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 turn every input into speed and directional control.
The result is an ultra-efficient front wing, capable of maintaining a clean and stable water flow even through the most delicate transitions.

Infinite glide thanks to the high-aspect profile

Surprising pumpability for its size

Speed and control over long distances

Smooth and fluid response through carves and glides

The Set: This kit includes the Blackbird Razor 977 front wing, the FC/M full carbon modular fuselage, mast 75 Blackbird and the SDW 375 stabilizer.

Blackbird Technology: Built to Perform
Hydrodynamic Efficiency and Drag Reduction The tapered shape and monoblock construction slice through water and air, improving flow and reducing turbulence. This makes transitions, touchdowns, and rail-to-rail maneuvers significantly smoother.

Active Lift and Trim Optimization The wing generates additional lift, enabling earlier take-offs and reducing pressure on the rear stabilizer. The result is a faster, more stable, and balanced ride, even at high speeds.

Extreme Structural Rigidity The fuselage design, inspired by aeronautics, increases torsional stiffness by over 20% compared to cylindrical fuselages. Load distribution is optimized to withstand even the hardest landings or the most aggressive maneuvers.

Full-Carbon Modular Fuselage:

Minimizes flex and torsion.

Allows for testing different stabilizers and perfecting the trim with shims.

Ensures smoother transitions.

Who it’s made for
Ambitious and technical riders

Freestylers looking for pop and control

Downwind and wave riders seeking speed and flow

Anyone who wants a front wing that rides like a natural extension of their body
