SDM & RDM Carbon Fiber Windsurf Masts

Note: IMCS value refers to the IMCS Mast Windsurf standard, which measures mast stiffness. A higher IMCS number means a stiffer mast. Always match your mast to your sail's recommended IMCS range for best performance.

Lightweight Construction

Our carbon fiber windsurf mast is significantly lighter than fiberglass alternatives. This reduces swing weight, making your rig easier to handle and faster to react.

Consistent Flex Curve

Each carbon fiber windsurfing mast is cured under controlled temperature and pressure, ensuring a smooth, predictable bend curve. This helps your sail set correctly and perform as designed.

Two Diameter Options

SDM Mast: Larger diameter for maximum stiffness and stability. Ideal for larger sails and race conditions.

RDM Mast: Smaller diameter for lighter weight and better shock absorption. Preferred for wave and freestyle sailing.

High Fatigue Resistance

Carbon fiber does not fatigue like metal. Runfeng CRFP's windsurf mast will maintain its flex properties after thousands of hours on the water.

UV and Saltwater Resistant

The outer surface is protected against UV degradation and saltwater corrosion, extending the life of your mast in harsh marine environments.

Wave Sailing: The 460 RDM mast and 430 RDM mast are ideal for wave riders who need quick response and impact resistance.

Freestyle: RDM masts offer the flex and durability needed for technical tricks.

Freeride: The windsurf mast 400 SDM is a great choice for recreational riders who want a balance of performance and comfort.

Race and Slalom: The SDM RDM mast in 490 cm and above delivers the stiffness and stability required for high-speed racing.

Formula and Longboard: Longer SDM masts provide the power and control needed for large sails.

No matter your discipline, there is a carbon fiber windsurf mast in our range that fits your board, your sail, and your style.

Tip Section

The top of the mast is tapered and reinforced to reduce weight while maintaining strength. This improves the sail's top-end twist and overall performance.

Surface Finish

The mast surface is smooth and coated for UV protection. It is available in matte or gloss finish depending on your preference.

Ferrule Joint

For two-piece masts, the ferrule joint is precision-machined to ensure a tight, wobble-free connection. This is critical for maintaining the mast's designed flex curve.

Our masts are tested to meet international standards for strength, stiffness, and durability. Each production batch undergoes:

FAQ

 

Q1: What is the difference between SDM and RDM?

A: SDM mast stands for Standard Diameter Mast. It is thicker and stiffer, best for larger sails and racing. RDM mast stands for Reduced Diameter Mast. It is thinner, lighter, and more flexible, best for wave and freestyle sailing.

 

Q2: What does IMCS mean?

A: IMCS mast windsurf is a standard for measuring mast stiffness. A higher IMCS value means a stiffer mast. Always check your sail's recommended IMCS range before buying.

 

Q3: Which mast should I choose for wave sailing?

A: For wave sailing, we recommend the RDM 460 mast or RDM 430 mast. These offer the lightweight feel and shock absorption you need in waves.

 

Q4: Can I use an SDM mast with an RDM sail?

A: No. SDM and RDM masts have different diameters. Your sail's luff tube and extension are designed for one type only. Mixing them will not work properly.

 

Q5: Do you offer a 400 SDM mast?

A: Yes. The SDM 400 windsurf mast is available in our freeride range. It is a good choice for smaller sails and lighter riders.

 

Q6: How do I know if my mast is still good?

A: Check for cracks, soft spots, or visible damage. If the mast feels different from when it was new, or if it has taken a hard impact, it may need to be replaced. Carbon fiber masts can develop internal damage that is not always visible.

 

Q7: Can you produce custom IMCS values?

A: Yes. We can adjust the fibre orientation and curing process to achieve the specific IMCS windsurf mast for OEM customers.
