Carbon Full HM Mast Technology

The High Module Carbon offers unparalleled rigidity, representing the pinnacle of performance in our most advanced wings and masts, which face the most demanding structural constraints.

This 100% High Module construction emphasizes performance. This fiber with extraordinary properties allows us to create bold and technically complex shapes.

The products have no flex; fibers are oriented along multiple axes to lock in bending and torsion, ensuring maximum responsiveness.

Thanks to pre-impregnated fibers, we can guarantee optimal resin usage, providing perfect cohesion at the lightest weight possible.

Each layer of carbon is carefully hand-assembled around a high-density hydrophobic foam core, in a steel mold. A central stiffener is integrated to increase rigidity without compromising on lightness.

The mold is then subjected to high pressure and heated to 150°C to solidify the carbon. The foam core, seeking to expand under the heat, ensures even compression between the layers of carbon, guaranteeing a strong and durable structure.

Durability and repairability are at the heart of our development philosophy. Our foils are tested and proven by dozens of team riders, hundreds of employees, and thousands of customers worldwide. Even in case of damage, our products can be repaired multiple times, ensuring exceptional longevity.

TORAY M40J high modulus carbon offers incredible stiffness. It is a very high-end carbon, 4 to 6 times more expensive than the excellent prepreg, and which delivers high mechanical properties while remaining resistant. A carbon popular in aeronautics as well as for high-end sports equipment. Its mechanical characteristics such as its superior tensile strength and Young’s modulus make it possible to obtain exceptional performance on the water.

Used on 5 axes in our masts, the high modulus carbon locks flexions and all forms of torsion. Not that it cancels them, even if it reduces them enormously, but above all it allows a return to the initial shape in record time, guaranteeing the best possible dynamism. The steering is incredibly precise.

Prepreg carbon is carbon fabric that has been pre-impregnated with the exact amount of resin needed to achieve its best performance. The manufacturer of this high-end fabric freezes the set that we cut with templates. Then we apply layer after layer in the mould. When heated up, the resin takes on all of its bonding strength to bind the layers. So you have no excess resin, no drips, no defects that you might have if the resin was applied by hand. And above all, you have a dynamism boosted by a minimal quantity of resin which does not let the carbon “float” in an excess of resin. We have a maximum of carbon in the mix and therefore efficiency.

The Foam Core is an essential element because it allows us a clever mix of compression during molding to give maximum cohesion to the prepreg and high modulus carbon layers. It floats and it is waterproof. The whole thing is stronger and lighter than a full carbon mast, even if it may seem counter-intuitive.

We cut this Foam Core lengthwise in 2 pieces to insert a stringer halfway down the profile. This full carbon beam binds the two sides of the mast and works to block bending. The gain in rigidity is monstrous with this stringer which acts like on a surfboard. Have you ever surfed a board without a stringer? If so you can measure the gain in stiffness of this stringer in all our HM masts.

Everything is pressed and cooked in a steel mold, a real work of art at $25,000. Aluminum molds are more economical but deform, which is why we don’t use them. You will understand that performance involves investments that justify the slightly higher prices of our carbon masts, but still much cheaper than competing products.

Our foils are completely dismountable to adapt to all sports at a lower cost and gives you the possibility of replacing a damaged part. A complete catalog of spare parts is available, to allow you to make it compatible with multiple supports (surf/SUP/kite/wing), and to explore the entire range of use of the foil in each sport and at all levels.

Note on this subject that GONG is at the forefront of the development of foiling. We were at the origin of the creation of the largest foil factory that produces the major brands today. 18 months of intense work and dozens of tools developed. So don’t imagine that our foils are made in a dismal garage. We develop all our products according to the rules of the art, with many in-house engineers, passionate designers, cutting-edge 3D software, countless tests, with Team riders at the highest level. This is what allows us to offer low prices and refined products: we know what we are doing from A to Z.
