Base RDM V2 U-Pin Unifiber UF030060003

Base RDM V2 U-Pin Unifiber UF030060003

Description:

The Unifiber Base RDM V2 U-Pin is a compact mast base solution designed to rig sails that do not require a mast extension. Its V2 update adds an extra pulley to the base cup, enabling effortless and more controlled downhauling of the sail for precise sail trim. Built for RDM (Reduced Diameter Mast) systems, the U-Pin retention keeps the mast securely seated while allowing quick installation and removal. The unit is constructed from marine-grade components for durability and corrosion resistance in the harsh saltwater environment. Its low-profile design minimizes height and weight at the base of the rig, contributing to improved balance and handling of the board. The added pulley reduces friction on the downhaul line, making adjustments easier and extending the life of running rigging. Overall, this base cup is ideal for sailors who want reliable, low-maintenance rig components that improve sail control and rig setup efficiency.
