KT Aluminium Mast

KT Aluminium Mast

*Requires mast plate and doodad to complete the mast, sold separately.

The KT Aluminium Mast is a strong, durable and high-precision mast designed for reliability across all foiling disciplines. CNC-machined from 6061-T6 aeronautical-grade aluminium and anodised for saltwater protection, it provides the perfect blend of stiffness, efficiency and long-lasting performance.

At 19 mm thick, the mast has been optimised with a hydrodynamic foil section that allows it to behave like a much slimmer mast once riding speed increases. Above approximately 13 mph, the drag difference between this aluminium mast and the KT Carbon Mast becomes negligible, making it a high-value option for riders wanting dependable performance without the cost of carbon.

Its stiffness offers predictable handling, controlled pitch feedback, and a clean, smooth ride through chop or turbulence — ideal for surf, wing, downwind, wake and SUP foiling.
