Product Benefits
Ideal for recreational use
The Essentials SDM V2 line is designed as a practical solution for beginners and recreational windsurfers. It offers good ease of use and essential construction, focused on daily functionality without unnecessary complications.
Easier downhaul
The base integrates 3 larger diameter pulleys, designed to make downhauling smoother and less strenuous. This helps simplify sail rigging and improves tension management, especially for those seeking an intuitive system.
Lightweight and practical
The aluminum construction helps keep the weight down and makes the extension easy to handle. This is a useful feature for those who prioritize simplicity, comfort of use, and practicality when assembling equipment.
Quick line release
The positioning of the line locking system allows the downhaul to be released with a quick motion. This makes it more practical to use during rigging and de-rigging operations.
Not intended as a race extension
Due to its construction and rigidity, this extension is more suitable for freeride and recreational use. The basic structure and tube are not designed as a specific solution for high-tension race sails.
