Sail North 2025 Rad

The Severne Rad 2025 windsurf sail is an ultra-light, high-performance, camless crossover sail designed for maximum control and dynamics in all conditions.

R4D has been designed for YOUR style ride. You can use it for freeride foiling, treat it as a freestyle sail, carve it on the foil and go as R4Dically as you dare.

Developed in collaboration with Balz “Radiculo” Müller, this sail adapts to the ambitions of every rider. Balz performs his signature aerial tricks on it, while the R4D remains accessible for everyday sessions, pushing traditional boundaries. The new FoilWave dimension opens up unexplored territory – you can draw lines on the waves regardless of the conditions.

Four battens – that’s what the “4” in R4D means. This setup provides the perfect balance between agility and stability across the entire size range. Smaller sizes facilitate quick turns, medium sizes offer versatile performance, and larger sizes provide freeride power without unnecessary weight.

A solid yet ultralight construction makes the R4D one of the lightest sails in its class. High-quality materials and strategic panel layout eliminate unnecessary weight without sacrificing durability. Less weight means better response and longer sessions.

Rediscover the true feeling of freedom that started it all. The versatility of the R4D, supported by the Xtended Range, eliminates unnecessary complications – maximum range, minimum gear. Break the barriers – R4Dical freedom awaits!.
