The Duotone Platinum Series SLS 100% carbon windsurfing mast is the lightest RDM mast in its class, available in RDM and SDM versions to suit freeride, wave and race sails.
The Duotone PLATINUM SLS series was developed for World Cup pros and anyone else who expects the very best, and has been continuously fine-tuned ever since. The highly customised, extremely dynamic PLATINUM RDM, which is produced to AERO 1.0 design specifications, has over 30% less weight but has lost nothing in terms of durability compared to previous models. Even under the harshest conditions, wave world champion Victor Fernandez uses only these masts.
All SDM variants, particularly the higher-length models, are designed for competitive races and are also protected against scratches by the abrasion-resistant POLY.SHIELD surface. Both RDMs and SDMs are manufactured using AEROSPACE PREPREG TECHNOLOGY – the most precise and high-quality process known. For this reason, Duotone are the first manufacturer to offer an unconditional two-year warranty* for 100% carbon masts (*when registered online within 30 days – see Warranty below).
