Mast HD RDM C75 Constant Curve 430cm — Unifiber
SKU: UF005710430

Description:
The Unifiber HD RDM C75 Constant Curve 430cm mast blends durability and responsiveness for high-performance windsurfing across a range of disciplines. Built on Unifiber’s HD C75 platform, the mast delivers a balanced, classic constant curve favored by many sailmakers for consistent sail shaping and predictable handling. Its RDM (reduced diameter) profile improves torsional control and reduces weight while maintaining strength, making it well suited to wavesailors, amateur racers and high-wind freeriders looking to step up their rig performance. The construction emphasizes longevity and fatigue resistance so the mast keeps its bend characteristics even after repeated use in demanding conditions. Because it follows a classic constant curve, this mast pairs especially well with sails designed for smooth, reliable power delivery and easy tuning. Compatible with standard RDM booms, bases and constant-curve sail designs, it’s a versatile choice for sailors wanting a durable, all-around performance mast.

Key Features:
- HD C75 composite construction for a high carbon-content balance of stiffness, responsiveness and durability
- RDM (Reduced Diameter Mast) profile for improved handling, lower weight and better torsional control
