Goya Extension Pro Carbon – RDM
Please call to order - 023 9258 2614
Graceful and rigid. Goya carbon extensions are lighter and stiffer to accept high loads especially on longer extension settings and large sails.
All Goya extensions use the super strong pin and collar system and come with a proven stainless steel power pulley and cleat. The RDM extension comes with a stepped hole layout to minimize weakening the shaft. These extensions offer the best weight to stiffness ratio, light and incredibly strong. Optimal block-to-block geometry and reduced friction are provided by aligning the pulleys of Goya sails to the pulleys of Goya extensions. All Goya extensions come as Universal Pin (Euro) models, designed to be compact and sleek.Duotone Power.XT 2.0 Alloy Windsurfing Extension

An inspiring (r)evolution – the POWER.XT 2.0 can do much more and do it better than the previous model. And as POWER.XT 2.0 SLS RDM 36 it is also the most lightweight ratchet extension of all time! Beyond the basic idea, the POWER.XT 2.0 has almost nothing in common with the previous model any more. From the extremely solid ratchet mechanism plus lever to the simplified release mechanism, the high-strength Lyros® Dyneema harness downhaul lines and the option to retrofit the damper function – everything has been radically upgraded. The latest version comes with a completely new adjustment ring, which offers a unique feature: based on the tried-and-tested SDM adjustment ring, the RDM version now for the first time ensures that the aluminum tube does not come into contact with the mast anymore, which avoids any contact corrosion. No other RDM extension can offer that! In order to guarantee the same durability despite the reduced diameter, a double-walled sandwich construction of 7075 aluminum outer tube and ovalized T8 inner tube is used (patent pending). For many years, the POWER.XT has been the benchmark when it comes to extensions with trimming tools. Those who use it will never want to do without it again. Thanks to the integrated lever, it overcomes even the strongest downhaul forces, enabling perfect re-trimming or fine-tuning even when on the water. Even children could handle the extreme luff tension of modern slalom sails, each profile can be adjusted to millimetre precision in a matter of seconds. The 15 cm long lever and the ratio of 1:60 enable trimming without any noticeable effort.
