SUP Inflatable I-SUP Race Flat Water - 12'6 x 27 Second Hand 15656

Board in good condition. This is a prototype with a shape similar to the production model, featuring a slightly smoother deck pad. It shows typical, minor signs of wear from friction and some residual sand, along with very faint traces of glue in a few places (purely aesthetic and very subtle).

Racing, training and sporty rides on flat water with a high-end board!


Presentation

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

The I-SUP Race Flat Water is a rocket dedicated to calm waters or to paddlers of a good level .

This comfortable and lightweight board allows for intense physical training, to develop a pro technique, and to achieve great racing performances thanks to its superior quality construction in woven dropstitch fusion reinforced by two stringers.

Its new Ridge Traction pad offers you secure support with all the comfort you will need in these conditions.

The perfect way to shine in the weekend's races!

This is the shape of the board designed for aggressive paddling in SUP, with two sizes available in two widths to find the board that matches your size, skill level and intended use!

And beyond the race, you can simply go out on the water with friends to clear your head, without spending a fortune, without clutter, without risk of breakage, without having to move your garage; and thus just enjoy its very good glide.

And it all fits into a redesigned bag where the board and all your equipment naturally find their place! Zen and sporty.

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

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.

Image

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!

Image

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!

Image

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.
Image

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 or athletic paddlers. Nothing insurmountable, as the width is reasonable and the outline provides a little room in front of the feet to power through each stroke without hesitation. It remains very easy to use for a flat water board.

However, we do not recommend it if you are a beginner.

For what ?

Its purpose is to glide as smoothly as possible, without becoming a frightening balancing act. It is therefore ideal for calm bodies of water, without being a constant challenge.

Rowing fast, training, sporty outings, racing… That’s what this board loves.

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



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


The 12'6 x 27'' Race FW:

  • Trips of less than an hour and a half on calm water.
  • Downwind: it's hot.
  • Size: ideally less than 85kg but it doesn't matter as long as your level allows you to handle this width.


The 12'6 x 29'' Race FW:

  • Trips of less than an hour and a half on calm water.
  • Downwind: it's doable.
  • Size: ideally less than 100kg but it doesn't matter as long as your level allows you to handle this technical tail.


The 14'0 x 27'' Race FW:

  • Thinnest shape with the best glide.
  • Trips lasting more than an hour on calm water.
  • Downwind sailing: it's a sporty activity.
  • Build: it doesn't matter as long as your skill level allows you to handle this shape.


The 14'0 x 29'' Race FW:

  • A shape with more width, a little more comfort.
  • Trips lasting more than an hour on calm water.
  • Downwind sailing: it's a sporty activity.
  • Build: it doesn't matter as long as your skill level allows you to handle this shape.

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 change it every year. 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 inflatable boards, 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.

Paddle and leash not included.
