ULTIMATE
WARP F2014
1. Small sizes (up to 6.3):
Our analysis and comparison tests with competitor sails showed that the small sizes of the WARP F2013 had already met the requirements nearly to 100%. Therefore Kai and his team kept the same design parameters and characteristics for the small WARP F2014 sizes and “just” tweaked the loose leech patterns to make these sizes even more performing.
2. Large sizes (7.0 and bigger):
After our analysis of the WARP F2013 the major performance criteria to work on was the low-end power and acceleration after start and jibes. Fortunately Kai and his team could take advantage of a design feature they had created when designing the E.TYPE, the most powerful No.Cam sail we have every made! By increasing the profile in the upper luff area the low-end power and acceleration dramatically improve as this extra profile increases the lift – cause lift is what ultimately gets you going/planing. We call this LUFF.LIFT.DESIGN
The disadvantage of increased top-lift though is a negative impact on the high-end control. This Kai could avoid through 2 design features:
1. Our PROGRESSIVE.LOOSE.LEECH design (in contrary to some competitor sails on our sails the looseness increases towards the top) helps to “release” power-peaks off the top (through a quite open/loose top)
2. The larger WARP F2014 sizes use shorter (= softer) masts than last year (see below). This increases the flexibility of the larger sizes making the extra lift/power easier to handle.
Another thing to improve was how physical the large sizes are to sail. The 7-battendesign makes our WARP the lightest film Slalom sails on the circuit. On the other hand the large sizes are still a bit stiffer than the best competitor sails.
To make the sails become more flexible Kai and his team decided to go for shorter (= softer) masts for the larger sizes. Now 7.0 and 7.8 are designed on the 460 mast whereas all bigger sizes (8.6 up to 9.6) go onto the 490.

KEY FEATURES
[NEW] [01] SIZESPECIFIC.DESIGN: each size is individually designed as small PWA Slalom sails have totally different requirements than the larger sizes.
[NEW] [02] LUFF.LIFT.DESIGN (7.0 and up): increased profile in the upper luff area increases the lift making for radically improved low-end power and acceleration.
[NEW] [03] PROGRESSIVE.LOOSE.LEECH: power-peaks can twist off the top as the looseness progressively increases towards the top.
[NEW] [04] Shorter/softer masts (7.8 and up): increases the flexibility of the larger sizes making the extra lift/power easier to handle. Plus makes these sizes less physical to sail.
ATTENTION: to ensure maximum performance we have reworked the curve of the PLATINUM 490 mast. Means sizes 8.6, 9.2 and 9.6 NEED to be combined with the new PLATINUM 490 mast! All other mast lengths remain unchanged.
[05] The 7.BATTEN.DESIGN makes it the lightest racing film sail on the market
[06] MODERATE.CUTAWAY.CLEW Reduced “blow-out”effect for increased power and direct acceleration
[07] INSTANT.ROTATION Much faster acceleration after shifting through HYPER.CAMS and modified batten profiles
[08] Continued weight reduction due to minimalized MINI.PROTECTOR and super light iROCKET batten tensioners
[09] INDEPENDENT.SHAPING.CONCEPT improves rotation, control and acceleration
[NEW] [10] 4.7 Speed: dedicated speed sail design for dead downwind courses, tested by Erik Beale.

STATEMENTS
Peter Slate:
“In developing the 2014 Warp, we were asked by our race team to focus on two areas: ease of use (less physical to sail) and acceleration.
We started out by altering the luff curve, and batten tapers of my 2013 Warp production sails. By reducing the luff curve at batten 3 and above, as well as, reducing the luff curve at batten 6 and below, we were able to make the middle of the sail, batten 4 and 5, relatively fuller. Internal testing showed promise, but it wasn't until we got to use the "adjusted" sails in the Maui Race Series, that we saw really good results. Most noticeable was the acceleration off the start line.
Having seen positive results, we went further in that direction. With the luff curve adjustments, we were able to reduce the overall downhaul tension required to make the sail twist. This, together with softening the batten tapers, made the sails much less physical, and easier to use. Early feedback from our race team is positive, and we are very happy with how the WARP F2014 came out.”

The 7.8, 9.2 and 9.6 have shorter lufflength to better fit a shorter mast. 460 on 7.8 and 490 on 9.2/9.6.
