Extreme glide, uncompromising efficiency

The Razor line is designed for riders seeking a pure, fluid, and continuous flying experience.
A high-aspect front wing built to deliver exceptional glide, unprecedented pumpability, and outstanding performance in downwind and prone surf conditions.

Power, flow, and precision in a single profile

Every detail of the Razor’s design has been optimized to transform every input into speed and directional control.
The result is an ultra-efficient front wing, capable of maintaining clean and stable water flow even through the most delicate transitions.

Key features

• Infinite glide thanks to the high-aspect profile

• Surprisingly strong pumpability for its size

• Speed and control over long distances

• Smooth, fluid response through carves and glides

This set includes the Blackbird Razor 977, the Progressive Stabilizer 375, and the Blackbird UHM 75 mast.

Blackbird Technology, Built to Perform

Hydrodynamic Efficiency and Reduced Drag
The streamlined shape and monobloc construction cut cleanly through water and air, improving flow, reducing turbulence, and smoothing transitions, touchdowns, and rail-to-rail moves.

Active Lift and Trim Optimization
The wing generates additional lift, enabling earlier takeoff and reducing pressure on the rear stabilizer. The result is a flatter, faster, more balanced ride—even at higher speeds.

Extreme Structural Stiffness
The aerospace-inspired fuselage design increases torsional rigidity by over 20% compared to cylindrical fuselages. Load distribution is optimized to handle hard landings and aggressive maneuvers.

MONOBLOC Full Carbon Construction
The integrated one-piece connection between front wing, fuselage, and tail guarantees:

• Minimal flex and twist

• Smoother transitions

• Instant feedback and control

• A truly connected riding feel

Who it’s made for

• Riders seeking maximum efficiency and glide

• Downwind and prone surf enthusiasts

• Those who want a foil that can fly further with minimal effort

• Experienced foilers looking to push their limits with a high-aspect setup
