MATOS: EXTENSIONS AND ADAPTOR FOR YOUR FUSELAGE
Adapt your foil to your specific needs with the adaptor or the various extensions offered in our spare parts catalog...
Carbon rear extension to the Pro fuselage to increase the footing and the stability of the foil.
The rear extension to the Fuselage Pro increases the footing of the foil and gives it extra stability.
Ideal for a beginner since the porpoising effect is naturally attenuated by a longer fuselage which will increase the length of the oscillation accordingly. These stab extensions will allow you to progress even faster.
The foil is calmer. You have more time to react. And it responds less abruptly to your hazardous requests !
These fuselage Pro extensions will also have the effect of lengthening your curve radii and requiring a little more downforce. The foil will be generally less lively, depending on the extensions used. Perfect for more relaxed rides.
These parts are also perfect/essential for windsurfing enthusiasts who want to wind foil with their GONG foil.
Two versions of the rear extension are available depending on your need for stability:
The 9.0cm extension will be used mainly in wing, surfing and SUP foiling, while the 16cm extension will be the most suitable for wind foiling.
These extensions are compatible with all Pro stabilizers as well as Pro fuselages Alu and Titanium.
These parts have no play other than the 2/10ths required for assembly/disassembly. This micrometric play is essential but perfectly blocked by tightening the screws.
The only restriction is repeated jumps which we do not recommend. These parts are designed to withstand it, but this is not what we recommend. It’s great for cruising, not as much for sending huge rotations ?

More infos
Foiling involves significant risks of accidents. Poor control of a foil can result in cuts, serious injuries, or even death, to yourself or others.
Foiling must be practiced with all the usual precautions required for surfing/SUP, plus those specific to foiling. Remember that a foil is long, sharp, and can reach high speeds. Being hit by a foil, or hitting someone else, can have dramatic consequences.
Always foil far away from others, in safe, obstacle-free waters.
Wear a helmet and a protective vest that ensures buoyancy. Always wear a full neoprene wetsuit.
When handling the foil, be careful not to cut yourself on the trailing edges.
GONG disclaims all liability in the event of an accident involving a GONG foil. Foiling is practiced entirely at the user’s own risk.
