Hollow Full Carbon SCC®: lightness, stiffness and connection

Hollow Full Carbon SCC® technology isn’t simply about making a lighter board. It completely changes the way the structure works.

In a traditional construction, an EPS foam core fills almost the entire internal volume and supports the composite shell. Here, that volume is hollow. Strength comes from two carbon sandwich shells with high-density foam, combined with a true internal structural architecture.

The material is therefore no longer distributed uniformly throughout the board. It is concentrated precisely where the loads actually travel.

The result is approximately 30% less weight than an FSP Pro at comparable volume, but above all, a board with significantly less inertia and a much more direct connection to the foil.

It’s not just a board you notice when carrying it.

Above all, it’s a board you feel less when riding.

Two shells and a true structural skeleton

A Hollow board is not simply an empty carbon shell.

It is built around two molded half-shells made from a premium carbon / high-density foam sandwich, joined around an internal skeleton that is itself structural.

This architecture distributes loads throughout the entire board. Some bulkheads maintain its geometry, while others more directly handle the loads generated by the rider’s heels, the inserts or the boxes.

The principle is very similar to the composite constructions used in competitive watersports: a strong outer shell, precisely positioned internal structural elements and connections that allow the entire assembly to work as one unified structure.

The internal volume remains hollow, but mechanically, the board is far from empty.

A structure engineered around real loads

The skeleton is not distributed uniformly.

Reinforcements are positioned exactly where they are needed to handle loads without unnecessarily adding material elsewhere.

Under the stance in particular, high-density sandwich elements strongly connect the deck to the lower structure. They work on edge, meaning they are oriented to maximize their mechanical strength.

This layout creates a highly rigid structure using relatively little material.

Rider input is therefore not dissipated through a mass of foam. It travels through a dedicated mechanical architecture before reaching the foil.

Less passive material, more active structure.

An extremely direct connection to the foil

The stiffness of the internal skeleton really comes into its own underfoot.

Loads from the front foot, rear foot and lateral inputs are transferred through the deck, then carried by the internal structure directly to the foil area.

The deeply recessed decks further enhance this connection by physically reducing the distance between your feet and the foil system.

The feel becomes much sharper: subtle changes in the foil are transmitted quickly underfoot, while rider corrections produce an immediate response.

When riding strapped, this allows you to push extremely hard through your feet without losing precision.

When riding strapless, reading the board and foil becomes particularly natural.

Less distance, less unwanted flex, less delay between input and response.

Around 30% lighter, but above all much more dynamic

Weight is the first difference you notice.

Inertia is the one you feel throughout the entire session.

A board is constantly being accelerated, moved and repositioned by the rider and the foil. During pumping, carving, rotations, pitch changes or after a touchdown, its mass has to follow every movement.

By removing around 30% of the weight at comparable volume, the Hollow requires less energy through all these phases.

When pumping, it follows the cycle more easily.

Through turns, it transitions more naturally from one angle to another.

In freestyle, there is less mass to initiate and then control.

In freefly, the board follows changes in the foil’s trajectory more naturally.

The difference becomes increasingly noticeable as the riding gets more dynamic.

Every movement becomes easier simply because there is less board to move with it.

Shape precision ensured by molding

A Hollow construction requires a high level of industrial precision.

Each size is produced using its own dedicated tooling, ensuring that the outer surfaces of both half-shells directly match the developed geometry.

Rocker, bottom contours, rails, outline, recessed deck, tail, bulges and volume transitions are all defined by the mold.

This method really comes into its own on shapes where every detail matters. A subtle shift in volume or a localized change in the rail serves no purpose if it cannot be accurately reproduced in production.

Molding locks in these design choices and ensures a high level of consistency from one board to the next.

The shape we develop is the shape we want you to feel under your feet.

Bonding that directly contributes to structural strength

In a hollow structure, the joints are fundamental.

The two half-shells, bulkheads and different structural areas must work together as one. The adhesives used are therefore not simply finishing products: they are an integral part of the board’s structural engineering.

SCC® technology uses technical adhesives capable of withstanding extremely high loads with a minimal amount of material. Development data indicates that these bonded assemblies can withstand tensile loads approaching 700 kg with just a few grams of adhesive.

Highly stressed areas, particularly around the boxes and the connections to the internal skeleton, receive special attention.

The strength of a Hollow board therefore depends as much on the quality of its shells as on the precision with which all its components are bonded together.

A specifically reinforced joint line

The two half-shells meet around the perimeter of the board.

This joint naturally forms an important part of the structure. It therefore features an internal overlapping reinforcement as well as additional lamination on the outside.

The goal is to maintain strong structural continuity around the entire board.

This obviously does not mean that a carbon shell becomes indestructible. Like any high-end composite construction, it withstands the loads it was designed for but remains sensitive to severe localized impacts against hard surfaces.

Strong on the water doesn’t mean indestructible against the corner of a sidewalk.

A better architecture in the event of water ingress

This is one of the major changes introduced by the Hollow construction.

In a traditional construction, damage to the shell can allow water to reach the EPS foam core. The foam can then retain some of that water within its volume.

The Hollow does not have this large block of foam.

Its interior is hollow, while its structural elements use laminated, high-density hydrophobic foam. If the shell is accidentally breached, any water entering the cavity can therefore be drained out.

Drain the board, allow it to dry completely, then repair the shell.

This obviously doesn’t make an impact insignificant, but it fundamentally changes how its consequences are managed.

The board can take on water without becoming a sponge.

Drainage and pressure release: two distinct functions

A Hollow structure contains a sealed volume of air. This means both potential water ingress and pressure variations need to be managed.

The drain plug opens the internal cavity. It should remain open between sessions, during storage and transport, then be properly closed before entering the water.

It also allows the board to be drained in the event of water ingress.

A dedicated tool is supplied for operating and tightening the plug.

The automatic pressure-release valve serves a different purpose: it helps equalize internal pressure during use.

These two systems are complementary but should not be confused.

On land, the board breathes. Before riding, close the drain.

A technology that requires the care of high-end equipment

The Hollow is designed for intensive use on the water, but its architecture benefits from a few good habits.

A sealed hollow board contains air. If exposed to high temperatures for extended periods, this air expands and generates significant internal pressure.

It is therefore essential to leave the drain plug open whenever the board is out of the water, particularly during transport, storage or prolonged exposure to heat.

Severe localized impacts should also be avoided, as with any lightweight, high-performance carbon construction.

You can ride it hard.

You simply need to treat it properly on land for what it is: a high-end composite structure.

SCC®: an industrial technology developed over the long term

SCC® is a proprietary technology developed by our partner factory, which produces this architecture for various high-end brands. It is therefore not a marketing label or certification.

GONG has been working with this factory since 2013, on projects ranging from our first foils to Pro paddles, as well as numerous developments requiring dedicated tooling and specialized composite manufacturing processes.

Hollow technology now benefits from all this accumulated experience: mold expertise, sandwich construction, structural bonding and the production of highly stressed composite parts.

As with the most advanced carbon technologies used in our foils, the final performance does not rely on a miracle material.

It comes from the accumulation of details, all properly mastered.

A different approach to repairability and end of life

Removing the EPS foam core also opens up interesting possibilities beyond performance on the water.

If one of the shells suffers localized damage, the area can be repaired like a conventional composite structure once it has dried completely.

A localized repair to an internal joint may also be possible by creating access to the affected area. However, major structural delamination remains serious damage, just as it would on a conventional sandwich board.

At the end of the board’s life, the absence of a large polystyrene foam core also creates more possibilities for disassembly, cutting or shredding, significantly reducing the volume that needs to be transported.

This does not mean that the board currently has a fully integrated recycling solution.

But its architecture already makes it easier to consider disassembly, volume reduction and recovery of usable materials.

The DNA of Hollow Full Carbon SCC®

Two carbon sandwich shells.
An internal skeleton engineered around the loads it handles.
Around 30% less weight.
Rider input transmitted directly to the foil.
A shape accurately reproduced through molding.
A drainable and repairable structure.

Individually, each of these elements brings its own benefits.

It is their combination that creates the Hollow Full Carbon SCC® feel: a lighter, stiffer, more responsive board that, above all, feels far less present between the rider and the foil.

The shape retains its identity. The foil retains its character.

The Hollow simply removes some of the mass you previously had to move in order to feel them.
