Indeed, if you have mastered the Stand-Up Paddle and you want to start foiling, we advise you to start with the SUP-Foil. This will help you to start discovering the foil, to understand and analyze how it works. You will quickly feel the incredible sensations of gliding and speed that this water sport provides. The feeling of freedom and escape when you fly over the water. This will open up the opportunity to discover Downwind in SupFoil over tens of kilometers ,with the only sound being the breath of the wind, it’s just exceptional. Here are our tips for choosing the right SUP Foil.

What is SUP foil?

The practice of SUPFoiling consists of flying with a Stand-Up-Paddle board mounted on a Foil, and using a paddle to gain speed to take off. The volume of the board allows you to start directly standing while paddling with the paddle to catch a wave.

How do I get started with SupFoil?

First of all, starting out in foiling requires a minimum of technique and mastery. That’s why it’s advisable to start foiling with SUPFoiling. Indeed, the paddle board is bulkier and more stable than a kitefoil or surf foil board. Although this practice is accessible to everyone, we advise you to have a good foundation in SUPsurfing. It’s complicated to start directly with a foil. This practice requires a lot of accuracy, especially for the positioning of its center of gravity. In fact, it can be dangerous if you don’t do the right thing.

If you want to start alone, we advise you to choose very soft waves that break little, with little power. Also avoid crowded surfer spots to avoid conflicts on the water. Ideally, it is interesting to take lessons to learn the practice, especially to overcome the apprehension of falling on the fin and to understand the mastery of the flight height.

For more information, we have taken the time to give you all our advice on how to choose the right spot when you are just starting out in SUPFoiling in this article.

How to pump in surf foil?

Surf foil pumping is a technique that consists of making the board fly on the water using the strength of the legs and the movement of the foil. This makes it possible to take advantage of the potential of the foil, connect several waves and glide on almost invisible waves.
Here are some tips for learning how to pump in surf foil:
  1. Get out of the wave at the right time, preferably when it’s flat or before it breaks.
  2. Make a wide, smooth turn to maintain maximum speed and inertia.
  3. Look far ahead, towards the wave or target you are aiming for.
  4. Coordinate your arms and legs to give the foil a boost and make it go up and down.
  5. Lighten up on the board and let the foil accelerate on its own.
  6. Alternate phases of pressure and lightening on both legs.

How to choose the right Sup Foil pack?

SUPFoiling offers many advantages and in particular the fact that you can have fun in many conditions, even with 50cm of wave. Downwinding is even faster with this practice. It’s also a complete and interesting sport for cardio: with control, you go back up to the peak by pumping, you catch the waves, then you go back up by pumping, endlessly!

Are you looking for the SUPFoil equipment that will perfectly match your needs? SROKA Company gives you all its advice through this article. Our goal: to democratize the practice, by designing equipment that we enjoy using ourselves, all at an affordable price. (while building the boards in France)

All our answers to the questions you may have when choosing your Foil!

How does a Foil work?

The operation of a foil is comparable to that of an “underwater” aircraft thanks to fluid dynamics. The speed of travel creates a lift force on the front wing and allows the foil to take off. The higher the speed of the foil, the more the foil will be “pulled” upwards. Therefore, you need to put more pressure on the front leg, or decrease the size of the front wing. The rear fin, also known as the “stabilizer”, is used to balance the lift of the front wing. Be aware that your weight (center of gravity) will act as a balancer between these two fins.

If you want to know more about how a foil works, check out our article How does a surf foil work?


The Foil is composed of a mast, attached perpendicular to the board and fuselage and two front and rear wings. The front fin is the largest, with a domed top, with a rounded leading edge, which quickly gains thickness and then tapers to a thinner trailing edge. At the rear is the stabilizer, which is similar in shape to the front fin (but inverted), with a reduced surface area and a different profile. The size of the stabilizer determines the maneuverability and speed of your foil.

How to choose your foil?

In SUPFoil practice, an Low Aspect fin will rotate very fast, but will be slower and less efficient than a Medium Aspect. Indeed, the latter will offer you the advantages of a fast foil, while having a lot of tolerance and forgiving of all mistakes. As for the High Aspect models, these can be interesting, as they are more efficient at pumping.


  • A classic fin type S Foil Classic SROKA (Mid Aspect) will be accessible for all levels and very versatile. Beginners looking for lift and stability will head for the 1750 (XL) or 1500 (S). These two fins will allow you to sail in SUP Foil, Wake Foil or Wingfoil. It will be suitable for people around 80kg. The 1250 (M) will be faster and more manoeuvrable due to its smaller size.
  • A High Aspect fin will give you performance, but will require a little more technique. For those who want to take your SUP foil to the next level, the
    HA 1190 L (Lift)
    will provide lift and ease of gliding.

As for the stabilizer, the S-Foil is the best compromise between maneuverability and stability. We are working to offer you a wider range, and make your Foil more playful. (Available in 2021)

Everything you need to know about the differences between a High Aspect and Low Aspect foil

The mast:

The smaller your mast, the easier it will be to get started. Nevertheless, a longer mast will be more scalable over time.

  • A 70cm mast is ideal for beginners in learning to foil. Its relatively short size will be more forgiving of all your positioning mistakes, and falls will be much less impressive.

  • An 80cm mast
    is extremely versatile. It will allow you to evolve, pump, surf, and maneuver more efficiently.

The fuselage:

Fuselages for the Foil Sroka

The length of the fuselage impacts the maneuverability of the foil:

    • A
      standard fuselage
      will provide more stability, the pumping will be less physical but less maneuverable.
    • An
      average fuselage
      will rotate better, be more maneuverable but will require more frequency to pumping.
    • A
      short fuselage
      will be very manoeuvrable but will require even more frequency from the pumping.

  • Carbon paddles are the best paddles on the market in terms of quality. Unlike aluminum paddles that are likely to break in this type of practice, carbon paddles are both Lightweight and strong. LThe flexibility of a carbon paddle is more nervous than that of an aluminum one (depending on the percentage of carbon: 100% carbon and 50% carbon, they will be more or less rigid). For the practice of SUPFoil, or a sporty ride in SUP, we recommend a 50% carbon paddle for an optimal paddle, with the best quality-price-performance ratio.spec of SROKA paddles

Safety Tips:

The discipline of SUPFoiling can be dangerous, several precautions must be taken into account before launching.

Practitioners must:

  • Choose a spot that is deserted or with very few surfers around you.
  • Plan a spot where there is enough background (the longer your mast, the more depth it is necessary).
  • Choose a spot you know, to avoid the rocks.
  • When getting into the water, remember to position your foil upside down behind you and slide it on your back until there is enough depth to turn the board over and start paddling.
  • Look for soft and flat waves that roll out, these waves usually correspond to mid-tides. The ideal and fun waves in foil are the 40 cm waves up to 1m for the more experienced riders.
  • Do not hesitate to protect yourself by using a helmet, an impact jacket and any other mandatory or recommended safety equipment.

In short...

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

  • The choice of Foil: To start with, a classic medium-sized fin such as the Mid Aspect fin from SROKA (1750 for the largest sizes, 1500 under 85 kg, 1250 for a size of less than 70 kg) will be the most suitable. Are you familiar with SUPFoil and want to improve performance and technique? A
    High Aspect
    foil with a 1190 L fin will allow you to reconnect the waves without difficulty while maximizing your speed.
  • The choice of mast: Starting with a 70 cm mast will be easier. However, a standard mast (80 cm) will evolve with you for a longer period of time.
  • The choice of your board: rigid or inflatable, the larger the volume of your board, the more suitable it will be for beginners and larger riders. This type of model guarantees stability. Medium-sized models will be just as easy to handle, but will be more versatile and scalable in your progression. A board with a small volume will be light underfoot, easy to pump and will allow you to navigate with technique.
  • The choice of your paddle: carbon paddles will be the most suitable for the practice of SUPFoil, which is the perfect compromise between lightness and solidity.
