Aluminium MDM Extension – Power and control made simple

The North Sails Aluminium MDM extension is built to save rigging time and maximize on-water performance. A lighter alternative to the carbon version, it keeps all the top-tier features needed for intense slalom or freerace sessions.

Effortless downhaul, high efficiency

Equipped with 4 oversized, corrosion-resistant plastic pulleys aligned perfectly with your sail, and a low-stretch Dyneema rope, this extension delivers an 8-to-1 mechanical advantage for fast and precise tensioning.

Quick adjustment and secure locking

The Pop & Slide ring makes adjusting length intuitive and quick. A discreet U-Pin button with manual locking adds safety and reliability during long-distance sailing or open ocean runs.

Built to last

All components are crafted for longevity: high-grade plastics, stainless steel parts, and a mushroom-style sand stopper keep the system clean and reliable over time.
