Mast Essentials SDM C50 Constant FH Curve 490cm Unifiber UF006030490

Description:

The Unifiber Mast Essentials SDM C50 Constant FH Curve 490cm is an entry-level to intermediate windsurfing mast designed to deliver reliable performance with excellent durability. Built using pre-preg manufacturing and a balanced carbon-to-fiberglass layup (C50), this mast provides a forgiving yet responsive feel ideal for recreational sailors, beginners and weekend warriors. The SDM (Standard Diameter Mast) profile fits a wide range of SDM-sleeved sails and is easy to rig and handle. The Constant FH bend curve flexes in the top like the Green Curve but remains a touch stiffer through the center, producing a fluent, controlled shape that suits modern freeride and beginner sails. Robust construction and a slightly lower carbon content improve resistance to heavy use and repeated impacts — perfect for school and rental use as well as personal recreational rigs. Compatible with standard SDM mast bases and extensions, it pairs well with Unifiber sails and recommended mast curves selected via Unifiber’s Mast Selector.

Key Features:

• Pre-preg composite construction for consistent layup and quality control
• C50 layup: balanced carbon-to-fiberglass ratio for durability and predictable flex
• SDM (Standard Diameter Mast) for broad sail compatibility and simple rigging
• Constant FH curve — fluent top flex with a stiffer mid-section for controlled shaping
• 490 cm length suited to medium-to-large sail sizes used in freeride and recreational rigs
• Designed for heavy use and longevity — ideal for rental fleets and weekend sailors
• Forgiving bend characteristics that aid learning and reduce equipment snappage
• Easy pairing with standard mast extensions, bases and SDM-sleeved sails
• Cost-effective entry to Unifiber’s high-end mast family — strong performance/value balance
