Duotone Fin Race D/LAB (Tuttle)

Just like every product bearing the D/LAB label, the RACE D/LAB fin represents the pinnacle of technology and performance.

The high-end design is PWA approved yet it's not ultra technical to sail making it the ideal aftermarket upgrade for any Freerace up to World Cup Slalom board. Designed as Duotone's signature slalom fin for ultimate performance in the most demanding conditions, the RACE D/LAB delivers the lift required to keep your board perfectly balanced even in maxed-out conditions — giving you the speed and control to lead the fleet at that crucial first mark.

A balanced design was central to its development, making it equally capable when heading downwind, upwind, or through sharp turns. The construction is based on our Molded Prepreg Technology — the most advanced and most expensive fin construction available. Individually oriented carbon layers guarantee the stiffest possible base combined with a perfectly tuned tip-flex.

The RACE D/LAB features the highest carbon content and quality of all our fins resulting in the highest reflex speed for maximum performance. This is premium engineering you can feel the moment you're on the water. That construction standard enabled designer Dani Aeberli to use the thinnest profile of our entire fin range, minimising drag for maximum performance and top-end v-max.

A super-stiff base combined with a sophisticated flex pattern — carefully limited to the very tip of the fin — delivers exceptional control while keeping the fin from ever feeling nervous or overly technical to sail. The result is a fin that's genuinely accessible, even on Freerace boards. Going beyond your imagination - the RACE D/LAB sets a new performance benchmark to satisfy both competitive racers and speed-hungry amateurs.

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

Tech Features

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: Only slightly curved leading edge with a focus on speed, control, and performance. The increased curve at the tip provides a certain twist and flex for excellent manoeuvrability when jibing.
PROFILE DESIGN: Performance-oriented profile, with the max profile depth at around 34-36% (depending on the length) for maximum performance efficiency and speed over a wide wind range.
BASE DESIGN: Super stiff fin base for most direct power transmission.
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.
TWIST DESIGN: Blocked twist for increased lift, instant acceleration and max. performance.
FLEX DESIGN: Flex reduced to the very tip of the fin for instant acceleration due to reduced drag combined with maximum control to reach v-max once the gust hits in.
OUTLINE DESIGN: Very straight leading- and trailing edge for maximum speed, control, and performance.
PROFILE DESIGN: Very thin high-performance profile, with the max profile depth at around 34-36% (depending on the length) to reduce drag as much as possible for maximum performance efficiency, control and v-max over a wide wind range.
