FULL DESCRIPTION
Our most successful 5-batten sail ever came back with a bang in SS23, and for SS25 we have given it a facelift!
The DUKE combines our LIGHT DONE RIGHT construction and all the other build concepts developed over the past decade to set a new benchmark for wind-range oriented handling sails.
When it came to developing the DUKE, it was a 1.5 year project, with you, the final user always at the center of the development. As a starting point we involved “real” end-consumers who use these kinds of sails regularly and our surf centers to define a bucket list for the reincarnation of the DUKE, and here is the outcome and how we went about it:
Maximum wind range especially in changing and/or super gusty conditions.
This is the most important factor and the major advantage when going for a 5-batten handling sail. As a simple rule, more battens give you more control and a bigger wind range. Usually this has a negative effect on the low
end power as more battens make it harder for the wind to inflate the sail and it becomes less efficient for pumping. Therefore, we have incorporated the BATTEN FREE CENTER concept from the SUPER_HERO. Instead of the usual even batten distribution the DUKE features a bigger gap between the foot batten and the batten above the boom. This makes the boom area easier to inflate plus increases the stability in the top (due to the increased batten density in this area). The second downside is that every batten increases the weight of the sail. That’s the reason why there was a trend towards fewer battens for wave sails in the past years.
Superlight feeling in your hands but without falling apart after 1-2 seasons.
The reduced weight of 4-batten sails was the major reason for the disappearance of the 5-batten sails in the past decade. Fortunately, we have made some major construction improvements over the last 10 years. The outcome of this development was the LIGHT DONE RIGHT CONSTRUCTION which got introduced in 2022. By replacing the usual multilayer reinforcements with a single layer of high-quality fabric and introducing the ONE PIECE SLEEVE we were able to reduce the overall weight by 300g. Most important we are the only brand out there where these weight savings have been achieved without reducing the thickness of the film and XPly panels. Only this way we can still guarantee our unmatched 5 year warranty. Another issue when reducing the film thickness is that the sail becomes spongy as the energy fizzles out in the increased elongation. This leads to the sail feeling heavier in your hands. So in contrary to others our sails are not just lighter on the scale but especially in your hands on the water when you use them. Cause this is where it really counts!
Early planing power even without excessive pumping
To achieve maximum planing power the DUKE features a high draft distribution combined with a deep profile which helps lifting the board onto the plane.
Super neutral in maneuvers
To make tricks and turns as easy as possible the sail should go completely neutral during maneuvers. Therefore, the DUKE comes with a more forward oriented draft position. The forward draft turns the power off and goes completely neutral as soon as you sheet out or shift the sail. This results in a much higher success rate.
Good lift and control for jumping
The higher draft position also increases your airtime as it generates lift while the more forward oriented draft position helps you to always remain in control.
Maximum range of use
One of the greatest assets of the DUKE is its versatility. It’s pure extasy in bump & jump conditions on your freewave board or as a smaller sail for blasting around on your freeride board. The forward/up draft position makes it also very capable for classic and even new school freestyle tricks. And last but not least it’s a great sail for medium wave and/or jumping conditions especially in gusty or challenging wind conditions. So, the new DUKE is a real all- round high performance contender challenging any handling sail out there.
Straight forward and fast to rig
With all the features, markers and hints we have developed over the past 40 years it’s safe to say that there is no other sail which is faster or more precise to rig than a DUOTONE sail. This means even if you aren’t a pro who is rigging and trimming their sail every day you will still achieve the same correct trim. As only with the correct trim can you unlock 100% of the sail’s performance.
Similar feeling than your bigger Freeride/Performance sails
Another important factor is that all the sails in your quiver should have a similar feeling/behavior. This even counts for professionals as it usually takes even them a full day to get used and adjust their style to a sail which feels very different. The major reason why sails feel different is the position of the draft in the sail. Fortunately, also here the DUKE has got you covered as it features a very similar draft position to the vast majority of all modern freeride sails.
So, you see we have thrown our entire know-how and experience into the mix to create the most sophisticated Jump N’ Ride high performance sail ever.

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.
