LET'S TALK ABOUT FINS

THE MATCHING FIN DESIGN HAS A SIMILAR IMPORTANCE TO THE BOARD PERFORMANCE AS THE RIGHT MAST FOR THE SAIL.
THAT'S WHY WE HAVE SPENT A TREMENDOUS TIME AND EFFORT INTO SETTING UP A TRULY UNIQUE FIN RANGE.


THE 2 MOST INFLUENTIAL FIN DESIGNERS
With Dani Aeberli and Kai Hopf, the two Windsurfing fin designers with the most experience are responsible for our new fin range. Together, they represent over 50 years of expertise in fin design.


EXCLUSIVE SOFTWARE
We use our own dedicated fin 3d software. This software enables a perfect profile transition in the crucial tip area, where the fin sweeps backward. This is one of the secrets behind the outstanding efficiency of our fins.


EXCLUSIVE PRODUCTION
Setting up our own exclusive production was inevitable to take our fin performance to the next level. Every process is supervised on site by our own QC specialist Vasin Siritho to guarantee the highest level in quality and consistency.


FIN SPECIFIC TECHNOLOGIES
Instead of using the same technology for all our fins we are the only fin brand using 3 different technologies according to the fin length and range of use.

WHY OFFERING 3 DIFFERENT TECHNOLOGIES?

Here are the differences:

Injection molded fins are manufactured using a metal outside mold. Our exclusive CARBO_TECH material —a proprietary blend of thermoplastic polymer and carbon fibers— is injected into the mold under extremely high pressure and heat.

Advantages:
- Since this material is softer than G10 it's the ideal choice for shorter maneuver side fins to ensure the necessary tip flex despite the short length.

Disadvantages:
- For fins longer than 12cm, injection molded fins are too soft to ensure a proper performance.

Best suited for:
Injection molded fins are the ideal choice for short side fins.

G10 is an extremely compressed block of prepreg laminated fiberglass sheets. This block is placed in a CNC milling machine to create the final shape and profile.

Advantages:
- Due to its high-compression G10 is extremely durable.
- Easy to sand, allowing to repair damages caused by ground contact.

Disadvantages:
- The high-compression results in a higher weight, which is noticeable with longer fins.
- Not stiff enough for longer high-performance freeride/race fins.

Best suited for:
G10 is the ideal choice for medium-size maneuver center fins.

This is the most sophisticated method of manufacturing a fin. It is based on individual pre-impregnated (prepreg) fiber layers out of carbon and glass. These layers consist of single fibers that are laid side by side onto a carrier film and then pre-impregnated with resin by a specialized supplier in an industrial hydraulic press. This ensures the ideal ratio between fibers and resin (not too much, to avoid excessive weight and ensure a perfect bond between the layers, and not too little, to avoid dry spots that can lead to breakage) even before it is further processed by our factory.
For these reasons, prepreg fins are at least 50% stronger in terms of breaking strength than the standard/conventional RTM technology, which uses dry fibers with "uncontrolled" resin addition.

Advantages:
- Flex and twist are not only determined by the length, width, and profile thickness of the fin design (as with G10 fins), but can also be adjusted by the arrangement of the prepreg layers.
- Lighter than G10.

Disadvantages:
- Not as easy to repair damages caused by ground contact.
- The most expensive way to manufacture a fin.

Best suited for:
Prepreg fins are ideal for longer high-performance fins from freeride up to racing.

PRODUCT DETAILS

Meet the brand‑new F_STYLE fin — the ultimate weapon for pure new‑school freestyle progression. Designed by Dani Aeberli, and backed by more than 20 years of experience working alongside the world’s best freestylers, this fin represents the evolution of modern freestyle performance.

Dani was among the first to pioneer wider fin concepts, making today’s super‑short shapes possible — shapes that have now become the benchmark for hardcore freestyle riding.

The F_STYLE features a refined, thicker profile that delivers explosive acceleration and strong counter‑pressure, giving you the maximum pop you need to launch higher into your biggest moves.

Premium materials. CNC precision.

The F_STYLE is CNC‑milled with absolute precision from black G10, an ultra‑dense, prepreg‑laminated fiberglass block. This makes G10 the ideal material for medium‑sized, maneuver‑oriented center fins, delivering exceptional stiffness, control, and long‑lasting durability.

Its ZERO FLEX & TWIST construction guarantees instant release and unmatched freedom during slides, allowing you to flow through massive combos — from doubles to triples — with total smoothness and control.

No matter which board you ride, the F_STYLE will elevate your freestyle game and unlock the next level of your performance.

TECH AND SHAPE FEATURES

TechFeature

AI_Fin_3D

Our software is based on math data-driven input. Apart from being much more accurate and faster, complex 3D design tasks such as the perfect profile transition in the crucial tip area, where the fin sweeps backward, would otherwise have been impossible to realize.

This allows us to cross-check the outcome using artificial intelligence to ensure maximum precision. This is the key secret behind the outstanding efficiency of our fins.

Super Low Aspect Design

The extra-wide design allows us to shorten the fin length as much as possible without losing surface area. This shortest possible length is the base for all air and spin moves.

ZERO FLEX & TWIST DESIGN

The ZERO FLEX & TWIST DESIGN guarantees maximum release to let you slide smoother through massive double or triple moves. 

PROFILE DESIGN

The thicker refined profile results in explosive acceleration and great counter-pressure to enable maximum pop to send you flying higher. 

Black G10

G10 is an extremely compressed block of prepreg laminated fiberglass sheets. This block is placed in a CNC milling machine to create the final shape and profile.

Advantages:

> Due to its high-compression G10 is extremely durable.

> Easy to sand, allowing to repair damages caused by ground contact.

Best suited for:

G10 is the ideal choice for medium-size maneuver center fins.
