Windsurf mast Loftsails Vision IV C75 RDM

Versatile high-carbon RDM mast Loftsails Vision IV C75 RDM is designed for windsurfers who want a noticeable improvement in sail response without moving to a full-carbon competition mast. Its 75% carbon content provides quick recovery after flexing and helps reduce rig weight while maintaining the durability required for frequent sailing. The mast is suitable for recreational freeride, competitive sessions with other riders and regular wave sailing. It offers a practical balance of response, durability and price for intermediate and advanced windsurfers. T700 and T800 carbon fibres The mast is made using a combination of T700 and T800 carbon fibres. This material blend provides the required balance of elasticity, low weight and resistance to the loads generated during sailing. The high carbon content improves mast reflex, allowing the sail to recover its intended profile more quickly after a gust, landing or impact with chop. This results in a more direct rig response, stable power delivery and easier acceleration. Durable pre-preg construction Loftsails Vision IV C75 RDM is manufactured using pre-preg materials. The fibres are pre-impregnated with a controlled amount of resin, which produces a consistent laminate and reduces variation between individual masts. The construction is designed to withstand the demands of wave sailing and intensive use. It also provides suitable resistance to localised loads and friction generated by the sail during operation. Constant Curve bend profile The mast features a Constant Curve bend, with 64% base flex and 76% top flex. This bend profile is matched to Loftsails sails and allows the sail to maintain its intended draft depth and leech behaviour. A correctly matched mast also helps provide the full tuning range of the sail. The profile remains stable, while the upper section can respond effectively to changes in wind strength. Controlled mast specifications Precise manufacturing methods reduce differences in bend characteristics between individual masts. Every mast is checked and controlled to ensure that it meets the intended flex and stiffness specifications. This is particularly important in performance sails, where even small variations in mast behaviour may affect draft position, stability and usable wind range. RDM diameter The reduced diameter makes the mast easier to grip during manoeuvres and waterstarts. The RDM construction also offers a favourable wall thickness-to-diameter ratio, improving resistance to localised impacts. An RDM mast provides a slightly softer and more controlled rig feel than a comparable SDM model. This is particularly useful in wave sailing, choppy water and variable wind. Who is it for? Loftsails Vision IV C75 RDM is designed for intermediate and advanced windsurfers sailing freeride, bump & jump and wave. It is a suitable choice for riders who want faster reflex and lower rig weight than a C50 mast, while retaining more durability and a lower price than a C100 model. Before purchasing, check the mast length, diameter, IMCS stiffness and bend curve recommended by the sail manufacturer.
