Sabfoil Kit Leviathan Blackbird – Ultimate High-Aspect Foil System for Infinite Glide

The Sabfoil Kit Leviathan Blackbird is a premium full-carbon hydrofoil system engineered for riders seeking unmatched glide, pumping efficiency, and long-distance performance. Built around Sabfoil’s advanced Blackbird technology, this kit is designed for high-level hydrofoil surf wing, wing foiling, foil surfing, and wind foiling disciplines where efficiency and control are critical.

Combining cutting-edge hydrodynamics with a modular carbon construction, the Leviathan Blackbird delivers a smooth, fast, and “endless flight” sensation that redefines what’s possible on the water.

Designed for Perpetual Glide and Efficiency

At the heart of the Leviathan Blackbird kit is a high-aspect front wing (commonly “THE 1350” or 1400 variants), designed to maximize glide and reduce drag. This allows riders to maintain flight with minimal effort, making it ideal for long pump sessions, downwind runs, and low-wind conditions.

The system is specifically tuned to deliver:

• Exceptional glide across flat water and swell
• Low take-off speeds around 7–9 knots
• Extended flight time between pumps
• Efficient forward momentum with minimal drag

This makes it one of the most efficient setups for riders chasing distance and endurance in wing foil and foil surfing sessions.

High-Aspect Front Wing for Maximum Performance

The defining feature of the Leviathan Blackbird is its high-aspect front wing design. With a large span (around 1350 mm for the 1350 version), it delivers massive lift while maintaining a surprisingly fast and efficient profile.

Key front wing benefits:

• Early lift and easy take-off
• Stable flight at low speeds
• High glide ratio for long-distance riding
• Improved efficiency for pumping

Despite its size, the refined profile ensures that the wing remains fast and responsive, avoiding the sluggish feel often associated with large foils.

Active-Lift Technology for Effortless Flight

A standout innovation in the Blackbird range is the Active-Lift system, which integrates lift generation into the fuselage and wing design.

Advantages of Active-Lift:

• Lower stall speed for easier recovery
• “Weightless” sensation underfoot
• Improved forgiveness during missed pumps
• Enhanced control during take-off

This technology allows riders to maintain flight even after imperfect technique, making it highly valuable in real-world conditions where consistency is key.

Modular Full Carbon Construction

The Leviathan Blackbird kit features a fully modular carbon system, allowing riders to fine-tune their setup for different conditions and riding styles.

Construction highlights:

• Full carbon fuselage for stiffness and durability
• Modular back tail system for customization
• High-modulus mast for direct power transfer
• Lightweight design for improved responsiveness

The modular design enables riders to swap stabilizers and adjust angles using shims, offering precise control over performance characteristics.

Low Drag Stabilizer for Speed and Control

The kit includes a specially designed stabilizer (such as the 325 or SDW375 depending on configuration), optimized for low drag and high efficiency.

Stabilizer performance benefits:

• Reduced resistance for higher speeds
• Smooth rail-to-rail transitions
• Balanced pitch stability
• Enhanced pumping efficiency

This allows the foil to maintain speed while remaining agile, making it suitable for both carving and long-distance gliding.

Exceptional Pumping and Downwind Performance

The Leviathan Blackbird excels in pumping and downwind disciplines, where efficiency and glide are critical.

Performance advantages:

• High cadence pumping with less effort
• Ability to connect multiple swells
• Long-distance glide without losing speed
• Stable ride in variable conditions

Its design minimizes vertical oscillation and maximizes forward drive, helping riders maintain momentum across long distances.
