Mast HD RDM C75 Constant FH Curve 400cm Unifiber UF005730400

Mast HD RDM C75 Constant FH Curve 400cm — Unifiber (SKU: UF005730400)

Description: The Unifiber HD RDM C75 Constant FH Curve 400cm mast is a high-performance windsurfing mast designed to deliver a balanced blend of responsiveness and durability for advanced recreational sailors, wavesailors and amateur racers. Constructed in Unifiber’s C75 carbon composite and specified as an RDM (reduced diameter mast), it provides precise sail shaping with lower overall weight and improved handling compared with larger-diameter mast sections. The Constant FH bend curve gives a fluent profile with a flexible top and a slightly stiffer mid-section, producing predictable power delivery and smooth depowering in gusts. Built for repeated high-load use, the HD (heavy duty) construction increases impact resistance and longevity while retaining the performance feel required for aggressive maneuvers and high-wind freeride sessions. Its consistent curve and compatibility with modern sail designs make it a versatile choice for sailors stepping up performance without sacrificing reliability. This mast pairs readily with most RDM-ready sails and standard base/furler fittings; check mast length and manufacturer recommendations for optimal rig matching.

Key Features: - C75 carbon composite construction for a high strength-to-weight ratio and responsive feel - RDM (reduced diameter mast) profile for improved handling and lower swing weight - Constant FH bend curve: flexible top with a stiffer centre for a fluent, controlled curve - HD (heavy duty) layup for enhanced durability and impact resistance in demanding conditions - Precise sail shaping and consistent power delivery ideal for wavesailing, racing & high-wind freeride - Reliable compatibility with RDM-compatible sails and standard mast bases - Smooth depowering characteristics that improve control in gusty or choppy conditions
