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.

default

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.

  1. 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.
  2. 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.
  3. 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><outline><rail)

Outline, rocker and rail shape are the 3 key elements that determine how a board feels and performs. In every rocker- and outline there are spots with more or less curvature. The same applies to the degree of rail curvature which changes considerably. To prevent the 3 curves from working "against" each other, the highest priority is to synchronize these curves. Means that in zones with an increased rocker curve, the outline curve is also increased plus the rails have an increased curvature and vice versa.

  • Increased outline curve, nose rocker and rail curvature around the mast track makes it easier to initiate the bottom turn (front foot initiated)
  • Increased outline curve, tail rocker and rail curvature behind the back strap for more radical top turns (back foot initiated)

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

We started testing this concept on existing boards and the improvements to each board were so overwhelming that we incorporated this design feature into all 2026 boards. 


Both ULTRA GRIP and GRIP 3 are designed as World Cup Wave boards to satisfy the best of the best on all kind of conditions and spots around the globe. Here are the differences:

A. ULTRA GRIP

Focus ground swell >< windy Euro waves

Ideal for Maui, Capetown, Brittany, Cabo Verde, Ireland, Chile, Mauritius 

B. GRIP 3

Focus Euro waves >< logo-high ground swell

Ideal for Klitmøller, Canarias, North Sea, Kanaha


Finally the ULTRA GRIP D/LAB CUSTOMIZED can be ordered with a Quad or Tri fin box setup.

  1. Tri setup (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.
  2. 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.


YOUR NEW ULTRA GRIP D/LAB CUSTOMIZED DREAM MACHINES ARE READY AND WAITING FOR YOU TO GO BEYOND IMAGINATION!

TECH AND SHAPE FEATURES

TechFeature

FULL CUSTOM D/LAB TECHNOLOGY

The FULL CUSTOM D/LAB TECHNOLOGY is a full custom technology which is one hundred percent identical to high-end custom made boards.

Instead of using a mould to bring the EPS foam core into its final shape each EPS block gets CNC milled. This ensures maximum precision and saves weight. 

Same as with high-end custom board makers the major advantage lays in the processing. We call this SINGLE PROCESS TECHNOLOGY and it is the key to our industry-leading weight-strength ratio. Instead of combining working steps to save time and money every single step follows its individual process. So for example instead of joining the PVC sandwich with the EPS core in a single shot we vacuum-bag the top and bottom PVC shields with the EPS core separately. 

Also instead of using standard 3mm PVC elements for the entire board we use thicker and thinner PVC plates as well according to the stress areas which makes the board lighter yet stronger.

For all D/LAB boards we use our most sophisticated layup which consists of more than 60 individual parts and components (nearly 20% more parts than used for our FULL CUSTOM SLS TECHNOLOGY). 

On top we are using the most high-end composite materials available to-date. 

  1. All carbon fibres used are a mix of high strength and high modulus carbon qualities depending on the individual requirements of each board section. Our high modulus carbon used can also be found on high-end products like aircraft’s, Formula One cars or our Platinum SLS masts, booms and extensions. 
  2. Innegra is a high modulus Propylene with unbeatable tensile and ding resistance. It offers a similar tensile strength to Kevlar, but is significantly stiffer. In addition, Innegra is the best composite fibre to prevent dents.
  3. We use our exclusive high performance S-glass fiber with an extra high silica content which offers much higher tensile strength as well as about 10-20% greater stiffness.
  4. And finally we are using our exclusive DUOTONE SENTEX® resin impregnated with silicon nano-spheres which helps us to reduce the weight even further without sacrificing durability. 

Instead of using a similar layup on all boards we use a DISCIPLINE SPECIFIC FLEX CONSTRUCTION for all our D/LAB boards since demands on the different disciplines (wave, freestyle, freeride, racing) and conditions vary quite a lot.

  1. Racing boards are e made to offer maximum performance (instant acceleration and V-max). Therefore these boards need be as stiff as possible. To achieve this no compromise stiffness we use a super high carbon content on all FALCON D/LAB layups.
  2. On wave boards though a certain „give“ is essential since these boards are very short and might become too stiff thus uncontrollable using a full carbon layup. Therefore the GRIP D/LAB boards come with a higher Innegra and S_GLASS+ content. These high-tech composites have a much higher tensile strength avoiding breakages after high landings. To still achieve an outstanding "spring-back" characteristics which makes the board more reactive and has a tremendous effect on the acceleration we use unidirectional Carbon reinforcements in longitudinal direction. 

Last but not least even every single board size has an individual layup. That’s the final stage of individualisation in construction.

The result speaks for itself since the D/LAB boards are up to 500 grams lighter than our SLS boards and up to a full kilo lighter than other semi custom production boards. And it’s the first time that a production board can compete even with the lightest custom made boards out there. 

Yet all of this is achieved without any sacrifice in durability since we always follow our core motto LIGHT DONE RIGHT.

Mini Mast-Track

The mini mast-track reduces the weight in the critical nose area. It also reduces the risk to misplace your mast base while still providing just the right amount of length adjustment for all riding styles and sail sizes.

Tail Design

SQUASH TAIL

The squash tail is the most common tail shape among modern surf boards as it’s extremely versatile. It gives you more drive and grip for tighter bottom- and top turns. It’s at its best when surf conditions are great. Its rounded corners provide hold similar to a pin tail but with more maneuverability. The slight concave provides additional grip.

Duotone Premium Strap 2.0

High quality closed cell neoprene for maximum longevity. Only black Lycra coating guarantees maximum comfort as well as maximum durability. The strap features measurement markings to allow you to quickly set up and replicate your individual size. Board specific attachments:

> All World Cup boards come equipped with double-screw plugs to prevent any twist and ensuring the most direct connection to the board

> All other boards come equipped with single-screw plugs to allow a faster repositioning of the straps plus a more comfortable ride due to a certain "give"

NEW - Completely revised and unique design:

+ 20% less weight

+ Significantly reduced elongation for direct connection and to avoid slipping in too far with risk of injury

+ Improved preforming for quick and easy assembly

Deck Shape

FLAT SPOT DECK SHAPE

The centre of the deck is completely flat, which is exactly where you stand before getting on to the plane. Similar to standing on a jetty, this provides a maximum solid platform outside the footstraps, especially in float & ride conditions. Along the footstraps, the deck transitions into a more domed shape for added control and riding comfort.

Outline

STABLE YET RADICAL CONCEPT

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

>> The increased width results in a more stable platform. This makes our wave boards as stable 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.

Rail Shape

POSITIVE RAIL CONCEPT

Instead of going for ultra thin rails our rails have a certain minimum radius/volume. This prevents the rail from burying too deep into the water and starting to blend thus loosing grip. Our POSITIVE RAILS generate a certain counter pressure (positive feedback) to be able to lean into the turn with full commitment.

HAWAIIAN TAIL RAILS (thin yet square-er than usual)

The vertical surface of the apex helps to prevent the thinner rail from digging too deeply, as it provides more lateral resistance than a rounder or knife-ier rail profile. Prevents sucking the tail down causing drag.

WAVE TUCK

We have increased the tuck line in the center and front which enables to use the entire rail for additional drive during bottom turns. Also the tuck edge got a bit softer which makes the board less nervous/bouncy when going down a choppy wave.

Bottom Shape

V double-concave into flat double-concave into single-concave (front to back). 

>> In the front the V double-concave improves the riding comfort, the control going out and the upwind performance. 

>> Just before the front straps it transitions into a flat double-concave and then into a single-concave shortly after to ensure a stable riding position.

>> Towards the tail the depth of the single-concave is gradually decreasing which results in a disconnected rocker (flatter rocker line in the center with increased rocker along the rail). The flatter center rocker results in improved planing power while the increased rail rocker improves the water release and turn-ability.

Rocker Line

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.

1) 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.

2) 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.

3) 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.


Duotone Pro Pads

8-10mm thick duo density EVA (depending on the board type) provides best dampening comfort and control. The higher-density outer layer features our signature heat pressed diamond groove pattern that protects the EVA against abrasion and provides maximum grip level and connection to the board. We only select EVA colours which don't look dirty after use and will also resist fading after hours in the sun.

AI_Board_3D

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. 

Individual Fin-Box Setup

We are no fans of 5-box setups as it is an "ugly" compromise for several reasons:

1) The 5 boxes add approx. 200-300g of unnecessary weight making the board quite tail-heavy, which also has a negative influence on the trim of the board or how it sits in the water.

2) To cover all possible trim options, you need to use unnecessary long fin boxes adding further weight.

3) With all the different fin options plus long fin boxes, finding a working trim often turns out as a mission impossible, even for team riders.

4) To really achieve the maximum performance our tests have shown that the Quad and Tri setups require a different position and angle of the side fins.

Exclusive to the ULTRA GRIP D/LAB CUSTOMIZED you can order your board with either a Quad or Tri fin box setup.

1) Tri setup (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.

2) 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.


Plug & Shred

All our center and side fin boxes offer an adjustability of only 10 mm. This saves over 100g of weight and avoids misplacing your fins which can easily turn a magic board into an under-performer.

Extensive testing with all our team riders and "normal customers" has proven that this adjustability works for everyone.

Markings at the fin boxes as well as on the mast track, indicating PRO or CONTROL, give you a clear guideline for the correct trim.

SYNCED CURVES CONCEPT

Outline, rocker and rail shape are the 3 key elements that determine how a board feels and performs. In every rocker- and outline there are spots with more or less curvature. The same applies to the degree of rail curvature which changes considerably. To prevent the 3 curves from working "against" each other, the highest priority is to synchronize these curves.

To our knowledge this complex 3d task can only be performed by our own AI_BOARD_3D software. Testing this concept on existing boards the improvements to each board were so overwhelming that we incorporated this design feature into all 2026 boards.

TechFeature
FULL CUSTOM D/LAB TECHNOLOGY
The FULL CUSTOM D/LAB TECHNOLOGY build like the most high-end custom-made boards but with a tested and proven shape.
UNRIVALED BROAD RANGE
Revolutionary new shape concept: as stable and energy-saving as a 5 liter bigger board but yet as radical as a 5 liter smaller board on the wave.
AI_Board_3D
We use our own exclusive 3D CAD software. 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. 
Exclusive Board Production
All our boards are CNC shaped now in our exclusive factory to guarantee superior weight vs. strength ratio, quality and accuracy.
Focussed World Cup wave designs
The ULTRA GRIP is designed to work all around the globe with focus on groundswell up to windy Euro wave conditions.
Exclusive Fin Production
All our fins are produced in our exclusive factory now. Instead of using one technology for all our fins we are using 3 different technologies according to the fin length and range of use.

BOARD SIZE RECOMMENDATIONS

Please note that due to our new shaping concept, 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

FINALLY LET'S TALK FINS

THE MATCHING FIN DESIGN HAS A SIMILAR IMPORTANCE TO THE BOARD PERFORMANCE AS THE RIGHT MAST FOR THE SAIL.
THAT'S WHY WE HAVE SPENT A TREMENDOUS TIME AND EFFORT INTO SETTING UP A TRULY UNIQUE FIN RANGE.


360° R&D
We don't just buy external stock fins. Instead one and the same team is now responsible for the board and fin development. This results in a perfectly matching unit lifting the board-fin performance to the next level.


FIN SPECIFIC TECHNOLOGIES
Instead of using one technology for all our fins we are using 3 different technologies according to the fin length and range of use:

- PREPREG FOR ALL LONGER FINS >> lighter than G10 and with adjustable flex due to the moulding process. 50% stronger than the usual RTM technology.

- G10 FOR ALL WAVE FINS >> indestructible

- INJECTION MOULDED CARBO_TECH FOR SHORT SIDE FINS >> guarantees the necessary tip-flex even on short fins.

FINALLY LET'S TALK FINS


THE 2 MOST INFLUENTIAL FIN DESIGNERS
With Dani Aeberli and Kai Hopf, the two Windsurfing fin designers with the most experience are responsible for our new fin range.


EXCLUSIVE PRODUCTION
Setting up our own exclusive production was inevitable to take our fin performance to the next level. Every process is supervised on site by our own QC specialist Vasin Siritho to guarantee the highest level in quality and consistency.


FOR ALL THESE REASONS, WE HIGHLY RECOMMEND TO ONLY USE THE FINS SUPPLIED WITH THE BOARD.
THIS IS THE WAY - TO UNLEASH THE BOARD'S FULL POTENTIAL!

Quote KAI HOPF (CHIEF DESIGNER)

»THE SECRET OF THE NEW ULTRA GRIP IS THAT IT IS COMPLETELY FLAT UNDERNEATH YOUR FEET IN ALL DIRECTIONS. THIS MEANS THAT EXACTLY WHERE YOU STAND, THE ROCKER LINE IS COMPLETELY STRAIGHT AND WITHOUT ANY V. THIS MAKES THESE BOARDS INCREDIBLY STABLE AND EFFORTLESS TO RIDE. ON THE OTHER HAND, OUR BOARDS HAVE MORE OUTLINE- AND (RAIL) ROCKER CURVE IN FRONT OF AND BEHIND THE STANCE AREA THAN OTHERS. THIS IMPROVES THE TURN-ABILITY DURING BOTH BOTTOM- AND TOP TURNS.«

— KAI HOPF (CHIEF DESIGNER)
Quote VICTOR FERNÁNDEZ (TRIPLE WAVE WORLD CHAMPION)

»I TESTED THE FIRST PROTOTYPE WITH THIS NEW SHAPE CONCEPT OVER 2.5 YEARS AGO. IT SOUNDS HARD TO BELIEVE, BUT THESE BOARDS ARE ACTUALLY THE REASON FOR MY 2ND SPRING IN THE PWA CIRCUIT. THE ULTRA GRIP IS SO EFFORTLESS TO RIDE AND YET SO RADICAL TO TURN AND OFFERS SUCH A HUGE RANGE. IT'S A BIT LIKE CHEATING ACTUALLY. THAT'S WHY THE ULTRA GRIP IS PROBABLY THE BEST PRODUCTION BOARD CURRENTLY AVAILABLE FOR ALL KIND OF GROUND SWELL CONDITIONS LIKE PUNTA PRETA, HOOKIPA, CHILE, MAURITIUS, BRITTANY OR IRELAND.«
