Mast HD SDM C75 Constant FH Curve 400cm Unifiber UF006330400

Description: The Unifiber HD SDM C75 Constant FH Curve 400 cm mast is a high-performance windsurfing mast engineered to deliver a refined balance of durability and responsiveness. Built using Unifiber’s HD C75 carbon composite construction, this SDM (Standard Diameter Mast) provides a stiff, durable backbone with enough measured flex in the top to generate a fluent, powerful sail shape. The Constant FH bend profile flexes in the top similarly to the Green Curve while remaining slightly stiffer in the center, producing predictable handling, clean power delivery and smooth depower through gusts. This mast is ideal for wavesailors, amateur racers and high-wind freeriders who want strong responsiveness without sacrificing robustness in demanding conditions. Its construction and curve profile make it highly compatible with SDM sails and standard mast bases, offering easy integration into most wave and freeride rigs. Overall, the HD C75 FH Curve mast helps improve control in high-wind and choppy conditions while maintaining long-term durability for frequent use.

Key Features: - HD C75 carbon composite construction for an optimized strength-to-weight ratio and long-lasting durability - Constant FH bend curve: fluent top flex with a slightly stiffer center for balanced power and control - SDM profile (Standard Diameter Mast) for broad compatibility with SDM-cut sails and standard mast bases - Designed for responsive handling and predictable depower in gusty, high-wind or wave conditions - Robust layup to withstand frequent impacts and aggressive use typical of waves and high-wind freeriding - Smooth bending characteristics favored by many sailmakers for consistent sail shaping - Precise manufacturing tolerances to ensure consistent performance across the mast range - Ideal for sailors stepping up from entry-level gear to performance-focused rigs
