New Duotone Composite Paddleboards: Cosmic, Flow and Raven Hard SUP Range

The new Duotone composite paddleboard range has arrived at The SUP Company, and it is a really interesting step for paddlers who want more feel, more glide and more direct performance than an inflatable SUP can normally offer.

This is not one board trying to do everything. Duotone has split the range into three clear families: Cosmic for SUP surf, Flow for relaxed all-round hard-board paddling and small waves, and Raven for faster touring, fitness and distance paddling.

If you already know you want a hard paddleboard, you can browse the full composite paddleboard range at The SUP Company. If you are still weighing up inflatable convenience against hard-board performance, this guide will help you understand where each new Duotone model fits.

Why this Duotone hard SUP range matters

Duotone has a strong background across performance watersports, and this new composite SUP range feels properly thought through. Each model has a clear role, which makes the buying decision easier.

At The SUP Company, that matters. Most customers are not just asking, “Which board looks best?” They are asking:

Will it suit my weight and ability?
Will it work in UK conditions?
Is it too specialist for what I actually do?
Should I choose the standard or Bamboo version?
Do I need a surf SUP, an all-round hardboard or a touring board?

That is where this range makes sense. The Duotone Cosmic SLS and Duotone Cosmic are for wave-focused paddlers. The Duotone Flow and Duotone Flow Bamboo are for paddlers who want a smoother hard-board feel across flat water and small waves. The Duotone Raven and Duotone Raven Bamboo are for distance, touring and fitness paddling.

What is a composite paddleboard?

A composite paddleboard, often called a hard SUP, is a rigid board built around a shaped foam core with composite layers around it. Compared with an inflatable SUP, a good hard board normally feels more direct underfoot, glides more cleanly and responds more quickly when you paddle, trim or turn.

The trade-off is practicality. A hard SUP needs storage space, careful transport and usually roof bars or a van. If you need a board that packs into a bag, an inflatable paddleboard will still be the easier choice.

Choose a composite board if performance, feel and glide matter more than storage convenience. For a deeper comparison, read our iSUP vs hard boards guide.

Duotone Cosmic SLS: the premium SUP surf option

The Duotone Cosmic SLS is the higher-performance surf SUP in the range. It is aimed at paddlers who want a wave-focused hardboard with speed, drive and the ability to tune the fin setup to suit different conditions.

Choose the Cosmic SLS if you are already confident on a paddleboard and want to move into more committed SUP surfing. It is not the board for flat-water cruising or relaxed family paddling. It is built for waves.

The big difference versus the standard Cosmic is the construction and fin system. The Cosmic SLS uses Duotone’s Full Custom SLS construction and a 4+1 fin box layout, giving you options for thruster, quad, twin or twin-plus-trailer setups. In plain English, that means more tuning potential as your surfing improves.

Best for: committed SUP surfers, improving wave riders, experienced paddlers and anyone wanting one serious surf SUP for varied UK wave conditions.

Duotone Cosmic: proper wave SUP performance with a more accessible feel

The Duotone Cosmic sits below the Cosmic SLS and will be the better choice for many paddlers moving into dedicated SUP surf boards.

It keeps the wave-focused shape, but uses a more accessible Custom CNC construction and a simpler fin setup. That makes it a strong option for improving riders who want a proper hard SUP for surf without jumping straight into the most technical version.

For UK conditions, this is important. Our surf is often softer, wind-affected and inconsistent, so a board that helps you get into waves cleanly and gives you a stable platform can be more useful than something ultra-specialist.

Best for: intermediate paddlers moving down from a larger all-round board, SUP surfers wanting a dependable everyday wave board, and larger paddlers choosing one of the more stable sizes.

Duotone Flow: the hard-board upgrade for cruising, small waves and progression

The Duotone Flow is the board many inflatable paddlers should look at first if they are curious about moving into a hard SUP.

It is inspired by a classic Malibu longboard outline, so it has a smooth, easy-going character rather than a short, aggressive surf shape. The rounded nose helps with early glide and wave entry, while the fuller mid-section gives confidence underfoot.

This makes the Flow a sensible board for mixed UK paddling: flat water, sheltered coastal cruising, gentle chop and small waves. It gives you the connected hard-board feel without making every session feel like a balance test.

The Flow comes in three sizes: 10'0 x 29, 10'0 x 30 and 10'6 x 31. As a simple guide, lighter and more confident paddlers can look at the 10'0 x 29, while the 10'6 x 31 is the most confidence-building option for heavier riders or newer hard-board users.

Best for: paddlers upgrading from an inflatable SUP, relaxed coastal paddling, small-wave fun and all-round hard-board progression.

Duotone Flow Bamboo: the premium Flow with more response

The Duotone Flow Bamboo uses the same general shape concept as the standard Flow, but upgrades the construction to Duotone’s Full Custom Bamboo layup.

The practical difference is feel. The Flow Bamboo should feel stiffer, livelier and more direct underfoot. That is worthwhile if you value feedback through the board, want better paddle response and expect to use the board regularly enough to appreciate the upgrade.

Choose the Flow Bamboo if you like the idea of one premium hard SUP for relaxed flat-water paddling, coastal cruising and longboard-style small-wave surfing.

Choose the standard Flow if you want the same easy-going shape at a more accessible price point.

Best for: improving paddlers who want a premium hard-board feel, regular small-wave riders, and customers who want the Flow shape in its most refined version.

Duotone Raven: fast touring without going too narrow

The Duotone Raven is the distance and touring model in the new hardboard range. At 12'6 x 28.5, it gives you a longer waterline and better glide than a typical 10'6 all-round board, without pushing you into a narrow race board that demands constant concentration.

This is a strong upgrade for paddlers who have outgrown a general all-round SUP and now want to cover more distance, paddle straighter and feel more efficient on rivers, lakes, canals, estuaries and flatter coastal water.

The standard Raven uses Duotone’s Custom CNC construction, making it the more accessible option compared with the Raven Bamboo. It still gives you the key hard-board benefits: no inflation, no soft flex underfoot and a cleaner response from each paddle stroke.

Best for: touring paddlers, fitness paddlers, confident improvers and anyone wanting a faster hard SUP without going full race.

Shop the Duotone Raven or compare more touring paddleboards.

Duotone Raven Bamboo: the premium fast touring board

The Duotone Raven Bamboo is the premium version of the Raven touring shape. It keeps the same 12'6 x 28.5 touring platform, but uses Full Custom Bamboo construction for a stiffer, livelier and more refined feel.

If you paddle regularly, enjoy longer routes and want a hard touring board that rewards good technique, the Raven Bamboo is the one to look at first. It has the glide and direction-holding you want for distance paddling, but the 28.5 width keeps it more realistic for everyday use than a narrow race board.

It also includes a tour-ready deck layout with bungee storage, making it useful for dry bags, hydration, a spare layer or light adventure kit.

Best for: regular touring paddlers, fitness paddlers, committed distance paddlers and anyone wanting the best-feeling Raven construction.

Do not forget the paddle, leash, bag and rail tape

Most composite boards are not complete “everything included” packages in the same way many inflatable SUPs are. Before ordering, check exactly what is included with the board and what needs adding.

For most hard SUP setups, we would look at:

A suitable SUP paddle, ideally lighter and stiffer if you are buying a premium board.
A correct leash from our SUP leash collection, chosen for flat water, touring or surf use.
A protective composite board bag for storage and transport.
SUP rail tape to help protect the rails from paddle marks.
Suitable SUP transport accessories if you are carrying the board on roof bars.

If you are buying a Cosmic for waves, a suitable surf leash and board bag are important. If you are buying a Raven for distance, a lightweight carbon or carbon-blend paddle will make a big difference over longer routes.

Try before you buy and get specialist advice

Hard boards are worth choosing carefully. Size, width, volume and construction all affect how the board feels, and the right choice depends on your weight, balance, experience, storage, transport and where you paddle.

That is why The SUP Company is not just an online listing. We are a specialist watersports retailer with real shops, real paddling experience and the Woodmill SUP Test Centre in Southampton, where customers can compare boards and paddles on sheltered water where suitable.

If you are unsure whether you need the Cosmic, Flow or Raven, speak to us before ordering. We would rather help you choose correctly first time than see you end up with a board that is too narrow, too specialist or not practical for your storage and transport.

Finance and delivery

Composite paddleboards are considered purchases, especially once you add a paddle, leash, board bag and transport kit. Finance options are available on qualifying orders, which can be useful when investing in a complete setup.

Hard boards also need careful delivery handling. Delivery charges, options and lead times can vary by product, size and destination, so please check the product page and checkout carefully or contact the team if timing matters.

Frequently asked questions

Are Duotone composite paddleboards better than inflatable paddleboards?

They are better for feel, glide, response and surf performance, but not automatically better for every paddler. Inflatable paddleboards are easier to store, transport and travel with. Choose a Duotone composite SUP if performance matters more than pack-down convenience.

Which Duotone hard SUP is best for surfing?

The Duotone Cosmic SLS is the highest-performance surf SUP in this range, while the Duotone Cosmic is the more accessible wave-focused option. Choose the Cosmic SLS if you want lighter construction and more fin setup options. Choose the Cosmic if you want a proper surf SUP with a more forgiving everyday feel.

What is the difference between Duotone Flow and Duotone Flow Bamboo?

The shape and use are very similar, but the construction is different. The Duotone Flow uses Custom CNC construction, while the Flow Bamboo uses Full Custom Bamboo construction for a stiffer, livelier and more premium feel on the water.

What is the difference between Duotone Raven and Duotone Raven Bamboo?

The Raven and Raven Bamboo share the same fast touring purpose, but the Raven Bamboo uses Duotone’s more premium Full Custom Bamboo construction. Choose the standard Raven for better value and the Raven Bamboo for a more refined, responsive touring feel.

Which Duotone composite SUP is best for distance paddling?

The Duotone Raven and Raven Bamboo are the distance and touring boards in the range. Both are 12'6 x 28.5, giving better glide and tracking than a shorter all-round board while staying more manageable than a narrow race SUP.

Can beginners use these Duotone composite paddleboards?

Some confident beginners may suit the larger Flow or Raven sizes, but complete beginners will often be better starting on a wider all-round inflatable board. Hard boards are more rewarding once you have the storage, transport and basic paddling confidence sorted.

Can I try a Duotone composite paddleboard before buying?

Where suitable and subject to availability, The SUP Company can help customers compare boards and paddles through the Woodmill SUP Test Centre in Southampton. If you are unsure which model or size is right, contact the team before booking or ordering.

Do Duotone hard paddleboards include a paddle?

Most hard boards are supplied as board-and-fin setups rather than complete inflatable-style packages. Always check the product page carefully. In most cases you will also need a paddle, leash, board bag and transport protection.

Should I choose a surf SUP, Flow-style hard SUP or Raven touring SUP?

Choose Cosmic if your main focus is waves. Choose Flow if you want flat-water cruising, small waves and an easy hard-board upgrade from an inflatable. Choose Raven if you want better speed, glide and distance performance for touring or fitness paddling.
