Frequently asked questions

What advice for security?

Windsurf foils are objects that achieve high speeds, and have sharp angles that can be sharp. Injuries can occur during falls or when handling the foil (launching, mounting). When mounting and launching, beware of trailing edges (wings and shaft) to avoid cutting yourself.
In navigation, during falls, we advise you to keep the boom in your hands, in order to avoid being ejected and the risk of falling back on the foil.
To reduce the risk of injury, we recommend wearing the following equipment:

  • Integral combination
  • Impact Vest
  • Helmet
  • Booties

By respecting these simple tips, you can enjoy your sessions without any worries!

Made in France ? Really ?

For AFS and Foil And Co, the words “Made in France” are not pronounced lightly.
All stages of manufacturing are carried out in France, next to Brest, in our own factory. We do our best to find our suppliers of raw materials in France, or at least in Europe to respect a “short circuit”, limiting carbon emissions, and in accordance with our desire to re-locate a production in France.
Our carbon is supplied by Distibution Composite (France) and is manufactured by Hexcel (Austria).
Our stainless steel inserts (box / fuselage) and our hardware come from Belgium.
Our cardboard packaging comes from France
By purchasing an AFS foil, you are sure to promote what French industry is doing best at the moment.

Compatibility of products in the future?

When designing the AFS-2, we took the utmost care to develop a reliable and optimized docking system, so that it lasts over time.

Thus, all our new wings are compatible with AFS-2 foils (a slight adjustment by sanding may be necessary), and all our new foils and wings are inter-compatible.

What maintenance for a 100% carbon foil?

Well…nothing ! Of course, if you want to keep it in its original state and avoid some oxidation phenomena (see next paragraph), we advise you to disassemble and rinse after each exit.
But rest assured, if you do not, the qualities, the resistance, and the life of your foil will not be altered.

Why is there no aluminum foil in the range ?

While it is clear that aluminum materials are attractive from a sales point of view for the sales prices they achieve, our experiments and tests show us that the mechanical properties and the service life of parts in aluminum exposed to such constraints (saline environment, forces exerted) do not correspond to the quality standard that we owe to our customers. The full carbon is the only way to have a powerful product with no life limit.

Why an oxidation deposit if the inserts are made of stainless steel?

After a few sessions of use, if you do not rinse your foil, you will observe a slight rust deposit on the inserts of housing or fuselage. Do not worry, all our inserts and screws are stainless steel, it is only a technical choice to have the longest life of your product that causes this phenomenon.
Explanation:
There are several qualities of stainless steel (A1, A2, A3, A4), A1 being the lowest (oxidizing over time, the less resistant), A4 being the best (not oxidized at all and being the more resistant).
We made the choice to use stainless steel A2 inserts (fuselage and heel), and A4 stainless steel screws. Indeed, if we had used screws in A4 and A4 inserts, no oxidation phenomenon would have appeared over time, but micro-welds could take place between the two parts in contact with water sea, with the impossibility of disassembling your wings or your foil from the board.
By mixing Stainless A2 and A4, we avoid this phenomenon of micro-welding, but observe a slight surface oxidation (the qualities of the piece are not altered). You can eliminate this oxidation by rinsing your foil after each exit or by cleaning the inserts with a brush and oxalic acid available in all hardware stores / drugstores.

Stall your foil in a deep Tuttle case

For obvious reasons of compatibility with the majority of the boards of the market, our windsurf foil is mounted in Deep Tuttle configuration.
For fin manufacturers, the deep tuttle should be 16mm wide at +/- 0.2mm. Our foils come out at 16mm / 16.1mm. We measured board boxes between 15.8 and 16.4mm wide. It is therefore possible to sand the side faces slightly to insert your foil in the box.
Note that it must still come in force to limit the game and the risk of breakage in the limp.

Why a fixed shaft / fuselage?

Simply for obvious reasons of rigidity, strength, durability of your product.
We do not want to make any concessions on the quality of our foils. With this system, the rigidity is optimal, it is both synonymous with performance (no latency in the reactions, transmission of efforts), and safety, since the more a foil is rigid, the more it is safe at high speed.
In addition, you have no risk of making play, loss of parts, which ensures an optimal life of your foil.

How is an AFS foil built?

An AFS foil benefits from a carbon prepreg expertise, with 2 main types of construction :

Hollow technology : This is our high end construction, A complete full carbon prepeg envelope, with carbon structure inside, and nothing else, just air inside.There is no foam whatsoever inside, no risk of opening, no aluminum. The strongest and lightest construction we can find on the market.

Monolithic technology : We stack Prepreg carbon layers in an aluminum mold that we press by heating it to a very precise time cycle and temperatures to achieve optimal mechanical properties. There is no foam whatsoever inside, no risk of opening, no aluminum.

The inserts are all stainless steel, and the shaft and fuselage inserts are molded at the same time as the carbon structure, for the best resistance and the best precision.

My foil whistles, why and what to do?

Contrary to popular belief, a whistling foil is a good sign. This means that the flow is laminar, and that the whistling is consecutive to the creation of a vortex at the exit of the profile (cf the work of Von Karman).
It is therefore perfectly normal for your foil to whistle, with different tones depending on the speed. These whistles come from the trailing edges (wings / shaft).
It is nonetheless true that it can quickly become unpleasant, and there are several solutions to remedy it (all applied during manufacture, but it can subsist on a new foil).
“Break” the trailing edge of the shaft by light sanding at 45 ° using a sanding block on one side (at 400 and then at 800 for finishing).
Perform the same operation on the trailing edges of the wings, extrados side,
If this is not enough, sand the surface foil slightly at 800 in the direction of the flow (avoid too much sanding of the varnish at the marking so as not to damage the sticker)
Attention these operations have several effects: Decrease whistles, increase the Vmax, but also make the edges of leaps sharp. Do it only knowingly. We are not responsible for any injury.
