Perfectly matched to our Racing Series, the KONCEPT and the KA.RACE, these masts are all about allowing you to reach your personal goals, be it a PB on your GPS or winning at the PWA Slalom, no matter if you prefer to sail with RDM (in the smaller sizes sails) or SDM (in all sizes).

Utilising the same bend curves as our SDM masts, the RDM 100% masts can be used across the complete KA Sail Range. Highly recommended for wave sailors who want the absolute best in radical conditions, they are also perfect for speed sailing on the smaller KONCEPTS with RDM cams fitted.

As part of our intense Ka.RT (Ka Rig Technology) program, we have developed a unique lay-up for all of our masts. This enables us to optimise weight without sacrificing the durability, resulting in a super responsive rig that flexes consistently and reacts instantly. The mast bend curves are matched perfectly to our luff curves, ensuring the sails behave exactly as the designers intended them to, and also twist and draft placement have been optimised.
