Duotone Fuselage Aero AL 3BS 2024 – High-Performance Backbone for Modern Foiling

Precision Engineering for Next-Level Foiling Performance

The Duotone Fuselage Aero AL 3BS 2024 is a cutting-edge component designed to elevate your wing foil, foil surfing, and wind foiling experience. Built as the structural backbone of your hydrofoil setup, this fuselage delivers unmatched stability, responsiveness, and efficiency across multiple disciplines including wingfoiling, foil surf, and surf foils.

Developed using advanced aluminum construction and refined hydrodynamic shaping, this model represents a significant evolution over previous carbon fuselages. It balances durability, performance, and modular compatibility, making it a must-have upgrade for riders pushing the limits of foiling.

Advanced Hydrodynamic Design for Maximum Efficiency

Reduced Drag, Increased Speed

One of the standout innovations of the Aero AL 3BS is its optimized hydrodynamic profile. By switching to aluminum construction, Duotone engineers were able to reduce the fuselage’s cross-section, significantly lowering drag in the water.

This streamlined shape allows riders to glide effortlessly, improving efficiency whether you’re cruising, pumping, or chasing speed in wind foil sessions. The reduced resistance also enhances acceleration, making take-offs smoother and faster.

3BS Stabilizer Slot Technology

The integrated 3BS (Back Stabilizer Slot) system features a recessed stabilizer mount that creates a flush connection between components.

This innovation delivers:

• Improved water flow around the fuselage
• Reduced turbulence and drag
• Enhanced control at higher speeds
• Better energy transfer during pumping

For riders engaged in wingfoil or foil surfing, this translates into smoother rides and more predictable handling.

Lightweight Yet Strong Aluminum Construction

Strength Without Compromise

The Aero AL 3BS fuselage is CNC-machined from high-grade aluminum, offering increased stiffness and durability compared to previous carbon versions.

Despite the material change, the weight increase is minimal—only about 2.5%—while significantly boosting structural integrity.

Benefits of Aluminum Build

• Higher resistance to stress and impacts
• Improved rigidity for precise control
• Longer lifespan in demanding conditions
• Consistent performance across all disciplines

This makes it ideal for aggressive riders in surf foil conditions or those pushing limits in wind foiling.

Optimized Design Features for Performance

Smart Weight Distribution

Strategically placed cut-outs near the front wing mount reduce unnecessary weight without sacrificing strength.

Enhanced Stability

The recessed stabilizer design improves pitch stability, giving riders better balance and smoother transitions—especially important in wing foiling and downwind sessions.

Direct Riding Feel

The increased stiffness of the aluminum structure results in a more connected and responsive feel, allowing precise input and control during carving and pumping.

Multiple Length Options for Every Riding Style

The Duotone Aero AL 3BS is available in four optimized lengths, each tailored to specific riding styles and skill levels.

• Wing foil freeride and freestyle
• Foil surfing in waves
• Wingfoiling progression sessions
• Wind foiling for speed and control
• Foil surf pumping and carving
• Downwind SUP foiling

Its adaptability makes it one of the most versatile fuselages on the market, suitable for beginners to advanced riders.
