Wing Foil Board Lethal FSP Pro
















Program
The best board ever in the surf.
Presentation
The Lethal is 2000% surf.
Finesse, glide, and maneuverability at levels previously unknown, the Lethal revolutionizes surfing with a shape fully optimized for high-performance wave riding.
Big innovation on the deck to improve comfort with a recessed deck under the pad. The board is thinner, and you pilot the foil more directly.
Relatively long, thin, and narrow for a compact type of board, it offers a glide that blurs the line between gliding and flying. You can hit the whitewater at full speed with complete confidence. The same goes for big airs and committed carves: contacts with the water are no longer an issue and become part of the wing surfing game.
We wanted a board that glides effortlessly, with total fluidity and no interruptions: the new Lethal delivers 100% on this vision.
No more need for overpowered winging either, as this insane glide allows you to get going so early that you can ride with small foils and wings effortlessly. Sessions feel light and perfectly fluid.
Its very reduced OFO nose allows for smooth carves with absolute control and minimal bulk. With a perfectly refined shape and reduced OFO nose and tail dimensions, the Lethal offers total control to surf legendary waves like Punta Preta, as well as linking turns and airs together in everyday conditions.
Its slim profile ensures direct contact with the foil, providing precise support and instant responsiveness.
The design of the hull outline is special, featuring a round pin tail in contact with the water—the most effective tail in aggressive waves! This is a key element of the board, which stems from top-level competition with Malo Guénolé, and has no limits.
Available in 6 sizes, from 4'8" (50L) to 5'6" (100L), there’s definitely a Lethal that will meet your expectations.
There are dozens of strap adjustment options, either centered or offset, which can be set up for a surf-oriented stance or a more symmetrical freeride stance, with double anti-rotation screws. The pad provides powerful grip that secures your footing in critical situations. Having firm straps and ultra-safe grip is a real confidence booster. This board, part of the compact gliding shapes family, comes with non-extended boxes to save weight.
A magical board for surfing, with early take-off and flawless glide, it’s the board for riders who love carving and going full send in the air.

Outline
This is the narrowest board in the range for its volume (with the exception of the Cruzader line). Even sharper than its previous version, it gains glide at takeoff. It's striking! Less width and slightly more length means more off-the-foil speed, fewer touchdowns in turns, less drag when hitting the water, and more control in extreme angles. Its pointed nose makes it very sharp in direction changes, such as top turns. This radical outline makes it the reference board for high-performance wave riding.
Flat rocker
The flat rocker on the rear third maximizes glide, for windsurf-like planing starts. The nose is noticeably higher than on a freestyle board, providing all the clearance needed to handle steep waves.
Hull
The flat hull on the rear third is 100% focused on glide, offering maximum lift for ultra-easy and quick takeoffs, even with a smaller foil. Thanks to its optimized design, you can reduce the front wing area by 200 cm² while maintaining the same takeoff capability. The double concave at the front channels water flow, making touches and landings smoother and painless.
Tail
A flat and round pin tail on the hull enhances glide, reduces bulk in turns, and delivers explosive takeoffs. The tight rocker at the tail ensures optimal water glide before takeoff while keeping some curve to adapt to wave slopes. Touchdowns when surfing are no longer an issue, becoming a natural part of surfing, whether in big landings for pros or while learning tricky moves like a re-entry over the whitewater: just set the board on the water at the critical moment and secure your way down the wave. This new Lethal does it
Rails
Straight and sharp rails at the tail give the Lethal more glide, similar to a windsurf board. The sharp edge increases glide and release, making takeoff easier. In the center, the rails are less vertical. At the nose, they are very softened on the front third, providing more comfort while surfing. You can ride in contact with the water, without any abrupt braking—a top feature for surfing.
Nose
The nose bulb is slightly larger to balance the board's volume and improve stability when at a standstill. The double concave under the nose, coupled with the bulb and narrow outline, makes any touchdown completely painless. Instead of slowing down during nose dives, the Lethal will bounce off the water and come on foil again immediately. It’s truly incredible when landing jumps or for airs in surfing. This absence of punishment encourages trying new moves and will help you progress very quickly.

Buying guide
For whom?
For advanced to expert riders. The Lethal is a technically and physically demanding board. Even though it is easier than previous versions at the same volume, especially during takeoff, a good overall skill level is needed to appreciate it. It is a pro model.
For what?
Surf all types of waves with incredible performance and impeccable control.
Wing or Lowkite, the Lethal is built to take off early, carve with maximum leaning angles and commitment, and glide flawlessly across the water when landing aerials and other surf tricks.
Which board size?
Which boardbag?
Which foil?
The Lethal will be perfect with all high-aspect ranges such as the Fluid or the Ypra Surf or Surf Freestyle. The Curve will be great for its reassuring, easygoing character. And a Sirus L will let you take off super easily while still keeping things playful.
The Curve H: the combo of maneuverability and lift. It is the queen of carving and low end (which doesn’t mean it can’t pick up speed!). It is also the most comfortable for pumping, allowing for numerous connections without burning out your thighs.
The Fluid H: the combo of maneuverability and speed. Perfect for making tight turns, going fast, gliding, and having a very responsive foil. With a very powerful pop added to that, it’s a foil that can truly go anywhere you want, both in the water and in the air!
The Veloce H: the combo of glide, speed, and carves. With these qualities, it is a machine for freeride and long carves, freefly, and downwind. With it, you can glide and connect bumps without limits with unparalleled fluidity. It has a great acceleration capacity on the wave and a low stalling speed, making it easy to fly in all conditions.
The Veloce HDW: 100% glide with a ratio of 13+. Fully focused on endless gliding, the Veloce HDW is the queen of downwind and fast pumping; it also excels in light winds with its infinite acceleration and formidable upwind capability.
The Sirus: the king of light wind. Extreme lift while maintaining glide to generate apparent wind—that’s the Sirus’s magic recipe, letting you ride for hours while others watch from the beach, even in small swell.
The Ypra Surf: the fast surf foil. It delivers the greatest control to date during intense surf phases: high speed, steep drops, sharp slopes, powerful turns. Thanks to its reduced volume, it also avoids repopping too hard and throwing you off balance. Everything stays under control.
The Ypra Surf Freestyle: the ultimate mix of jumps and radical surf. This foil is a ball of energy that lets you take off instantly, pop instinctively, and even repop almost higher ;-) In the surf, it’s explosive—making it particularly suited to softer conditions.
Which stabilizer?
Combinations:
Ideally, we recommend pairing a Ypra Freestyle stabilizer with your Ypra Surf-Freestyle front wing, as these two elements are designed for the same purpose and optimized to work in perfect harmony.
Size:
The ideal size will depend on your board, skill level, weight, spot conditions, and front wing.
We’ve calculated all stabilizer and front wing pairs so that, for example, an M is ideal with an M in all models.
But you can also play with the size:
- A larger size (L for FW M) will give you more front foot support, firmer footing, less liveliness, and reduced speed. It's reassuring but less performance-oriented.
- A smaller size (S for FW M) will offer less stability, more responsiveness, greater acceleration, and more radical performance. Highly effective but somewhat unstable.
Note that instability can also be an advantage—for pop, of course, and for surfing to some extent. The positive side of instability is its reactivity. It's up to you to decide if that’s what you’re aiming for.
