Duotone WSB Ultra Grip (Tri) D/LAB (MTO, incl. fin) 2026

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).

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
Going beyond your imagination. Built like a high-end custom board, designed with our own AI_BOARD_3D software, which enables us to integrate unprecedented complex shaping tasks. The ULTRA GRIP D/LAB CUSTOMIZED is truly like nothing else and will take your wave riding to the next level!
Similar to what we have achieved with the SUPER_HERO D/LAB sails our goal was to create real game changers with our new wave board range.

What we had learned from the SUPER_HERO D/LAB development is that you need to work on all aspects to really make a decisive improvement.

Switching our board technology from the industry-standard semi custom technology to our exclusive FULL CUSTOM PRODUCTION marked the foundation for all the rest to come (see TECH AND SHAPE DETAILS below for details). Because this technology lifted our weight vs. strength ratio to a whole new level. And it finally allowed us to make every single prototype in the factory like we are doing with our sails since over 30 years. Because the best prototype is worth nothing if it can’t be reproduced or feels different due to different materials, processes or weight.

To achieve a similar step up in the 3D design we decided to get our own CAD program written. Compared to the industry-standard Shape3D software our AI_BOARD_3D program is much more accurate and lets us perform even super complex shaping tasks like the brand-new SYNCED CURVES CONCEPT.

DESIGN GOALS >> SHAPE DETAILS

Our main goals were to create designs which have a maximum range of use and are easier (less exhausting) plus more radical on the wave.

Basically we wanted to create a more stable platform which is great for getting going and going over the white water. But at the same time the boards should turn even more radical when going down the line, which are opposing features you usually can’t combine.

Here are the 3 major shape details our team has developed over the last 2,5 years (see TECH AND SHAPE DETAILS below for all other details):

STABLE YET RADICAL CONCEPT

Our wave boards are 1-2cm wider than most other boards.

The increased width results in a more stable platform. This makes our wave boards as stable and energy-saving as a 5 liter bigger board while drifting/floating and going over white water.
Most importantly the additional width leads to an increased outline curve. This improves the maneuverability which makes the board turn as radical as a 5 liter smaller board.
The result is an unbeatable broad range of use.

3-STAGE ROCKER

Unlike the usual continuous rocker curve, our entire shape concept is based on a segmented rocker line. This accounts for the fact that the top- and bottom turn are two entirely different maneuvers. While you initiate the bottom turn more over your front foot (depending on the size of the wave) the top turn is only sailed over the back foot. This change in posture is the biggest challenge, especially when learning to wave ride – which becomes much easier with our 3-STAGE ROCKER.

The straight rocker section in-between the front- and back straps creates a super stable sailing stance/platform so that you?re in perfect sync with your board going out or on the wave when switching between bottom- and top turn.
The nose rocker starts just in front of the front straps which helps to engage the front part of the rail when leaning forward on the bottom turn.
KICKSTARTER TAIL: The tail rocker behind the back strap remains very moderate until the last 4-5cm from the tail where it transforms into a progressive tail-kick. This tail-kick generates a perfect water release and in combination with the flat rocker line results in a kickstarter-like acceleration as soon as you push a bit with your back-foot. Plus the tail-kick obviously allows for super tight top turns when snapping back the board with your back-foot.
SYNCED CURVES CONCEPT (rocker>< windy Euro waves (not for onshore conditions) Ideal for Maui, Capetown, Brittany, Cabo Verde, Ireland, Chile, Mauritius B. GRIP Focus Euro waves >< logo-high ground swell Ideal for Klitmøller, Canarias, North Sea, Kanaha Finally, both ULTRA GRIP D/LAB and GRIP D/LAB can be ordered with a Quad or Tri fin box setup. Tri setup (GRIP all sizes, ULTRA GRIP 82 liter and up): 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. Quad setup (all sizes): 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 in onshore conditions.
