The Surf Foil Board that offers maximum speed and radicality.


The Lethal Foil is a Brand New Model for high level surfers.

Directly inspired by the Lethal Surf model, our shape that’s dedicated to the most powerful waves, the Lethal Foil has no limits. Many prototypes have led us to this particular shape with rounded point nose that keeps the useful lift and eliminates inertia.

We can clearly see that the reduction of the width is the major axis of this Pro Board. Less width means more rowing speed, less sticking in case of a touchdowns, and more control in extreme angles.

The deck surface is flat for a pure and direct feel.

The Lethal Foil EPS have been developed exclusively for surf foil with a high quality monolithic Epoxy/fiberglass construction, aiming for maximum lightness.

4 Boards from 4’4 to 5’4 for all sizes. With the Lethal Foil EPS, you can surf with a modern, light, solid, dynamic, high quality Board, and all this without breaking the bank thanks to our online sales system (Direct Sales from Shaper to Rider, without intermediaries).

  • The small 4’4 is 28L, which allows those with a high technical level to have maximum performance. The 4’4 is also ideal for small sizes.
  • The 4’8 for 35L is ideal for good surfers who want to combine comfort and performance while having an easy paddling.
  • The larger Boards, the 5’1 for 45L and the 5’4 for 55L, are perfect for the bigger riders thanks to their generous volumes. This volume boosts rowing speed, essential on spots where you can’t get back out while pumping.

The Lethal Foil EPS are mounted with two US Boxes (the standard box for Top Plate Foil on the market, 9cm between them). You can mount all the Top Plate foils in the world according to your wishes and style. It has a Leash Plug on the back to fix your Leash for surf foil sessions. Nothing is missing.


  • Rocker: 100% Foil for faster rowing and pumping without touching.
  • Rails: faceted and generous for take-offs, stability and to avoid touchdowns in turns.
  • Volume: important to reduce length and inertia.
  • Outline: difficult to make narrower: Vmax machine!
  • Tail: wide diamond cut for immediate glide and control in chop without losing speed when hitting.
  • Nose: rounded pin with a very marked V underneath, it makes it easier to manage the touches in the chop.
  • Deck: flat deck plan to keep control despite the volume.
  • Bottom: flat hull for an early takeoff.

Buying guide

For Whom?

From the confirmed to the Pro, the Lethal is a very high level Board.

Light weight or robust: the Lethal range offers all sizes.


What is it For?

Fast in paddling and hyper agile, it’s a Board to go for the highest performance. You have to surf it with a real commitment, even strapped.

A Foil works in a lot of conditions, so it’s not discriminating.

However, the key is to know if you want to tear it up or not.


What Size?

  • The 4’4 is ultimate : light or top level only.
  • The 4’8 is super high performance with a volume that is classic in the surfing world.
  • The 5’1 is also high performance, but with comfort.
  • The 5’4 is super high performance but comfortable for the biggest surfers.

In all cases, they are very compact AND narrow shapes: maximum radicality.


What is the Ideal Foil?

The Lethal is best with our Allvator pro and Monobloc Carbon Foils:

The Clear Pro front Wings (ex Pro) give 5 knots more Vmax to get very high performances. But without spoiling the simplicity we love when linking turns.

The must is to mount these wings with a 70cm Carbon Monobloc Pro Mast.


Quiver Partners ?

SurFoil means surfing when the waves are good and hollow. You will have a wide range of choice in our range.

SurFoil tends to eat up the usual SUP program because it hunts on the same waves. It’s not easy to marry the two but having diversity of a Quiver is always a plus. The SurFoil will typically like the conditions of an NFA for example.

We will often complement a SurFoil Board with a Wing because it is the ideal combination when the wind is rising. The Wing is really the “lift” for a  Surfoil. It’s a completely natural extension of it.


Which Settings ?

A beginner will move the Foil all the way back.

And a Pro will place his Foil between the center and the back third of the boxes.


Which Leash?

A short leash, 5′ and 6 mm is sufficient in small waves. A 6′ 7mm will be much safer as soon as it gets bigger. It’s your lifejacket, you have to use it to protect yourself and others. It is imperative to renew it every year because it wears out.

Included equipments

  • 2 Us Boxes for foil mounting with a 4 screw top plate.
  • Leash plug.



  • We make quality products. We are not “low cost”.
  • We sell simply without an intermediary thanks to the internet: direct from shaper to surfer.
  • If we sold this board in a surfshop, it would cost 799€ (taking into account traditional margins that we should offer to distributers and stores).



The dates of availability of all our products are written on each product page, in the size and colour of the product concerned.

These dates are valid at the moment you consult the site and/or place an order. It is possible that this product may be ordered a few seconds after your consultation. It then becomes unavailable. If you have placed an order, this change does not concern you: the product you order is still available on the date indicated at the time of your order.

We sell several thousand products per week. The stocks are therefore very evolutionary. But our management always shows you the real availability live.

If it’s available online: it’s available 😉



Some articles are proposed in pre-order during their routing to our premises. You can buy this article which will arrive at our place in a few weeks. This method avoids the fair to grab upon receipt of the lot and the disappointed ones who would not order within the hour.

Upon receipt, we will ship it to you as a regular order.

The times indicated on the pre-orders are 95% reliable. First of all, because we only pre-sell finished products that are arriving to us after Customs, and therefore shipped right after. And also, because we add decent margins with concern to the dates announced by the shipping companies or railways.

However, a Worker Strike, a breakdown, an overbooking, can unfortunately happen. In the case of a delay, you will be notified by email (check your spam). It is generally less than a week and totally independent of our good will.

As soon as we receive the container in La Baule, we ship your order within three working days. Then the carrier takes over: delivery time and tracking numbers are under their responsibility.

It is possible that the date displayed on the online for the pre-order of the item you have ordered and paid for may change for two reasons:

  1. All quantities of the batch are sold (most common reason). In this case, orders placed for the first container will be delivered as scheduled.
  2. The container is late and we have to shift the date by a few days. (Strikes, breakdowns, overbooking, can unfortunately happen). You will be notified by email.

We never change the delivery dates of a container without notifying customers.



The dates that we announce are shipping deadlines, which GONG has in stock and available here physically.

We usually give a shipping time within 3 days, but in most cases, we ship within 24/48 hours. Normally morning orders leave in the afternoon for example.

Then the transport service takes over. The variables are then important between the customer being delivered to France (very fast) or Bulgaria (a good week) or to a forwarding agent or to Asia or the USA… You understand that each location has its own type of delay.

We work with serious and well-known carriers. They do their utmost to make you happy even if a snafu can happen. In any case, we are there to make things easier and to arrange our customers.


Shipping Fees: 

Contrary to others, we do not hide shipping costs in the price of our products. At GONG everyone knows exactly what he pays. The transport is charged at its strictest value, and the person who comes to pick up his products does not pay hidden transport fees.

Shipping costs are calculated according to the weight and volume of each package, and your delivery address. To this is added a labour time of order preparation.

The invoicing of the shipping costs is identical in continental France and in the bordering European countries. A surcharge is automatically invoiced for deliveries to the most distant European countries and all European islands.

For a shipment in French overseas departments and territories or outside Europe, our logistics department will contact you before the payment stage to give you an estimate of the shipping costs. You will be able to accept this estimate and pay your order, or refuse it and cancel your order.


Any questions:

We answer you within 24 hours by email. But 95% of your questions are answered on the site. Try to use our contact form which will guide you to all these answers.

Don’t forget to read the Forum, where thousands of users exchange information and experiences.

In any case, don’t panic. If you don’t get an answer during the weekend, it’s normal: the team is resting 😉

We are passionate and professional in our job. Our only goal is to make you happy, as much as possible 😉


Eco-responsible packaging:

Preserving the environment is a top priority. That’s why we are doing everything possible to reduce our environmental footprint.

The first thing is to sell quality products that will last, be repairable and will please you for a long time.

The second thing is to sell for less. Most of the pollution coming from a Board is in its use (the km driven to use it) and in the countless environmental damages you have to do to pay for it. Each euro spent is a sum of damage related to your life quite simply: eating, working hard etc… By reducing the price of our products, we significantly reduce your ecological footprint on this item.

For our shipments we use:

  • Flexi-Hex: ecological packaging of very high resistance.
  • Paper Craft Scotch Tape.
  • Final packaging made of high-end cardboard.

All this for:

  • Reusable and recyclable packaging.
  • An almost total reduction of single-use plastic.
  • Maximum protection and impact resistance thanks to the innovative design of Flexi-Hex honeycomb (35mm thick).


Tracking of your parcels :

The tracking of deliveries is directly ensured by the carriers to whom we have entrusted your parcels. They will contact you by email or SMS to allow you to choose the delivery methods and to follow the route of your package.

If you ask us for this tracking, we will have to do as you do: we will go see on the carrier’s app because they are the ones who manage and are responsible for this job.



We collaborate with the best transport providers to deliver you everywhere in Europe and in the world in very short delays.

We have chosen them for their quality of service and their respect of deadlines. 80% of your orders reach their destination in less than 48 hours of processing in metropolitan and continental France.

For Europe, the delays vary from 3 to 6 days depending on the country of destination.

For the rest of the world, delays can be up to 15 days.

Please note that the transport time is added to the preparation/shipping time. Two companies work on your order (GONG and the carrier). Each one controls its activity and commits itself to optimize its delays so that you are delivered as soon as possible, in good condition and at a reasonable price.


Reception of your Board:

Upon delivery, simply open and inspect the condition of your Board in the presence of the carrier. A complete email explaining the procedure to follow will be sent to you when your order is shipped.

In spite of our requirements and all the care we take in packaging and protecting your Board, transportation hazards may occur. Even if it concerns less than 2% of everything we ship around the world, a Board can suffer a more or less important transportation shock.

But in any case, don’t worry, just refuse it, and a new Board will be shipped back to you.



You can choose to return your products if:

  • You are not satisfied (14 days right of retraction).
  • You want to change an item.
  • You have refused your package.


For each situation, contact us by our contact form to help you.
