Impact on performance:

• Improved stability in turns, increased rigidity for tricks and fast runs.
• Excellent low-end range and highly stable behavior in complex situations: tip-out, high-speed stalls, re-pop, turbulent water, etc.
• Reduced drag enables easier glide and sustained speed over long distances without effort. Requires 200 cm² less on the front wing.

Lightness:

• The weight of the foils has been significantly reduced (e.g., 40g less on the fuselage, 700g less on a Sirus), making transport easier and also improving responsiveness on the water.

Rigidity and durability:

• The new ovoid section of the fuselage improves rigidity by 30% compared to square versions. This ensures greater stability, especially at high speeds or during rapid transitions.
• The rounded design of the connections between flat surfaces reduces stress points, significantly increasing break resistance by 30%.
• Materials such as reinforced aluminum for the fuselage and carbon for the wings offer an excellent weight-to-rigidity ratio.

Glide and lift performance:

• Thanks to a constant profile on the front wings, lift is enhanced, allowing for a 200 cm² reduction in wing size while maintaining the same lift as a larger wing from the V2 version.
• The V3 wings are designed to minimize drag and maximize glide, a major focus of their development.
• V3 wings offer much greater tolerance, making flight easier even at low speeds. They no longer stall abruptly when approaching the surface or when a tip emerges.

Choosing the ideal foil can quickly become complex with the numerous parameters to consider. Size, surface area, ratio, thickness, profile... These are all characteristics that influence glide, lift, and maneuverability. In this guide, we break down the essential elements to help you make the right choice.

Surface Area of the Front Wing

The surface area of the front wing is crucial for determining lift, speed, and maneuverability. Generally, a larger wing is more stable and offers better low-speed lift, making it ideal for beginners and light wind conditions. On the other hand, a smaller wing favors speed and maneuverability but requires more experience.

• Large Surface: Ideal for light wind, beginners, and riders looking for prolonged glide and high stability.
• Small Surface: Perfect for waveriding, racing, and freestyle, offering enhanced responsiveness for quick, dynamic maneuvers.

Aspect Ratio

The aspect ratio (the ratio between wingspan and surface area) directly influences stability, glide, and maneuverability. A high aspect ratio provides better glide and higher top speed, but may make the foil more technical to handle, whereas a moderate ratio improves control and tolerance. A low aspect ratio will be very forgiving but slower.

• Low Ratio (less than 6): For beginners seeking safety with a simple, tolerant foil.
• Moderate Ratio (6 to 9): A good compromise between maneuverability, smooth glide, and stability, ideal for freeride, surfing, freestyle, and varied conditions.
• High Ratio (9 to 12): For glide and speed, suitable for lightwind, downwind, and racing.
• Extreme Ratio (over 13): For pumping and maximum glide with minimal energy.

Types of Front Wing Outlines

Rectangular Outline

• Characteristics: Offers moderate wingspan and even surface distribution.
• Advantages: Very stable due to surface being spread evenly; offers predictable lift. Ideal for beginners and those seeking stability.
• Disadvantages: Less maneuverable and harder to react in tight turns; higher drag limits speed and glide.

Tapered Outline

• Characteristics: Diamond-shaped surface, concentrated at the center and tapering off towards the tips.
• Advantages: More maneuverable in turns, as the reduced surface at the tips helps change direction; lower drag for better glide.
• Disadvantages: Less stable due to smaller tips, requiring more technical control; sometimes abrupt behavior.

Elliptical Outline

• Characteristics: Surface is concentrated at the center, tapering smoothly to the tips.
• Advantages: More maneuverable in turns with smooth tip reduction, helping controlled direction changes; lower drag.
• Disadvantages: Less stable due to smaller tips, requiring more technical control; less glide due to significant cord length at the wing's span.

Crescent Outline

• Characteristics: Curved surface tapering toward the rear, with the lift concentrated at the center.
• Advantages: More stable and progressive in turns due to the rearward lift; smoother glide.
• Disadvantages: Less responsive.

Football Outline

• Characteristics: Surface concentrated at the tips with reduced center chord.
• Advantages: Ultimate lateral stability.
• Disadvantages: Poor maneuverability; significant mechanical stresses causing flex and torsion; risk of cavitation and abrupt turns.

Dihedral of the Front Wing

The front wing’s curve when viewed from the front is called the dihedral. This refers to the angle at which the two halves of the wing are tilted relative to the horizontal axis. Depending on this tilt, we talk about:

• Neutral Dihedral: Flat wing with no upward or downward inclination. Provides uniform lift and constant stability.
• Positive Dihedral: Tips are lifted upward, which increases lateral maneuverability and responsiveness without reducing lift.
• Negative Dihedral (Anhedral): Tips are downward, promoting stability in turns by keeping the tips engaged in the water, though this can reduce lift.

The dihedral plays a key role in lift, stability, grip, and maneuverability. The curvature of the tips is part of the dihedral, but it’s the central curvature that primarily defines the wing’s character. A negative dihedral is more grippy but can be made more maneuverable with positive tips or snappier with flat tips.

Detailed Dihedral Types

Flat Dihedral

• Characteristics: The wing is mostly flat with no significant upward or downward curve.
• Advantages: Provides regular, predictable lift and stable glide. Ideal for speed and flat or aerial maneuvers.
• Disadvantages: Less stable in sharp turns, as the lack of curvature reduces lateral engagement in water.

Lowered Dihedral

• Characteristics: The wing’s halves tilt downward, creating a descending shape at the center.
• Advantages: Better grip in the water during turns and reduces vibrations in choppy waters.
• Disadvantages: Reduces glide due to extra drag and less lift from the surface area.

Raised Dihedral

• Characteristics: The wing’s halves tilt upwards, forming a gentle upward curve.
• Advantages: Increases rail-to-rail movement, making the foil very maneuverable and reduces the behavior anomalies, supporting better glide.
• Disadvantages: Less control, particularly in chop and at high speeds. More demanding, suitable for advanced riders.

Seagull Wing Dihedral

• Characteristics: The wing takes on a double curve downward at the center, similar to a seagull's wings.
• Advantages: Significant stability, making the foil very stable and easy to control in flight.
• Disadvantages: Increased drag at high speeds, limiting glide and top speed.

Front Wing Tips

The curvature of the front wing tips influences overall lift, stability, grip, and maneuverability. The curvature of the tips is part of the dihedral, but it’s the central curvature that defines the wing’s character.

Flat Tips

• Characteristics: Tips are aligned without curvature.
• Advantages: Provides regular and stable lift, making the foil easy to control in straight lines and during takeoff, with predictable turns.
• Disadvantages: Less forgiving during steep angles; tips can cause a loss of lift.

Lowered Tips (Negative Dihedral)

• Characteristics: Tips are angled downward, further from the water surface.
• Advantages: Enhances grip in turns, increasing control in sharp turns or choppy conditions.
• Disadvantages: Increased drag, limiting glide and top speed.

Raised Tips (Positive Dihedral)

• Characteristics: Tips curve upward.
• Advantages: Increases maneuverability, especially in rail-to-rail transitions, and helps the foil lift a tip out of the water for slashing moves.
• Disadvantages: Requires tolerant profiles due to frequent "tip out" situations and can be dangerous when falling.

Wing Profile

The thickness and shape of the wing’s profile play a major role in lift and behavior:

• Thick Profile: Generates more lift at low speeds, offering more tolerance, making takeoffs easier, ideal for beginners and lightwind.
• Thin Profile: Reduces drag, offering faster glide and better control at high speeds, preferred for waveriding and racing.

Extrados vs Intrados

• Extrados Voluminous: High lift and tolerance, but low speed.
• Intrados Voluminous: Excellent glide with less lift.

Leading Edge Types

• Round Leading Edge: Great tolerance for all angles.
• Pinched Leading Edge: Fast but unstable, less forgiving.

Rear Section Profile

• Extrados Hollow: Fast, but less forgiving.
• Intrados Hollow: High lift but limited glide.

Fuselage Type

The shape and length of the fuselage influence stability and responsiveness:

• Long Fuselage: Offers better stability and is easier to control, ideal for beginners, lightwind, freeride, and glide sessions.
• Short Fuselage: More playful and dynamic, ideal for freestyle and radical surfing. Also useful for speed with quick corrections under load.

The GONG V3 foils, with their optimized designs, offer superior lift and glide, allowing for a reduction in wing surface area by approximately 200 cm² compared to V2 models. Below are recommendations tailored to different skill levels and riding styles:

Beginners

For learning to foil, a front wing with sufficient surface area is essential for maintaining flight and enabling early takeoff, especially at low speeds. Beginners should prioritize larger surface areas for maximum stability and forgiveness. With V3 models, wings between 1,300 to 1,800 cm² are ideal, depending on weight and preferences.

Recommended sizes by weight:

• 70 kg rider: Front wing of 1,300 to 1,500 cm² for stability and easy takeoff.
• 85 kg rider: Front wing of 1,500 to 1,700 cm² for added lift and comfort.
• 100 kg rider: Front wing of 1,700 to 1,800 cm² to maximize takeoff and tolerance.

Intermediate / Advanced Riders

For more experienced riders, the choice of wing size depends on the primary goal: comfort, responsiveness, lightwind performance, or glide for freefly and downwind sessions.

Comfort and Stability

Select a front wing that balances lift and maneuverability. Wings between 1,100 to 1,400 cm² ensure early takeoff with good flight stability.

• Example: An 80 kg rider might choose a 1,200 cm² wing for a comfortable and versatile setup.

Responsiveness

For a more dynamic riding style, wings between 900 and 1,200 cm² are ideal. This smaller surface reduces drag, providing more reactive handling, but requires good technical skills to maintain control.

• Example: An 80 kg rider using a 1,000 cm² wing will enjoy increased maneuverability, though takeoff may demand more effort.

Lightwind Performance

In light wind conditions, larger wings (about 1,200 to 1,600 cm² for V3 foils) ensure sustained flight even with minimal energy. The Sirus V3 is highly recommended for maximizing lift at very low speeds, making it perfect for lightwind sessions.

Glide for Freefly / Downwind

Advanced riders seeking maximum glide for downwind or freefly sessions should choose high-aspect-ratio wings, typically between 1,000 and 1,200 cm² for V3 models. These wings optimize continuous speed and glide but require advanced technical skills.
