Mast Essentials RDM C50 Constant Curve 400cm Unifiber UF005510400

Description: The Unifiber Mast Essentials RDM C50 Constant Curve 400cm is a durable, entry-level performance mast designed for recreational windsurfing and weekend sailors. Built using pre-preg composite manufacturing with a balanced C50 carbon-to-fiberglass layup, it provides an excellent mix of strength and forgiving flex for heavy use and learning progression. As an RDM (Reduced Diameter Mast), it offers improved handling, easier rigging, and increased durability in the lower sections compared with standard diameter masts. The Constant Curve profile delivers a classic, balanced bend favored by many sailmakers, giving reliable power delivery and predictable feel across a wide range of sails. This mast is ideal for beginners and progressing riders who want a robust, versatile spar that stands up to frequent use without sacrificing performance. Compatible with standard RDM mast bases, extensions and most 400 cm sails, it integrates easily into a recreational rig setup.
