Slingshot One-Lock HM Carbon Mast – Ultimate Stiffness and Precision for High-Performance Foiling

The Slingshot One-Lock HM Carbon Mast is engineered for riders who demand uncompromising stiffness, direct feedback, and high-speed efficiency in every session. Designed as part of Slingshot’s innovative One-Lock foil ecosystem, this premium mast delivers elite-level performance across disciplines such as hydrofoil surf wing, wing foiling, foil surfing, and wind foiling.

Built with high modulus carbon and precision-tuned hydrodynamics, the HM Carbon Mast offers a direct connection between rider and foil, unlocking unmatched control, responsiveness, and speed on the water.

High Modulus Carbon Construction for Maximum Stiffness

At the core of the One-Lock HM Carbon Mast is its advanced high modulus (HM) carbon construction. This material is specifically chosen to maximize stiffness and minimize flex, giving riders an incredibly direct and responsive ride feel.

Unlike standard carbon or aluminum masts, the HM carbon layup increases both bending and torsional rigidity. This ensures that every input—whether carving, pumping, or accelerating—is transmitted instantly to the foil.

Key construction benefits:

• Exceptional rigidity for precise control
• Minimal flex even at high speeds
• Enhanced torsional stiffness for better turning accuracy
• Direct feedback for advanced riders

This construction is specifically targeted at performance-focused riders who prioritize stiffness above all else.

Direct Connection and Instant Response

One of the standout features of this mast is the “connected” feel it delivers. The stiffness of the HM carbon eliminates lag between rider input and foil reaction, resulting in instantaneous response.

Performance advantages:

• Immediate reaction during turns and transitions
• Increased confidence at high speeds
• Enhanced control in technical maneuvers

This direct connection is particularly noticeable in high-performance wing foil and foil surfing sessions, where precision and timing are critical.

The result is a more intuitive riding experience that allows advanced riders to push boundaries with confidence.

Low Drag Profile for Speed and Efficiency

The One-Lock HM Carbon Mast features a refined low-drag profile designed to improve hydrodynamic efficiency. Its streamlined shape reduces resistance in the water, allowing riders to achieve higher speeds with less effort.

Low drag design highlights:

• Tapered chord profile for optimal water flow
• Clean connection between components
• Reduced turbulence for smoother glide

This efficient design helps maintain speed across a wide range of conditions, making it ideal for wind foiling and fast wing foiling runs.

Advanced Hydrodynamics and Tapered Geometry

The mast’s geometry is carefully engineered to balance stiffness and efficiency. It features a tapered chord design, widening toward the base to improve structural strength while maintaining a streamlined upper section.

Design characteristics:

• Chord taper from approximately 118 mm to 145 mm
• Optimized carbon placement for strength and weight balance
• Hollow core construction for reduced weight and increased stiffness

This combination ensures that the mast performs efficiently at both low and high speeds, offering versatility across multiple foiling disciplines.

One-Lock System Integration

The HM Carbon Mast is fully integrated into the One-Lock system, offering a seamless and efficient connection between components.

One-Lock system benefits:

• Tool-less assembly and disassembly
• Internal connection for smooth water flow
• Reduced drag between mast, fuselage, and wings
• Faster setup and breakdown time

This system enhances both convenience and performance, making it easier for riders to focus on their session rather than equipment setup.

Precision Finish for Smooth Water Release

Attention to detail is evident in the mast’s hand-finished trailing edge. This refinement improves water release and reduces drag, contributing to a smoother and faster ride.

Finishing features:

• Hand-tuned trailing edge
• Reduced turbulence
• Improved glide efficiency

These subtle improvements make a noticeable difference, especially for riders chasing maximum performance in hydrofoil surf wing and foil surfing conditions.

Versatility Across Foiling Disciplines

The Slingshot One-Lock HM Carbon Mast is designed to perform across a wide range of foiling styles.

Ideal for:

• Wing foiling progression and advanced riding
• Hydrofoil surf wing sessions in waves
• Foil surfing and carving
• Wind foiling at higher speeds
• Downwind and freeride foiling

Its stiffness and efficiency make it particularly well-suited for high-aspect wings and performance-oriented setups.

Available Sizes and Riding Feel

The mast is available in multiple lengths to suit different riding conditions and skill levels.

Size options:

• 72 cm – Best for shallow water and learning environments
• 82 cm – Balanced performance for most riders
• 92 cm – Maximum clearance for chop and waves

Shorter masts offer more stability and easier control, while longer masts provide greater clearance and improved performance in rough conditions.
