Foil Carbon Mast HM 77 cm V3







Program
77HM masts for surf foiling, SUP foiling, and pumping.
Presentation
The 77HM carbon mast is a masterpiece of technological expertise. Glide, stiffness, lightness, and responsiveness: it’s the essential mast for foilers seeking excellence.
It allows you to unlock your full potential in high performance. Stunning accelerations, insane top speeds, instant response in carves, sharp and precise pop, and highly efficient pumping.
Its construction with High Modulus Prepreg carbon increases the fiber content in the composite. More carbon and less resin make it hyper-stiff and reactive. In addition to this material work, the application is meticulously designed and calculated. Flex and twist are perfectly controlled through optimized orientations of the carbon fiber layers. Finally, the high-density core of the internal structure is reinforced with a double 50-layer carbon stringer. This results in formidable dynamics even with thinner profiles and more fluid than structural designs.
The sleek profile minimizes drag for easier takeoffs, rapid accelerations, and higher top speeds. The 77 cm length is dedicated to high-performance use in surf foil or SUP foil, but also in downwind and pumping, and potentially in wing.
With 10 years of mass-producing foils, GONG has been the world’s leading driver of this practice, delivering nearly 100,000 foils. This incredibly intense tenth year of R&D has enabled us to offer an even thinner mast in the V3 foil range. The lower sections of our HM masts now start from 15mm in thickness, while also offering options by 19mm.
You can thus choose the mast perfectly suited to your build, your front wing, and your program:
- If you prioritize glide and speed, the HM15 will become the centerpiece of your quiver.
- If you are sturdier or focused on pumping/light wind, and you seek unmatched rigidity for maximum precision, the HM19 is made for you!
EVOLUTION OF THICKNESS
The mast section is progressive, thinner at the bottom to reduce drag in flight, and thicker at the top to maximize the mast’s stiffness.
INTEGRATED TOP PLATE AND HEEL
The top plate and heel of the HM masts are molded as a single piece with the rest of the mast. There are no connections, so there is no play and the entire structure is ultra-stiff. The mast provides the foil with extreme responsiveness and ultra-precise handling.
CONICAL FITTING
The self-tightening tapered fitting gradually settles in during the session to lock all movement. This fitting eliminates any play and offers unmatched responsiveness and effort transmission.

Buying guide
For whom?
For those who want the best. These masts are not reserved for experts. An intermediate rider will appreciate the advantages of these masts, which offer perfect control of the foil. Of course, HM masts become indispensable as the rider’s performance demands increase.
For what?
The 77 cm length is primarily designed for surf foiling and SUP foiling. It offers an ideal range for pumping, a lot of pop, and more aggressive turns.
It is also perfect for dock starts from a slightly higher dock, and its dynamic qualities provide highly efficient pumping.
It is also well-suited for downwind in smaller conditions that require being high on the foil, especially since its stiffness allows the use of large front wings.
What thickness?
You have the choice between 2 thicknesses.
The thicker the mast, the stiffer it is and the greater control it provides, particularly with larger front wings.
The thinner the mast, the faster it is, increasing top speed and acceleration, especially with smaller wings. Here are our recommended mast thicknesses to ensure perfect stiffness of the whole setup:
- The 15mm thickness is recommended for front wings up to 140 cm wingspan.
- The 19mm thickness is recommended for front wings up to 210 cm wingspan.
Equipments
The mast comes with all the necessary hardware to mount it on the foil:
- 4 M6 brass square nuts
- 4 M6 bowl washer
- 7 chamfered head M6x30mm screws
- Torx T30 key
Delivery
Delivery delay
We indicate a preparation and shipping time of 3 working days. In reality, the majority of orders are shipped within 24/48 hours.
The delivery time, i.e. delivery time of the package to your home, then depends on the delivery location and the carrier.
We work with reliable and efficient carriers. 99% of shipments go perfectly and quickly. In the case of the remaining 1%, rest assured that we will do what is necessary with the carrier.
Shipping fees
Unlike other sites, shipping costs are not hidden behind the price of our products. You know exactly what shipping costs you, and you are not disadvantaged if you choose to collect your order at our GONG Space Center.
Shipping costs are calculated based on the weight and volume of each package, and your delivery address.
Tracking your package
Delivery tracking is managed directly by the carriers to whom we have entrusted your packages. They will contact you by email or SMS to allow you to choose delivery methods and follow the route of your package.
Carriers
We work with the best transport societies to deliver to you throughout Europe and the world within very short deadlines. We chose them for their quality of service and their compliance with deadlines.
For mainland France, 80% of your orders arrive at their destination in less than 48 hours of processing.
For Europe, delivery times vary from 3 to 6 working days, depending on the country of destination.
For the rest of the world, delivery times depend on transit time and customs clearance time. This delay depends on customs and can last from a few days to a few weeks depending on the destination and seasonality.
Please note, transport time is added to preparation/shipping time. Two companies collaborate on your order (GONG and the carrier). Each one masters its activity and is committed to optimizing its deadlines so that you are delivered as quickly as possible and at a reasonable price.
Eco-responsible packaging
Preserving the environment is an absolute priority. This is why we do everything possible to reduce our ecological footprint.
The most important thing is to sell quality, durable products that will be repairable and will please you for a long time.
For our shipments, we use:
Scotch craft paper.
Final packaging in high-end cardboard.
For rigid boards: Flexi-Hex, very high resistance ecological packaging.
This means:
Reusable and recyclable packaging.
An almost total reduction in single-use plastic.
Maximum protection and impact resistance for rigid boards thanks to the innovative Flexi-Hex honeycomb design (35mm thick).
Receipt of your product
Upon delivery, check the condition of your package in the presence of the carrier. A complete explanation email on the procedure to follow will be sent to you when your order is shipped.
Despite our requirements and all the care we take in the packaging and protection of your product, transport hazards may occur, and your product may suffer more or less significant transport damage.
Note that the products are protected in their carton. If you have any doubts, simply refuse delivery and contact us.
