Engineered for Maximum Speed
The GS-R is our uncompromising World Cup slalom sail, designed to deliver blistering speed, exceptional early planing power and ultimate control. Developed by sail designer Renato Morlotti and constantly fine-tuned in close collaboration with our team riders, the GS-R is built for technical mastery, allowing the rider to focus entirely on the race.
KEY FACTS:
- Maximum Stability and Control: A self-regulating, stable profile for breathtaking speed over long distances
- Explosive Performance: Outstanding acceleration and consistent drive across all wind ranges, ideal for fast starts and top-end speed
- Efficient Power Delivery: Pronounced loose leech for smooth gust absorption and effortless acceleration
- Trim Flexibility: Two staggered clew positions for versatile tuning options and easy integration with trim systems
- Tack Strap: Optimizes foot tension and improves overall profile efficiency
- Balanced at High Speed: Perfect balance of dynamics, stability, and lightweight construction for peak efficiency
▶Stability Meets Explosive Acceleration
The advanced 3D wingsleeve mast pocket made from Square-Ply ensures a stable profile, while the four smooth-rotating cams and full tube batten configuration deliver a consistent, predictable feel. These features not only guarantee top-end speed but also provide incredible stability across all wind conditions. The GS-R excels particularly in lower wind ranges with its exceptional acceleration and remarkable stability—key advantages for match racing.
Comfort and Control at High Speed
The GS-R's unique balance makes it feel like it's running on "autopilot," adjusting perfectly to the wind without overwhelming the rider. Its optimized shape and large loose leech absorb gusts, keeping the sail calm and allowing the board to stay effortlessly on course. Cam rotation is smooth, enabling fast, powerful maneuvers—ideal for quick gybes and dynamic re-entry. Despite its impressive performance, the GS-R remains comfortable and manageable without requiring excessive physical effort—perfect for World Cup racing and long sessions alike.
Performance for All
The GS-R isn't just for professionals. Its high stability and balanced profile also make it accessible to ambitious recreational racers who seek maximum performance with minimal effort. The sail delivers remarkable speeds with easy handling, making it perfect for anyone who wants to make the most of long runs while maintaining precise control and superior glide.
GS-R: Master the Wind, Master the Racecourse.

KEY FEATURES
1. TACK STRAP
Ensures improved downhaul tension and maximises profile efficiency for a stable and controlled flight.
2. 3D WING SLEEVE
The aerodynamically precise mast sleeve for maximum dimensional stability and outstanding performance at high speeds.
3. ROLL CAMS
Four smooth-running roll cams for optimum profile stability and effortless rotation - ready for maximum speed and control.
4. ZIPPER OPENING
The zip openings allow you to easily access the camber and roll it gently during assembly.
5. NEOPRENE COVER
The boom cut-out is closed by a neoprene cover. This reduces wind incidence and water ingress into the mast pocket and improves aerodynamics.
6. OFFSET CLEW CLAWS
Two offset claws for individual adjustment and perfect control in any wind strength. Ideal in combination with a trim system.
SAIL TECH
3D WING SLEEVE
The aerodynamically optimized mast sleeve resembles the shape of a wing and allows maximum power development of the sail. An additional Kevlar Warp laminate sheet in the middle of the mast sleeve functions as an anchor and keeps the 3D profile in its specified shape. This keeps the centre of effort stable at all times and the sail accelerates effortlessly.
ZIPPER OPENING
Due to the zipper openings you can easily access the cambers and roll them smoothly to the mast during rigging. Tuning with spacers is also made easier because of that.
KEVLAR STRETCH CONTROL
By using Kevlar Warp laminate, we can precisely determine the stretch characteristics of each sail, which ensures a consistent sail profile as well as more response. The unidirectional Kevlar lines show very low stretching even under high forces and are specifically arranged for each sail depending on its area of use. You will find constant characteristics and performance in your sail.
OFFSET CLEW CLAWS
Since we have already made very good experiences with the Clew Claws at the Bow Sail, they are now also used in the GS-R. You can easily hang the rope in the plastic claws screwed to the clew. It glides in the claw almost smoothly in a guide. In combination with a trimming system on the boom, you don’t have to thread much longer. The offset Clew Claws provide maximum trim flexibility. The upper variant provides an ergonomic advantage in light winds and gives you the best possible grip for pumping and planing. The lower claw ensures more control in medium and strong winds.
BATTEN MATRIX
The right type of batten in the right position is a decisive factor in influencing the profile. We use three different tube diameters to precisely control the profile in wind conditions. Light 9 and 11 mm tubes in the top area to control the twist, stiffer 14 mm tubes in the boom area where the sail pressure is at its highest. In the entire GS-R line, only short batten tensioners are used to further weight savings.
ROLL CAMS
The Rolls of the camber are placed on the outside. Once in position, the rolls reduce friction on the mast and the rotation becomes much softer. Four different cambers are available depending on position and mast diameter. By changing the cambers and using different spacers the sail setup can be changed from RDM to SDM, e.g. on the 6.3 sqm GS-R. You can find out whether a conversion is possible from the respective sail chart. Tips for your individual conversion can be found in our Blog at Rigging Guide.
TACK STRAP
Performance oriented sails like GS-R, Vector, Bow and Foil sails GS-F and Raise are equipped with a tack strap. You can use it to adjust the sail foot tension and reduce the twist to Lee to gain even more performance.
NEOPRENE COVER
The boom cut-out is closed by a neoprene cover. This reduces wind entering the mast sleeve and improves the aerodynamics. In addition, less water gets into the mast sleeve.
