Don’t have the right conditions for surfing? The Surf Foil is a water sport that will multiply your riding possibilities. No matter what the wave conditions are, you can have fun on an infinite number of spots. The practice of Surf-Foiling has exploded in recent years, and we understand why. This water sport consists of lying on a board with a foil, rowing and catching a wave, just like surfing. Once on the wave, the speed generated by your foil will allow you to take off and fly over the water. Close your eyes and imagine yourself skiing or snowboarding on 1m of powder! Feeling like you’re flying like a bird, that’s how soft you’ll feel.

Why start Surf-Foil?

First of all, this sport has the undeniable advantage of allowing you to experience surfing when the waves are soft and not breaking. It allows you to optimise
poor wave conditions, for example in summer when there is less swell and surfing on overcrowded spots can get boring.
Surf-Foil is also a way to disassociate yourself from the surfers on the line-up. You can go and enjoy the spots with fewer people, and sail in complete freedom, without constraints. The other undeniable advantage over traditional surfing is that the Surf-Foil allows you to multiply the number of waves caught during a session.

Indeed, it is possible to link waves, to accelerate, to fly on the soft zones, to return to the peak with ease. A well mastered pumping can make you go up and link more than 6 waves in a row! Everything becomes easier and more fluid.
As you progress you will find that Surf Foil is just as sporty as surfing and is great for your cardio. It is also the stage to go Downwind (in SurfFoil or SUPfoil) or surf-tracted with a foil.

How to choose your SurfFoil pack?

How does a Foil work?

The functioning of a Foil is similar to that of a underwater aircraft thanks to fluid dynamics. The speed of movement generates a lift force and allows for take-off. This is because a lift force is created on the front wing which allows the foil to take off. The higher the foil speed, the more the foil is “pulled” upwards. This is when you need to put more pressure on the front leg (or decrease the size of the front fin). The rear fin acts as a stabiliser and in some way balances the lift of the front fin. Your weight acts as a balancer between these two fins.

To learn more about how a foil works, we refer you to our article “How does a surf foil work?

Composition of a Surf Foil

The Foil consists of a mast, attached perpendicular to the plank and fuselage and two front and rear wings. The largest wing with a bulging top is at the front, where the leading edge is rounded and rapidly increases in thickness, then tapers to a thinner trailing edge. Finally, the rear stabiliser is similar in shape to the front wing but inverted, with a reduced surface and a different profile. The size of the stabiliser will determine the handling and speed of your foil.

How to choose your foil according to your practice and your level?

Each element of a foil can be selected and modified according to your needs.

To carve in Surf Foil, a front wingLow Aspect will run very fast, but will be slower and less efficient than a Medium Aspect. Indeed, the latter will offer you the advantages of a fast spinning foil, while being very forgiving and forgiving of all mistakes. As for the High Aspect models, these can be interesting because they are more efficient at pumping.

Front wing :

  • If you are looking for accessibility, a Mid or Low Aspect model such as the SROKA S Foil Classic will be ideal for surf-foiling with versatility, stability and carving with ease, for all levels. This type of carving model allows you to make beautiful curves with the pumping technique.
  • If you are looking for performance, the High Aspect model will offer you a better glide, with an equivalent carving if you reduce the length of the fuselage. Pumping is easy and allows you to reconnect the waves without difficulty. However, this requires a little more technique.

Choosing your front foil

As far as the stabiliser is concerned, the S-Foil’s is one of the best compromises between handling and stability. We are working on a larger range, to make the Foil more playful and to increase the navigation possibilities. (Available during 2021)

The mast :

The smaller your mast, the easier it will be to start. However, a longer mast will be more scalable over time.

  • A 70cm mast is ideal for learning to foil. Its relatively short size will forgive any positioning errors, and falls will be much less impressive.
  • An 80cm mast is extremely versatile. It will allow to evolve, to pumper, to surf, to manoeuvre more efficiently.
  • A 90cm mast is for the more experienced sailor looking for more technical and intense sailing. (this size is recommended for Downwind)

The fuselage :


Fuselages for the Sroka Foil

The length of the fuselage will have an impact on the handling of your foil:

    • a standard fuselage will provide more stability, pumping will be less physical but less manageable.
    • a medium fuselage will turn better, be more manoeuvrable but will be a little more difficult to pump. Indeed, it requires more frequency.
    • a short fuselage will be great for carving as it is very manoeuvrable but will require even more frequency when pumping.

How to choose a surf foil board?

There are Surf-Foil boards on the market in different sizes (from 4’2 to 5′). The bigger your board the easier it will be to row and surfsail, but it will make pumping more complicated (as there is more inertia).

At SROKA Company, we have developed a Surf Foil board in size 4’6 which is for us the size master key. Indeed, it will be perfect for beginners but will also allow experienced pilots to fly and pounce easily. With a rounded nose, and an overall compact volume under the paddling body, it is the perfect size compromise to learn, progress and perform in all conditions. The deck of the board is slightly recessed to lower the centre of gravity and increase your stability. In addition, it provides a perfect reference point for the positioning of the feet. The hull is designed with a double concave forward and a slim nose for easy ducking to increase the speed of the glide and to take on waves that have not yet broken. The entire deck of the board is covered with pads for added comfort and strength. Moreover, our Fast Flyer 4’6 is multi-supported, you can use it in WingFoil, Kitefoil and Wakefoil.

For 2021,we will offer a 4’2 Surf-Foiling board for experienced surfers. It is conceived and designed to be more manageable, easier to pump. Its performance will make it more technical to use when catching waves, as it requires better placement on the wave. It will be like its big sister, multi-support.

We have put the best of French know-how at your service. Our boards are made in Brittany and tested by Bruno Sroka, founder of the brand, and his team. This technique of production of surf-foil boards is more expensive but guarantees an incomparable quality and durability.

The choice of the foil according to the spot and the conditions

Pay attention to the choice of your spotlight. Indeed, this will vary according to your foil. It is imperative to provide a safety margin with the bottom under the foil.

Ask the locals or take a good look at the water. Waves that break very close to the shore will be more difficult to get up and out quickly. Waves away from the shore will be easier and will allow you to optimize your surfing time. De-program your way of thinking about your spot like in surfing. You don’t need a wave that breaks, you don’t need a big wave, look for all the waves that nobody wants (soft, that break and reform, a ripple…).

The spot does not need to have big wave conditions. This is the advantage of the Surf-Foil: you can get up on a wave with a gentle slope and less than 60 cm high. Depending on the spot, you can (if your technique allows it) start directly from the beach, and reach the peak with the beach start pumping technique.

In any case, a spot with little traffic is the best option.

In summary…

Choosing the right Surf-Foil pack will determine the way you foil. Our advice is therefore to take into account:

  • Foil choice: a classic front fin like on our S-Foil will be perfect for beginners or if you are looking for forgiveness and easy carving. Choose a High Aspect foil if you are an experienced surf-foiler, if you are looking for performance and to reconnect the waves without difficulties while maximising speed.
  • The choice of the mast : The smaller your mast ( 70 cm) the easier it will be to start. The ideal is to choose a standard model (80 cm), which will be more progressive as you progress.
  • Choice of fuselage: a standard fuselage will require fewer frequencies at the pumping. Conversely, a short fuselage will require more frequency but will turn better. The standard size of our fuselages at Sroka is 680 mm.
  • Choosing your board: a 4’6 size board is perfect for beginners but still versatile for the more experienced who want to pummel easily. A 4’2 size board will offer a lot of manoeuvrability for the experienced surfer.
