Every parawing brand promotes a wider wind range: lifting profile, optimized shape, gust stability. Yet on the water, you see it for yourself: the useful range remains narrower than with wing foil. Here is why, and what it concretely changes for your quiver.
A young market, a locked-in narrative
The parawing is a very recent discipline. To convince wing foil riders to switch, brands have built a narrative around one promise: the parawing would be as versatile as the wing. That is false, and everyone in the scene knows it, from experienced riders to specialist retailers and honest testers. But nobody has an interest in saying so, because the parawing is the segment that will drive growth in the foil market.
The result: a rider invests 500 to 1,100 € expecting to cover a broad range, and discovers a real useful range that is much narrower. Disappointment guaranteed.
The 8 most common arguments, dissected
One common thread runs through most of the market's arguments: the ability to sheet out the wing's power, which affects the sail's angle of attack within the flight window. This is exactly where the real wind range is decided. And this is exactly where the parawing market does not tell the whole story.
- "Stable, lifting profile." On a classic parawing, as soon as the rider tilts the bar (with a left-right wrist movement), the angle of attack changes. Pulling on the rear lines has several consequences: the sail naturally moves back within the window, the angle of attack increases and so does drag, which leads to a loss of upwind ability. So with every bar tilt variation, the angle of attack varies. The fore-aft movement is constant, lift fluctuates instead of remaining stable, and the profile moves constantly. The advertised stability is declarative, not mechanical.

- "Better pointing and upwind hold." With every gust and every bar adjustment, the wing's angle of attack changes, so the sail moves back in the window and loses degrees of pointing. The more irregular the wind, the more the sail works fore and aft, and the more the pointing degrades over time.
- "Shape optimized for light wind." True… but it is an admission. If a brand has to optimize its shape for light wind, it is because its overall range is limited and it has shifted it downward. The upper range collapses in return. Optimizing for light wind does not widen the range: it moves it. It forces you to take a bigger foil and board to manage to get going early.
- "Compact and lightweight." This claim is also true… in theory, a light sail flies better. But the argument backfires: to lower prices, production costs must be cut. Material quality is the first casualty. Some brands do not use fine grammages and hydrophobic fabrics, but lower-quality fabrics instead. The wings end up heavier, and therefore less responsive. Consequently, weight is fundamental to performing in light wind.
- "Stability in gusts." In a gust, to reduce the parawing's power, you have to tilt the bar. The goal is to release the rear lines as much as possible to cut as much power as possible. But this solution is a stopgap. You can reduce power slightly… but not by much. So if the gust is too strong, easing the rear lines will have no effect and the rider ends up in survival mode. On a fixed-geometry parawing, it is not really possible to manage the wing's power: you endure the gust, you do not cut it.
- "Healthy in irregular wind." Same mechanism: the wind varies, the rider compensates by tilting the bar, and each compensation moves the sail within the window. A "healthy" wing on a wind tunnel chart is no longer healthy in real, fluctuating wind.
- "Several sizes to widen coverage." This is an unintentional admission. The useful range per size on a classic parawing is about 5 knots. So you need 4 to 5 sizes to cover 12 to 28 knots, and some brands go up to seven or eight sizes in their catalog. The quiver becomes an obligation, not a choice.
- "Broader freeride and downwind use." This argument confuses field of use with wind range. Downwinding allows you to ride longer in passive glide, independently of the wing. It does not distinguish one parawing from another.
The unresolved mechanical lock
All these arguments describe the same problem, never named: a fixed-geometry parawing cannot have its power reduced without its sail moving fore and aft within the flight window. As long as this mechanical lock is not lifted, no optimization of shape, fabric or quiver can widen the real wind range. This is soft-wing physics, not marketing.
The PushBar System®: how this lock was solved
This is precisely the mechanical lock that SROKA broke with the FYNIX. The FYNIX is the first parawing with true dynamic sheet in / sheet out (sheeting), thanks to the PushBar System® (PBS). The PushBar System® is a registered trademark of SROKA, and its associated innovation is Patent pending. This system allows the rider to actually reduce the wing's power while keeping its profile fixed within the flight window.
The mechanism is very simple. The A-lines and B-lines maintain the sail's geometry regardless of bar position. When the rider pushes the bar to reduce power, the angle of attack does not change. The sail does not move back in the window. The profile stays constant.

Several concrete benefits follow:
- Active power management in gusts and at the top of the range, where a classic parawing becomes unmanageable.
- Preserved pointing in irregular wind. The mechanics are simple: on a fixed-geometry wing, an overpowered rider cannot cut power in a gust, they endure it, the sail moves back in the window and they lose degrees upwind. With the PushBar System®, power is cut without the wing's angle of attack changing: the gust passes and the pointing is kept. In our comparative test sessions, the gap ranges from 2 to 4°.
- A useful range per size that extends by up to 5 knots of gusts absorbed at the top of the range, compared with a classic fixed-geometry parawing, whose useful range hovers around 5 knots per size. You cover all sailing conditions with just three sizes, versus five to six usually and up to seven or eight with some brands.

- Less physical: you don't tire and can ride longer.
- Easier board recovery.
- Greater safety in strong gusts.
How many knots does the PushBar System® add, size by size?
Each FYNIX parawing size has a nominal wind range, the one you use with the bar sheeted in permanently, without using sheet in / sheet out. The PushBar System® extends this range upward: when power becomes excessive, you push the bar, cut power without changing the wing's angle of attack, and keep sailing where you would otherwise have had to change parawing. This extension remains a gust margin to absorb, not a new comfortable steady wind: beyond the nominal range, you manage occasional gusts, you do not sail continuously at that level.
| Size | Nominal range | Gusts absorbed with the PushBar System® | Total range (gusts included) | Visual |
|---|---|---|---|---|
| FYNIX 6 m | 8 to 16 knots | +4 knots at the top of the range | 8 to 20 knots | |
| FYNIX 5 m | 10 to 20 knots | +5 knots at the top of the range | 10 to 25 knots | |
| FYNIX 4 m | 14 to 24 knots | +5 knots at the top of the range | 14 to 29 knots | |
| FYNIX 3 m | 23 to 30 knots | +5 knots at the top of the range | 23 to 35+ knots |
The gain is only at the top of the range. The PushBar System® cuts power, it does not create it: the low threshold of each size stays unchanged. A 5 m does not get going any earlier because it is equipped with the PushBar System®.
The PushBar System® requires being hooked into the harness. It is the load transfer through the harness line that lets you push the bar: unhooked, you cannot use sheet in / sheet out.
Reference setup: rider weighing 80 kg, LW 105 L board, UHA range foil suited to conditions, ideally 1260 cm² in light wind and 800 cm² in strong wind. The wind range is a property of the whole system: your weight, your level and the foil / board combination shift it in one direction or the other.
How we measure this gain. The announced gain is recorded in our comparative test sessions at constant setup: same wing, same foil, same board and same rider, comparing sessions with the bar sheeted in permanently and sessions where sheet in / sheet out is used. This is not a comparison with another brand, but the measured difference on the same FYNIX depending on whether you use the system or not.

FAQ on the wind range of a parawing
What is the real wind range of a parawing?
The useful range of a classic parawing is about 5 knots per size. To cover an overall range of 12 to 28 knots, you therefore need 4 to 5 different sizes. With the FYNIX and the PushBar System®, the range per size can absorb up to 5 knots of gusts at the top, adjusting the foil and board size accordingly.
How many knots do you gain with the PushBar System®?
The PushBar System® adds 5 knots at the top of the range on the FYNIX 3, 4 and 5 m, and 4 knots on the 6 m. Concretely, a FYNIX 5 m covers 10 to 20 knots with the bar sheeted in permanently; sheet in / sheet out lets you absorb gusts up to 25 knots, without it becoming a comfortable steady wind. The gain is only at the top of the range: the system cuts power, it does not create it, so the low threshold does not move. It also requires being hooked into the harness, since load transfer is what lets you push the bar.
How many parawing sizes are needed to cover all conditions?
With a classic parawing, 4 to 5 sizes are necessary, and some brands offer up to seven or eight sizes. With the FYNIX SROKA equipped with the PushBar System®, three sizes are enough. With two wings, you cover 90% of your usual conditions.
Why is the parawing wind range narrower than wing foil's?
A parawing with a standard bar has a limit of about 5 knots per size because its geometry is fixed: any power reduction moves the sail within the flight window. The PushBar System® solves this problem by decoupling power and geometry.
Does a fixed-geometry parawing lose pointing in gusts?
Yes. If the rider is overpowered and cannot cut power, they endure the gust: the sail moves back in the window, drag increases and upwind ability degrades. With the PushBar System®, power is cut without any change in angle of attack, so the gust passes without losing pointing. In our comparative test sessions, the gap ranges from 2 to 4°.
What is the PushBar System® (PBS)?
The PushBar System® is a bar system developed by SROKA that provides true mechanical sheet in / sheet out on a parawing, while keeping the sail's profile stable regardless of wind strength. The lines slide inside the carbon bar. It is a registered trademark, and its associated innovation is Patent pending with the INPI.
Why does a parawing become unstable in gusts?
On a classic parawing, handling a gust means tilting the bar, which changes the angle of attack. When overpowered, the profile takes the load and no longer releases power. The PushBar System® allows you to reduce power without changing the flight geometry.
From what wind speed can you ride a parawing?
The useful range generally starts around 10 to 12 knots, provided you have the right size, the right board and the right foil. Below that, the aerodynamic profile stalls and the wing becomes unusable.
Can the parawing replace the wing?
For now, the parawing complements the wing rather than replacing it. It excels in compactness, simplicity and relaunch after a fall. The wing keeps an advantage in wind range over wings without active power management. With the PBS, this gap is significantly reduced.
