Mast HD SDM C75 Constant Curve 400cm Unifiber UF006210400

Description:

The Unifiber Mast HD SDM C75 Constant Curve 400cm is a high-performance windsurfing mast engineered to deliver a blend of durability and responsive handling. Constructed from a high-density C75 carbon composite, this SDM (Standard Diameter Mast) provides the stiffness and energy return that wavesailors, amateur racers, and high-wind freeriders demand. The Constant Curve profile offers a classic, balanced bend preferred by many sailmakers, producing reliable sail shaping and predictable feel across a wide range of conditions. Built for heavy use, the HD construction increases longevity while maintaining dynamic performance for aggressive maneuvers and sustained high-load sailing. Its 400 cm length makes it suitable for a broad array of sails and rigs designed around a constant-curve mast.
