Duotone Fuselage Aero AL 3BS
Modular Freedom. Maximum Performance.
The Duotone Aero AL 3BS Foil Fuselage is the backbone of your foil setup—redesigned from the ground up to deliver maximum stiffness, hydrodynamic efficiency, and seamless compatibility across Duotone's latest foil systems.
By transitioning to a precision-machined aluminium construction, Duotone has reduced the cross-section to significantly minimize drag while increasing overall strength. The result is a fuselage that offers carbon-like performance—instant power transfer and controlled feedback—with only a minimal 2.5% weight increase over previous carbon models.
Key Features
- 3BS Technology: The Tri-Beam Structure ensures an incredibly direct and stable connection between mast and wings for rock-solid stability.
- Reduced Drag: Refined hydrodynamic profile and slim cross-section for better glide and efficiency across all disciplines.
- Optimized Weight: Features strategic cut-outs at the front wing mount to keep weight to a minimum without sacrificing rigidity.
- Precision Engineering: CNC-machined aluminium with a corrosion-resistant anodized finish for long-term durability.
- Stabilizer Recess: A dedicated recess at the rear allows the stabilizer to sink in, further smoothing water flow.
