Mast HD SDM C75 Constant Curve 490cm Unifiber UF006210490

Description:

The Unifiber Mast HD SDM C75 Constant Curve 490cm is a high-performance windsurfing mast engineered to deliver a balanced blend of durability and responsive feel for advanced recreational and competitive sailors. Built using Unifiber’s C75 high-carbon composite construction, this SDM (Standard Diameter Mast) provides a predictable, classic constant bend profile that many sailmakers prefer for its versatility across conditions. The HD construction enhances impact resistance and longevity without sacrificing the lively feedback and control required for wavesailing, high-wind freeriding and amateur racing. Its constant curve produces smooth power delivery through the sail, aiding stability and handling when carving, jumping or sailing in gusty winds. The 490 cm length is ideal for larger sails and rigs where a stable, traditional bend is wanted; it is compatible with standard SDM sails and common mast bases. For guidance on matching mast curve and flex to your rig, refer to Unifiber’s Mast Selector and windsurf mast knowledge pages.
