Yes. A foiled Parawing does go upwind. That's not the real question. The real question riders ask themselves when hesitating to switch to Parawing is: at what cost to heading? How many degrees do you leave on the table with each gust, each power adjustment, each transition?
My name is Bruno Sroka. I'm a three-time world champion in Kitesurfing and Kitefoil, and founder of SROKA Company. I've sailed in Kite, Wing, Parawing, in all conditions, on every ocean. And I can say without hesitation: between a standard Parawing and our FYNIX SROKA Parawing equipped with the PushBar System®, the upwind heading difference is 2 to 4 degrees. It may seem small. On the water, it changes everything.
This article explains why upwind performance in Parawing isn't just about the wing, but about how you cut the wing's power. And it shows how the PushBar System® redefines what we thought were the limits of Parawing.
1) The answer in numbers
In foiled Parawing, you go upwind at an angle between 35 and 45° of true wind, depending on the rider, equipment and conditions. This is where everything plays out: 2 to 4 degrees difference in upwind heading makes the difference between a frustrating session and total pleasure. These degrees aren't gained only through piloting skill. They're lost, or gained, based on how the bar lets you manage the wing's power.
Useful definition: VMG (Velocity Made Good) is the speed at which you're actually progressing against the wind. It combines pure speed and heading angle. You can go faster at a bad angle and have lower VMG than a slower rider in a better position. VMG is the true measure of upwind efficiency.
2) The physics of upwind Parawing
Three elements generate upwind capability in Parawing: the Foil, the wing, and their synchronization.
- The Foil is the propeller. Thanks to its hydrodynamic lift, it transforms part of the wing's traction into forward movement perpendicular to the wind. Without a Foil, the board's hydrodynamic drag crushes your heading. With a good Foil, energy efficiency climbs and VMG with it. Our guide details which Foil to choose for Parawing.
- The wing is the engine. Its ideal position upwind is at the edge of the wind window, where it allows better upwind performance. If it moves out of this position, efficiency collapses and so does your heading.
- For a given profile, there's an angle of attack where efficiency is maximum, and a small range around that angle where efficiency stays close to optimum. Moving away from this range degrades the lift/drag compromise, and thus your heading.
A Parawing therefore goes upwind much better when the Foil is efficient (aspect ratio, profile), the wing stays in its optimal position at the wind window edge, and the angle of attack remains stable during piloting. This last point is where everything matters. And this is where the PushBar System® comes in. For the complete wing physics, see how a Parawing flies.
3) The real limiting factor: power management
On a Parawing equipped with a traditional bar, reducing power means tilting the bar to release some of the back lines. This action triggers a cascade:
- The wing's angle of attack changes (the wing pitches).
- The wing moves out of its optimal position at the wind window edge when you pull the back lines.
- Parasitic drag increases because the wing no longer works in its optimal flow regime.
- Your heading degrades.
Worse: to regain power, you pull the other way. The angle of attack changes again. Every action on the back lines costs you heading.
And there's an even deeper problem: with a traditional bar, depower is mechanically limited. Even tilting the bar fully, you only cut a fraction of the power. Direct consequence: overpowered, you suffer. You don't depower, you endure, which generates overpowering, and your heading collapses if you don't have the strength to hold on.
The result compounds. With each gust, each adjustment, your heading degrades a bit more. Over a two-hour session, the gap between perfect piloting and piloting subject to gusts can reach several hundred meters upwind.
On a traditional bar, heading and power are coupled.
4) How the PushBar System® decouples heading and power?
The FYNIX is the first Parawing with true dynamic depower thanks to the PushBar System®. The name "PushBar System®" is a registered trademark of SROKA. The associated innovation is the subject of a patent application filed with INPI, currently patent pending.
You no longer pull the back lines. You push the bar. The lines slide inside the 32 cm carbon bar: this push, dynamic and adjustable based on the intensity you apply, triggers a specific mechanism. The back lines release simultaneously and symmetrically, creating a central break in the wing.
This break isn't a flaw, it's a function. It locally shuts down part of the central lifting surface, reducing the power generated by the wing. The effect felt: as if you just reduced the wing size without moving it.
And this is where it all matters: the wing's overall angle of attack doesn't change. Its position in the wind window doesn't either. The wing stays at the wind window edge, at its optimal efficiency angle. You cut power without degrading your heading.
Depower is modular and dynamic based on need. A light push slightly reduces power; a firm push cuts it significantly. By pulling the bar, the wing regains its shape and full power instantly.
This is a paradigm shift.
- With a traditional bar: reducing power = changing flight geometry = losing heading.
- With the PushBar System®: reducing power = modifying central camber = maintaining heading.
- Heading and power are decoupled. You manage the gust without moving the wing.
The mechanism is detailed step by step in our technical analysis of the PushBar System®.
5) The hidden lever: harness compatibility
The PushBar System® isn't just a better way to reduce power. It's also, and especially, what makes the harness truly usable in Parawing. Before it, harness qualities weren't fully exploited.
- Without a harness, the FYNIX SROKA Parawing flies like a standard Parawing. You hold the bar in your hands, you manage power through pushes. The experience remains comparable to a standard Parawing: the PushBar System® works, but it's partial use of its potential.
- With a harness, the PushBar System® fully activates and multiplies the usable range. Why? Because with a traditional bar, reducing power requires tilting the bar: an asymmetric, unstable movement, poorly compatible with pushing pressure on the board. You fight your own equipment.
- You hook in, and when the gust arrives, you no longer have to choose between holding the wing and depowering: you push the bar, the wing loses power, it pulls less. You keep your heading.
Direct consequence: you can fly a larger wing. A 4 m² where others switch to 2.5 m². A larger wing means easier takeoff, so a wider wind range and better exploitable heading angle. Everything chains together. Discover the SROKA Parawing harness with Kangaroo Pocket.
6) The measured gains
Three gains measured in comparative navigation:
- 2 to 4° upwind heading. Estimate from comparative tests between the FYNIX and market Parawings equipped with traditional bars. Over a 2-kilometer tack, these degrees make the difference between reaching the spot directly and taking an extra tack.
- 4 m² on harness with the FYNIX where a standard Parawing requires 2.5 m². At 20-25 knots, same rider, same conditions. That's 60% more surface, so easier to control in lighter wind and better heading in conditions where you'd normally struggle.
- More consistent heading throughout the session. Because the angle of attack doesn't change during power management, average heading stays high from start to finish of navigation, not just at peak.
7) Parawing, Wingfoil, Kite: who goes upwind best?
Wingfoil is often presented as the upwind reference. Recent facts contradict this.
At the 2025 Wing Challenge in Gruissan, the world's largest event in the discipline (600 entries from 25 countries, Tramontane oscillating between 20 and 30 knots, seven races run), a rider on a closed-cell Parawing prototype dominated run 2, against the world's best Wingfoilers. The performance was judged exceptional, but the result on the water is undeniable. The debate about the future of equipment (Parawing, Wing or Kite) reopened that day. And the 2026 edition, May 11-13 in Gruissan, confirms the momentum: once again, Parawing dominates in strong wind against the world's best Wingfoilers.
The reason is structural. A high-performance Parawing benefits from better aspect ratio and superior efficiency to a rigid wing. At equivalent VMG, or even superior in strong wind, Parawing has better efficiency than Wingfoil. In light wind, Wingfoil keeps a slight edge. Once it blows, the equation reverses.
Kite maintains excellent pure heading but loses on portability, ease of water entry and practice autonomy.
With the PushBar System®, the FYNIX makes this performance accessible: easier to pilot, more forgiving in power management, more efficient in changing conditions.
In light wind, Wingfoil keeps the edge. In strong or gusty wind, Parawing takes over. To go further, also discover our articles Parawing or Wingfoil: which sport for which profile? and Parawing vs Wingfoil: advantages and disadvantages.
8) Technique: how to optimize your upwind Parawing?
A few simple principles that make a session:
- Body position. Hips engaged toward the wind, gaze focused far on your theoretical heading, not on the wing. The Foil follows your center of gravity. The more anchored you are, the better your heading holds.
-
Wing trim. Let it find its optimal efficiency angle. Don't constantly sheet in: this is the main beginner mistake, it degrades flow and pulls the wing out of the window. Good trim is when you feel the wing pulling forward, not dragging sideways.
- Wind reading. Anticipate gusts by watching the water surface. A gust coming: time to push your heading, not sheet in. A lull coming: let the wing breathe, don't force.
-
On the FYNIX on harness. Get on harness early, free your arms for micro-adjustments. This is the hidden advantage of the PushBar System®: you pilot more finely because you no longer have to hold on to control the Parawing.
And especially, the counter-intuitive part. With the FYNIX, too much power is no longer suffered: you push the bar, and you go upwind better. This is the inverted logic compared to a standard Parawing, where the gust degrades your heading. Here, the gust becomes an opportunity.
Frequently asked questions
Can you go upwind in Parawing?
Yes, as long as the Parawing is paired with a high-performance Foil, upwind performance is efficient, consistent and frees you from shuttle logistics constraints.
At what angle to true wind can you go upwind in Parawing?
A good rider goes upwind between 35 and 45° of true wind. Wings equipped with the PushBar System® allow you to gain 2 to 4° additional heading compared to traditional fixed bars.
From how many knots can you go upwind in Parawing?
From 12 knots true wind with a properly sized wing and adapted Foil, upwind becomes perfectly usable.
What is VMG in Parawing?
VMG (Velocity Made Good) is the speed at which you're actually progressing against the wind. It combines pure speed and heading angle: it's the true measure of upwind efficiency, independent of raw speed.
Does the PushBar System® really improve upwind heading?
Yes. The PushBar System® delivers 2 to 4° additional upwind heading by preserving the wing's angle of attack during power management, preventing the sail from moving back in the wind window.
What size Parawing to choose for good upwind performance?
At 20-25 knots, the FYNIX flies in 4 m² on harness where a standard Parawing requires 2.5 m², that's 60% more surface for better heading and more lift in light wind.
Do you need to be expert to go upwind in Parawing?
No, upwind is accessible from the intermediate progression level, but fine heading optimization requires good bar management and water surface reading.
Is a harness essential for upwind Parawing?
A harness isn't essential for sailing, but combined with the PushBar System®, it multiplies comfort, reduces fatigue and significantly increases upwind heading quality.
Parawing or Wingfoil for better upwind?
In strong wind, high-performance Parawing surpasses Wingfoil thanks to its excellent aspect ratio and aerodynamic efficiency. However, Wingfoil maintains a slight upwind heading advantage in light wind.
