Wasup boards are built using Shark Fusion double-layer technology, ensuring high durability and optimal rigidity. Every Wasup set includes a high-quality transport bag, a durable aluminum paddle, a high-pressure double-action pump, and a safety leash – everything you need to hit the water with confidence.

Wasup Lite boards are made with a high-quality single-layer construction, reinforced with welded rails for extended lifespan. Despite being lighter and more compact, the Lite series is crafted with the same Shark-level precision, and we proudly offer a 2-year warranty, even for these single-layer models.

The Lite package also includes a 4-piece SUP/kayak combo paddle and a detachable kayak seat, giving you the freedom to paddle standing or seated – perfect for those who want the flexibility of both SUP and kayak in one board.

🧵 What Is Dropstitch – And Why Does It Matter?

The dropstitch material used in SUP boards is first pressed and then laser-cut into shape. The tiny threads you see in cross-section images are the most critical element of the board’s structure – they connect the top and bottom layers and hold the board’s shape under pressure.

The quality of a SUP board depends largely on the density and strength of these threads. The second key component is the outer surface: either single-layer or double-layer (dual layer) material.

🧱 Dual-Layer vs. Single-Layer Construction

In the past, dual-layer construction meant applying glue manually to the first layer and then laminating a second layer on top. This created strong boards, but they often weighed up to 20 kg.

Today, this process is replaced by fusion technology: the layers are no longer glued but heat-welded together. This results in lighter, stronger, and more durable boards. Different factories use different names for their fusion process, but the core principle is the same.

Modern materials are also far more advanced, meaning that even single-layer boards can now be well-made and durable, especially for recreational use.

⚠️ Don’t Be Fooled by “Load Capacity 150 kg”

Many brands advertise “load capacity: 150 kg” – but that doesn’t mean a 130 kg paddler can stand comfortably on the board. Most of the time, that figure includes sitting or passive weight.

Instead, look for the recommended paddler weight. If the brand doesn’t provide it – that’s a red flag. Choose a more transparent and trustworthy manufacturer.

Then the first rail strip is glued to the board. Once that's done, the threads are inside. Here, of course, precision in manufacturing is very important. If you look at the cheapest boards, you will often notice some irregularities and inaccuracies along the rail. Shark uses precise manufacturing processes that are the result of years of experience. Workplaces are equipped with air extractors so that as little dust as possible flies through the air. Especially with single-layer boards, it is very important how they are made. The material is strained to the maximum and therefore a larger dust particle or a fingerprint in the place where it should hold and the board will not hold air.

Pri deskah z varjenimi robovi del z lepljenem seveda odpade. Nadomesti ga varjenje, ki poskrbi, da je rob zvarjen za vedno! Tako ima sup veliko večjo življenjsko dobo. Seveda se na sup še vedno nalepijo drugi sloj roba, EVA podloga in vse D-Rinke. Vendar za osnovno tesnjenje poskrbi varjenje!

At the same time as the rail, the valve is also installed on the board. Of course, this too can be of more or less quality. But above all, it is important that it is installed accurately.

For this purpose, the upper side is cut into the dropstitch material. This means that at the valve site, the threads of the sup are not held together. This is why you can usually see a bubble under the valve on the underside. Of course, most manufacturers stick a fin box in this place below, and the matter is therefore not noticeable. If you still manage to find and see such a bubble, let me trust you that this is normal and there is no need to panic. There is simply no other way.

🧩 What About the Side Rails?

After the board is constructed, an outer side rail (tape) is applied. This layer fully covers the first inner rail and acts as extra reinforcement. It’s also the visible outer edge of the board. On Shark-manufactured boards like Wasup, this rail is made of durable reinforced material, giving the board added stiffness and load-bearing strength.

Even Wasup Lite boards, though single-layer in construction, come with two full side rail layers – something that many budget boards skip entirely.

⚠️ Don’t Be Misled by “Dual Layer” Claims

In many catalogs, sellers advertise boards as "dual layer" when in reality only the rails have two layers, while the deck and hull remain single-layer. This is a common marketing trick.

🔍 How can you spot it?

Check the maximum pressure listed on the board:

➡️ If the board cannot hold at least 18 PSI, it's not true dual layer, regardless of what the label says.

Avoid sellers who don't specify construction details or overpromise performance based on inflated specs.

🚨 Beware of Cheap Boards with Only One Rail

Boards with just one rail layer are far more prone to damage, deformation, and early failure. They may seem like a bargain, but they often have shorter lifespans and lower performance.

Wasup boards (even Lite models) use two side rail layers to ensure long-term durability, safety, and a more rigid ride on the water.

🧼 EVA Deck Pad & Attachments – Comfort and Function in Every Detail

Once the board is fully constructed, a non-slip EVA deck pad is applied. Just like other materials, EVA comes in different thicknesses and qualities.

At Wasup, we’ve chosen a thicker and more durable EVA pad, which offers better comfort underfoot, especially for longer paddling sessions, and increased wear resistance over time.

🔗 What Are D-Rings and Why Are They Important?

D-rings are the metal loops fixed to the surface of your SUP. They allow you to attach various accessories and are crucial for versatility:

are used to install a bungee cargo net – included with Wasup boards and matched in color to the design.

is essential for attaching the safety leash.

allow you to mount a kayak seat, transforming your SUP into a seated kayak setup.

🧰 Carry Handles – More Than Just a Strap

Every SUP board has a central handle for carrying. On budget boards, this is often a thin webbing strap.

Wasup boards come with a soft, neoprene-wrapped central handle for added comfort when carrying the board solo.

On our higher-end dual-layer boards, we’ve also added a front and rear handle. These make it easier for two people to carry the board, especially useful when lifting it out of the water or transporting longer models.

At Shark, the boards are then inflated to 16psi and left for 48 hours to check if they hold air.

This is followed by a visual inspection of all glued parts and installation of an elastic cargo net.

Then the boards are deflated and put into a bag. They add all the accessories (leash, pump, repair kit...). Then everything is loaded into a shipping container and we hope that it will be with us in 2 months!
