Slingshot One-Lock HM Carbon Mast | Ultra-Rigid High-Modulus Carbon Mast

The Slingshot One-Lock HM Carbon Mast is built for riders who want absolute rigidity, clean glide, and precise feedback from their foil. Using high-modulus carbon and Slingshot’s One-Lock connection system, this mast is designed to transfer every input directly into the foil with minimal flex or energy loss.

Whether you’re pushing speed, riding powered conditions, or looking for maximum efficiency in lighter winds, this mast is a clear upgrade over standard carbon and aluminium options.

REAL-WORLD FEEL

Compared to aluminium or standard carbon masts, the HM Carbon Mast feels noticeably more solid under load. At speed, there’s less twist through turns and far more confidence when riding powered-up wings or kites.
If you’re progressing into faster foils, larger wings, or stronger wind, this mast keeps the setup calm and predictable.

FAQs

Is this mast compatible with older Slingshot foil systems?
No. This mast is designed specifically for the One-Lock system and is not compatible with pre–One-Lock fuselages.

Is HM carbon worth it over standard carbon?
If you’re riding faster, heavier wings, or powered conditions, yes. The extra stiffness is immediately noticeable.

Which mast height should I choose?
82cm suits most riders. Choose 72cm for shallow or surf, and 92cm for speed, chop, and advanced riding.
