How to choose your F-ONE foil ?

At F-ONE
At F-ONE, there is no compromise on quality no matter the product. Our foil range is continuously expanding to remain the most comprehensive, modular, and accessible.
Our foil range follows logical stages of progression and clear steps that guide the customer according to their practice and level. These stages of progression, for example GRAVITY – PHANTOM – SEVEN SEAS – EAGLE, are invaluable for riders as they start and progress on equipment with similar balance. As the level of the customer increases, they can then choose more specific foils and focus on the discipline of their choice.
Here is our guide to help you choose your F-ONE foil. Keep in mind that your setup will vary depending on your skill level, your weight, the conditions, and your chosen program.
Aspect ratio
The Aspect Ratio (AR) is key to understanding how we constructed our range of foils, and it should be your first guide in choosing a front wing.
The AR is the ratio between surface area and wingspan.
Overall, foils with a low- to mid- AR will be a bit thicker and rounder. They are more stable, turn and pivot well, have plenty of lift, and will help you take-off easily at low speeds or in low wind conditions. Those with a high AR will be thinner and longer, and thus produce less induced drag. They are highly efficient and will provide a lot of glide and speed.
The higher the AR, the better the foil performs for experienced riders and the further it flies. However, it also requires more minimum speed to start planing and develop lift. The AR also influences the turning radius of each foil. With equal areas, a higher AR makes wider turns. Finally, there is also a link between the swell period and the AR of the foil. The longer the swell period, the more AR you need.
Aspect ratio
Range presentation & programs
In our foil range, we based everything on aspect ratio. As we started designing and trying out high aspect ratio foils, we discovered they opened new programs and new possibilities.
Overall, we have classified our range in four levels of AR to define programs for the foils:
The most versatile and best performing is the AR 6.0. Its medium span guarantees maneuverability for surfing and accessible pumping.
When you switch to an AR of 7.0 or 8.0, you increase your maximum speed and will glide further. Some of our foils in that AR range also provide a fine balance between glide and maneuverability, which is perfect to surf and to push through the carve.
The AR of 9.0 and above is, in general, reserved for experienced riders. It offers incredible glide if you maintain sufficient speed and brings good maneuverability under 1000cm².
Ultimately, for wing and surf foiling, our range starts at an AR of 5.0 with the GRAVITY and goes all the way to 12.0 with the EAGLE X. For dock start and pump foil, we also offer the JAM with an AR of 10.
In kite foil, we have three different models with low- to mid-aspect foils that are perfectly adapted for high winds and high lift conditions.

Front Wings
Wing foil, surf foil, and downwind
Our range of foils for wing foiling, surf foiling and downwinding has considerably expanded over the years.
PHANTOM-S
As you continue improving and want to change up your ride, a foil with a high AR will bring more speed, great carving capabilities, and more acceleration. The PHANTOM S, with an AR of 6.5 and surface areas below 1000cm², has a thinner profile than the regular PHANTOM to give you more speed and maneuverability. If you’re a surfer, then the handling, maneuverability, and carving abilities of this foil are made for you. Both PHANTOM and PHANTOM-S are also perfect for freestyle wing sessions.
