Windsurf mast Loftsails Team Edition IV C100 SDM

High-performance SDM windsurfing mast Loftsails Team Edition IV C100 SDM is the most advanced SDM mast in the brand’s range. It is designed for sails where fast response, profile stability and efficient recovery after each gust are essential. The standard SDM diameter provides high structural stiffness and reliable support for the sail profile. It is particularly well suited to slalom, race and freerace rigs, where precise mast behaviour translates into better acceleration, control and stability at speed. T700 and T800 carbon construction The mast is made from a combination of T700 and T800 carbon fibres. Using both types of carbon helps achieve low weight, high responsiveness and suitable resistance to the loads generated during sailing. The mast is manufactured using pre-preg material, meaning that the fibres are pre-impregnated with a precisely controlled amount of resin. Compared with traditional wet layup methods, this process creates a more consistent laminate and reduces excess resin, which would otherwise add unnecessary weight. Autoclave-cured construction The mast is cured in an autoclave under controlled pressure and high temperature. This process improves the bonding between the carbon layers, increases tensile strength and helps maintain consistent bend characteristics. As a result, the mast responds quickly to changing loads, allowing the sail to work more efficiently in gusts, during pumping and while accelerating. This is especially important in sails whose profile depends on accurately controlled mast tension. Constant Curve bend Loftsails Team Edition IV C100 SDM features a Constant Curve bend profile. The base flex is rated at 64%, while the top flex is 76%, matching the bend characteristics used in Loftsails sails. The correct bend curve helps maintain the intended draft depth, leech release and tuning range. Every mast is checked and controlled to minimise differences between individual units and sizes. Low weight and fast reflex The 460 cm version weighs approximately 1.95 kg. Its low weight reduces rig inertia, making the sail easier to handle during manoeuvres, waterstarts and dynamic sailing. The high carbon content also improves reflex, meaning the mast returns to its original shape quickly after bending. This allows the sail to recover its stable profile faster, helping maintain drive and control in variable wind. Who is it for? Loftsails Team Edition IV C100 SDM is designed for advanced windsurfers, racers and riders using performance-oriented Loftsails sails. It is a suitable choice when precise sail response, low rig weight and the intended sail design characteristics are the priority. Before purchasing, check the recommended mast length, diameter and bend curve specified for your sail.
