Duotone Mast Slim 2.0 D/LAB 2025 – Ultimate High-Performance Foil Mast for Speed and Precision

The Duotone Mast Slim 2.0 D/LAB 2025 is a premium high-modulus carbon foil mast engineered for riders who demand maximum efficiency, rigidity, and control across disciplines like hydrofoil surf wing, wing foiling, foil surfing, and wind foiling. Designed as Duotone’s most advanced mast to date, it delivers exceptional hydrodynamics, ultra-low drag, and precise responsiveness, making it a top-tier upgrade for serious foilers.

Built with cutting-edge materials and a refined aerodynamic profile, this mast is optimized for high-speed riding, smooth carving, and efficient pumping, ensuring peak performance in all conditions.

Revolutionary Slim Design for Maximum Efficiency

The Mast Slim 2.0 D/LAB stands out with its ultra-thin profile, specifically engineered to minimize drag and maximize glide. This slim design allows riders to accelerate faster and maintain speed with less effort.

The mast’s tapered chord length and thickness are carefully optimized to deliver the perfect balance between strength and reduced resistance.

Key advantages of the slim profile:

• Reduced drag for higher top speeds
• Smoother water flow and improved glide
• Faster acceleration and take-off
• Enhanced efficiency during pumping

This design makes it particularly effective for high-performance wing foil and foil surfing sessions where speed and efficiency are critical.

High Modulus Carbon Construction for Ultimate Stiffness

At the core of the Mast Slim 2.0 D/LAB is its high modulus (HM) carbon construction. This advanced material ensures exceptional stiffness, allowing for direct power transfer and precise control.

Each mast is engineered with optimized fiber orientation to maximize both bending and torsional rigidity.

Benefits of HM carbon construction:

• Instant response to rider input
• Increased stability at high speeds
• Enhanced control in choppy conditions
• Superior durability and structural integrity

This results in a mast that feels incredibly solid underfoot, giving riders confidence to push their limits in wind foiling and aggressive carving scenarios.

Monobloc Design for Maximum Performance

The Mast Slim 2.0 D/LAB features a full monobloc (one-piece) construction, eliminating weak points and enhancing overall stiffness.

Monobloc advantages:

• Increased torsional rigidity
• Improved durability
• Direct energy transfer
• Consistent performance under load

This construction ensures that all rider input is efficiently transferred into motion, improving responsiveness and control across all foiling disciplines.

Drag-Optimized Base Plate for Smooth Take-Offs

A key innovation in this mast is its redesigned base plate, which is optimized to reduce drag during critical phases such as take-off, touchdowns, and landings.

Base plate improvements:

• Reduced resistance during water starts
• Smoother touchdowns and recoveries
• Improved pumping efficiency

This feature allows riders to get on foil quicker and maintain momentum more easily, especially in lighter wind conditions or during technical maneuvers.

Playful Turning and Precision Control

Despite its high stiffness, the Mast Slim 2.0 D/LAB maintains a playful and responsive turning character. This balance between rigidity and maneuverability makes it suitable for both carving and freestyle.

Turning performance highlights:

• Smooth and precise carving
• Quick directional changes
• Enhanced control in waves
• Aggressive pop for freestyle moves

The mast’s design ensures that riders can execute tight turns and dynamic maneuvers with confidence in hydrofoil surf wing and wing foiling sessions.

Ventilation Resistance for Consistent Performance

Another major advantage of the Mast Slim 2.0 D/LAB is its high resistance to ventilation. This means the mast maintains consistent performance even at higher speeds or when riding close to the surface.

Benefits of ventilation resistance:

• Smooth and uninterrupted ride
• Reduced risk of sudden loss of lift
• Greater confidence at speed

This is especially important for advanced riders pushing performance boundaries in challenging conditions.

Size-Specific Optimization for Every Discipline

Each size of the Mast Slim 2.0 D/LAB is individually designed to suit specific riding styles and conditions, ensuring optimal performance across disciplines.

Available sizes and use cases:

• 76 cm – Ideal for prone foiling and downwind riding
• 84 cm – Perfect all-round size for wing foiling and freeride
• 94 cm – Designed for freerace and high-speed performance

This tailored approach ensures that riders can choose the perfect mast length for their specific needs.
