Mast HD RDM C75 Constant FH Curve 430cm Unifiber UF005730430

Mast HD RDM C75 Constant FH Curve 430cm — Unifiber (UF005730430)

Description: The Unifiber HD RDM C75 Constant FH Curve mast (430 cm) is a high-performance windsurfing spar engineered for wavesailors, amateur racers and high‑wind freeriders seeking a responsive and durable mast. Constructed from a high‑density C75 carbon composite and built as an RDM (reduced diameter) section, it delivers an excellent strength‑to‑weight balance and precise flex behavior. The Constant FH curve offers a fluent overall bend with a relatively stiff mid‑section and increased top flex — producing predictable depowering, smooth sail feel and crisp handling in gusty conditions. The HD layup increases impact resistance and longevity, while the RDM profile improves comfort in the rig and reduces torsional twist. This mast pairs well with modern wave and freeride sails designed for RDM masts; use Unifiber’s Mast Selector to confirm optimal curve compatibility for your rig. Overall, the HD C75 Constant FH is ideal for riders who want a reliable, performance‑oriented spar that copes well with demanding surf and high‑wind sessions.
