Mast HD SDM C75 Constant Curve 520cm Unifiber UF006210520

Description: The Unifiber Mast HD SDM C75 Constant Curve 520cm is a high-performance windsurf mast designed to deliver a balanced blend of durability and responsiveness. Constructed from a C75 carbon composite (approximately 75% carbon) in an SDM (standard diameter mast) profile, this mast gives dependable stiffness through the body with progressive flex toward the tip for controlled power and handling. The Constant Curve profile preserves a classic, even bend favored by many sailmakers, producing predictable draft placement and smooth depowering. Built with heavy-duty reinforcement where loads are highest, the HD C75 is aimed at sailors who want a robust mast that still offers precise feel and acceleration in gusty, wave and freeride conditions. It’s an excellent match for wavesailors, ambitious amateur racers and high-wind freeriders looking to step up performance without sacrificing reliability. Compatible with standard SDM sails and extensions, it integrates easily into common windsurfing rigs.
