BRAND-NEW AND UNIQUE
THE INTRODUCTION OF THE D/LAB BOARDS IN 2024 MARKED THE DAWN OF A NEW ERA. NOW, IN 2026, WE ARE EXCITED TO PRESENT THE BIGGEST UPDATE IN OUR BOARD HISTORY EVER. APART FROM ALL NEW SHAPES, NO STONE WAS LEFT UNTURNED AND WE ARE PROUD TO PRESENT YOU SOME UNPRECEDENTED AND TRULY UNIQUE FEATURES, PROCESSES AND TECHNOLOGIES.
360° R&D
With designer Kai Hopf and our product managers Dani Aeberli and Marco Lang, one and the same team is now responsible for the board, rig and even fin development. This results in an unrivalled board-rig ecosystem in which all DUOTONE products are really matching 100% now.
Besides this perfect match, the other driving force behind our R&D is the relentless push of our wave team around Victor Fernandez and Liam Dunkerbeck for better and better products.
WORLD WIDE WAVE RIDE - DEVELOPED AND TESTED ON MAUI AND EUROPE
From storm-chasing the rugged reef breaks of Ireland to the ground swell of Brittany, Canarias high wind spots, the endless point breaks of Cape Verde, and the powerful beach breaks of Klitmøller and Cape Town, all our wave boards have been tested at these spots. And, of course, they have been pushed to the limits on the legendary North Shore of Maui - truly the ultimate proving ground for any down-the-line board.
SUPERIOR TECHNOLOGY
Unlike the industry-standard semi custom technology, all our boards are now produced in a full custom technology which results in the best weight vs. strength ratio.
AI_BOARD_3D DESIGN SOFTWARE
In contrast to the industry-standard Shape3d program, our own exclusive 3D CAD software is based on math data-driven input. This allows us to cross-check the outcome using artificial intelligence to ensure maximum precision. Apart from being much more accurate and faster, complex 3D design tasks such as our ground-breaking SYNCED CURVES CONCEPT would otherwise have been simply impossible to realize.
CNC SHAPED ONLY
All our boards are CNC shaped now which is not only much more accurate, but opens more decisive advantages compared to the traditional mould construction method which allows us to implement new shapes at any time.
PRODUCTION FOCUSED DEVELOPMENT
Every single prototype is made in our exclusive factory using the exact same process and materials as the production boards. This way, each prototype has exactly the same weight and flex and therefore feels identical to the board you get.
PRODUCT DETAILS
YOU LOVE THE DRIVE AND GRIP OF A QUAD – BUT NOT THE LOCKED-IN, DRAWN-OUT TURNS MOST QUADS GIVE YOU. YOU WANT A BOARD THAT FLOATS THROUGH WHITE WATER LIKE ONE 5 LITERS BIGGER AND CARVES LIKE ONE 5 LITERS SMALLER. AND YOU WANT EXACTLY WHAT THE TEAM RIDES – NOT A CUSTOM LOTTERY. THEN THE COSMIC (4) D/LAB IS YOUR WEAPON OF CHOICE!
The Cosmic (4) D/LAB is Duotone's World Cup wave board for advanced to expert riders chasing ground swell and windy Euro waves from Maui to Cape Town, Brittany to Mauritius. Built as a quad fin wave board in FULL CUSTOM Production technology, it is Made-To-Order with custom-fins included, in sizes 53 to 106 liters.
FULL CUSTOM Production is the foundation. Every prototype is made in the factory under identical material conditions. What the team rides is exactly what you get: consistent, reproducible, with full control over weight and layup at every stage.
The SYNCED CURVES CONCEPT is the architectural core. Using Duotone's AI_BOARD_3D software, rocker, outline, and rail curvature are synchronized across three zones. Around the mast track, more curvature draws you into the bottom turn. Behind the back strap, the curves tighten again for an explosive top turn. The Cosmic (4) D/LAB transitions between bottom- and top turns without hesitation.
The 3-STAGE ROCKER divides this wave board into three zones. A flat mid section gives a stable platform when switching between bottom- and top turn. The nose rocker engages the rail on front-foot drive. The KICKSTARTER TAIL delivers a progressive tail-kick for precise water release, back-foot acceleration, and tight top turns. The STABLE YET RADICAL CONCEPT adds 1–2 cm of width and more outline curvature. With that the Cosmic (4) D/LAB floats through white water like a board 5 liters bigger and carves like one 5 liters smaller.
For 2027, every detail is refined. New asymmetric side fins deliver even more drive and grip. A refined layup brings the board weight down by another 100 to 200 g depending on board length. More nose rocker helps you cross even gnarly white water. The refined tail outline sharpens turn-ability and grip. The refined tuck line in the mid-front section improves acceleration and control from entry to exit.
Quad setup: ideal for side and side-off conditions and strong current. Not for onshore conditions.
Target rider: advanced to expert wave-rider
Best for: ground swell to windy Euro waves, side and side-off conditions
Key features:
> New asymmetric side fins for even more drive and grip
> Refined layup reduces weight by 100–200 g depending on board length
> More nose rocker for clean crossings even through gnarly white water
> Refined tail outline for sharper turn-ability and grip
> Refined tuck line in the mid-front section for improved acceleration and control
QUAD GRIP WITH TOP-TURN SNAP. MADE TO ORDER FROM 53 TO 106 LITERS, MATCHING CUSTOM-FINS INCLUDED. NO TUNING LOTTERY – JUST YOUR BOARD FOR YOUR WAVES.
SEE WHAT'S RIGHT FOR YOU
ROCKER LINE
From the straps back, the GRIP and COSMIC have very similar rockers with a (rail) tail-kick at the last 4-5cm from the tail.
> Allows both boards to perform super tight top turns.
GRIP
In the mid section between the mast-track and the nose, the GRIP has slightly less nose rocker.
> The lower front two-thirds of the GRIP allows the board to plain up earlier and at a tighter angle to the wind.
> It will also keep its momentum better at lower speeds, more drawn out turns and rounder/flatter/ less powerful waves.
> On the wave this lower front section puts you in a more upright position, making it much easier to engage the front foot during bottom turns.
COSMIC
Features a higher rocker in front of the straps and at the nose.
> The board needs more power to maintain its speed. Therefore it requires a more powerful wave and/or wind.
> In marginal conditions, you will end up having to bare off the wind more to keep your speed. Therefore, it is less suitable for smaller onshore waves.
> However, on a powerful ground-swell wave, the board will push back less and tends to sink more into the wave. This gives you more control on a full rail turn and the board will want to turn harder the harder you engage it.
BOTTOM SHAPE
Both boards feature a V double-concave in the front.
> Improves riding comfort, control going out and upwind performance.
GRIP
Maintains an alternating V throughout the entire length.
> The V acts like a seesaw, making it easier to put the board onto the rail even in slower waves.
COSMIC
The bottom transforms into a flat double concave underneath the feet, followed by a mono concave towards the tail.
> Provides additional control even during high-speed rail-to-rail turns on fast ground-swell waves.
OUTLINE
GRIP
Features a wider nose-area.
> Generates more lift when deeper in the water and gives the rail more resistance when in the water, giving you more power/drive on smaller or less powerful surf.
COSMIC
Features a narrower nose outline.
> Gives you more control during the bottom turn at higher speed in bigger ground-swell waves.
TAIL SHAPE
GRIP
Features a wider tail.
> Provides better acceleration and more counter-pressure when jumping or during turns on slower waves.
COSMIC
Features a narrower tail.
> Improves control in higher ground-swell waves.

QUAD SETUP
Ideal for side/side-off and/or strong current as it gives you more grip especially for lighter riders and smaller boards.
Attention: does not work well in onshore conditions since the 4 fins produce extra drag and are not ideal for slashy turns especially in slower waves.
TRI SETUP
Ideal for side/side-on conditions as it allows you to go more vertical and looser in your turns. Keep in mind in higher waves a Tri setup requires a more committed vertical riding style.

BOARD SIZE RECOMMENDATIONS
Please note that due to our new shaping concept, most of our team riders are using approx. 5 liters bigger boards than before. This improves the stability even further while the new shapes are still easier and more radical on the wave.
High wind small board: body weight (kg) + 0 >< 5 liters
Everyday main board: body weight (kg) + 5 >< 10 liters
Float & ride big board: body weight (kg) + 10 >< 15 liters
