2027 Duotone Cosmic (4) D/Lab Customized

FOCUS GROUND SWELL >< WINDY EURO WAVES (NOT FOR ONSHORE)

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.

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.

MADE FOR THE FEW - MADE FOR YOU!

FULL CUSTOM D/LAB TECHNOLOGY
CNC shaped using our most high-end layup and entirely handcrafted, identical to high-end custom made boards for an unmatched weight-durability ratio.

CUSTOMIZED
Individual color schemes and a unique serial number make it your personal dream board.

PROVEN & TESTED SHAPES
Proven and tested shapes from the brand with the longest experience in windsurf board design. Just one millimeter or a mismatched fin/mast-track position can turn a magic board into an under-performer. This way, you or a potential second-hand customer know exactly what you are getting.

MADE TO ORDER
All D/LAB CUSTOMIZED boards are made to order. Your board will be scheduled for production AFTER you place your order and will be produced EXCLUSIVELY for you. Therefore, delivery can take up to 18 weeks (depending on when we get a production slot for your board). 

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.
