UNION APEX Carbon Foil Mast – 14mm Ultra-Thin Profile, 78cm & 84cm

Overview

Experience precision and efficiency on the water with the UNION APEX Carbon Foil Mast. Built from ultra-high-modulus carbon, the APEX features an exceptionally thin 14 mm profile designed to minimize hydrodynamic drag while maintaining high structural and torsional stiffness.

The streamlined UNION connection reduces the fuselage connection's cross-sectional area by a claimed 15% compared with the previous design, helping improve water flow around this critical connection point. Combined with the mast's stiffness-focused construction, the APEX is designed for responsive handling, efficient glide, and precise feedback through turns.

Available in 78 cm and 84 cm lengths, the UNION APEX lets riders choose a mast suited to their preferred discipline, from prone and downwind foiling to freestyle, freeride, and wave riding.

Compatibility, Care & Maintenance

Before ordering, confirm compatibility with your board mounting system, fuselage, and foil wings. Check the required screw lengths and mounting interface against the manufacturer's instructions; do not assume the included hardware fits every board or foil configuration.

Rinse the mast and mounting hardware with fresh water after saltwater sessions. Inspect the carbon structure, connection surfaces, screws, and T-nuts regularly for damage or wear. Follow the manufacturer's instructions for assembly, bolt torque, maintenance, and storage. Do not use a damaged carbon mast.
