SX4 Alu


170 USD230 USD

The SX4 is our entry-level boom. If you are starting out your windsurf journey, this is the boom for you. It features a super stable quick lock front which works on both SDM and RDM masts. A thin grip so even riders with smaller hands can get a sturdy grip. As on our other booms the SX4 has the double pin lock system which gives a very stiff connection between the boom body and tail end, even when maximally extended. The generous tail extension will cover most of sail sizes you need to get going.

The SX4 series is all about getting out on the water and enjoying.

The outline and width of the tail are crucial for the rig to deliver the right balance between power and control. The outline on the 140 and 160 booms are designed specifically bump n’jump sailing where you want to be closer to the rig for control. The 180 booms has a wider outline to get momentum on the rig to go really fast. A wider tail generates more power and a more narrow tail piece more control. This position varies with the wind strength and windsurfing discipline, therefor each boom size have been developed individually.
