Windsurf mast Loftsails Team Edition IV C100 RDM

Loftsails’ highest-specification RDM mast Loftsails Team Edition IV C100 RDM is the top RDM model in the brand’s mast range. It is designed for riders who expect low weight, fast response and consistent bend characteristics. The reduced RDM diameter improves grip, makes the rig easier to control and increases resistance to localised impact. At the same time, the 100% carbon construction delivers the fast reflex required by high-performance sails. T700 and T800 carbon fibres The mast is made from a combination of T700 and T800 carbon fibres. These materials are selected to provide a balanced mix of low weight, responsiveness and durability. T800 fibres contribute to stiffness and fast recovery, while T700 fibres help improve resistance to regular sailing loads and impact. This combination maintains performance without excessively compromising durability. Pre-preg and autoclave-cured construction The mast is produced using pre-preg technology. The fibres are pre-impregnated with a controlled amount of resin, creating an even and lightweight laminate without unnecessary excess material. The mast is then cured in an autoclave. High temperature and pressure consolidate the carbon layers, improving tensile strength and resistance to friction and repeated flexing. Constant Curve and consistent sail behaviour The Constant Curve bend profile is matched to the characteristics used in Loftsails sails. Base flex is rated at 64%, while top flex is 76%, helping the mast support the intended sail profile and leech release. Every mast is checked and controlled for bend consistency. This reduces differences between individual units, which is particularly important in high-performance sails that require an accurate mast match. Fast reflex in variable wind The high carbon content allows the mast to recover quickly after bending. The sail responds efficiently to gusts, maintains drive and stabilises its profile faster after sudden changes in load. This is useful during pumping, acceleration, sailing through chop and handling variable wind. The rig responds with less delay, making it easier to maintain speed and control. RDM diameter The RDM construction is narrower than a standard SDM mast. It is easier to hold during manoeuvres and waterstarts, while the thicker wall-to-diameter ratio improves resistance to localised impact. An RDM mast can also provide a slightly softer and more controlled rig feel. Final compatibility still depends on the sail manufacturer’s recommendations, so the required length, diameter and IMCS rating should always be checked before purchase. Who is it for? Loftsails Team Edition IV C100 RDM is designed for advanced windsurfers and riders using high-performance sails that require a Constant Curve mast. It is a strong choice where low weight, fast reflex, controlled sail response and accurate mast-to-sail compatibility are the priorities.
