UNION Aluminium Foil Mast – 6061 Aircraft-Grade Aluminium, 50cm, 75cm & 85cm
Overview
Find the right balance of durability, control, and value with the UNION Aluminium Foil Mast. Built from 6061 aircraft-grade aluminium and featuring a refined hydrodynamic profile, this mast is designed to deliver stiffness, predictable handling, and efficient movement through the water.
The UNION connection system is engineered to reduce the fuselage connection's cross-sectional area by 15% compared with the previous design, helping streamline water flow at the connection point. The result is a foil mast designed to provide a connected ride feel across disciplines ranging from prone surfing and downwind foiling to winging and freestyle.
Available in 50cm, 75cm, and 85cm lengths, the UNION Aluminium Mast lets you select a setup suited to your riding style, conditions, and experience.
Key Features & Benefits
-
6061 Aircraft-Grade Aluminium: Durable aluminium construction designed for regular use in demanding water-sports conditions.
-
18mm Profile Specification: The supplier specifies an 18mm aluminium design; confirm the precise measurement reference in the manufacturer's technical documentation.
-
Refined Hydrodynamic Profile: Designed to reduce drag and support smooth, efficient movement through the water.
-
Stiff, Controlled Response: The mast's construction is designed to provide torsional rigidity and predictable feedback during turns and transitions.
-
UNION Connection System: Reduces the fuselage connection's cross-sectional area by a stated 15% compared with the previous design.
-
Three Length Options: Choose a shorter mast for learning and shallow water or a longer mast for greater clearance and a broader range of riding conditions.
-
Versatile Foiling Applications: Suitable for different foiling disciplines when paired with compatible components.
Choose Your Mast Length
| Length | Recommended use | Key consideration |
|---|---|---|
| 50cm | Learning and shallow-water riding | Shorter mast height can make early progression and shallow-water sessions more manageable. |
| 75cm | Prone surfing and downwind riding | A middle-length option for riders seeking a balance between clearance and control. |
| 85cm | Freestyle, freeride, winging, and waves | Greater board-to-foil clearance for a range of conditions and riding styles. |
These are supplier-provided usage recommendations. The best length also depends on water depth, wave conditions, rider experience, board setup, and foil configuration.

Compatibility, Care & Maintenance
Before ordering, confirm that the UNION mast is compatible with your fuselage, foil wings, board mounting system, and required hardware. Different foil systems may use different connection interfaces.
Rinse the mast and connection points with fresh water after use, especially after saltwater sessions. Inspect the mast, fasteners, and connection surfaces regularly for corrosion, damage, or excessive wear. Follow the manufacturer's instructions for assembly, bolt torque, maintenance, and storage.
