The shortboard for performing in quality conditions.
Overview
Surfing the best waves of your life means being in the right place at the right time. It also means being completely in sync with your board, in the perfect rhythm to make the most of those conditions.
That is exactly what the Lethal is made for in “perfect” waves. Its round tail brings total freedom to its radical yet harmonious shape.
You can vary your carving turn radius at will and change lines effortlessly. It is perfect for turning under the lip and adjusting your line in endless Indo tubes, for example.
Not to be confused with a pinched round tail, like a round pin, the Lethal keeps huge versatility with a fairly centred wide point that brings loads of drive and mobility to this modern shape. The opposite of a step-up or a mini gun. The Lethal is quite simply the most manoeuvrable board in the range.
A round tail that is 100% built for carving and pivoting on the spot. Fine rails, especially in the tail, to hold tight carves and grip the face. A centred wide point for maximum versatility. Its efficient shape delivers an ultra predictable feel despite a very playful tail. You can commit with total confidence, with a complete sense of speed and freedom.
It is a relatively easy board to surf because it is so instinctive. You can just throw yourself into it and surf without overthinking. The Lethal is the shortboard dedicated to hollow waves, both super fluid and radical when it is time to score.
Its ability to tighten up carves makes it an essential in any good surfer’s quiver.
Single Tab connection: simple, direct and solid
The Single Tab system features a single, extended base on each fin. This design creates a solid connection with the fin box, making installation simple, fin changes quick, and power transfer exceptionally direct.
On the water, the benefits are immediate. The board responds instantly, the fins work without unwanted play, and every input translates into drive, grip and control. This is especially valuable on high performance boards, where precise feedback is essential at high speeds and through committed turns.
The Single Tab system also makes it easy to fine tune your setup for different conditions. Changing fin size, template or flex lets you refine the board's feel in just a few moments. It provides a clean, durable and efficient connection, allowing you to unlock the full potential of the shape.
Good to know: Single Tab fin boxes are only compatible with Single Tab fins.
Key benefits:
- Simple installation and quick fin changes.
- Direct connection for immediate response underfoot.
- Excellent drive, grip and control through powerful turns.

Buying guide
Who is it for?
For surfers looking for an ultra-manoeuvrable board.
It’s a revelation for anyone who wants performance from a shortboard in their turns.
Power surfers will get a lot out of it because they can push their carves as hard as they want.
Surfers with a refined approach and precise foot pressure will find an ultra-precise board that they can put exactly where they want.
For intermediate surfers wanting their first shortboard. For those looking for an easy, immediate feel on a board that turns +++.
For experienced and expert surfers who’ll take it on trips to Indo or ride it in home sessions.
What for?
A good board is first and foremost one that makes your surfing easier, one that gives you confidence. The Lethal is a benchmark board for the best days, and for heading off on a trip.
To feel just as comfortable in 3-foot waves at your local beach break as on a reef on the other side of the world in 8-foot waves and beyond, and everything in between.
The common thread in these conditions is the Lethal’s ability to bring the same intensity to very different waves. To be able to get the very best out of those conditions, not miss out on them, so every session feels epic.
What board size?
The Lethal comes in a very wide range of sizes, from compact shortboards to longer boards for serious waves. This depth of range makes it possible to find the ideal size and volume for your level, build, paddling and the type of waves you surf.
If you’re advanced or expert and looking for a very reactive Lethal, choose a size close to your usual performance shortboard dimensions. You’ll keep a lively, precise board, capable of drawing tight carves and making the most of its highly mobile round tail.
If you’re a solid intermediate, want more paddling comfort, or surf spots with a lot of moving water, choose a size with a bit more length and volume. The Lethal will still perform, but you’ll gain in positioning, take-off and margin at take-off.
Your choice also depends on the waves you’re targeting. For clean, fast and not overly big waves, a more refined size will give you more precision and mobility. For more powerful, longer or more physically demanding waves, a bigger size will bring more paddling, more entry speed and more comfort in your lines.
If you’re between two sizes, choose the smaller one to maximise mobility, rail to rail and tight carves. Choose the bigger one for more paddling, comfort and margin in more powerful or faster waves. With the Lethal, the wide size range really lets you find the right combination of surfing level, volume and wave size.

What are the ideal waves?
- Size: from waist-high to a solid overhead and beyond.
- Power: it performs at its best in all waves except weak knee-high surf.
- Conditions: it works everywhere but prefers glassy waves, like all of us.
What construction?
We offer different constructions on certain shapes to suit the programme, the conditions, and sometimes simply individual habits too.
In the case of a PU board, the behaviour will differ from an EPS board with the same shape and the same weight. That’s because weight distribution within the board creates a major difference in feel. For two blanks with the same shape, one in PU and the other in EPS, the EPS blank will be lighter because EPS foam is less dense.
With a PU board, it’s the blank that provides the strength and concentrates the weight in its core. The board therefore has very "central" inertia. This gives a very smooth board that forgives mistakes, but is less dynamic. A PU blank will be heavier than an EPS blank.
With an Epoxy board, the blank is very light and the strength comes from the skins. So the inertia is "peripheral", meaning that because the board’s weight sits around the outside of the board, it becomes more mobile, more lively and more dynamic.
The best comparison to explain these differences would be to say that PU inertia naturally gives a single fin feel, very centred, smoothed-out and soft underfoot, whereas EPS gives more of a thruster or even quad feel, with pressure further out, immediate rail to rail response and maximum liveliness.
EPS is generally preferred for boards that need dynamism, so most often in small to medium conditions, broadly speaking in waves where you need to generate speed. EPS is therefore the better choice for shapes where reactivity is the priority, because it’s easier to turn quickly, perfect for waves that call for rapid combinations. For very good surfers, it allows them to push the dynamism of their surfing even further. For progressing surfers, EPS adds that little extra boost in dynamism because the board can pick up speed much more easily, an important point when you know that in surfing, speed is the key to everything. PU is generally preferred for performance shortboards, for boards where you simply need to control your speed.
Everyone has their own feel: surfers used to PU will generally say that "EPS bounces and feels like a stiff board". Whereas surfers used to EPS will say that "PU feels soft, lacks speed build-up, and the board struggles to accelerate". These impressions often come from habit, sometimes from generalisations, and often from preconceptions, so don’t hesitate to move beyond received wisdom when making your choice.
Which fin set-up?
The Lethal is designed as a thruster Single Tab. This set-up is the most consistent with its programme: a fast, fluid and ultra-manoeuvrable board, made to hold its line in waves with push while keeping the ability to draw tight carves.
On the Lethal, the fins need to work with the round tail without locking it up. You need to find the right balance between pivot, grip, drive and control. A set that’s too loose will make the board more playful but less solid in fast waves. A set with too much grip will bring plenty of hold but may reduce the tail’s natural freedom.
The Round set is the most balanced choice. It blends speed, control, pivot and drive evenly. It’s the fin to choose if you want a healthy, accessible and versatile feel on the Lethal, with handling that’s easy to read in most good conditions.
The Leap set is even more neutral and fluid. It doesn’t push the board towards an extreme feel and makes transitions easier. It’s an excellent option if you want to keep the Lethal smooth, natural and easy to place, especially if you’re discovering the shape or looking for a very easy-to-use performance set.
The Power set is more upright, with lots of pivot and immediate response under the back foot. It’s ideal for emphasising the Lethal’s highly manoeuvrable side, tightening up carves, getting back under the lip quickly and delivering a more vertical, explosive surf style.
The Project set is deeper, with lots of grip. It’s the set to favour if you surf the Lethal in hollower, faster or more powerful waves and want to secure your bottom turns, push hard through carves and keep solid hold at high speed.
The Wall set is very raked, with lots of drive and excellent line hold. It will suit surfers who want to lengthen their carves, hold fast lines and get the most out of the Lethal in waves with plenty of wall. It’s the choice for fuller, more committed lines.
The Liner set is projection-oriented, with more dynamic flex and a real sense of speed build-up out of turns. It will be interesting if you want to give the Lethal more fluidity, speed and spring, especially in clean waves that let you link carves with rhythm.
To sum it up simply: Round for balance, Leap for ease, Power for pivot, Project for grip, Wall for drive, Liner for projection. The right set is the one that respects the Lethal’s character: a free, precise board made for powerful surfing in quality waves.
Which shape should you choose?
Lethal or Chemical?
These are two boards that complement each other perfectly. The Chemical is an ultra-high-performance shortboard in small to medium conditions. The Lethal comes alive in waves with push. You’ll draw much tighter turns on the Lethal and accelerate harder on the Chemical.
Lethal or Evolt?
The Evolt is closer to the Chemical: it’s its competition version with even more forward projection. The Lethal keeps the edge in hollow conditions. The Evolt is perfect for linking turns/manoeuvres in weak waves.
To sum it up:
- the Evolt for reverses
- the Lethal for turns
Lethal or Atomic?
They share very similar playgrounds: waves with push.
The Atomic has more character, with a tail that gives it +++ projection and drive. It’s the board for accelerating when you’re already doing Mach 12. Ideal for heavy barrels and laying down big carves on the face.
The Lethal’s reduced tail area makes it a bit more versatile and more playful. You feel both very free in hollow waves to tighten up your turns, and even more comfortable locked in deep in long tubes that require you to manage both your line and your height on the face.
