Severne R4D – Foil Freemove
The R4D was born for your expression: freeride foiling, freestyle, carve moves on the foil and, if you want, pure “R4Dical”.
Designed with Balz “Radiculo” Müller , it is accessible for everyday sessions but ready for
Extreme aerial maneuvers. The new
Why choose it
- 4 battens (R 4 D) : perfect balance between maneuverability and stability on all sizes.
- Xtended Range : Maximum wind range with fewer sails in the bag.
- Among the lightest in its category : premium materials and strategic panel layout → less weight, more response, longer sessions.
-
Foil first , but with crossover on the fin for 360° fun.
“R4D is the smooth operator for your funboarding: flat lake in foil, lines in waves, radical jumps on foil or fin. Light, playful and easy to control sail: it gives you the confidence to push the limits in style.”
— Balz Müller
Technology & Construction
- Gradient Panel Technology : panels aligned to the loads and overlapping corners → less patch, less stretch, more stable and responsive sail.
- Reduced weight without sacrificing robustness: immediate response and neutral handling.
- High aspect profile for lift and early foil launch, especially in the medium/large sizes.
