The Lemon FSP Pro is the ultra-versatile modern strappable surf foil board, designed to carve hard, pump efficiently, connect, and perform in a wide range of conditions with a semi-compact, precise, and well-balanced shape.

Overview

The Lemon FSP Pro is the quintessential modern surf foil board: semi-compact, high-performing, intuitive, and well-balanced. It combines enough length to maintain paddling efficiency, enough compactness to stay lively while pumping, and enough useful width to offer control in turns without becoming cumbersome.

Its semi-compact shape concentrates volume where it truly matters: under the chest, the front foot, and in the stance area. While paddling, the Lemon maintains good balance and efficient glide to position cleanly and achieve aggressive take-offs. Then, its contained length limits inertia and allows for precise foil control.

The outline is designed to offer real freedom of stance without excessive width. The midsection remains buoyant, the tips are refined, and the rear foot retains enough space to charge turns strapless with a natural offset just before the winger. This balance gives the Lemon its all-around character: high-performing, maneuverable, readable, and effective in a wide variety of conditions.

The rear winger is a key point of the shape. It allows for a significant reduction in width near the tail while maintaining a squash tail. The board retains re-pop, support, and efficiency, but the tail touches less in turns. Result: more engaged turns, less clutter under the rear foot, and a board that can be pushed hard without becoming physically demanding.

The lowered deck with a concave cockpit brings the feet closer to the foil to enhance steering precision. The connection with the foil is more direct, the stances are more readable, and each weight transfer translates immediately into the foil. You can carve hard, pump efficiently, and change direction with a real sense of control.

In the FSP Pro version, dedicated strap inserts for surf foil stance add an extra dimension of control. The straps position the feet correctly, allow pushing and pulling on the board, improve pumping, limit stance errors, and facilitate recovery from mistakes. The Lemon maintains its natural balance but allows for deeper stances, aggressive carves, tricks, and towed uses.

The hull maximizes the useful surface around the foil to maintain efficiency before take-off, during pumping, and in contact phases. The double concave at the nose channels flows and softens touchdowns, while the flat central area provides efficient glide and a sharp response that boosts relaunch.

The recessed and verticalized kick tail limits suction when the board touches the water. Combined with the liberating rear rails with sharp edges, it allows maintaining speed on the water and easy re-pop: essential for engaging without excessive apprehension of contact. The Lemon remains stable when touching, the contact is integrated into the normal behavior of the shape, which gives confidence to carve harder and attempt more on critical sections.

Its pumping efficiency is one of its great assets, boosted by the straps. The Lemon allows easy acceleration, returning to the peak, restarting, and chaining together.

It's not made for just one style: it allows varying rhythms, carving, pumping, playing with sections, and remaining high-performing in many configurations, especially with the straps that allow sending it without limits in the air as well as in big towed conditions.

Constructed in FSP Pro full carbon/glass vacuum sandwich, with high-density PVC foam on the deck, hull, and rails, the Lemon gains in rigidity, responsiveness, and durability. This construction withstands the efforts of powerful stances, harsh landings, aerial tricks, strapped and towed use, while maintaining ultra-precise steering.

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

The Lemon FSP Pro is the board for sessions where everything needs to be done well, but with a superior level of control and durability: starting cleanly, pumping efficiently, carving hard, connecting, maintaining control, and pushing maneuvers further, strapless or strapped.

OUTLINE

The outline of the Lemon is semi-compact, with a contained overall width and a buoyant middle third. The volume is placed where it really matters: under the chest for paddling, under the front foot for stability, and in the stance area to maintain comfort without creating clutter.

This distribution results in a very balanced board: enough glide to position yourself cleanly, enough compactness to remain lively when pumping, and enough useful width to carve strapless with a natural offset. The Lemon remains readable, performant, and easy to exploit in many configurations.

Nose & Rocker

The round nose of the Lemon maintains width at the shoulders to provide paddle support and stability during take-off, then quickly tapers to a lighter point. This retains useful volume without unnecessarily loading the nose.

The nose bulb compensates for the lowered deck and allows for volume retention at the front, while keeping a stance area closer to the foil. Combined with a fairly flat rocker, it enables the Lemon to make the most of its length, glide smoothly before take-off, and maintain a stable attitude in more committed starts.

DECK

The lowered deck creates a concave cockpit in the stance area. The feet are closer to the foil, making the pressure points more readable and the board gains in precision. You steer more finely, with a true sense of direct connection with the foil.

The available width around the back foot allows you to load the curves with a natural offset, just before the winger. You maintain power in the pressure points without falling into excessive tail width. This is what gives the Lemon its balance between committed carving, control, and ease.

Hull

The hull of the Lemon maximises the useful surface around the foil to maintain glide before take-off, during contact phases, and efficiency when pumping. The core of the hull remains flat to offer efficient glide and a sharp response underfoot.

The double concave placed under the nose channels the flow and softens touchdowns. It limits harsh reactions upon water contact and helps the board remain stable when pushing harder. This hull gives the Lemon true efficiency: it glides, it pops back up, it remains controllable.

TAIL

The tail of the Lemon combines a relatively buoyant squash tail with a pronounced winger at the back foot. The squash tail maintains support, pop, and performance, while the winger significantly reduces the width near the tail to free up the board in turns.

The tail cut of the kick on the hull is set back and verticalised to limit suction when the board touches the water. Combined with the winger and sharp edges, it helps maintain speed on the water, allows for easy re-popping, and enables engagement without fear of contact stopping the board. The contact is integrated into the normal behaviour of the shape.

RAILS

The rails of the Lemon are soft and subtle at the front, with pronounced chines to handle contacts and maintain smooth glide. They contribute to the shape's forgiveness when the board touches the water during a turn, a solid landing, take-off, or a low pumping phase.

At the back, the rails become more vertical and release-oriented, with sharp edges to cleanly detach the flow. This evolution of the rails helps maintain speed, limits touches in committed turns, and ensures precise handling without stiffening the board.

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.

FSP Pro Technology

Full carbon/PVC sandwich construction, strap-ready control, and maximum durability.

FSP Pro technology is engineered for riders pushing strap surf foiling to the highest level. Its lightweight EPS core is fully wrapped in a vacuum-laminated carbon/fiberglass sandwich construction with high-density PVC foam on the deck, bottom, and rails. The result is an exceptionally stiff, responsive, durable board capable of withstanding the extreme loads generated by aggressive surf foiling, aerial manoeuvres, and tow foiling.

Epoxy resin, carbon fibre, high-density PVC foam, and a lightweight EPS core combine to create a structure that is light, durable, and highly responsive.
3D-designed shape developed with CAD software for precise control of volume, outlines, and balance.
CNC pre-shaped blank guaranteeing absolute consistency from board to board.
Final hand-finishing using traditional templates to preserve the shaper's craftsmanship and precision.
15 kg/m³ lightweight EPS core, optimized specifically for high-performance sandwich construction.
Vacuum-laminated carbon/fiberglass construction with high-density PVC sandwich covering the deck, bottom, and rails.
Deck: one layer of 6 oz carbon fibre for maximum responsiveness, a full 80 kg/m³ PVC sandwich, and one layer of 6 oz fiberglass for impact absorption, complemented by localized fiberglass reinforcements in high-stress areas to combine stiffness, durability, and long-term strength.
Bottom: one layer of 6 oz carbon fibre, full 80 kg/m³ PVC sandwich, and one layer of 6 oz fiberglass with additional localized reinforcements to maximize stiffness, direct response, and resistance to foil loads.
Rails: the high-density PVC sandwich fully wraps the rails, significantly improving structural integrity, impact resistance, and torsional stiffness.
Foil box construction: a 35 mm thick, 80 kg/m³ high-density PVC foam insert fully integrates the twin US boxes into a waterproof, ultra-strong structural block. Three carbon layers reinforce this area, while vertically laminated PVC shear webs connect the insert directly to the deck, creating an exceptionally rigid foil-to-board connection and increasing long-term durability.
Dedicated reinforcements around the footstrap inserts withstand heavy pulling forces, powerful landings, and aerial manoeuvres.
Pigmented hot coat for premium finish quality, reduced weight, and enhanced durability.
Hand-finished matte custom finish to minimize weight while maintaining excellent glide.
Predominantly white finish to minimize heat absorption compared with darker colours.

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

Buying guide

For whom?

The Lemon FSP Pro is aimed at advanced to pro riders who want a modern, high-performance, and well-balanced surf foil board capable of carving hard, pumping efficiently, and remaining stable in various conditions, with the added control and durability of full carbon/glass sandwich construction.

It suits those who want a semi-compact board: short enough to keep liveliness underfoot, long enough to maintain paddling efficiency, and wide enough in the right areas to offer control without becoming cumbersome. It's a board that appeals to riders looking to progress in all directions: carving, pumping, connections, faster sections, small waves, more substantial waves, clean sessions, or less perfect ones.

The Lemon FSP Pro is not just a Lemon with straps. It can also be ridden 100% strapless, with the advantage of a more robust, structural, and durable construction for those who charge hard, demand a lot from their gear, or want a board capable of better handling impacts, powerful landings, and intensive use.

When strapped, it adds a very clear dimension of control. Straps require placing your feet correctly and properly adjusting your foil, allowing you to push and pull on the board, improve pumping, limit stance errors, and facilitate recovery from mistakes. In paddle surf foil, it requires a real level of skill as you need to manage strapping in during the take-off. In tow or wake, it's much more natural: you strap in before the rope tension, then immediately benefit from the control.

The Lemon is not an extreme board in a single register. Its appeal is precisely to offer a very high level of performance with a readable behaviour. It allows you to push hard in curves, vary rhythms, connect and surf for a long time without being hindered by the board. In FSP Pro, it simply pushes this potential further: more control, more durability, more possible commitment, strapless or strapped.

To avoid if...

The Lemon FSP Pro is not the best choice if the goal is to have the most compact board possible, the most radical in pure pumping, or the most extreme in strapless with maximum rear foot offset.

It's also not made for those who want only easy paddling, very early take-offs, and a lot of length to position far out at the peak. The Lemon maintains good glide for its format, but it remains a semi-compact performance board: it requires a minimum level, timing, and commitment.

In paddle surf foil, straps add a real constraint at the start. They become incredible once in flight, but you need to know how to strap in cleanly, stay calm during the take-off phase, and accept a more technical and less natural gesture than strapless. For a rider who primarily wants ease of paddling, strapless freedom, and a board easier to manage under the chest, the Lemon EPS Pro might be more suitable.

If the rider is primarily looking for a very smooth, very long, very forgiving board oriented towards easy paddling and relaxed long lines, a more elongated shape will be more suitable. The Lemon is more modern, livelier, more oriented towards carving and efficiency. The FSP Pro adds even more control and durability, but it doesn't transform the Lemon into a long paddle or relaxed glide board.

For what?

The Lemon FSP Pro is designed to do everything well in surf foil: take off cleanly, pump with efficiency, carve hard, connect, maintain control, and retain enough performance to never limit the level.

It excels when mixing registers is required. A small mushy wave, a faster section, a foam pushing at take-off, a return to the peak in pumping, a strong carve, a sharp change of direction: the Lemon maintains a healthy and effective response. Its semi-compact shape allows it to stay lively underfoot without losing the necessary comfort to chain waves.

Its rear winger reduces the width near the tail, freeing up curves and limiting touchdowns, while maintaining a squash tail that provides support, pop, and efficiency. The flat hull around the foil, the double concave at the nose, the recessed kick tail, and the releasing rear rails allow water contacts to be integrated into the normal behaviour of the shape. You can push harder without fear of a touchdown stopping the board.

In strapless, the FSP Pro mainly brings more durability and structural integrity. It's a relevant choice for those who like the Lemon's behaviour but want a construction capable of withstanding more intensity, impacts, powerful landings, and repeated use.

When strapped, the straps change the potential. They lock in the stance, improve pumping, secure foot placement, increase precision, and allow for more aggressive curves, airs, rotations, brute landings, and towed use. The Lemon retains its natural balance, but with superior control and a much larger margin when pushing hard.

The Lemon FSP Pro is therefore the board for sessions where you want to surf with rhythm: carve, pump, reconnect, restart, vary stances, and keep a high-performance board in many situations. It provides a more complete, modern, and precise surf foil style, with the ability to push much further thanks to the straps and FSP Pro construction.

What board size?

The choice of size depends on weight, level, spot, main use, and desired style.

An advanced rider will choose a generous volume that maintains enough stability under the chest to succeed in take-offs, keep comfort while paddling, and fully exploit the shape's efficiency. This is often the best choice for fast progression, long surfing, and maintaining consistency, especially if used with straps mounted.

An expert or pro rider might go down in volume to gain liveliness, reduce inertia, and maximise sensations underfoot. The Lemon can be surfed very aggressively, but a size too small can lose some of its appeal: its versatility, decent paddling, and comfort in transitions.

For strapless use, the volume choice remains close to that of the Lemon EPS Pro: enough volume for effective take-offs, little inertia to fully enjoy the semi-compact shape. The difference mainly lies in the durability, structural integrity, and longevity of the FSP Pro construction.

For towed use, a more radical choice can be justified more easily if the technical level follows, as the start is assisted and the program focuses more on control, aerials, landings, and tricks.

Smaller volumes favour reactivity, precision, and committed stances. Intermediate volumes offer the best balance between paddling, carving, pumping, and control. Larger volumes provide more stability, easier take-offs, and more margin when conditions are mushy, irregular, or technical.

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

In paddle surf foil, if hesitating between two sizes, favour the larger one for more comfort while paddling, consistency in take-offs, and efficiency in mushy conditions, especially if straps are mounted.

In strapless, the choice can remain close to that of the EPS Pro, with the FSP Pro as a more durable and long-lasting option for riders who charge hard or demand a lot from their gear.

In towed use, the most radical size can be more easily justified if the technical level is up to it, as the start is assisted and the program focuses more on control, aerials, landings, and manoeuvres.

What foil?

The Lemons 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 doesn't mean it can't rev up!). It's 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 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's a freefly and downwind machine. With it, you glide and connect bumps without limit with unmatched fluidity. It has 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 to fly longer than anyone else in marginal conditions and dock start

What 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 board, level, weight, spot conditions, and also your front wing.

What leash?

A short leash, 5’ and 6 mm is sufficient in small waves. A 6’ of 7mm will be much safer as soon as it gets bigger. It's your life jacket, you must wear it to protect yourself and others. It is imperative to renew it every year as it wears out.
