DETAILED DESCRIPTION
Extreme Glide, Uncompromising Efficiency
The Razor range is designed for riders seeking a pure, fluid, and connected foiling experience. This high-aspect front wing is built to deliver exceptional glide, high speed, and outstanding performance in prone surf conditions, all while maintaining solid pumping capability.
Power, Flow, and Precision in a Single Profile
Every detail of the Razor's design has been optimized to transform each input into speed and directional control. The result is an ultra-efficient front wing, able to maintain clean and stable water flow even through the most technical transitions. It delivers excellent glide from its high-aspect profile, impressive pumping for its size, great speed and control over distance, and a smooth, fluid response through carves and glides. Pair the WR737/BB with a Blackbird stabilizer and a Sabfoil mast for the ultimate setup, or combine it with Blackbird Back Tail fuselages to use Kraken stabilizers and enjoy maximum modularity.
Blackbird Technology: Engineered to Perform
Hydrodynamic efficiency and reduced drag: The streamlined shape and one-piece construction slice through the water, improving flow and reducing turbulence. Active Lift and trim optimization: This front wing generates extra lift, allowing for earlier take-off and reducing pressure on the rear stabilizer. This results in a flatter, faster, and more balanced ride, even at high speeds. Extreme structural stiffness: The aerospace-inspired fuselage design increases torsional stiffness by over 20% compared to cylindrical fuselages.
Who is it for?
The Razor 737 is for riders seeking maximum performance in surf and carving, prone surf enthusiasts, foilers who want to fly further at high speed with minimal effort, and experienced foilers looking to push their limits in the waves. Its MONOBLOC Full Carbon construction guarantees minimal flex and torsion, delivering smoother transitions, instant feedback and control, and a truly connected ride feel.
