North Sails RDM extensions ensure that you spend less time rigging and maximize your time out on the water. The Carbon is our lightest RDM extension, offering a more compact and stiff material for optimum rigging and performance. All North Sails extensions are ... packed with innovative features. The loop-loop-go system makes rigging simple and seamless, even on the downhaul. The low stretch Dyneema rope greatly reduces friction, and downhaul can be applied with just your hands on most Wave and X-Over sails. The extension ring has a simple to use Pop & Slide system, so setting the right length becomes intuitive. The U-Pin button sits discreetly on the extension tube and has a manual locking function for safety and peace of mind, whether you’re in the waves or during long slalom reaches. High-grade plastic and stainless steel components ensure the extension will be in your quiver for many years to come.

"Keeping it simple, light and bomb-proof was the goal. Having a perfectly aligned loop-loop system with low friction materials and the Dyneema rope allows you to apply downhaul with ease."
