The I-SUPs are high-end boards created by Patrice Guénolé, a pioneering shaper in the world of Stand-Up Paddleboarding, and a team of passionate engineers.

It has race carrying handles and a tail pad for more control. In addition, the fin located at the rear 1/3 makes the board much more stable, more efficient with cross wind, and more maneuverable.

It’s an affordable board, inspired by the world of competition, to offer incredible glide at a record price.

With a superb design, the I-SUP Race is really a beautiful stand-up paddleboard at a record price and at the top of the range.

OUTLINE

With its long, narrow outline, this board is designed for glide. The sleek lines are optimized for paddling speed. Its pinched rounded pin tail minimizes drag and ensures smooth water release. The design maintains width underfoot for solid paddle stability, making it easy to handle. The narrow nose is made for smooth gliding, even through chop. This carefully refined shape, developed from thousands of templates over 30 years, provides unmatched performance and ease.

ROCKER

The low rocker design ensures maximum speed. When you want to pick up the pace, its sleek shape will accelerate effortlessly.

ROUNDED PIN TAIL

In racing, its glide is appreciated for its fluidity, enhanced by the narrowness of the board with this very pin tail shape. In terms of maneuverability, rounding a buoy with its tail fin is technical because it sinks easily, but it’s incredibly effective. It’s not made for surfing, but it won’t refuse a nice diagonal.

RAILS

The rails are round, as with all inflatable boards. But we’ve turned this natural shape into an advantage, allowing water to glide effortlessly over the board. No drag, just pure flow.

NOSE

The pointed nose is designed to cut through the water efficiently. It still provides buoyancy with enough width in front of the feet to maintain support during powerful paddling. In tougher conditions, its pinched shape allows for easy navigation through chop.

US Box

The I-SUP Race comes with a US Box center fin, the go-to standard for premium fins. With fins making up 50% of a board's performance, GONG has opted for this precise, versatile system in its inflatable SUPs. The outcome: a vast range of technical fins to fine-tune your board based on your skill level, goals, and the conditions you'll be riding in.

Velvet Traction Pad

Our 5mm thick Velvet Traction Pad is specially designed for even more comfort. Not only does it look great, but it also delivers exceptional grip with a velvety-soft feel! The ultra-smooth texture keeps you connected to the board, enhancing responsiveness. Get ready for long cruises and endless surf sessions without fatigue or slipping.

Adjustable Staps

I-SUPs come equipped with our ELS (Extendable Load Strap) system—adjustable, elastic, and sleek, these straps are designed to securely and effortlessly hold all your gear on board.

We’ve made the ELS system incredibly easy and intuitive to use. The elastic straps adjust smoothly—no more struggling to wedge your bag under a stiff bungee and crushing your gear in the process. Just loosen the straps, set up your equipment, and tighten them for a secure fit.

Our ELS system makes your life easier, saves you valuable time, and adds a touch of style and modernity to your board!

Carrying handles

The board features four handles for easy carrying.

A padded neoprene center handle to carry the board under your arm.
Two ergonomic silicone "turtle" handles at the front, allowing you to either pull the board by the straps or drag it through the water when exiting.
An ergonomic silicone handle at the rear, making it super easy to get the board in and out of the water, both on land and in the surf. So practical!

Travel Bag

Everything comes in a super practical and durable wheeled travel bag.

The wheels are cleverly placed on the opposite side of the carrying panel—so no pinched backside while walking and no straps getting caught under the wheels.
The backpack straps are heavily padded and extremely comfortable.
The reinforced handles are both rugged and comfortable to hold.
A spacious front pocket allows you to store your accessories and personal belongings safely.
And the compression straps minimize the bag’s volume to the bare minimum.

Double Action Pump

The included fast double-action pump is a game-changer—get on the water first without breaking a sweat:

Double action: Inflate on both the upstroke and downstroke during the initial easy phase.
Single action: As the pressure builds and pumping gets harder, switch to single action to inflate only on the downstroke. It’s way more comfortable and efficient!

Inflatable I-SUP Technology - Woven Fusion

Thanks to its high-end Woven Dropstitch Fusion inflatable technology, GONG I-SUP boards are sleek, lightweight, highly rigid, and incredibly durable.

The I-SUPs feature a double thermo-welded layer on the deck and the hull. It is this membrane that gains in lightness while maintaining the rigidity of a double layer.

The dropstitch used inside our I-SUPs is a Woven Dropstitch : it is the best assembly technique of the inflatable world, for best in class performance, rigidity and lightness.

Woven Dropstitch technology, the best compromise between weight/stiffness/strength. Combining our historical Double Layer Welded technology with the new Woven Dropstitch, this technology is by far the most reliable, lightest and stiffest.
Weight savings of around 20% compared to the classic Double Layer (no glue between the 2 welded PVC layers).
Rigidity gain of 30% compared to standard technology.
Strength gain: twice as thick as standard technology.
Double layer of PVC on the rails.
Premium Woven Dropstitch: the slightest irregularity is refused and the batch is resold to low cost factories.
High density Dropstitch Woven: with more threads per square meter than a basic Woven, it resists much higher pressures, lasts much longer, and does not present a risk of explosion.
Working pressure: 15 PSI. Our Stand Up Paddle Boards are perfectly rigid at 15 PSI. There is no need to overinflate them, but you can mount them at 20 PSI without any problem.
Two-year Warranty on all our Inflatable Boards.
We keep in stock all the elements that make up your Board because we are manufacturers. So, you can easily repair them and make them last for more than ten years. It’s as simple as repairing a bicycle wheel.

Buying guide

For whom?

This board is designed for experienced paddlers. It’s not too difficult to handle, as it comes in two widths, so you can select the one that matches your skill level.

However, we wouldn’t recommend it for beginners, as it’s still a race or long-distance cruising board.

What size for the I-SUP Race 18’?

Even though anything is possible, here we outline the main uses:

The 18’0 x 26’’ Race:

Not as challenging as you might think on flat water.
Ideal for sessions lasting over an hour on calm water.
In Downwind: It’s a bit tricky, but still manageable.
Rider weight: Doesn’t matter as long as your skill level can handle this race shape.

The 18’0 x 29’’ Race:

Quite comfortable on flat water, even for those with little experience.
Perfect for sessions lasting over an hour on calm water.
In Downwind: It’s technical, but still manageable.
Rider weight: Doesn’t matter as long as your skill level can handle this race shape.

Understanding the GONG range?

What is the difference between our First range and I-SUP range?

Best quiver choice?

This board is perfect with a Carbon Mix 100% GONG Paddle cut to the right size or adjustable, and a top of the range fiberglass or carbon fin.

What length of paddle?

The way you paddle, your stance and the frequency at which you paddle will depend on your program. You will need a longer paddle for touring for multiple hours, while you would need a shorter paddle for surfing in order to facilitate quick and strong paddle strokes to catch a wave. Take your time to pick the right length/setting for your paddle, because it will help give you the stability and performance you will need.

Examples:

For a 100% surfing session, set your paddle between your waist and +10cm.

For more relaxed surfing, a +10cm paddle will be perfect.

For a ride, set your paddle between +10 and +20cm.

Which leash?

For the I-SUP Race range, a 10’ leash is the perfect choice. Depending on your needs and style, you can opt for a classic ankle or knee leash for a mix of cruising and surfing, or a coiled leash to minimize drag for a fully racing-focused setup.

Check its condition before each session and change it every year. This is your life jacket.

Good to know :

Never leave your board in the sun, let alone an inflatable board which will heat up very quickly. You risk seeing it peel off because the materials it is made of become flexible in the heat. Never store it under a car window, or in contact with a heat source.

Never let your board get roughed up in the waves, especially when you’re close to the beach. You have to protect it from major strains. A wave that takes your board and rolls it can do damage.

Do not hold it by the leash indefinitely because it can give way under very high tension. Avoid big waves and don’t resist. If it breaks, it’s easy to change but annoying.

Stay away from oysters: this is one of the few seashells that can cut your board and sink it in seconds. Be careful +++

Don’t let your inflatable board rub on something for a long time. It can happen on a boat, for example, that your board moves with each wave and rubs for hours in the same place. The material will disintegrate because it will be as sanded. You will have a hole that will need to be covered with a patch.

Never put the board between the wave and you: risk of a broken nose type injury ;-)

Do not paddle far at sea with an offshore wind, and avoid windy outings as it is rarely fun and always dangerous. SUP is an activity that involves real risks, even in seemingly peaceful conditions. Always anticipate these risks and protect yourself.
