Duotone Fin F_Wave Single (Power)

Duotone introducing the brand‑new F_WAVE SINGLE fin — the ultimate choice for riders seeking top performance on single‑fin freewave boards or traditional wave boards. Designed by Dani Aeberli and backed by over 20 years of expertise. The F_WAVE SINGLE delivers true all‑around performance for any (free)wave‑oriented conditions. It’s the fin that truly does it all: the smaller sizes feature a more wave‑oriented outline, while the larger sizes transition into a fast and versatile freewave shape. Every detail of the F_WAVE SINGLE is engineered for performance. Premium materials. CNC precision. The F_WAVE SINGLE 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 stiffnessmaximum controllong‑lasting durability Its straighter leading edge along the first 10–12 cm of the base ensures explosive acceleration, early planing, and impressive top‑end speed. Toward the tip, the fin’s profile has been carefully modified to increase flex — even with the extremely stiff Black G10 construction. Combined with its unique hydrodynamic profile, this provides outstanding manoeuvrability, precise handling, and excellent grip in all situations. The result is a fin with an exceptionally well‑balanced character, offering the ideal mix of manoeuvrability, control, upwind performance, and speed. The F_WAVE SINGLE is engineered to elevate every session — no matter the conditions.

This Duotone fin is designed for precise control, grip, and reliable performance in demanding windsurfing conditions.

Tech Features

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.
BASE DESIGN: Wide and stiff fin base for direct power transmission.
MAX EFFICIENCY DESIGN: 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. In accordance with the water flow, the fin width transitions from super narrow to maximum cord width exactly where the fin sweeps backward. Creating a perfectly smooth transition to maintain the maximum thickness of the profile at 30% of the fin width is THE key secret behind the outstanding efficiency of our fins.
TWIST DESIGN: Medium twist for balanced behavior between manoeuvrability, control, upwind performance and speed.
FLEX DESIGN: Medium flex tip for balanced behavior between manoeuvrability, control, upwind performance and speed.
Prepreg: 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. Best suited for:Prepreg fins are ideal for longer high-performance fins from freeride up to racing.
OUTLINE DESIGN: Strongly curved leading edge for maximum manoeuvrability.
OUTLINE DESIGN: Medium curved leading edge for balanced behavior between manoeuvrability, control, upwind performance and speed.
