Windsurf mast Loftsails Vision IV C75 SDM with mastbag

SDM mast for freeride and performance sailing Loftsails Vision IV C75 SDM combines the fast response of high-carbon masts with the durability required for regular use. It is designed for recreational freeriders, more performance-oriented windsurfers, and riders using sails equipped with cambers. The 75% carbon content helps reduce rig weight and provides faster reflex than C50 masts. At the same time, the construction remains more durable and more affordable than high-performance 100% carbon models. T700 and T800 carbon fibre construction The mast is made from a combination of T700 and T800 carbon fibres. These materials provide high elasticity, efficient recovery after bending, and resistance to the loads generated during acceleration and sailing in stronger wind. Fast reflex helps the sail stabilize its profile after gusts and changes in load. The rig responds more efficiently, allowing the rider to maintain drive, speed, and control more easily in choppy conditions. Durable pre-preg laminate Loftsails uses pre-preg technology, where the fibres are pre-impregnated with a precisely controlled amount of resin. This creates a consistent laminate while reducing excess material that would otherwise increase weight. The construction is designed to handle the loads generated by camber-equipped sails. The mast surface and laminate provide suitable resistance to friction caused by camber rotation and regular sail movement. Standard SDM diameter The SDM diameter provides high structural stiffness and stable support for the profiles of larger sails. It is particularly well suited to freerace, raceboard, and other performance-oriented sail setups where maintaining a deep and stable draft is important. The standard diameter also supports smooth operation of compatible cambers, helping maintain predictable profile rotation during transitions and sail stability at higher speeds. Constant Curve bend profile Loftsails Vision IV C75 SDM features a Constant Curve bend characteristic. The base bend value is 64%, while the top is 76%, matching the curve used in compatible Loftsails sails. The matched bend profile helps the sail achieve the intended draft depth and correct leech opening. It also supports a broad tuning range through downhaul and outhaul adjustment. Consistent production quality Loftsails uses precise manufacturing methods to reduce variation between individual masts. Each mast is checked for parameters that influence its performance. Consistent characteristics are important not only for racers. They also make it easier for recreational riders to tune the sail according to the manufacturer's recommendations and use its full wind range. Good balance between performance and durability Vision IV C75 SDM is lighter and more responsive than basic masts with lower carbon content. At the same time, it is not as delicate or expensive as top-level C100 models. It is a practical choice for riders looking for a more performance-oriented rig response while still needing a mast suitable for regular sessions, training, and frequent transport. Mast bag included The mast is supplied with a protective bag for easier storage and transport between spots or during trips. Who is it for? Loftsails Vision IV C75 SDM is designed for intermediate and advanced windsurfers riding freeride, freerace, or using larger camber-equipped sails. It is a suitable choice for riders who value a stable sail profile, fast response, and good structural durability. Before purchasing, check the recommended mast length, diameter, IMCS stiffness, and bend curve specified for the sail.
