The Lethal EPS Pro is a narrow, high-performance surf foil board designed for fast waves, committed turns, and riders who want precise, powerful, and direct control in strapless mode.

Overview

The Lethal EPS Pro is the most performance-oriented surf foil board for fast, powerful, or challenging waves. Its narrow, precise, and highly slippery shape provides maximum control when speed increases, when the slope becomes serious, and when every stance must be accurate.

Its outline concentrates only the necessary width. The nose remains thin, the widest point is contained, and the useful width at the rear foot allows for an effective offset in strapless mode without unnecessarily widening the board. The result: a board that feels direct underfoot, loves to go fast, places itself precisely in the carve, and doesn't overwhelm you when charging hard.

The Lethal is made to push angles to the extreme. Its narrow round tail frees up the turns, limits touch-downs, and maintains a very pleasant continuity of support when the board reconnects. You can descend at full speed, maintain velocity, hold the line, and carve with true steering precision, without the width blocking your choices.

The hull is designed to handle contacts without a sudden brake. On a landing or in a survival descent, contact with the water should not become an immediate penalty. The double concave at the nose channels the flow and softens the touch-downs, the flat central area maintains glide, and the almost vertical kick tail limits suction. The Lethal glides on contact, frees up, and allows you to continue without being stopped abruptly.

Its outline-to-hull surface ratio is closer to 1/1 than on other shapes. Practically, the useful surface under the board remains very consistent with the outline: you maintain real glide on contact, a clear response underfoot that doesn't fail, and it surfs almost like a surfboard without a foil. You can pull into barrels!!! It offers the ability to easily re-pop after a touch-down, a 360 landing, a cover-up, or a carve that touches.

The lowered deck with its concave cockpit brings the feet closer to the foil to enhance the connection with the wing. The stances are more readable, more powerful, and more direct. This precision is essential in fast waves, committed carves, and angle changes where the board must instantly transmit every pressure.

The moderate but maintained width at the rear foot provides enough offset in strapless mode to push hard without cheating or discomfort. The rear foot can be placed powerfully, close to a performance shortboard stance, without having toes in the air. This allows the Lethal to remain narrow without losing the necessary connection in powerful turns.

Its thin point nose reduces inertia at the front and maintains a healthy attitude in the air. The nose bulb provides just the necessary volume under the chest to aid paddling and compensate for the lowered deck, without unnecessarily thickening the stance area. The Lethal thus retains enough glide to position itself in fast waves, start early, and use smaller foils, while remaining lively and precise once standing.

The stretched rocker optimises paddling speed and glide before take-off. The absence of a large nose kick in front avoids violent braking when the board touches. More contact is accepted in glide because it is not fatal: the board planes, glides, frees up, and ultimately encourages engagement.

The boxes are set back compared to the previous shape, in relation to the stance placement. This provides more foil adjustment range towards the rear, with a clear orientation towards control. It's a real plus for calming the board, maintaining more speed, and charging harder in fast or powerful waves.

The Lethal approaches a performance shortboard feel in surf foil: fast lines, powerful carves, precise stances, control on the slope, and the ability to engage without being overwhelmed by the board. It is not made for relaxed surfing or making multiple mistakes; it is made for those who know how to read the wave, place their take-off, and exploit a very direct board.

Built in EPS Pro, the Lethal prioritises lightness, reactivity, and direct sensations. The carbon/glass construction gives a lively, precise, and vibrant board, perfectly suited for strapless riding where you want to retain maximum feedback underfoot.

The new 5 mm Ridge Traction Pad provides very secure grip on essential stance areas, with firm traction and real comfort underfoot. The Lethal comes with a front pad and a tail pad attached, while the separately offered boomerang intermediate pad allows these two areas to be connected for those who want a continuous grip surface.

The Lethal EPS Pro is the board for going fast, descending at full speed, carving hard, holding powerful lines, and maintaining control in pushing waves. A narrow, precise, and radical board designed to transform speed into clean trajectories.

OUTLINE

The outline of the Lethal is narrow, taut, and performance-oriented. The nose remains thin, the widest point is contained, and the useful width is concentrated where it truly aids control: under the chest while paddling, under the front foot, and around the back foot to maintain an effective offset when strapless.

This reduced width helps limit bulk in turns and keeps the board very responsive underfoot. The Lethal glides quickly, positions precisely, and handles strong pressure without feeling like a board that overflows or hinders movement.

NOSE

The nose of the Lethal is thin, pointed, and light to reduce inertia at the front and maintain a very stable attitude in the air. It complements the board's performance programme: less unnecessary surface for a pro, less mass in front, more precision in angle changes.

The nose bulb provides the necessary volume under the chest to maintain effective paddling and compensate for the lowered deck, without unnecessarily thickening the stance area. It helps to maintain support at the start and to stand up cleanly in fast or hollow waves.

DECK

The lowered deck creates a concave cockpit in the stance area to bring the feet closer to the foil. This makes the feel of the board more direct, precise, and powerful, which is essential in fast waves and highly committed turns.

Despite its narrow outline, the Lethal retains enough width at the rear foot to allow for effective offset in strapless riding. This maintains power in the stance, precise handling, and a true ability to charge turns without being locked into the board's axis.

Hull & rails

The hull of the Lethal is designed to maximise glide on contact. The double concave at the nose channels the flow and softens touchdowns, while the flat hull around the foil maintains speed and provides a sharp response underfoot.

The faceted rails reduce the hull surface and minimise contact in sharp angles. At the rear, the rails become more freeing, with sharp edges that allow the water to detach cleanly. The Lethal remains stable when it touches: it glides, releases, and allows you to continue the carve without a sudden brake.

TAIL

The narrower tail behind the back foot of the Lethal releases the turns and limits touches in committed angles. It allows you to push hard on the foil, maintain a fast trajectory, and keep control when the wave accelerates.

The round tail retains just the right amount of smoothness and continuity in the supports, while the verticalised kick tail facilitates clean water exits after contact. The Lethal does not seek the massive lift of a wide tail: it prioritises precision, glide, and freedom in powerful turns.

New ridge Traction Pad

The new 5 mm Ridge Traction Pad delivers secure, comfortable grip across the key pressure zones. Its texture stabilizes foot placement, reduces micro-slippage, and enhances control during the most demanding phases of riding: pumping, committed turns, low landings, and re-accelerations.

Its three-piece layout lets you adapt the grip surface to your riding style. The front and rear pads cover the main pressure zones while maintaining a radical look and optimized weight. The intermediate boomerang pad, available separately, creates a continuous traction surface for riders seeking additional comfort and deck protection.

The circular perforations further reduce weight while improving grip underfoot, bringing your feet even closer to the board. The result is a board that feels livelier, more responsive, and more connected beneath your feet.

EPS Pro Technology

Light weight, responsiveness, and targeted reinforcement.

EPS Pro technology is designed for riders seeking the lightest possible feel, maximum responsiveness, and direct feedback underfoot. Its epoxy carbon/fiberglass construction over a high-density EPS core concentrates reinforcement only where loads are greatest, eliminating unnecessary weight.

3D-designed shape developed with CAD software for precise control of volume, outlines, and balance.
CNC pre-shaped blank ensuring perfect consistency from board to board.
Final hand-finishing using traditional templates to preserve the shaper's precision and attention to detail.
Epoxy carbon/fiberglass laminate over a 28 kg/m³ high-density EPS core, reinforced with a single 3 mm wooden stringer to combine light weight, durability, and lively flex.
Deck: one layer of 6 oz carbon fibre to maximize responsiveness, backed by one layer of 6 oz fiberglass for impact absorption.
Bottom: one full layer of 6 oz carbon fibre, reinforced with two staggered carbon patches around the US boxes to reduce the risk of damage in this highly loaded area.
Rails: the deck laminates overlap the bottom laminate, creating a three-layer carbon/fiberglass/carbon rail structure that maximizes impact and flex resistance while increasing overall stiffness and responsiveness.
Foil box construction: a 35 mm thick, 80 kg/m³ high-density PVC foam insert fully integrates the twin US boxes into a rigid, waterproof structural block.
Pigmented hot coat for premium finish quality, lower weight, and increased durability.
Hand-finished matte custom finish to minimize weight while maintaining clean hydrodynamic performance.
Light pink bottom finish to reduce heat build-up by reflecting more sunlight.

Even with this light-coloured finish, an EPS board should never be unnecessarily exposed to direct sunlight or excessive heat.

Buying guide

For whom?

The Lethal EPS Pro is designed for advanced to pro riders who want a narrow, fast, and ultra-precise surf foil board, crafted for powerful, fast, or challenging waves.

It is ideally suited for those who can perfectly read the waves, position themselves correctly, and make the most of a direct board underfoot. It is most beneficial for riders who want to carve hard, maintain fast lines, use smaller foils, and keep control in conditions where speed and precision become priorities.

The Lethal EPS Pro is a strapless board. It prioritises freedom of stance, direct sensations, and the lightness of the EPS Pro construction. For strapped use, heavy tow-in, or repeated aerial tricks, the FSP Pro version will be more suitable thanks to its strap inserts and full carbon/glass sandwich construction.

To avoid if...

The Lethal EPS Pro is not the best choice if the goal is to have an easy, forgiving, voluminous, or very accessible board.

It is also not ideal if the rider is looking for a very compact board, ultra-easy for pumping, made for short snaps, opportunistic connections, or small mushy waves. The Lethal requires more speed, more reading, and more commitment.

If the goal is to start, paddle leisurely, or maximise comfort in weak conditions, a more accessible or elongated shape will be more suitable. The Lethal makes sense when the wave pushes, when the slope forms, and when the rider wants to turn speed into trajectory.

For what?

The Lethal EPS Pro is made for fast waves, powerful curves, and situations where control must remain total despite the speed. It allows for early take-offs, holding a line, descending at full speed, pushing hard, and keeping a stable board during water contact phases.

Its narrow shape reduces bulk and improves precision in curves. Its narrower tail frees up angles. Its hull, close to the Lemon spirit, accepts contacts without abrupt braking. The Lethal thus allows for more engagement in serious waves, with less penalty when a mistake brings the board into contact or when you want to ease off.

It is also very relevant with smaller, faster foils. Its paddling speed, glide on contact, and control allow for exploiting more performant setups, with a board capable of keeping up.

Understanding the GONG range

`

What board size?

The choice of size depends on weight, skill level, spot, wave power, and the type of foil used.

Smaller sizes are for expert riders who want maximum precision, liveliness, and control in fast waves or with high-performance foils. They require solid paddling, good timing, and precise positioning.

Intermediate volumes offer the best balance between paddling, control, and performance. It's often the most coherent choice to exploit the Lethal in varied conditions without losing too much comfort at the start.

Larger volumes provide more paddling speed, more stability under the chest, and more leeway in fast, powerful, or technical waves. They allow for earlier take-offs, secure positioning, and using smaller foils with more comfort.

Refer to the size chart to choose the appropriate volume based on weight, skill level, usual conditions, and the foil used.

If hesitating between two sizes, opt for the larger one to gain paddling speed, stability, and consistency in fast or technical waves.

Choose the smaller one only if the skill level allows compensating for the loss of volume and if the primary goal is maximum precision, liveliness, and control in already sufficiently powerful waves.

Which foil?

The Lethal will be perfect with the Curve H, Fluid H, and Veloce H ranges.

Each of these high-performance wings has its strengths on which the development has been particularly focused:

The Curve H: the combo of manoeuvrability and lift.
It is the queen of carving and low range (which does not mean it cannot rev up!). It is also the most comfortable for pumping, allowing for many connections without burning your thighs.

The Fluid H: the combo of manoeuvrability and speed.
Perfect for very tight turns, going fast, gliding, and having a very responsive ride. Add to that a very powerful pop, and it's a foil that truly goes wherever you want, in the water or in the air!

The Veloce H: the combo of glide and versatility.
It is a freefly and downwind machine. With it, you glide and connect bumps without limit with incomparable fluidity. It has a great acceleration capacity on the wave and a very low stall speed, making flying easy in any circumstance.

The Veloce HDW: 100% glide.
To be even more focused on the infinite glide program, the Veloce HDW. The queen of downwind.

The Sirus: wings with the ultimate ratio for flying longer than anyone else in marginal conditions and dock start.

Which stabiliser?

Example: Preferably, we recommend pairing a Curve H stabiliser with your Curve H front wing, as these two components are designed for the same program and optimised to work in perfect harmony.

General guidelines on choosing stabiliser sizes:
The preferred size will depend on your support, skill level, weight, spot conditions, and your front wing.
