NeilPryde Flight EVO11 Sail 2021
LIMITED AVAILABILITY - Please get in touch here to check stock.
For the foilers who want to push themselves to the absolute maximum around a course. The Flight EVO is designed specifically for racing, whether that's slalom or upwind/downwind racing. A new design for 2021 makes the sail lighter which improves stability and handling which is key for manoeuvres on the racecourse.
FOIL RACING. REDEFINED.
We are extremely excited to introduce the new Flight EVOII to the range. Experience foil racing like nothing before, thanks to the refined high aspect ratio of the sail.
The new 7-batten layout of the sail makes it lighter overall, and dramatically improves its handling especially during maneuvers, which is extremely important in foil racing.
We made it our mission to equip and design this sail to be the must-have for foil championships and racers that seek nothing more than their next victory. This sail is an evolution of its predecessor, fully delivering on the high aspect ratio needed to speed through your next finish line effortlessly. The Flight EVOII comes in race-ready construction and we have further optimized the balance of speed and control.
This sail has it all: speed, gracious design, stability and control, and it won’t let you down, no matter if upwind, downwind or reaching.
Quench your thirst for speed with the new Flight EVOII.
High Aspect Ratio Design
Foiling requires a very precise technique as it is crucial that the position of the draft stays unchanged to keep the flight stable and uninterrupted.
The very high aspect ratio design of the sail adds efficiency while keeping profile stability and this way dramatically improves the foiling experience. This specific design makes the sail’s luff longer, therefore allowing for the boom to be shorter, which translates to more control.
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.
Quadruple Luff Panel Layout
The Flight EVOII features four continuous, durable, stretch-resistant and lightweight luff panels that carry most of the sail body shaping. This configuration stabilizes the critical section draft position while providing an increased film thickness proportional to downhaul load distribution. Continuous panels eliminate horizontal seams crossing the highly loaded leading edge, which increases the response of the sail. Introducing this stable leading edge platform allows very high downhaul loads and integrated clear pocket construction.
Component Sleeve Construction
Combining different materials in the sleeve sections allows us to achieve optimum profile entry stability and elasticity, smooth rotation and light weight.
By removing any stitching that could come in contact with the mast we created a seamless leading edge. This increases precision during the assembly process, reducing weight at the leading edge and creating a perfectly clean profile entry to eliminate construction weak spots.
Lightweight TetoronTM Upper-front section (1) offers the necessary elasticity and durability to resist direct mast contact.
A low stretch DyneemaTM Armour Web section (2) can take high downhaul tension and is critical in stabilizing the profile entry, providing smooth bridging between UltraCams.
A tapered strip of TetoronTM along the back edge of the sleeve (3) where it connects to the sail body is used to provide the necessary elasticity in this area together with improved durability.
The bottom part of the sleeve is finished in our durable and elastic Luff Glide material (4) allowing for important smooth rotation.
Leading Edge Ridge
Carbon ribs sewn onto the upper sleeve’s leading edge stabilize this critical section of the profile on the highest battens where cambers are not used.
This helps maintain the sail’s profile clean, reducing drag, allowing higher top speed and ensuring proper rotation.
