Mast Essentials RDM C50 Constant FL Curve 400cm — Unifiber (UF005520400)

Description:
The Unifiber Essentials RDM C50 Constant FL 400 cm mast is an entry-level, high-value windsurfing mast engineered for recreational sailors and beginners who want reliable performance without premium cost. Constructed using pre-preg manufacturing and a C50 carbon/fiberglass composite with a lower carbon-to-fiberglass ratio, it delivers excellent durability to withstand frequent use and occasional knocks. The RDM (reduced diameter) profile improves handling, rigging ease and compatibility with modern sails and booms. The Constant FL (flex-top) curve provides a contemporary bend with increased centre flex for a forgiving, well-balanced feel that smooths power delivery and improves sail control. This mast is ideal for weekend warriors and sailing schools thanks to its robust build and predictable response across a range of conditions. Compatible with standard RDM mast bases, extensions and most beginner to intermediate sails, it offers a practical, long-lasting foundation for progressing windsurfers.
