Whether in Wingfoil or Surf foil, it quickly becomes interesting to make your foil more manageable. Indeed, many foilers, after a certain level, wish to trace curves without concessions, to increase their gliding sensations and to widen their possibilities. To continue to progress it can be interesting to make your foil more manageable. In this article we explain you how to gain in maneuverability through 4 options.
First of all, you have to understand that by gaining in maneuverability you will lose in stability. This is unavoidable. We could draw a parallel with an airplane: the longer the wings of the airplane, the more stable it will be, but it will take much longer to turn. If the wings of the plane are shorter, it will turn much more easily but it will be much less stable. It’s the same principle for your foil, by reducing the wingspan, it will be more maneuverable and less stable. In this way, by playing with the size and shape of the various components of your foil, you will gain in maneuverability.

Option 1: Modify the front fin

The handling of a foil is closely related to the span and shape of the front fin. So the first step is to reduce the surface area of the front fin. You will lose stability but you will turn much more easily. The shape of your front fin will also affect the stability of your foil. A flatter fin, with a high aspect ratio (S-Foil HA Ratio), gives more stability but less handling. With the same wingspan, for more handling it is better to go for a stockier, slightly curved fin with low aspect ratio (S-Foil Classic fins). Indeed, Classic fins are naturally more maneuverable because of their shape. HA fins are more efficient and therefore require more experience to control them and enjoy superb handling.

Option 2: Change the length of the fuselage

The longer the fuselage, the more stable the foil. Reducing the distance between the front fin and the stabilizer will make the foil more manageable. Short (62cm) and ultra short (56cm) foils will give you tight turns in waves and radical maneuvers. They are however much less stable longitudinally and require a higher pumping frequency. They are more suitable for intermediate or advanced foilers.

Option 3: Reduce the surface of the stabilizer

As the name suggests, the stabilizer is there to stabilize your foil. The larger the stabilizer, the more stable your foil will be. So, by reducing the size of the rear fin you will gain speed and turn more due to the reduction in drag.

Option 4: Play on the length of the mast

At Sroka we have four lengths of mats, 55cm, 70cm, 80cm, and 90cm. The standard masts are the 80cm masts. However, if you have modified the three previous options, your foil will have lost a lot of stability. To compensate for this loss of stability you can opt for a shorter mast. This will give you more comfort and stability. The longer the mast, the more sensitive it is. So by reducing the length of the mast you can have better support, while keeping a strong handling with a small fin, a small stabilizer and a short fuselage.

A good construction for a better handling

We have chosen to develop poles that are reactive and playful while maintaining control. The shortened chord of our masts will allow you to gain in maneuverability to offer you sensational curves. Its aluminum construction guarantees excellent rigidity, so your foil will be more responsive and more manageable. With this design, the twist phenomenon is reduced, so the foil keeps its control.

Do we have to change everything?

Each option can be combined with another. However, it is not necessary to act on all the variables at the same time to make your foil more maneuverable, a single parameter can change everything. When you want to gain in maneuverability, you lose in control and stability. So you have to compensate, change other variables to regain stability. For example, if you have a very small wing like a 670 or a 700, you can keep a standard fuselage to keep some stability. This way you will regain control and you will be able to accelerate more.
