The Easy-Going All-Round shredder

This board takes the guesswork out of paddling and wave catching, making it easier than ever to enjoy a smooth, flowing ride—even in tricky conditions.

Perfect For:

Beginner to intermediate surfers

Easy wave-catching

All-day beach sessions

FULL DESCRIPTION

If you’ve struggled with paddleboards that feel clunky or hard to steer, the Mid-Length SUP was made with you in mind. It’s been carefully designed to track straighter, so you’re not constantly switching paddle sides, and it catches waves more easily—making it perfect for anyone looking to improve their surf game or just have more fun.

The twin-fin setup with specially designed fins helps the board stay balanced and responsive, while the swallow tail and sleek nose give you just the right mix of stability and maneuverability. The double concave bottom adds lift and makes it easier to move from rail to rail, which translates into smoother, more flowing turns—even at lower speeds. It’s a go-to choice for relaxed beach days, soft rolling waves, and anyone who wants an easy, enjoyable ride.

Kai Lenny & his Sup Collection by Quatro. A new era begins.

Two movements took shape on Maui’s North Shore in the early ’90s. Kai Lenny — destined to become the most versatile waterman on the planet. Forward Maui — the creative force behind Quatro and KT Surfing.

A Shared Vision.

From towing into monster waves, riding remote reef breaks, competing internationally, traveling and exploring all the waves this world has to offer then back to spending hours tweaking designs and shaping in the factory – Kai and Keith have forged a shared pursuit: to transcend boundaries in Surfing, Tow-in, Windsurfing, Sup, Kiting and Foiling. The result is relentless innovation – driving the future of board design.

Kai started surfing at 4, windsurfing at 6, Sup at 7, and foiling / tow-in by 9. He’s spent a lifetime redefining what’s possible across every discipline.

Kai Lenny: “Since 2019, Keith has shaped every board on the face of the planet under my feet. All these sports feed into each other. The more time I spend on the water, no matter the medium, the better I get — and the more fun I have.”

Since 1994, Keith Teboul has been pioneering construction and shaping from his home in Haiku, Maui, the ground zero for global wave and wind innovation. The legendary shaper of Quatro and KT, translates Kai’s unfiltered feedback into ever-evolving custom boards, spanning everything from Jaws, Mavericks, and Nazare to Ho’okipa, Indo, and the North Shore of Oahu. Now, that synergy is opening its doors.

The Kai Lenny Vault. Sup Collection.

Since his early SUP days, Kai has been pushing the limits of Sup wave riding. Constantly channeling his innovative vision and style on the water into the board quiver that he rides. Kai has become one of the most decorated athletes in Sup history, having won multiple major championships. He has won at least 8x Sup world titles which include victories in both racing and wave disciplines, not to mention the legendary Molokai 2 Oahu long distance Sup World Championship. Each model channels Kai’s one-of-a-kind riding style — sharpened from grom to big-wave icon — with refined outlines, advanced materials, and a multi-discipline mindset. His signature approach translates into this signature collection. This three model lineup, is ready to blow your mind. Covering all your needs from performance wave riding through to long board cruising.

Wing Foiling Gear

I cannot sing enough praises for H2O Sports! I have over the years made small purchases because they’ve been the most competitive online but recently I bought some new wing foiling kit and there was some slight damage to the alloy mast - well H2O’s aftercare was second to none!! They were instantly chasing down a replacement part and happy for me to be using the old part (albeit a bit bent) whilst waiting for the replacement. So refreshing to experience such great customer service.
Many many Thanks! - will be ordering more and more from this company!!!

Great buying experience. Great prices and delivered quickly. Thanks Guys.

Duotone Unit SLS 2025

After 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

Duotone Carve DLAB and Unit SLS wing

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!

Light wind lift

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 🤙

The best in the business.......

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!

Duotone slim 2.0 Dlab 2.0 carbon mast

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.

Foil Mast Slim 2.0 D/LAB
Duotone Float 5 m is a summer light wind weapon

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.

Duotone sky surf/sky style, Duotone unit, Dlab foil range.

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.

New to downwind boards and loving it!

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).

Graham Lockyer
Downwinder SLS Wing Board
Enhanced low-end power, stability, and maneuverability at a great price

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.

Graham Lockyer
Unit SLS Concept Blue Wing
Great board for all conditions

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.

Graham Lockyer
Sky Style SLS Wing Board
Great performance at an attractive price

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.
