Cabrinha Fusion Carbon Hollow Mast MKII – Ultimate Stiffness, Speed, and Precision Control

The Cabrinha Fusion Carbon Hollow Mast MKII is a premium hydrofoil mast engineered for riders who demand uncompromising performance in hydrofoil surf wing, wing foiling, foil surfing, and wind foiling. Designed with cutting-edge carbon construction and advanced hydrodynamics, this mast delivers exceptional stiffness, reduced drag, and direct energy transfer for a high-performance riding experience.

Built as part of Cabrinha’s modular Fusion system, the MKII hollow mast is the backbone of a modern foil setup, providing the rigidity and responsiveness needed to push limits across all foiling disciplines.

High-Performance Carbon Mast for Modern Foiling

The Fusion Carbon Hollow Mast MKII is designed with one goal in mind: maximizing performance through stiffness and efficiency. By focusing on structural rigidity and weight reduction, Cabrinha has created a mast that enhances every aspect of your ride.

Its lightweight carbon build combined with a streamlined profile ensures:

• Faster acceleration
• Improved top-end speed
• Reduced fatigue during long sessions

The mast’s optimized airfoil profile minimizes drag while maintaining strength, allowing riders to glide effortlessly across the water in wing foil and foil surfing sessions.

Hollow Carbon Construction for Maximum Rigidity

At the core of the MKII mast is its innovative hollow carbon construction. Using advanced bladder molding technology, Cabrinha has achieved a structure that maximizes stiffness while minimizing weight.

Key benefits of hollow construction:

• Superior skin compression for increased rigidity
• Reduced overall weight without compromising strength
• Enhanced responsiveness during turns and pumping

This design positions the carbon layers further from the center, significantly improving torsional stiffness and eliminating flex under load. The result is a direct connection between rider input and foil response.

Bladder Molded Technology for Precision Engineering

The Fusion Carbon Hollow Mast MKII uses a sophisticated bladder molding process, ensuring precise carbon layering and consistent structural integrity.

Advantages of this technology:

• Uniform carbon distribution
• Increased structural strength
• Optimized flex characteristics

This construction method also improves flotation and durability, making the mast suitable for demanding conditions in hydrofoil surf wing and wind foiling environments.

Exceptional Stiffness and Energy Transfer

One of the most critical aspects of a foil mast is its stiffness, and the MKII excels in this area. Cabrinha has engineered this mast to provide maximum torsional and bending rigidity.

Performance benefits:

• Instant energy transfer during pumping
• No lag in turns or direction changes
• Increased control at high speeds

By reducing flex, the mast ensures that all rider input is transmitted directly to the front wing, improving efficiency and responsiveness in wing foiling and foil surfing.

Optimized Airfoil for Low Drag Efficiency

The Fusion Carbon Hollow Mast MKII features a carefully designed airfoil profile that balances drag reduction with structural integrity.

Low drag design advantages:

• Higher top speeds
• Smoother glide
• Increased efficiency in all conditions

This optimized shape ensures a low drag-to-stiffness ratio, enabling riders to maintain speed with less effort, even in lighter wind conditions.

TE Scallop for Improved Turning and Control

A standout feature of the MKII mast is its TE (Trailing Edge) scallop design. This innovation enhances both performance and control.

Benefits of TE scallop:

• Improved turning efficiency
• Enhanced maneuverability
• Better balance between stiffness and flexibility

This feature allows riders to experience smoother transitions and more dynamic carving, especially in wave riding and freestyle scenarios.

Integrated High Modulus Mounting Plate

The mast includes a fully integrated high modulus carbon mounting plate, ensuring a strong and seamless connection between the board and foil.

Key advantages:

• Increased structural integrity
• Reduced drag at connection points
• Improved overall system stiffness

This integration eliminates weak points and enhances the durability of the entire foil setup.

Precision Tapered Fit for Seamless Connection

The Fusion system uses a precision tapered fit between the mast and fuselage, improving both performance and usability.

Benefits:

• Maximum rigidity at connection points
• Easy assembly and disassembly
• Enhanced durability

This ensures a tight, secure fit that eliminates unwanted movement and improves overall riding precision.

Technical Specifications

Specifications may vary slightly depending on size.

Available Sizes and Their Use Cases

Choosing the right mast length is essential for optimizing performance in different conditions.

Size recommendations:

• 74 cm – Ideal for beginners and shallow water conditions
• 84 cm – Perfect all-round size for wing foiling and surf foiling
• 94 cm – Best for advanced riders, high speeds, and choppy conditions

These options allow riders to customize their setup based on skill level and riding style.
