The Naish Jet HA Foil 840 Plane 2024 is a high-performance hydrofoil front wing designed to deliver exceptional glide, speed, and maneuverability across multiple disciplines including wing foil, wing foiling, foil surfing, wind foiling, and hydrofoil surf wing riding. Built using advanced high-aspect design principles, this foil is engineered for riders seeking efficiency, control, and versatility in all conditions.

With a refined profile and cutting-edge construction, the 840 size strikes the perfect balance between lift, speed, and control—making it a go-to option for intermediate to expert riders progressing in wingfoil and advanced foiling techniques.

High aspect design for maximum efficiency and glide

The Jet HA 840 belongs to Naish’s high aspect foil range, specifically designed to maximize glide efficiency while maintaining excellent maneuverability. High aspect foils are known for their longer wingspan and narrower chord, which significantly reduce drag and increase glide performance.

The 840 model features an optimized aspect ratio of approximately 9.8, delivering a perfect mix of speed and lift.

Key advantages of the high aspect shape

• Increased glide for longer rides and less pumping effort
• Higher top-end speed for dynamic riding
• Efficient lift generation even at lower speeds
• Improved stability in open water and swell

This makes it an excellent choice for foil surfing and long gliding sessions in wing foiling conditions.

Engineered for performance across multiple disciplines

One of the standout features of the Naish Jet HA 840 is its versatility. It is designed to perform seamlessly across different foiling disciplines.

Compatible riding styles

• Wing foil sessions in light to medium wind

• Pump foiling and freeride

According to product specifications, the Jet HA range is optimized for wing, prone, kite, windsurf, and SUP use, making it one of the most versatile hydrofoil surf wing options available.

Advanced hydrodynamic design features

Naish has refined every aspect of the Jet HA 840 to enhance performance on the water. The foil incorporates several advanced hydrodynamic innovations.

Design highlights

• Increased leading edge area for improved lift and smoother take-off
• Narrow foil section to reduce drag and improve glide
• Strategically shaped wing tips for better turning and pumping
• Slight rake angle to enhance control and lift during turns

These design elements combine to create a foil that “offers exceptional speed, pumping efficiency, and turning ability,” resulting in unmatched maneuverability in the high-aspect category.

Smooth lift and controlled turning performance

One of the defining characteristics of the Jet HA 840 is its smooth and predictable lift. Riders benefit from a progressive lift curve that makes take-offs easier and more controlled.

On-water performance characteristics

• Early and smooth lift-off
• Stable flight even in choppy conditions
• Tight and responsive carving
• Excellent glide between waves

Rider feedback highlights that the 840 “glides really well and lifts smooth, even at low speeds,” making it ideal for both waves and downwind riding.

Premium carbon construction for durability and lightweight feel

The Naish Jet HA 840 is built using high-end materials to ensure both strength and weight reduction.

Construction features

• 100% prepreg 3K carbon outer layer
• Dual expansion core construction
• UD carbon and glass laminate reinforcement
• Satin finish for reduced drag

This construction ensures a lightweight yet durable foil that maintains stiffness under load, providing maximum responsiveness during aggressive wingfoil maneuvers.
