PROGRESSIVE HIGH ASPECT RATIO DESIGN

With the 2020 series of the RS: Racing EVO are introducing the high aspect ratio design that could already be found on the flight Evo. While the high aspect ratio is much more defined on the bigger sail sizes, it is less so defined on the smaller sizes. Thanks to this progressive high aspect ratio design, we are fully leveraging this design’s benefits. The sails become equally controllable on foil as well as on fin.

COMPONENT SLEEVE CONSTRUCTION

Combining different materials in the sleeve sections allows designers 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 team 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.

TWIST SHAPING CONCEPT

Just like its predeccesors, the sail twist allows more release, so you feel like you have gained an extra gear. The EVOXII 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.

MAST SLEEVE WINDOW

Clear window in the mast sleeve for better visibility during racing. Especially when arriving at the first buoys. This was the most required feature from team riders to improve racing.

CARBON LEECH MINI BATTENS

Provide maximum support with minimum weight.

VISUAL TRIMMING SYSTEM

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

DUAL BOOM LENGTH COMPACT CLEW

Has been slightly improved and redesigned to avoid contact of sail edge body with the boom. 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.

CARBON COMPOSITE BATTENS

Carbon tubes are placed in the central section of the sail body, 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 which is something really unique in this sail.
Starting from the Top;
#1 - #2
(Single RDM Fiberglass tube)
#3
(Single RDM Carbon tube)
#4 and #5
(Precision Tapered CNC 2-piece Carbon tube).
#6 - #7
(Precision Tapered CNC 2-piece Fiberglass tube).
Besides the Carbon tubes in the central section of the sail, additional 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.

BATCAMS

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).

LOOPSTERS

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).

ULTRACAMS

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.

KEVLAR BATTEN BRIDGES

To distribute the high downhaul load crossing the battens.

AERODYNAMIC BOOM CUTOUT CLOSURE

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

BATTEN CHAFE PROTECTION

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