Unifiber RDM C75 Carbon Curve FH Mast

The Unifiber RDM C75 Carbon Curve FH Mast is engineered for riders who demand durability, responsive flex, and high-level performance in every windsurf session. Designed with a 75% carbon construction and Reduced Diameter Mast (RDM) profile, this mast delivers a balanced combination of lightweight handling and dependable strength for modern windsurf riding. Whether you enjoy wave sessions, freeride cruising, or advanced sport windsurf setups, this mast is built to elevate your performance on the water.

Built around the Constant FH Curve profile, the mast provides a fluent flex pattern with extra responsiveness in the upper section. This helps modern windsurf sail designs rotate efficiently while maintaining stable power delivery and excellent control during gusts and high-speed runs. The result is smoother acceleration, cleaner sail shaping, and better overall handling for windsurfing enthusiasts.

Built for High Performance Windsurfing

The Unifiber RDM C75 is aimed at riders who want more from their windsurfer sailboard setup without jumping to ultra-expensive 100% carbon race masts. The 75% carbon layup creates a perfect middle ground between lightweight responsiveness and long-term reliability. It reacts quickly during maneuvers while remaining durable enough for demanding windsurf conditions.

For riders practicing aggressive turns, wave riding, or high-wind freeride sailing, the Reduced Diameter design improves grip comfort and impact resistance. RDM constructions are widely preferred by wave and freestyle riders because of their extra strength and improved control during heavy conditions.

Key Features

75% Carbon Construction

The HD C75 construction uses premium carbon materials to produce excellent reflex response while keeping the mast strong and durable. Compared with lower carbon alternatives, the mast reacts faster under load and transfers energy more efficiently into the windsurf sail.

Benefits include:

• Faster sail response
• Improved acceleration
• Better gust absorption
• Reduced overall rig weight
• Enhanced control in rough water

This makes it a strong choice for both intermediate and advanced riders looking for improved windsurfing with sail performance.

Constant FH Curve Technology

The Constant FH Curve profile gives the mast a responsive top section with slightly stiffer mid characteristics. This creates a smooth and balanced sail shape that many modern windsurfing sails are designed around.

Advantages of the FH Curve include:

• Smooth sail rotation
• Stable draft position
• Excellent top-end control
• Better handling in strong wind
• Increased responsiveness during maneuvers

Reduced Diameter Mast Design

The RDM platform offers enhanced strength and comfort for demanding wind surfing conditions. The narrower diameter improves grip during waterstarts and transitions while also increasing resistance against impacts.

This design is especially appreciated by:

• Wave riders
• Freestyle sailors
• High-wind freeriders
• Advanced sport windsurf enthusiasts
