Twist Shaping Concept

Sail twist allows even more release than EVO9, so you feel like you have gained an extra gear. Even with just seven battens, EVOX opens instantly, gaining that moment of acceleration when going through a gust, feeling much more stable and preventing the center of effort from moving back in the sail. The result is reduced backhand pressure that gives smooth acceleration boosts in gusts.

Progressive Aspect Ratio

Provides a specific functionality across different sail sizes. Higher aspect ratio in larger sizes (7.8 and up) reduces boom length, delivering light wind efficiency and improving maneuverability. Lower aspect ratio in smaller sizes (7.0 and down) keeps a longer boom helping to maintain top-end control and stability.

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. Lightweight Tetoron™upper-front section(1) offers the necessary elasticity and durability to resist direct mast contact. A low stretch Dyneema™ArmourWeb section(2) can take high downhaul tension and is critical in stabilizing the profile entry, providing smooth bridging between UltraCams. A tapered strip of Tetoron™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.

Quadruple Luff Panel Layout

EVOX 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 response of the sail. Introducing this stable leading edge platform allows very high downhaul loads and integrated clear pocket construction.

Leading Edge Rib

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.

Seamless Leading Edge

Removing any stitching that could come in contact with the mast. 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.


Carbon Leech Mini Battens

Provide maximum support with minimum weight.

Kevlar Batten Bridges

To distribute the high downhaul load crossing the battens.

Visual Trimming System

Downhaul tension guide. Max. and Min. Recommended leech release points. Located on the upper leech between battens #2 and #3.

Aerodynamic Boom Cutout Closure

Prevents the apparent wind from blowing into the mast sleeve and generating drag.

Dual Boom Length Compact Clew

Outer and inner clew position straight alignment. Retains same clew height and boom to mast rake on both clew positions, reduces weight and prevents rear part of the foot touching the water when jibing.

Batten Chafe Protection

Abrasion resistant PU print to help protect the battens from damage caused by rigging or boom contact.


Allowing easy rigging through loop to loop system and optimized adjustable outhaul function that reduces the friction and eliminates any crossing lines (crucial when using adjustable outhaul system).


Batten tensioner system allowing precise tuning and secured positive locking without the need for tools. Starting from the Top: #1 - #2 - #3 (Mini lightweight Batcams combined with tension adjuster set), #4 - #5 (Batcams combined with tension adjuster set) and #6 - #7 (Batcams combined with tube screw adjuster and Allen key for an extra tension system).


Suspended camber system improves sail rotation and acceleration out of jibes. Simultaneous tuning of battens and cambers makes sail tunable for different mast diameters and camber pressure.

Fuse Pockets

Overlapping body panels create a sleeve for battens, eliminating the need for traditional, separate batten pockets. This saves on unnecessary weight, simplifies construction and creates a fully symmetrical batten cavity, delivering a fully equal sail on both tacks.


Fiberglass tubes offer extra durability in areas more exposed to crashes. The progressive flex creates a deeper profile, essential in generating low end power and upwind performance. Starting from the Top; #1 - #2 (Single RDM Fiberglass tube) and #5 - #6 - #7 (Precision Tapered CNC 2-piece Fiberglass tube). Carbon tubes are placed in the central section of the leech, adding extra stability and preventing the profile from moving back. The lightness of carbon battens minimize the swing weight which increases the reflex of the leech. Starting from the Top; #3 (Single RDM Carbon tube) and #4 (Precision Tapered CNC 2-piece Carbon tube)
