Duotone Mast Aluminium 3BS – Versatile Performance Mast for Modern Foiling

The Duotone Mast Aluminium 3BS is engineered to deliver a perfect blend of performance, durability, and versatility for riders across all foiling disciplines. Whether you’re into hydrofoil surf wing, wing foiling, foil surfing, or wind foiling, this mast is designed to provide a stable, efficient, and responsive ride without the premium price of full carbon alternatives.

Built with high-grade aluminium and enhanced by Duotone’s innovative 3BS+ connection system, this mast offers seamless compatibility, excellent stiffness, and long-lasting reliability—making it a cornerstone component in any modern foil setup.

Advanced Aluminium Mast Built for Performance and Value

The Mast AL 3BS sits at the sweet spot between affordability and high performance. While carbon masts are known for their lightweight feel, this aluminium version delivers comparable stiffness and responsiveness at a more accessible price point.

Its carefully engineered profile ensures low drag performance, allowing smooth water flow and efficient gliding across conditions. Riders benefit from a stable and predictable ride, which is essential when progressing in wing foil or exploring higher speeds in wind foiling.

Key advantages:

• Excellent stiffness for precise control
• Strong value compared to carbon masts
• Smooth and efficient glide
• Reliable performance across disciplines

Innovative 3BS+ Connection System

One of the standout features of the Duotone Mast Aluminium 3BS is its 3BS+ connection system, designed to simplify setup while maximizing compatibility across the Duotone foil ecosystem.

This system allows riders to connect seamlessly with:

• Duotone Aero AL 3BS fuselages
• D/LAB foil components
• Compatible Duotone and Fanatic systems

The result is a more streamlined setup process and the flexibility to upgrade components without replacing the entire system.

Benefits of the 3BS+ system:

• Faster assembly and disassembly
• Cross-compatibility with multiple foil setups
• Future-proof design for upgrades

Exceptional Stiffness and Direct Feel

A major strength of this mast is its incredibly stiff and direct ride feel. Unlike cheaper aluminium masts that can feel flexy, the AL 3BS delivers a solid, connected sensation between the rider and the foil.

This translates into:

• Immediate feedback underfoot
• Improved control during turns
• Greater confidence at speed

The stiffness also enhances performance in dynamic conditions such as wave riding or freestyle sessions in foil surfing and hydrofoil surf wing disciplines.

Low Drag Profile for Efficient Riding

The hydrodynamic shape of the mast minimizes resistance in the water, allowing riders to maintain speed with less effort. This is particularly important for pumping efficiency and long glides.

Low drag benefits:

• Increased speed potential
• Reduced fatigue during long sessions
• Smoother ride in choppy water

This efficient design helps riders stay on foil longer, making it ideal for progression in wing foiling and downwind adventures.

Durable Construction for Long-Term Use

Durability is a key focus of the Mast AL 3BS. Constructed from aerospace-grade aluminium, it is built to withstand daily use, travel, and impacts better than many lightweight alternatives.

Durability features:

• High-wall base plate for strong board connection
• Helicoil threaded inserts for long-lasting screw fittings
• Corrosion-resistant materials for marine environments

The base plate creates a “one-piece feel,” improving structural integrity and ensuring consistent performance over time.

Multiple Sizes for Every Foiling Condition

The Mast AL 3BS is available in four different lengths, allowing riders to fine-tune their setup based on skill level, water conditions, and riding style.

Available sizes:

• 60 cm – Ideal for shallow water and pump foiling
• 75 cm – Great for beginners and flat water
• 82 cm – Best all-round size for most riders
• 90 cm – Perfect for rough water and advanced riding

Each size offers a unique balance of stability, maneuverability, and clearance, ensuring optimal performance in various wing foil and foil surfing environments.
