Windsurf Masts

Types of Windsurf Masts

SDM (Standard Diameter Mast)

Standard diameter masts are the most common type used by windsurfers. They have a uniform diameter throughout their length and offer a good balance between performance, durability and price. These masts are suitable for a wide range of sailing conditions. If you are in doubt as to whether you should have an SDM mast, this rule of thumb can be helpful: If your sail is over 6.5m2, an SDM is usually a super good choice. However, remember that this is just a rule of thumb and personal experiences and preferences can mean something completely different.

RDM (Reduced Diameter Mast)

Reduced diameter masts have a thinner diameter than standard diameter masts. They are designed to be lighter and more flexible, providing better maneuverability and improved performance. These masts are commonly used on sails under 6.5m2, but again this is also just a rule of thumb that you can go by if you are in doubt or new to the sport.

Remember, regardless of whether you choose an SDM or RDM mast, the mast extension must of course fit the chosen mast type. Check out our range of mast extensions by clicking here.

Construction of windsurf masts

Windsurfmaster is primarily made of two types of materials: fiberglass and carbon. Each material has its specific properties and offers different performance levels and price ranges.

Fiberglass mast Fiberglass mast provides a good balance between durability, flexibility and cost. Fiberglass masts are often used by intermediate windsurfers who want better responsiveness and performance without being expensive. Carbon mast

Carbonmasts is the best choice for windsurfers who want the highest level of performance, as this type of mast is extremely light, responsive and extremely stiff. The Carbonmast provides excellent power transfer and is preferred by competitive windsurfers who demand the best possible performing equipment.

You will also find a long line of masts that are mixed masts. This means that a mast can, for example, be constructed of 50% glass fiber and 50% carbon fiber. This means that you can certainly find a mast that suits both your windsurfing level and budget.

Mast specifications

In order to make an informed decision when looking for a windsurfing mast, it is important to understand the different specifications associated with the masts. Length The length of the mast is measured in centimeters and has a direct influence on the performance of the sail. Longer masts generally provide more stability and power, while shorter masts improve maneuverability and control. Choosing the correct mast length depends on your sail size and personal preferences.

Flexibility
The flexibility of the mast determines the way the sail reacts to the wind pressure. Stiffer masts provide more direct power and responsiveness, while softer masts provide increased twist and depowering possibilities. It is crucial to find the right balance between flexibility and performance in order to achieve optimal performance in different conditions.

Bend Curve
The bending curve, also called bend curve, refers to the shape of the mast when it is loaded. Different bending curves suit different sails and sailing styles. Some masts have a constant curve, while others have a more progressive or even a hard top bend. By experimenting with different bending curves, you can fine-tune your setup to suit your preferences.

IMCS (Indexed Mast Concept System)
The Indexed Mast Concept System is a classification system that provides a standardized measurement of mast stiffness. The IMCS numbers are associated with specific mast bends, so you can compare and select masts with similar characteristics across different brands. A lower IMCS number indicates a stiffer mast, while a higher number means a softer mast.
