AFS UHM Ultra High Modulus Mast – Ultimate Performance, Stiffness, and Glide for Advanced Foiling

The AFS UHM Ultra High Modulus Mast is a premium hydrofoil mast engineered for elite riders seeking maximum stiffness, reduced drag, and unmatched control in demanding conditions. Built with cutting-edge Ultra High Modulus carbon, this mast is designed to elevate performance across disciplines such as hydrofoil surf wing, wing foiling, foil surfing, and wind foiling.

With a refined profile, ultra-lightweight construction, and advanced connection system, the AFS UHM mast delivers a high-performance riding experience that prioritizes precision, efficiency, and speed.

Ultra High Modulus Carbon Technology Explained

At the core of this mast lies UHM (Ultra High Modulus) carbon fiber—a material known for its exceptional stiffness and strength-to-weight ratio. This advanced carbon construction allows the mast to maintain its shape even under extreme load, ensuring precise control at all times.

Compared to standard carbon, UHM carbon is significantly stiffer, enabling manufacturers to use fewer layers while achieving greater rigidity and lighter weight.

Benefits of UHM carbon construction:

• Superior stiffness for direct energy transfer
• Reduced flex for precise control
• Lightweight performance for improved handling
• Enhanced durability under stress

This results in a mast that feels incredibly responsive, especially during high-speed runs and aggressive maneuvers.

Ultra-Thin Profile for Maximum Glide

One of the standout features of the AFS UHM mast is its ultra-thin profile combined with a reduced chord length. This streamlined design minimizes drag in the water, allowing riders to achieve higher speeds and smoother glide.

AFS has carefully optimized the mast’s shape to balance minimal thickness with structural rigidity, resulting in a foil that feels fast, fluid, and efficient.

Advantages of the thin profile:

• Reduced hydrodynamic drag
• Increased top speed
• Smoother water flow
• Enhanced glide efficiency

Compared to aluminum masts with similar stiffness, which are thicker and heavier, this mast offers a noticeably more refined riding experience.

Exceptional Rigidity and Control

Rigidity is one of the most critical factors in foil performance, and the AFS UHM mast excels in this area. Its multi-layer carbon construction ensures minimal flex, allowing riders to maintain full control even in high-speed or choppy conditions.

Key control benefits:

• Precise steering response
• Stable ride at high speeds
• Improved confidence in turns
• Reduced energy loss

The stiffness also enhances feedback from the foil, giving riders a more connected and intuitive feel during wing foil and foil surfing sessions.

Fuse Link Connection System for Maximum Efficiency

AFS has integrated its innovative Fuse Link connection system into the UHM mast. This conical assembly connects the mast to the fuselage while preserving structural integrity and hydrodynamic efficiency.

Connection system highlights:

• Tapered interface for optimal load distribution
• Increased rigidity between mast and fuselage
• Improved water flow around the connection point
• Easy installation with just two screws

This system reduces turbulence and ensures a seamless transfer of energy, contributing to overall performance gains.

Integrated Plate for Universal Compatibility

The mast features an integrated mounting plate, making it compatible with most foil boards equipped with a US double-rail system.

Compatibility advantages:

• Easy installation on a wide range of boards
• Secure and stable mounting
• Streamlined setup process

This versatility makes it suitable for riders across multiple disciplines, from hydrofoil surf wing setups to wind foiling configurations.

Designed for All Foiling Disciplines

The AFS UHM mast is built to perform across a wide range of foiling activities, offering consistent performance regardless of riding style.

Ideal for:

• Wing foiling progression and performance riding
• Hydrofoil surf wing sessions in waves
• Foil surfing and downwind runs
• Wind foiling in powered conditions
• Kite and SUP foiling

Its adaptability makes it a valuable component for riders who want one mast that excels in multiple environments.

Sizes and Specifications

The mast is available in multiple lengths, each designed to suit different riding conditions and preferences.
