K SDM-S SERIES: ADVANCED TECHNOLOGY, PERFORMANCE, AND CUSTOM FIT

Thanks to the latest updates in machinery, we’ve pushed the boundaries of mast construction with a new finish and the integration of cutting-edge technology. We’ve revised our sizes and models to boost carbon percentages, resulting in stronger, more durable masts that will elevate your ride. The K SDM-S series is designed specifically for fin sails, offering exceptional performance in traditional windsurfing. For foiling, we’ve also developed the F100 line, which is tailored to optimize sail foil performance.

Most masts on the market might appear similar, but that’s where the resemblance ends. They’re produced by different manufacturers using varying machinery, materials, climates, and technology, which means that even if the curve or IMCS numbers seem identical, the performance outcome once the mast is downhauled will be completely different.

Your mast is the backbone of your windsurfing rig—just like a tailor-made suit—it has to fit perfectly to perform at its best. A 9m slalom sail and a 5m slalom sail have vastly different performance characteristics and require masts with tailored curves and stiffness to ensure optimal performance in their respective conditions.

While most masts are labeled as constant curve, this term is a generalization that doesn’t explain the full picture. What matters are the curve percentage values of both the bottom and top sections, as well as the materials, shapes, and reflex—these are the true factors that define performance. These values can differ significantly between sail brands and are often kept secret.

The ultimate efficiency is achieved when you have an integrated rig, where every element—mast, sail, and fin—is optimized to work in perfect harmony.

We’re also proud to say that our factory is the only one producing its own carbon pre-preg. This gives us the huge advantage of using fresh, high-quality material in every production run—no storing, no freezing, and no compromise. Unlike other manufacturers who purchase pre-preg material from third parties and store it in and out of freezers, we ensure that every batch of material is freshly made for each production cycle, guaranteeing superior quality from start to finish.

THE NEW K’S GENERATION

SDM-S: STANDARD DIAMETER-SONIC

K SDM-S SERIES: THE SONIC EDGE FOR MAXIMUM CONTROL AND STABILITY

We’ve added the ‘S’ for Sonic to our SDM masts, introducing a new construction at the top of the mast that enhances reflex in the winglet area of the sail. This innovation significantly improves control and stability, giving you a sharper, more responsive ride on the water.

The K SDM-S masts are available in three carbon percentage gradients: K100, K93, and K77, each designed to offer different levels of performance and durability based on your needs. These masts are built to cover a range of conditions and sailing styles, ensuring you get maximum performance no matter your setup.

MAST 100% CARBON

K100 CARBON MAST: UNMATCHED PERFORMANCE AND CONTROL

The K100 Carbon Mast is built for those who demand the best performance from their gear. This mast delivers incredible pumping response, explosive acceleration, and a light feel that absorbs even the harshest conditions, ensuring optimal comfort and unshakable control. Featuring the ‘S’ for Sonic reflex, the K100 is equipped with an incremented layer of carbon at the tip, dramatically enhancing reflex in the top part of the sail.

The mast’s main structure consists of three layers of carbon for ultimate strength, while two unidirectional glass reinforcement sections are added to protect the mast from breakages, even under the harshest conditions. As the gusts hit, the K100 helps convert power into speed while keeping the sail light and responsive, maintaining full control throughout.

WHY THIS MAST: There’s absolutely no compromise in the K100 Carbon Mast’s performance. Designed for racing, it offers the best reflex and lightest weight, making it the perfect choice for those who want to dominate. While it offers outstanding performance, it requires extra care, as it’s built with minimal protection to allow the carbon to perform at its highest potential.

It offers the best compromise between performance and durability, making it ideal for riders who want top-tier results without the hefty price tag. Featuring the ‘S’ for Sonic reflex, an incremented layer of carbon at the tip boosts the reflex in the top part of the sail, enhancing responsiveness and control.

When compared to the K100, the performance difference is so minimal it can only be measured with a clock—you won’t feel a difference on the water. Built with the same high-performance construction, the K93 delivers outstanding performance that surpasses other masts in its class. With 3 carbon layers and 1 layer of glass, this mast is built to handle even the toughest conditions without compromising its performance.
