One-Lock HM Carbon Mast

Slingshot One-Lock HM Carbon Mast

Maximum stiffness, exceptional responsiveness and precision control for high-performance hydrofoiling.

The Slingshot One-Lock HM Carbon Mast is engineered for riders demanding the highest levels of stiffness, efficiency and control from their hydrofoil setup.

Constructed from premium High Modulus Carbon, this performance mast delivers exceptional torsional and longitudinal rigidity, creating an incredibly direct connection between rider and foil. Every adjustment in foot pressure translates into immediate feedback, giving riders greater confidence when carving, accelerating and riding at speed.

Its refined, low-drag profile minimises resistance through the water, while the optimised One-Lock connection ensures a clean, efficient transition between mast and fuselage.

Whether you're pushing your limits in wave riding, chasing efficiency on downwind runs or riding high-aspect foils, the One-Lock HM Carbon Mast is designed to maximise performance without compromising control.

Key Features

• High Modulus Carbon Construction: Exceptional stiffness for precise foil control and immediate rider feedback.

• Optimised Low-Drag Profile: Hydrodynamic shaping reduces resistance and supports efficient glide and higher speeds.

• Superior Torsional Rigidity: Minimises unwanted twisting under load, providing greater stability through powerful turns and transitions.

• One-Lock Connection System: Innovative mechanical connection allows fast, straightforward assembly and disassembly of compatible foil components.

• Tapered Mast Profile: Carefully engineered chord dimensions balance hydrodynamic efficiency with structural stiffness.

• Internal Connection: Streamlined mast-to-fuselage integration helps reduce turbulence and vibration.

• Hand-Finished Trailing Edge: Precision finishing promotes clean water release and smoother performance.

• RTS Board Mounting System: Quick-release mounting technology makes setting up and packing away your foil faster and easier.

Who Is It For?

The Slingshot One-Lock HM Carbon Mast is particularly suited to intermediate and advanced foilers who want the most responsive connection possible between their board and foil.

Its high-stiffness construction makes it an excellent choice for riders using high-aspect front wings, where rigidity and efficient energy transfer are particularly important.

Ideal for:

• Surf foiling and carving

• Downwind foiling

• Wing foiling

• Wake foiling

• High-performance freeride

• Advanced riders prioritising stiffness and precise control

Why Choose the HM Carbon Mast?

For experienced foilers, mast stiffness can significantly influence the feel and precision of a foil setup.

The HM Carbon Mast offers a premium alternative to standard carbon or aluminium masts, particularly for riders who demand greater responsiveness during high-speed riding, aggressive carving and technical manoeuvres.

Combined with Slingshot's One-Lock modular foil system, it delivers high-end performance with the convenience of quick, simplified assembly.
