Presentation

I-SUP boards are high-end boards created by Patrice Guénolé, a pioneering shaper in the world of Stand Up Paddle.

Derived from rigid Race shapes, the I-SUP Race 18'0 is a great long-distance racing board.

When paddling , the I-SUP Race 18'0 is the fastest in our Race range . It boasts incredible glide, allowing you to maintain a high average speed without pushing yourself too hard during long-distance competitions. Furthermore, its highly responsive nature and excellent inertia, thanks to its superior woven dropstitch fusion construction reinforced by two stringers, make it the ideal board for athletic training and racing!

It is ideal for demanding rowers who have a proven balance and good rowing technique.

Its new Ridge Traction pad provides secure support with all the comfort you need in these conditions. It also features race-style carrying handles and a tail pad for added control. Furthermore, the fin positioned at the rear third makes the board much more stable and reduces the rowing effect.

This is an affordable board, inspired by the world of competition, at a record price. This board opens the doors to ultimate riding, with all the advantages of an inflatable board: everything fits into a redesigned bag where the board and all your equipment naturally find their place!

With a superb design, the I-SUP Race is truly a very beautiful Stand Up Paddle board at a record price in the high-end category.

Outline

Its very long and narrow outline is designed for gliding . Its sleek lines are engineered to maximize paddling speed . Its rounded pin tail is very pinched to minimize drag and promote efficient water exit. This shape maintains width underfoot for secure paddling, making it very accessible. The nose is thin for smooth gliding, even in choppy conditions. This sophisticated adaptation of the thousands of templates we have developed over the past 30 years results in such efficient and user-friendly performance.

Rocker

Its low rocker allows for maximum speed . If you want to increase the pace, its streamlined shape will accelerate effortlessly.

Rounded Pin Tail

In racing, its smooth glide is a real asset, further enhanced by the board's narrow profile and pin tail shape. Maneuverability-wise, circling a buoy with its thin tail is technical because it sinks easily, but incredibly effective. It's not designed for surfing, however, but it certainly won't shy away from a good cross-country run.

Rails

The rails are round, like on all inflatable boards. But we used this natural shape to help the water glide over the board. The water doesn't stick to the rails.

Nose

The narrow nose maximizes water penetration. It maintains buoyancy with sufficient width in front of the feet to ensure support during a dynamic paddling stroke. In more challenging conditions, its almost bow-like nose allows for smooth passage through chop.

US Box

This I-SUP features a US Box center fin box, the essential standard for high-end fins. Since fins account for up to 50% of a board’s performance, GONG has chosen this precise and versatile system for its inflatable SUPs.

The result: a huge selection of high-performance fins to fine-tune your board according to your skill level, riding style, and the conditions.

Ridge Traction Pad

With its perfect grip and 5 mm thickness, the new Ridge Traction Pad delivers outstanding comfort and absolute traction. Your footing stays fully secure, giving you precise, razor-sharp control.

The contact with the board feels firm and direct for confident footing and committed paddling performance, while still maintaining the cushioning comfort of a 5 mm pad.

Adjustable Straps

Our iSUPs feature the ELS (Extendable Load Strap) system. These adjustable, elastic, and stylish straps have been specially designed to let you easily secure all your gear on board.

We designed the ELS system to be extremely simple and intuitive to use. The elastic straps are easy to adjust, so there’s no more struggling to squeeze your bag under tight bungees, sometimes unsuccessfully, and risking crushing your belongings. Simply loosen the straps, place your gear, then tighten them again to perfectly fit your load.

The ELS system makes life easier, saves you valuable time, and brings a modern, stylish touch to your board!

Carry handles

It is equipped with carry handles for easy gripping.

A central foam and neoprene handle for carrying the board under the arm.

Two ergonomic silicone “tortoise” handles in the front third that allow you to either pass the foam by pulling the board, or to get out of the water by dragging the board on the water.

An ergonomic silicone handle at the front that facilitates launching and handling the board in and out of the water. Really practical!

Transport Bag

Everything comes packed in a super practical and durable wheeled transport bag.

The wheels are positioned on the opposite side of the carrying panel, so they won’t bump against you while walking or roll over the shoulder straps.
The backpack straps are heavily padded and very comfortable.
The handles are extremely sturdy and pleasant to grip.
The front pocket has been enlarged to isolate and protect your paddle from the rest of your gear… while also leaving room for your wetsuit, poncho, spare clothes, and whatever else ;), now without any space constraints!
And the compression straps reduce the bag’s volume to the absolute minimum.

Double-Action Pump

The included high-speed double-action pump is extremely efficient, helping you be the first on the water without exhausting yourself:

Double action: air is pumped both when pushing and pulling the handle during the first stage of inflation.
Single action: during the final strokes, when inflation becomes more demanding as the board pressure increases, switch to single action mode so the pump inflates only when pushing the handle down. It’s far 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?

The shape of this board makes it ideal for experienced paddlers. Nothing insurmountable, as the shape is available in two widths, allowing you to choose the board best suited to your skill level.

However, we do not recommend it if you are a beginner because it remains a board for racing or long rides.

For what ?

Its goal is to glide as smoothly as possible, even in challenging conditions. Therefore, it is comfortable on all bodies of water and in all weather conditions.

Paddling fast, training, sporty cruising, going down beautiful downwinds, surfing small mushy waves, racing… That’s what this board loves.

What size board is needed for the I-SUP Race Flat Water 18'?

While anything is possible, we outline the main uses here:

The 18'0 x 26'' Race:

Not as technical as you might think on a flat bike.
Outings lasting well over an hour on a rather cool body of water.
Downwind sailing: it's technical but it's doable.
Build: it doesn't matter as long as your level allows you to handle this shape race.

The 18'0 x 29'' Race:

Relatively comfortable on flat ground, even with little experience.
Outings lasting well over an hour on a rather cool body of water.
Downwind sailing: it's technical but it's doable.
Build: it doesn't matter as long as your level allows you to handle this shape race.

Understanding the GONG range?

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

Which quiver?

This board goes hand in hand with a GONG Carbon Pro paddle cut to your size, and a set of high-end FCS fins in fiberglass or carbon.

What paddle length?

Your paddling technique, posture, and stroke rate all depend on your paddling style. You'll need to set your paddle quite high for a leisurely paddle trip lasting several hours. Conversely, your paddle will be set very low for surfing, as you'll need a high stroke rate to catch a wave. Take the time to properly adjust your paddle, as it's the driving force behind this activity, and this adjustment will largely determine your stability and performance.

Some examples:

A 100% surf session, adjust your paddle between your height and +10cm.

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

When paddling, adjust your paddle between +10 and +20cm.

Which leash?

Take a leash that is approximately the length of your board and at least 7mm in diameter.

Check its condition before each session and replace it annually. It's your life jacket.

Good to know:

Never leave your board in the sun, especially an inflatable one, which heats up very quickly. It could start to peel apart because the materials become brittle in the heat. Never store it under a car window or near any heat source.

Never let your board get battered by the waves, especially near the shore. You must protect it from the harshest forces. A wave that sweeps your board away and rolls it can cause damage.

Don't hold onto the leash indefinitely, as it can break under very high tension. Avoid large waves and don't resist. If it breaks, it's easy to replace but frustrating.

Stay away from oysters: they are one of the few shellfish that can cut your board and sink it in seconds. Extreme caution is advised.

Don't let your inflatable surfboard rub against anything for extended periods. For example, on a boat, your board might move with each wave and rub against the same spot for hours. The material will disintegrate because it will be sanded down. You'll end up with a hole that will need to be patched.

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

Don't paddle offshore in offshore winds, and avoid windy outings as they are rarely enjoyable and always dangerous. Stand-up paddleboarding (SUP) is an activity that carries real risks, even in seemingly calm conditions. Always anticipate these risks and protect yourself.

Equipments

Our I-SUP range is the Full Options version of the inflatable, the best there is.

It is equipped with all the high-end accessories:

An ultra-designed Ridge Traction Pad that now equips all our high-end inflatable boards.
A central handle padded with soft neoprene.
Ergonomic silicone carrying handles, either "racing" or "turtle" style.
A handle on the nose to help with carrying.
Our ELS system for attaching bags / bottles etc… very simply and securely to your board.
A large diameter leash ring: the strongest on the market.
A towing ring for safety but also because it's really practical to have an attachment point on the nose during transport, at anchor, or to secure a camera.
A fin with a quality shape and a US box compatible with all the best fins.
A spacious and sturdy rolling bag.
A super-efficient dual-action pump.
A repair kit is also included in case of damage (please note that the kit does not include glue, which you can easily find at your local hardware store). We also stock the components for your board, making it relatively easy to repair.
