RRD DYNAMIC PRO CARBON MAST 85 Y31

The DYNAMIC PRO CARBON MAST 85 Y31 is engineered as a high end structure focused on maximum stiffness, precision, and long term durability for advanced hydrofoiling disciplines. At its core, an ACRYLIC FOAM CORE 200 kg/m³ is used to provide the ideal balance between lightweight construction and high compression resistance, ensuring structural stability under heavy loads while keeping overall weight controlled. The internal reinforcement is built with M40J carbon unidirectional fibers, optimized to deliver maximum longitudinal stiffness and direct energy transfer along the full length of the mast. The external structure features M40J biaxial carbon fibers, designed to enhance torsional and lateral rigidity, ensuring precise control, stability, and responsiveness even in demanding riding conditions. The outer surface is finished with a 3K carbon fiber layer and protected by a polished paint finish, delivering a smooth hydrodynamic surface, improved durability, and a premium aesthetic. All of this is integrated into a MONOCOQUE FULL M40J CARBON PLATE head connection, ensuring a perfectly rigid interface with the fuselage, eliminating play, and providing maximum structural continuity and direct power transfer.
