FULL DESCRIPTION
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><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 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 (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

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, 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
COMPARISON TECHNOLOGY LEVELS
FULL CUSTOM D/LAB
(used on all D/LAB boards)
- For these boards we use our most high-tech raw materials (Carbon, Innegra/Kevlar) resulting in the lowest possible weights, crispest ride sensation and maximum dent-resistance.
FULL CUSTOM SLS
(used on all 2026 SLS boards)
- The SLS construction uses a lower Carbon content and the Innegra is replaced by our exclusive S_GLASS+. This results in a more attractive price level.
- These boards are approx. 300g heavier than the D/LAB boards.
- Due to the FULL CUSTOM CONSTRUCTION the SLS boards are stronger and lighter than comparable boards made in the usual semi-custom construction.
FULL CUSTOM PVC-WOOD
(used on ULTRA GRIP, GRIP, ULTRA FreeWave)
- Our most price attractive boards made in FULL CUSTOM CONSTRUCTION. These boards feature wood reinforcements that effectively dampen peak loads.
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.
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.

Let customers speak for us
from 127 reviewsAfter purchasing this wing earlier this year it has noticeably made tacks so much smoother and overall upgraded my riding. I bought the 3.0 and 5.0 metre and my 3.0m flies very well in both underpowered and overpowered conditions
I purchased the Unit SLS 2025 wing earlier this year and it has made tacks so much smoother and upgraded my riding. I also bought the Duotone Carve 3.0 D/LAB 2025 with the 800 front wing and once again it’s been a game changer, having a great amount of glide which works perfectly for both wingfoiling and kitefoiling!
All thanks to the H2O team that always have loads of knowledge, passion for watersports and go above and beyond!
Preferring not to throw away my (now discontinued) North Red boom which had a broken cuff, I called H2O to see if there was any way to salvage it. I spoke with Matt who was very knowledgeable and helpful but came off the phone somewhat resigned that I might not be able to get the part. However to my surprise a little while later I was blown away (with a force 5) when I got a call to tell me he’d sourced one for me. And here I am now, a week on, with all the bits I need to get back on the water; whoever said people don’t have time to help others! So the moral of this story is have a little faith and try H2O!

Ordered a 1350 Glide 2.0 to progress on to from my 1750 aero free. Being a heavier rider I've found it's now my go to foil wing, initially a bit harder to get on the foil compared to the aero free but once up it feels completely effort less! Thanks to the team for getting me sorted out 🤙
James, Matt and the H20 Team are absolute gurus of the water sports industry, friendly, helpful and knowledgable. They will always give the right advice and come up with superb deals and first class support, thanks guys for always helping me to make the right decisions over the last 20 + years!
My new mast arrived from H20. Sports and it was so worth the wait. You immediately notice how much stiffer it is compared to the v1 carbon version when riding. The foil feels more responsive and direct .It also glides longer in transition s and riding bumps.
Its well worth the upgrade in my opinion.
I bpught this wing to replacr my Unit 5.5 m wing for tje summer breezes as i never liked using big wings. This wing is really powerful in the low end and allows you to pump really efficiently to get on foil with a bit of technique.
You can size down by half a metre with this wing compared to a Unit.
Its still fast and so good iwhen you roll into a tack.
Perfect quiver would be a 3 m , 4m & a 5 m in the Float for all conditions.
Its a great price too as lower than Dlab and SLS wings but with great performance.
As one of the H2O riders I have really enjoyed the variety of kit H2O have available. Including the Duotone sky surf 35Ltr which quickly become my favourite board because of its shorter and thicker shape while being low in litres it still allows me to get it out the water in some lighter winds. However it comes into its own when the wind is strong and the waves are pumping with its incredible manoeuvrability. Paired with the Duotone units (that are light weight and precisely balanced) wave riding is a dream.
I've been one of those riders who thought one board was enough. Turns out a downwind board has opened up so many more days on the water. I cant believe how easy this beast gets going in 6 knots. I use my 8' board with the 1100 and 1595 Duotone Glide. It's like a whole new sport. Whilst I've tried paddling up, I think I'll stick to winging for now (although can't wait to try the Stash Parawing).
Lots of the benefits of the DLAB Unit but without the price tag. Strong, light, and powerful. It's been great in all conditions, handles really well when over powered. I bought the 3.5, 4.5 and 5.5 to cover all eventualities. Personally I prefer the handle option which works really well with my harness. Matt and the team really helpful in deciding on the sizing.
I absolutely love my 65L/4'9" Sky Style SLS Wing Board. I'm about 88kg and it suits me for most conditions. Easy planing, great in waves, sold for jumping. Incredibly light, especially when paired with a DLAB Carve 800 foil and mast, which makes it a great overseas travel option too. Carbon finish and colours look great (picture on website doesn't do it enough justice). Not a big fan of the front foot straps overlapping but going to put the new v-strap on which will sort this.
I usually go for the DLAB or SLS Concept Blue Units but this wing has had great reviews so thought I'd give it a try. Great power delivery and handling, really light weight but solid construction. The wing’s dihedral and tension profile give amazing flight balance so although designed for wave/downwind, I think this wind would suit all levels. Bought teh 5m for the summer but bought a 4 ready for the winter swell.
The 2025 Unit is a good allrounder fast, stiff & light wing.
I prefer to size down my Unit as they are really grunty wings.
They also have great top end aswell and the white colourway looks cool.
I have ridden the Skybrid SLS 70 litre and its a great hybrid board between a short wave freesyle board and a mid length shape.
Easy to get up though its narrower than my previous boards and does require a little more effort.
The big advantage is the early planing speed to get on foil and the glide.
Its a good allrounder in waves and flat water.
