For who
- Intermediate to advanced foilers
- Riders who want maximum mast stiffness and highly direct feedback
- Those looking to improve foil stability at higher speeds
- Users of the Union platform who need a clean, low-drag mast profile
When to choose
- When you need a mast with very low deflection and precise handling
- When you want improved early lift and long glide efficiency
- Choose 78 cm for prone and downwind riding
- Choose 84 cm for all-round freeride, freestyle and wave conditions
- When you prefer a unified T40 hardware standard across the entire Union setup
Behaviour
The slim 16 mm mast profile significantly reduces drag, improving early takeoff and sustained glide during longer transitions. Its monoblock construction removes flex points, giving the mast immediate response and high stability even under heavy load.
The tapered upper section increases stiffness where forces are highest, while the thin hydrodynamic lower profile keeps drag low and maintains efficient water flow. The mast's shape helps resist ventilation, improving control during dynamic manoeuvres.
Construction & technologies
The Union Carbon Mast is built from high-modulus prepreg carbon, delivering outstanding stiffness-to-weight performance. The monocoque construction improves energy transfer and reduces drag along the entire mast.
A stainless steel 316 integrated insert ensures precise alignment and a rigid connection with the Union interface. The unified T40 screw system simplifies assembly and keeps the entire platform consistent.
The aerodynamic profile enhances high-speed stability, reduces drag and increases overall foil efficiency in a wide range of conditions.
