RRD SWK Carbon Mast 85cm Y27 – Ultra-Stiff Performance Mast for Precision Foiling

The RRD SWK Carbon Mast 85cm Y27 is a premium hydrofoil mast engineered for riders who demand maximum stiffness, speed, and control across disciplines like hydrofoil surf wing, wing foiling, foil surfing, and wind foiling. Designed with cutting-edge carbon technology and refined hydrodynamics, this mast delivers a direct, responsive connection between rider and foil, making it an essential upgrade for performance-focused foilers.

Built for high-speed control and durability, the SWK Carbon Mast Y27 stands out as one of the most advanced mast options in the RRD lineup, offering exceptional rigidity and minimal drag for a smooth and powerful ride.

High-Performance Design for Speed and Control

The SWK Carbon Mast Y27 has been specifically developed to provide superior performance in demanding conditions. Its slimmer profile, reduced by approximately 3mm compared to previous models, significantly lowers drag and enhances top-end speed.

This refined design makes it ideal for riders using smaller, faster front wings or those pushing their limits in powered conditions.

Key performance benefits:

• Increased top speed due to reduced drag
• Enhanced control at high speeds
• Smoother water flow for efficient glide
• Better responsiveness in dynamic riding

This makes it perfectly suited for advanced wing foil riders and high-performance foil surfing sessions.

Ultra-Stiff 100% Carbon Construction

At the core of the SWK Carbon Mast Y27 lies its full carbon construction using high-modulus materials. The mast is built with a combination of unidirectional (UD) and biaxial prepreg carbon fibers to maximize stiffness and durability.

Construction highlights:

• 100% M40 high-modulus carbon fiber
• Optimized fiber orientation for strength
• Minimal flex and torsion for precision control
• High-density foam core for structural integrity

This advanced construction ensures a “locked-in” feel, allowing riders to maintain complete control even at high speeds or during aggressive maneuvers.

Maximum Stiffness for Precision Riding

One of the most critical aspects of any hydrofoil mast is stiffness—and this is where the SWK Carbon Mast excels. The design focuses on eliminating unwanted flex and torsion, providing a direct transfer of energy from rider to foil.

Advantages of high stiffness:

• Immediate response to rider input
• Greater stability during turns
• Improved confidence at speed
• Enhanced control in choppy conditions

The result is a mast that allows riders to feel every movement with precision, making it ideal for technical hydrofoil surf wing riding and advanced wind foiling setups.

Refined Hydrodynamics and Reduced Drag

The slimmer profile of the mast not only improves speed but also enhances hydrodynamic efficiency. With a maximum thickness of around 15 mm, the mast cuts cleanly through the water, minimizing resistance.

Hydrodynamic advantages:

• Reduced drag for faster acceleration
• Cleaner water release for improved glide
• Increased efficiency during long rides

This makes the mast highly effective for downwind runs, long-distance foiling, and high-speed carving sessions.

Reinforced Plate for Strength and Durability

The SWK Carbon Mast Y27 features a redesigned base plate that significantly improves durability and load distribution. This ensures that the mast can withstand high-impact landings and heavy loads without compromising performance.

Plate design benefits:

• Increased structural strength
• Better load distribution across the board
• Enhanced durability for long-term use
• Reliable performance during jumps and tricks

This makes it a dependable choice for riders pushing their limits in freestyle or wave riding.

Multi-Discipline Compatibility

One of the key advantages of the SWK Carbon Mast Y27 is its versatility. It is designed to be compatible with multiple foiling disciplines, making it a flexible option for riders who switch between setups.

Compatible with:

• Wing foiling
• Hydrofoil surf wing setups
• Foil surfing
• Wind foiling
• Kite foiling

Its adaptable design ensures consistent performance across different riding styles and conditions.
