Foil Stab Curve V2
The stab for a total control in curves.
Program
The stab for a total control in curves.
Introduction
The Curve stab offers the best blend of ease, control and maneuverability.
It is the perfect stab for foilers looking for maximum performance in curves. This is what this stab is all about, it is both maneuverable at low speed and super stable in long curves at high speed. It’s behavior is very healthy thanks to a grip that acts to keep the foil on its trajectory.
The foil will be both very maneuverable and very controllable. It locks into the trajectory and allows you to push hard in the curves with a feeling of total control.
Just like the Curve front wing, the goal of this stab is to be predictable and to guarantee you total control in surfing. That also applies to long speed runs in wing foiling.
An accessible and compact stab that will boost your progression without ever restricting your performance.
Curve stabs in sizes 36 cm, 39 cm, 43 cm, 46 cm, 49cm and 53cm will allow you to have fun whatever the sport, be it kite, wing, surf or SUP foiling.
Choosing the right size
Curve stabs are accessible and will be the perfect complement to a Curve, but they can work very well with other front wings if you feel that you need a stab that promotes control in carves.
Choose the size you usually like from GONG. Always adjust the size of the stab to the size of the front wing for a balanced flight. A stab L with a front wing L will give a perfectly balanced set up.
Your benefits are clear:
- An efficient shape created by one of the leaders in the Foil world.
- A design at the cutting edge of R&D and ahead of its time.
- A construction proven on thousands of foils.
- The “Full Options” finish at a crazy price.
- A light, solid foil, with one of the best technologies on the market!!!

Outline
The curved outline of the stab projects its tips backwards: there is more leverage on the front wing which brings a lot of stability in the pitch axis. This allows you to press hard on the back foot with no risk of a sudden stall. This stab brings a lot of confidence and allows you to focus on what really matters: drawing perfect lines.

Profile
The profile has a moderate volume, distributed over its entire wingspan. It is perfectly balanced between lift and glide. It’s really great for maintaining speed in bottom turns or for maneuvers in wing foiling.
Type of profile
The profile of the new Curve stab is relatively thin in proportion to its chord. It is a profile that allows you to fly at low speed and brings a lot of lift in pumping or maneuvers, it never stalls!
The max width of the profile has been significantly moved back compared to the previous Curve stab. You gain a lot of glide and top speed, but also more roundness in its behavior (less ON/OFF).
The rear third of the extrado is the key point of this new profile. With more volume there, the stab lifts more for the same effort. It offers a little less top speed but a lot more length between two pumps and a lot more lift at low speed. Another stunning point: It recovers from a stall incredibly well.
Dihedral
The negative dihedral in the center of the stab gives it a clear grip for a super predictable behavior that really gives you confidence. In addition, it keeps the tips away from the surface of the water so it greatly reduces the risk of breaching the stab on the surface. Just like a surfboard with a simple concave, the point is to hold on to the water. It’s really a stab for carving and not for snapping.

The combo with the winglets makes it super safe : you can push in the legs and put a maximum of power without stalling. Be it in curves or at high speed, they provide a real gain in stability.

Fuselage
This stab is only compatible with our titanium or aluminum Pro fuselages. The tail of the stab in full carbon allowed us to optimize the shape of this part of the foil. The drag was significantly reduced as well as its weight. The rear portion of the fuselage and stab are made of one piece. It is ultra streamlined to reduce drag by 3. This is a true Pro fuselage which unbridles all the front wings of the range. The gain is of 3 to 5 knots in top speed compared to our V2 fuselage.
This slender back end of the fuselage is so efficient that it boosts handling by generating less drag. Its very small section next to the stab makes it much easier to drift and cut turns short.

The fillets connecting the fitting to the profile have been optimized for more glide. But they also prevent twisting for perfect stiffness.
The trapezoidal fitting system with the Pro fuselage ensures perfect firmness of the assembly without the need for counter-screws. The whole thing gives a very nice foil, light, rigid and devilishly efficient!

Buying guide
For whom?
It is a stab for intermediate level foilers who want a playful foil that provides maximum control in maneuvers.
- In surf foiling, you should already know how to take off but it is easy and reassuring. The stab will allow you to progress a lot without slowing you down, and this for many sessions to come.
- In wing foiling, you should already know how to fly and stabilize the flight. The stabilizer offers amazing control and helps a lot to sail upwind. It offers a great lift/glide balance which makes working on maneuvers very pleasant.
- In kite foiling, you can learn with it or you already know how to sail. It is perfect for charging and having perfect yaw stability. It’s super predictable.
What for?
These stabs have been designed to make the most of waves, linking turns and maintaining speed. It is also great to work on maneuvers in flat conditions, be it wing or kite foiling gear.
With a generous and very well thought out profile, it is a stab offering a great glide/lift compromise. Its dihedral and its winglets make it super playful and the control is total.
- In surf foiling, it is clearly the ultimate stab to link turns like you would on a shortboard. It offers traction and carves hard, meaning a soft wave will never be boring again.
- In wing foiling, it is a comfortable stabilizer, reassuring and offering great maneuverability.
- In kite foiling, it’s great for getting comfortable at high speeds, with constant control.

Which quiver?
The Curve stab is very versatile. You can mount it on a large board but it will reveal its true potential on shorter boards where rail to rail is preferred.
Positioning of the foil?
For beginners on GONG foils, place the plate in the rear third for surfing, SUP and kite, and in the middle of the US rails for wing foiling.
The further you move it, the more it pitches the board up. The more you move it back, the more the nose of the board dives.
With these high ratio stabs, we will probably have to move it forward as they carry very little. Do not put it too much forward eather, it would generate a weird feel and would in fact be a sign that your stab is too small. This could induce whistling of the foil despite a perfect trailing edge.
Be careful not to move it too far forward. We often tend to forget to use the back foot, especially when we have a kite foil background. However, moving the foil back a little forces you to put more weight on the back foot and gives a more harmonious attitude and reduces effort.
