RRD SWK Universal Full Carbon Masts (Wing/SUP/Surf/Kite Foiling)

A new unique and exclusive quality carbon mast, designed, built and finished as a diamond. Designed for hi performance wingfoiling, this mast is a huge improvement also for top level Surf / Sup and Kite use. Built with an exclusive hi density acrylic core to ensure lightweight and stiffness. The pre preg Carbon M40J TORAY® fibers used on this mast are only UD and Biaxial oriented (best layup mix for side and torsional stiffness), with a finishing layer of 3K carbon for best smooth surface.

With a Tensile modulus (stiffness) of 54,7 Msi (million pounds on square inches) and a Tensile strength (axial stress amount before breaking) of 640 Ksi ( kilo-pound per square inches) the TORAY® M40J carbon is the best PAN BASE carbon fiber available in STD weights for premium sport goods applications.

Please realise that the MJ line of Carbon fibers from Toray® are the most expensive carbon fibers in their range and very limited in terms of availability with the longest lead-time from order. Please do not only consider a Carbon mast for its lighter weight compared to an Aluminum mast. Using a lower modulus carbon fibers it is possible to make a lighter mast, but it will most likely have poor torsional and side stiffness. Often a light weight mast is synonymous of poor stiffness and durability. Always choose quality when hydrofoiling, and quality #1 on a hydrofoil mast is: STIFFNESS.
