Description

We present the Duotone Ultra Grip D/LAB Board.

NOTE ON DELIVERY TIMES:
EVERY D/LAB CUSTOMIZED BOARD IS MADE TO ORDER. THE MAXIMUM DELIVERY TIME IS 18 WEEKS.

Going beyond your imagination. Built like a high-end custom board, designed with our own AI_BOARD_3D software, which allows us to integrate unprecedented complex shaping tasks. The ULTRA GRIP D/LAB CUSTOMIZED is truly unparalleled and will take your surfing to the next level!

Similar to our SUPER_HERO D/LAB sail, our goal with the new waveboard range was to create true game changers.

What we learned while developing the SUPER_HERO D/LAB is that you have to work on every aspect to achieve truly noticeable improvements.

The shift in our board technology from the industry-standard semi-custom technology to our exclusive FULL CUSTOM PRODUCTION laid the foundation for everything that followed (see below under TECH AND SHAPE DETAILS for details). This technology took the weight-to-sturdiness ratio to a whole new level. And it finally allowed us to manufacture every single prototype in the factory, just as we have been doing with our sails for over 30 years. After all, the best prototype is worthless if it cannot be reproduced or feels different due to variations in materials, processes, or weight.

To take a similar leap forward in 3D design, we decided to have our own CAD program developed. Compared to the industry-standard software Shape3D, our AI_BOARD_3D program is much more precise and allows us to realize even highly complex 3D shapes, such as the brand-new SYNCED CURVES CONCEPT.

DESIGN GOALS >> SHAPE DETAILS 

Our main goal was to develop designs that offer maximum versatility and are easier (less tiring) yet more radical on the wave.

Essentially, we wanted to create a more stable platform, which offers advantages especially when catching the wave and in whitewater. At the same time, the boards should also become even more radical on the wave—a combination that is usually impossible to achieve.

Here are the 3 most important shape details our team has developed over the past 2.5 years (for all other details, see below under TECH AND SHAPE DETAILS):

STABLE YET RADICAL CONCEPT

Our waveboards are 1–2 cm wider than most other boards. 

  • The greater width results in a more stable platform. This makes our waveboards as stable and energy-efficient while drifting/floating and in whitewater as a board 5 liters larger. 
  • Above all, however, the extra width results in a more pronounced outline curve. This improves maneuverability, allowing the board to turn as radically as a board 5 liters smaller. 

The result is an unbeatably wide range of applications.

3-STAGE ROCKER

Unlike the usual continuous rocker curve, our entire shape concept is based on a segmented rocker line. This takes into account the fact that top and bottom turns are two completely different maneuvers. While the bottom turn is initiated more with the front foot (depending on the wave height), the top turn is surfed solely with the back foot. This shift in stance is the biggest challenge, especially when learning the Surfing—made much easier with our 3-STAGE ROCKER.

  1. The straight rocker section between the front and rear footstraps creates a super-stable platform, so you’re perfectly in sync with your board on the wave or when riding out as you transition between bottom and top turns.
  2. The nose rocker starts right in front of the front footstraps, which helps engage the front part of the edges as soon as you lean forward during the bottom turn.
  3. KICKSTARTER TAIL: The tail rocker after the rear footstrap remains very moderate until the last 4–5 cm before the tail, where it transitions into a progressive tail kick. This tail kick ensures perfect water drainage and, in combination with the flat rocker line, provides Kickstarter-like acceleration as soon as you apply a little pressure with your rear foot. In addition, the tail kick naturally allows for super-tight top turns when you snap the board back with your rear foot.

SYNCED CURVES CONCEPT (Rocker > < Edge)

Outline, rocker, and edge shape are the three key elements that determine how a board feels and how it performs. In every rocker and outline, there are sections with more or less curvature. The same applies to the edge radius, which varies significantly. To prevent the three curves from working “against each other,” the top priority is to synchronize these curves. This means that in areas with an increased rocker curve, the outline curve is also raised and the edges have increased curvature, and vice versa.

  • Increased outline curve, nose rocker, and edge curvature around the mast track facilitate the initiation of bottom turns (initiated via the front foot)
  • Increased outline curve, tail rocker, and edge curvature after the rear footstrap for more radical top turns (initiated with the rear foot).

To the best of our knowledge, this complex 3D task can only be performed by our own AI_BOARD_3D software.

We began testing this concept on existing boards, and the improvements on each board were so overwhelming that we have integrated this design concept into all 2026 boards. 


Both the ULTRA GRIP and the GRIP 3 were developed as World Cup wave boards to meet the needs of the best of the best at all possible spots around the globe. Here are the differences:

A. ULTRA GRIP

Focus on ground swell >< windy European waves (not for onshore conditions)

Ideal for Maui, Cape Town, Brittany, Cabo Verde, Ireland, Chile, Mauritius 

B. GRIP

Focus on Euro waves >< logo-high ground swell

Ideal for Klitmøller, Canary Islands, North Sea, Kanaha


Finally, both the ULTRA GRIP D/LAB and the GRIP D/LAB can be ordered with a quad or tri fin box setup.

  • Tri-fin setup (GRIP all sizes, ULTRA GRIP 82 liters and up): ideal for side/side-on conditions, as it allows you to surf more vertically and loosely in your turns. Keep in mind that a tri-fin setup requires a more aggressive vertical riding style in high waves.
  • Quad setup (all sizes): ideal for side/side-off and/or strong currents, as it offers more grip, especially for lighter riders and smaller boards. Note: does NOT work in onshore conditions.

 

MADE FOR THE FEW - MADE FOR YOU!


FULL CUSTOM D/LAB TECHNOLOGY
CNC-shaped using our highest-quality layup and 100% handcrafted, identical to high-end custom-made boards for an unparalleled Weight-to-durability ratio.


CUSTOMIZED
A custom color selection and a unique serial number make it your very own dream board.


PROVEN & TESTED SHAPES
Proven and tested shapes from the brand with the longest history in windsurf board development. Because even a single millimeter or a fin/mast track position that doesn’t match the shape 100% can turn a magical board into an underperformer. This way, you or a potential second-hand buyer know exactly what you’re getting.


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

BRAND-NEW AND UNIQUE

THE LAUNCH OF THE D/LAB BOARDS IN 2024 WAS JUST THE BEGINNING OF A NEW ERA. 2026 MARKS THE BIGGEST UPDATE IN OUR BOARD HISTORY TO DATE. ASIDE FROM COMPLETELY NEW SHAPES, WE’VE LEFT NO STONE UNTURNED AND ARE EXCITED TO PRESENT YOU WITH 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, the same team is now responsible for developing the boards, rigs, and even the Fins. This results in an unrivaled board-rig ecosystem where all DUOTONE products are now truly 100% compatible.
In addition to this perfect match, the other driving force behind our R&D is the tireless dedication of our wave team led by Victor Fernandez and Liam Dunkerbeck to creating ever-better products.

WORLD WIDE WAVE RIDE - DEVELOPED AND TESTED ON MAUI AND IN EUROPE

From storm chasing on Ireland’s rugged reefs to the ground swell of Brittany, the high-wind spots of the Canary Islands, the endless point breaks of Cape Verde, and the powerful sandbar waves of Klitmøller and Cape Town—all our waveboards have been tested at these spots. And of course, we’ve also pushed them to their limits on Maui’s legendary North Shore—truly the The ultimate test spot for any down-the-line board.

SUPERIOR TECHNOLOGY

Instead of the industry-standard semi-custom technology, all our boards are now manufactured using our FULL CUSTOM TECHNOLOGY, resulting in the best weight-to-durability ratio.

AI_BOARD_3D DESIGN SOFTWARE

Unlike the industry-standard Shape3d program, our own exclusive 3D CAD software is based on mathematically data-driven inputs. This allows us to verify the result using artificial intelligence to ensure maximum precision. Apart from being much more accurate and faster, complex 3D design tasks such as our groundbreaking SYNCED CURVES CONCEPT would otherwise have been simply impossible to realize. 

EXCLUSIVELY CNC-SHAPED

All of our boards are now CNC-shaped, which is not only much more precise, but also offers decisive advantages over the traditional semi-custom method, allowing us to implement new shapes at any time.

PRODUCTION-ORIENTED DEVELOPMENT

Every single prototype is manufactured in our exclusive factory using the exact same process and materials as the production boards. This ensures that every prototype has exactly the same weight and flex, and therefore feels identical to the board you receive.
