The easy stab to fly forever.
Introduction
The Sirus stab is the extreme aspect ratio stab designed to provide maximum glide and lift at low speeds.
In lightwind conditions, for pumping, and in small waves, this stab significantly improves the speed-to-energy ratio.
Despite its large wingspan compared to its surface area, this high aspect ratio stab is paradoxically designed not to hinder rail-to-rail performance. Similar to the Sirus front wing, the volume and surface area are centered beneath the foiler’s stance. This allows the extremely thin tips to be free, enabling precise and effortless foil control. This design saves the rider a considerable amount of energy.
The fuselage is elongated along the stab section as it increases in size, enhancing leverage on the front wing. The foil maintains a stable and long glide, reducing the frequency of pumping oscillations, thereby minimizing strain on the rider’s cardio and achieving record-breaking distances!
The profile of this stab is nearly symmetrical for optimal glide. However, the angle of attack is the highest in the range to keep some lift. Ideal for pumping, light wind, and small wave conditions, this stab offers impressive glide and exceptional lift!
When combined with our large front wings, you will shatter your records!
Choosing the right size
The Sirus stabs are versatile and will be the perfect complement to a very large front wing. They are highly effective at low speeds and will increase your pumping efficiency and glide.
For Wingfoiling or SUP foiling, always match the size of the stab to the size of the front wing for a balanced flight. An XXL stab with an XXL front wing will create a perfectly balanced setup.
During dock starts or flat starts, you will need to consider your riding speed when selecting the setup. At low speeds, such as during a flat start with a giant front wing, a smaller stab will be more maneuverable and create less drag. However, your front wing won’t reach the speed at which the pitching couple comes into play. If your goal is endurance, maintaining a good balance is still necessary.
Construction
Our wings and stabs are made of 90% Prepreg 12K carbon, with more than 15 layers of carbon fiber in total. High tension points such as the joints and connections are reinforced with Kevlar to resist tearing and glass for tolerance. Molded at high pressure and high temperature on a foam core, our wings and stabs are practically indestructible. Both rigid and floating, they are the perfect balance between contained weight and infinite durability.
All our wings and stabs have soft “tips”. Their ends are rounded and bulky to minimize danger. We still invite you to exercise great caution. Similarly, the trailing edges are blunt to avoid being sharp.
Wing tips are a potential source of danger. We take care not to produce an intrinsically dangerous design, within the limits of efficient hydrodynamics. The trailing edges can be sharp (the only solution to achieve the expected performance by users), especially if they are damaged or if you sharpen them. We invite you to be extremely careful despite these precautions because these parts remain sharp and dangerous by nature. Stay away, wear the proper protections, and never sharpen them. Systematically repair the slightest hitch in the outline because it represents a danger for you and others if it were to cut your leash for example. In all situations, the greatest caution is required. If in doubt, abstain (waves, strong wind, etc.).

Shape
The shape of the Sirus stabs is designed for maximum efficiency in low-power environments, such as light wind, pumping, and small wave conditions.
Outline
Despite the large wingspan of the stab, the outline is designed to promote rail-to-rail performance and not hinder precise drive. The outline is curved towards the rear, and the trailing edge features a reverse omega shape to slim down the outer third and unlock the tips.
Profile
The profile is nearly symmetrical, with a slight concave shape on the underside to combine glide and lift. It offers the perfect balance to create a stab with low drag, capable of accelerating well beyond its low-end range, while also generating lift at low speeds.
Type of profile
The profile of the Sirus stab is nearly symmetrical to minimize drag and provide maximum glide. Compared to the other stabs in the range, this one has a more pronounced angle of attack to deliver increased lift during flight, but most importantly, to effectively keep the foil high between each pump.
Camber
The camber is slightly negative at the tips to reduce ventilation given the large wingspan. The grip is solid, providing complete control in large turns. It is easy to relaunch the foil during pumping maneuvers. Ideal for taming the wide turns of the largest front wings.
Fuselage
The fuselage is 5cm longer compared to a Fluid H in larger sizes, which helps limit pitch and allows for very solid support during pumping (both during takeoff and in flight) without losing balance. The rear section of the fuselage is sized proportionately to the surface area of each stab, ensuring maximum rigidity and durability.

Buying guide
For whom?
This stab is designed for intermediate to expert foilers who want a high-performance stab to maximize their flight time during sessions, whether it’s for dock starts, surf foiling in small waves, or wing foiling in light wind conditions.
What for?
These stabs have been designed to allow you to increase the number of sessions you can have throughout the year. The days when the waves and wind were too weak to do anything are now a thing of the past.
With a clever profile and fuselage design, they enable early takeoff, accommodate a wide range of riding speeds, and are highly efficient during pumping maneuvers.
Which size?
The Sirus stabs are quite user-friendly despite their high aspect ratio. Choose the size that you typically prefer for your GONG gear.
Always adjust the size of the stab to match the size of the front wing for a balanced flight.

What quiver?
The Sirus stab will unleash its full potential when paired with a large pumping-specific front wing and a board designed for maximum glide like the Cruzader.
Foil positioning
For beginners using GONG foils, place the foil plate at the rear third of the board for surfing, stand-up paddleboarding (SUP), and kiteboarding. In wing foiling, position it in the middle of the US tracks.
The further forward you place the foil, the more it will pitch the board upward. Conversely, moving it back will cause the board’s nose to dive.
With high-ratio stabs like the Sirus, you may still need to move the foil forward often as they provide less lift, especially at slower speeds. Be careful not to go to the extreme, as it can result in an odd ride and may indicate that your stab is too small. This could lead to whistling noises despite having a perfect trailing edge. It’s common to neglect the rear foot’s role, especially for those transitioning from kite foiling. However, moving the foil back a bit forces you to put more weight on the rear foot, resulting in a more harmonious attitude and reduced effort.

Warning
The practice of the sport Foil may expose you to serious injury. A poor mastering of Foil may lead to cut, serious injury and/or including death for you and/or others.
Foil should be practiced by taking into consideration all kite user precautions that are associated with the sport Foil. Remember that a Foil is long, cutting, and reaches high speeds. Getting hit by a Foil, or hitting someone/thing can have dramatic consequences.
Always Foil far from others, in a secure and safe waterscape without obstacles.
Foil is most often practiced in light winds which may cease to blow leading you to return to shore by swimming. As a consequence do not overestimate your your strength/capacity : never go further out than your skill and swimming capacities and wind conditions allow.
Always wear a helmet and life vest for floatation. Always wear a full body wetsuit.
When handling the Foil, be careful not to cut yourself along the edges.
GONG is NOT responsable in case of any and all accidents implicating a Foil GONG. The practice of Foil is undertaken under the complete responsability of the Foil User/Practioner.
