Base SDM V2 U-Pin Unifiber UF030070001

Base SDM V2 U-Pin Unifiber UF030070001

Description:

The Base SDM V2 U-Pin from Unifiber is a compact base cup designed to rig sails that do not require a mast extension, allowing a direct connection between sail and mast for a clean, low-profile setup. The V2 adds an additional pulley to the base for effortless, smooth downhauling and improved control over sail tension. Built for repeated on-water use, the unit combines a reinforced base body with corrosion-resistant hardware and a secure U-pin locking system to hold the mast reliably in place. Its streamlined design reduces clutter at the mast foot and simplifies rigging and derigging, saving time on the beach or at the launch. The improved pulley arrangement reduces friction and effort during downhaul adjustments, delivering better sail trim and consistent performance across conditions. The Base SDM V2 is suitable for riders who want a durable, user-friendly base solution that enhances sail control without adding an extension. Compatible with standard SDM (Standard Diameter Mast) systems and common downhaul lines, it integrates easily into most windsurfing rigs.
