4 CAM COMP SLALOM SAIL
This year again, the World Cup sail GS-R, continuously optimized by sail designer Renato Morlotti, will enter the race. The speed machine convinces with breathtaking performance, enormous planing power and maximum top speed.
KEY FACTS:
> World Cup Fin sail
> Augmented Aerodynamics through 3D profiled mast sleeve
> 7/7 Cross-Batten-Concept, airflow aligned battens and neoprene cover at boom cutout
> Two offset clew claws for more trim flexibility and easy use of a trim system
> Tack Strap, regulates downhaul tension and improves profile efficiency
> 5.0 / 5.6 / 6.3 sqm RDM only
The R&D team around sail designer Renato Morlotti focuses on the GS-R, besides drive and acceleration, especially on technical and physical controllability. And this in constant dialogue with our GUNSAILS team riders and always with the goal of optimizing speed and acceleration even further and guaranteeing perfect handling. Speed is king! That's why the small sizes up to 6.3 sqm get a complete redesign this season. Innovative mast sleeve design, completely reworked profile and modified outline eliminate the speed limit. With the lighter sail feel and absolute control in strong wind conditions, the GS-R can push the limits in both slalom and speed events.
In order to focus not on the sail, but on the race, the GS-R's configuration is crucial: 4 smooth rolling cams, a batten configuration made of lightweight tube battens and a stable draft point ensure optimal handling and perfect control. A 3D wingsleeve made of Square-Ply, unidirectional Kevlar strips inside and a luff panel made of strong X-Ply material keep the GS-R's profile perfectly in shape. Also test reports confirm - Unlimited performance at the push of a button and a reliable companion for every World Cup race.
Let's start the race!

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.
▶SAIL FEATURES
F.R.E.D.
F.R.E.D. will help you to find the optimal downhaul trim for your sail. The mark is located in the upper sail window. Simply trim the downhaul rope until the loose leech reaches the FRED mark.
TOP GUARD
The large reinforcement at the sail top avoids abrasion and wearing out whilst rigging.
VARIO TOP
With some sails a Vario Top is used, which also allows the use of a longer mast. An additional loop is sewn on top of each sail. It serves to hook in the sail if you want to pull out the mast.
MINI BATTENS
Lightweight mini battens take control of the leech while twisting and avoid detrimental leech flutter. By that, the window fabrics are prevented from damage and the longevity of the sail is increased.
BATTEN GUARD
PVC logo labels on the batten pockets prevent wearing out and abrasion whilst rigging.
INTERNAL TRIM BATTEN
The Internal Trim Batten system is completely integrated into the batten pocket. The battens can stay tensioned in the sail. The fine adjustment ensures an optimal trim. The profiled end piece offers additional protection against abrasion. An Allen key to tension comes with each sail.
BOOM POSITION CONTROL
The printed height scale at the boom opening helps you to easily remember your personal boom position.
SLEEVE VOLUMER
The sewn PVC label keeps the mast sleeve open at the boom opening like a clasp making it easier to insert the mast.
DOUBLE LOCK SEAMS
Double seams form the most stable connection between individual panels and different materials. They are used in stress zones as well as in areas of high tension and make your sail robust and durable.
MAST FOOT PROTECTOR
The new two-piece mast foot protector offers more protection for mast and board. The loop makes it easier to pull down the sail.Through an opening, the uphaul can be conveniently guided inside the protector. There is a mesh pocket on the inside. Excess rope etc. can be stowed here.
COMFORT PULLEY
The integrated triple pulley has large easy turning stainless brass rolls which greatly reduce the effort required for sail trimming.
TRIM SETTING
The luff length is patched on the mast protector. The boom length is also printed beside the clew.
OFFSET CLEW
Horizon and Raise sails are equipped with two clew eyelets which are set asymmetrically for individual tuning.
> Upper eyelet for more power
> Lower eyelet for more control
POCKET GUARD
A PVC braid sewn onto the bottom batten pocket protects the sail from abrasion when waterstarting.
STRAP ON
After rolling up the sail, simply attach the bungee rope and the sail can be stowed away easier and is more space-saving.
FOOT GUARD
All seams in the significantly stressed foot area are protected by Dacron coverings. A PVC edging at the sail foot protects the leech edge against your board’s nonslip coating.
