Program

The narrow surf foil board that offers maximum speed and radicality.

Presentation

The Lethal is truly THE ultimate pro board.

Paddling into the biggest wave, tow-in on massive swells or even carving at lightning speed, nothing can resist it.

Allowing an incredible paddling speed, it will also be perfect for using ever smaller foils or even to catch waves lacking power.

With such a small width, control in carves is precise, powerful and perfect even in the most extreme leaning angles.

The flat deck maximizes control, power and the feedback. You are in total control and approach each of your turns with confidence, you can push even more.

If you have a good enough level, this is the perfect board to ride almost any wave on this planet and push your performance to the maximum.

Shape
OUTLINE

The very narrow outline of the Lethal provides a very fast paddle and allows you to easily ride all types and sizes of waves.

ROCKER

The rocker is low but accentuated by the design of the hull. The latter lightens the board in complex phases.

HULL

Its new hull with an optimized double concave nose cushions the contacts by dissipating the energy and guides the board in the axis before takeoff.

NOSE

Its new nose bulb gives that little extra forgiveness that changes everything. With this additional volume at the nose, we are obviously faster when paddling and therefore when taking off. But we also have a real gain in surfing, especially when pearling or landing a trick: the board pops back up immediately.

RAILS

Faceted rails so as not to catch water in sequences of tight turns.

The facets on the rails allow you to fly with no fear of a sudden brake at the slightest touchdown on a chop or in a tight turn.

TAIL

Round tail for maximum maneuverability.

A narrow board, with a thick tail, the absolute recipe for taking off immediately.

Its kicktail has been reworked to obtain cleaner water exits during repop. When touching the water with the tail, this shape avoids the phenomenon of suction, which is fatal for taking off again.

3D View

Ridge Traction Pad

With its perfect grip and 3mm thickness, the new Ridge Traction Pad provides absolute comfort and grip. Your support is perfectly stable, and your control surgically precise.

FSP PRO Technology

  • Epoxy resin and EPS foam blank: solid and lightweight.
  • Vacuum-packed PVD sandwich deck, hull and rails: unrivalled strength and incredible dynamism.
  • Deck: full PVC/fiberglass/ carbon sandwich made up of a core of high-density PVC foram and 1 layer of 4oz fiberglass and 1 layer of 6oz carbon fiber, with fiberglass reinforcements in sensitive areas.
  • Hull: full PVC/fiberglass/ carbon sandwich with high-density PVC foam core and 1 layer of 6oz carbon fiber, fiberglass reinforcements in fragile areas.
  • Specific foil reinforcements: high-density PVC block for the two US rails. Three layers of carbon cover these boxes. Laminated PVC battens connect the reinforcement to the deck for maximum durability.
  • Rails: the PVC sandwich layer integrally covers the rails for increased structural solidity and very strong impact resistance.
  • Resin tinted hot coat : nobility of the process, weight saving and solidity of the finish.
  • Hand-made matt “custom finish” for weight saving and a better glide.

Buying guide

For whom?

  • From advanced to Pro, the Lethal is a very high level board.

  • From light to heavier riders: the Lethal range offers all sizes.

For what?

Fast to paddle and super lively, this is a board for achieving the highest performance. So you have to surf it with real commitment.


What size of board?



Which foil? 

The Lethal boards are perfect with the Curve H, Fluid H, Veloce H, Veloce HDW or Sirus.

The Curve H is a combo of responsiveness and lift.
It’s the queen for carving and low end conditions (which does not mean it can’t handle speed, on the contrary!). It is also the most comfortable foil for pumping, which allows you to make numerous connections when surf foiling without burning your thighs.

The Fluid H is a combo of responsiveness and speed.
Perfect for turning very short, going fast, glide and enjoying a very dynamic drive. Add to that a very powerful pop and you understand why this foil will go wherever you want, in the water or in the air!

The Veloce H is a combo of glide and versatility.
It is a freefly and downwind machine. It’s the foil to glide and connect bumps endlessly with incomparable fluidity. Accelerations on the wave are stunning and it has a very low stall speed which facilitates flight in all circumstances.

The Veloce HDW: 100% glide.
To be even more focused on infinite glide, the Veloce HDW. The queen in downwinders.

The Sirus : the ultimate high aspect wing to fly longer than everyone else in marginal conditions and for dock start sessions.

What stab? 

We recommend pairing a Veloce H stab with your Veloce H front wing, as these two components are designed for the same program and optimized to work in perfect harmony.

General information on the choice of stab sizes:

The preferred size will depend on your foiling discipline, your level, your weight, the conditions of your spot but also your front wing
