Aluminium Mast Extension SDM V2 U-Pin 45cm Unifiber UF030070050

Description:

The Unifiber Aluminium Mast Extension SDM V2 (45 cm) is a robust, no-nonsense mast extension designed to deliver precise sail tuning and reliable performance for windsurfers of all levels. Constructed from a tough aluminium tube with an upgraded high-strength nylon base, the V2 improves downhauling ease and resists wear in the critical base area. The unit features a rugged double-pin adjustment collar and a U-pin locking system that provides secure, tool-free length setting and confidence under load. Its combination of stiff aluminium and reinforced nylon reduces unwanted flex for better power transfer and more consistent sail feel. Built for frequent use and harsher conditions, the V2 offers long-term durability while remaining straightforward to rig and adjust on the water. Compatible with standard SDM systems, it pairs seamlessly with most SDM booms and Unifiber clamp hardware for a complete, reliable setup.
