Mast HD RDM C75 Constant Curve 340cm Unifiber UF005710340

Description:

The Unifiber Mast HD RDM C75 Constant Curve 340cm is a high-performance reduced-diameter mast designed to deliver a balanced blend of durability and responsiveness for windsurfers. Built around Unifiber’s HD C75 construction, this mast provides a stiff but forgiving feel that suits wavesailors, amateur racers and high‑wind freeriders who want dependable power and control. The Constant Curve profile offers a classic, even bend pattern preferred by many sailmakers, producing predictable sail shape and smooth handling across a wide wind range. As an RDM (Reduced Diameter Mast), it improves feel and connection between rider and sail while maintaining strength for heavy use. The 340 cm length is ideal for many freeride and wave rigs and pairs readily with sails designed for a constant curve mast. For help matching the mast curve to your sail, see Unifiber’s Mast Selector and Windsurf Mast Knowledge pages.
