Windsurf masts

Surf masts

Surf masts are an important part of your windsurf equipment. The right or wrong choice of a surf mast can make a big difference in the performance of your windsurf sail. As Telstar Surf, we recommend that you purchase the right windsurf mast for each sail. You can find which mast you need at the bottom of your sail or in our specification table on the website. Sometimes cheaper masts are interesting, but keep in mind that these masts deliver slightly less performance than the more expensive masts.

Disciplines and surf masts

Windsurfing has many disciplines, making choosing a mast even harder. To get more clarification about this, we will explain for each sail which mast is the best option.

Freeride: Freeride windsurfing is a playful way of windsurfing. Freeriding is not an extreme form of windsurfing and therefore does not require a super strong mast. Some freeride sails require an SDM mast and others RDM. For clarification, we have set per mast of 2019+ in the specification table which mast is required for the specific sail.

Freerace: Freerace is a combination of freeride and slalom windsurfing. Freeracing is for the windsurfer who wants to hit the water in a fun way. Because you want to make a lot of speed while racing, a large sail is needed. 7.2 and 7.7 m2 are the most commonly used sizes and require an SDM mast. The SDM mast is thicker at the bottom and narrower at the top, so that it flexes flexibly with the sail when there is a lot of wind. For clarity, it is indicated for each sail of 2019 and older in the specification table whether an SDM or RDM mast should be used.

Slalom: Slalom is an aggressive way of windsurfing. Neck to neck racing in combination with high speeds are no weird things in the slalom world. Because sailing has to be hard, big sails are very useful. These windsurf sails are best to use with SDM masts because the SDM masts bend easily in strong winds, which means that maximum speeds can be achieved. To create clarity, it is indicated for each sail of 2019 and older in the specification table whether an SDM or RDM mast will apply to the specific sail.

Wave: Wave surfing is done on the waves, as the name suggests. Because waves break at a certain point, you may end up with your set below. A mast is very vulnerable at such a moment and can therefore break quickly. RDM masts are therefore suitable for wave windsurfing. The RDM masts have a thicker inner wall, making them less likely to break compared to the SDM masts.

Freestyle: Freestyle windsurfing is a fun way of windsurfing if you like to make tricks. Because a lot of hard blows are made on the water, the chance that your mast will first touch the water is high. A hard blow can damage or even break a mast. That is why the RDM mast is a perfect mast for freestyle windsurfing. RDM masts have a thicker wall that provides strength, this is likely to reduce the chance that your mast will be damaged or broken compared to the use of an SDM mast.

Mast specifications

Masts come in all shapes and sizes, we just talked about SDM and RDM, but there are more things to look for when purchasing a mast. We will tell you a little more about this.

Carbon percentage

 Each mast has a carbon percentage. This means what percentage of carbon is in the mast. The higher the percentages, the more carbon is in the mast. Masts with a lot of carbon in them, think of 75+ percent carbon, are often used for slalom and racing. This is because the masts are easy to control, they create a lot of speed and are easy to get into planing. The carbon masts are also a bit lighter, which makes them feel more dynamic which can help a lot with handling the sail. Freeride, wave and freestyle windsurfers can also opt for a mast with a lot of carbon in it, but the chance of a broken mast is considerably higher. Because carbon is very strong over its entire length, but weak at one point, it can happen that a crack will appear after making a smack on the water.


There are different types of curve towers, namely: Hard top, flex top and constant curve. Because each mast has its own construction method, we do not recommend using a different brand of mast on a specific brand sail because this is won’t feel as comfortable as if you would use the same brand for sail and mast.
