UHM 15mm Mast

The 15mm Ultra High Modulus (UHM) Mast is engineered for heavier riders (205+ lbs) riding larger wings (900cm²+), or any foiler demanding absolute rigidity, the 15mm UHM Mast delivers maximum stiffness and incredibly predictable handling.

While our 12mm mast is plenty stiff for the majority of riders, the stiffness of the 15mm mast is in another realm. Confirmed by test riders weighing 240lbs+, it is the stiffest mast we’ve ridden. If you’re a rider seeking extreme rigidity and control under heavy loads, this is the mast for you.

To complement this stiffness, our foil section was developed using advanced multi-point optimization code aimed at significantly reducing drag and promoting stability. By carefully designing the pressure distribution, this mast achieves over 40% lower drag compared to standard baseline NACA profiles. It delivers a uniquely efficient low-drag feel with extreme ventilation resistance, giving you the confidence to push harder and ride faster through extreme maneuvers.

Key Performance Features:

  • Next-Level Rigidity: 30% stiffer in bending and 45% stiffer in torsion compared to our 12mm UHM Mast.

  • Optimized Hydrodynamics: Multi-point optimized foil section delivers 40%+ lower drag than standard NACA profiles.

  • Ventilation-Resistant Profile: Carefully designed pressure distribution prevents surface air drawing at high angles of attack and during extreme maneuvers.

  • Moderate Chord Taper: Offers a more locked-in, predictable yaw feel while charging upwind at high speeds or tow foiling.

Construction: Ultra High Modulus with a proprietary layup that goes beyond typical foam core and Toray M40/M60 constructions.
