4 CAM FOIL COMPETITION SAIL
The GS-F takes off into its third year. The focus of this race machine is still on absolute control and neutrality at maximum speed. The GS-F perfectly meets the special requirements of competitive and advanced foiling.
KEY FACTS:
> High-Aspect Performance Foil Sail
> Developed for foil racing and foil slalom
> 3D wingsleeve for instant acceleration
> New size grading and addition of foil speed sails
> Little twist and high shape stability provide pumping efficiency
> High number of carbon tubes
> 2 clew claws on clew for optimized boom height/position adjustment
With its pronounced sail foot, shorter boom, hardly any loose leech and relatively little twist, the GS-F adapts confidently to conditions that have changed compared to fin surfing. The 3D mast sleeve with its aerodynamic precision has been revised, it releases enormous forces when pumping and gets you in the air in no time. The fast lift is supported by the high number of carbon tubes and the associated shape stability of the sail. The lightweight sail construction and special outline ensure perfect positioning in flight. Once lifted off, the sail takes over like an autopilot and allows you to put your complete concentration on the race.
Foil windsurfing is evolving rapidly and Speed foilsurfing in strong winds is becoming its own discipline. That's why our R&D team led by Renato Morlotti has re-tuned the GS-F range in size gradation and added a 5.6 and 4.5 sqm sail for speed slalom use.
The new sizes 6.7 and 7.8 sqm have got an even larger aspect ratio than their predecessors. At the same time the top area has been reduced by approx. 15%, resulting in an overall increase in control and speed. Start your engine.
We would like to point out that the GS-F series is aimed at very experienced, competition-oriented foilers. The beginner and intermediate or the dedicated foiler can also choose from our other foil sails Raise, Flylite or Bow.

SAIL TECH
X-PLY
The all-time classic of the reinforced laminates. X-Ply does withstand higher punctual stress. In case of a cut, the threads avoid further damage. X-Ply is light, stable and has a good transparency. Therefore, it is used in the window area of the Wave- and Cross Over Sails.
SQUARE PLY
The Square-Ply is based on the same concept as X-Ply material. However, the threads are aligned in a 90 degree angle and the material offers a higher overall thread density. That allows us to reduce the thickness of the included monofilm to save weight, but ensure durability at the same time.
MULTI DIRECTIONAL X-PLY
Multidirectional X-Ply is used in high stress areas. The thread layout shows a higher density of polyester yarn, thus making the material more resistant than the regular X-Ply. The additional vertical thread direction allows the material to take more tension and force in the critical tension line.
TENSION FRAME
The Tension Frame forms a functional unit with the smart clew construction. It holds the force from the clew and distributes the tension with the additional warp lines into the sail. The layout of the Tension Frame is designed to support the individual profile of every sail. Conclusively it improves the response of the sail and increases the profile stability. The stability of the construction ensures long term consistent sail characteristics.
KEVLAR STRETCH CONTROL
The targeted use of Kevlar Warp laminate allows us to precisely determine the stretch characteristics of each sail, ensuring a consistent sail profile and more response. The extremely light, unidirectional Kevlar threads have a very low stretch, even under highest loads. They are specifically positioned in each sail depending on its area of use. With Kevlar Stretch Control you will permanently find consistent characteristics and performance in your sail.
REDUCED BOOM LENGTH
On the more performance-orientated flatwater sails, the RBL cut is made directly on the batten above the clew and the eyelet is shifted inwards by up to 12 cm.
REDUCED BOOM LENGTH
For wave and cross over sails as well as for the freeride sail Zoom, a concave cut is used from the batten above the boom to the clew, reducing the distance from the mast to the clew.
SYMMETRICAL BATTEN SYSTEM
The alternating arrangement of the sail battens on the front and back of the sail allows a balanced tension and weight ratio. With this feature you have the same sail feeling, no matter which direction you are driving.
CROSS BATTEN CONCEPT
Often used in flatwater sails with a big surface in the boom area. The longest batten of the sail starts under the boom and ends above the clew. In this area the deepest profile as well as the largest surface of the sail is located. The Cross Batten stabilizes this area, especially when pumping. The center of effort point remains stable.
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.
