Foil Freemove: the 4-batten no-cam sail for foil, freestyle and wave, developed with Balz Muller.
The R4D is a 4-batten sail specifically designed for foil, developed in collaboration with pro rider Balz "Radiculo" Muller. It balances maneuverability and stability across the entire size range, making it probably the lightest all-round no-cam sail in its category. The design caters to different ambitions, from aerial acrobatics to everyday sessions, while also introducing a "FoilWave" dimension for surfing in varying conditions.

Frequently asked questions
What is the difference between the "Pro" sails and the standard versions?
The Pro versions use 100% welded CarbonFusion construction (no stitching), making them lighter, more responsive and with a wider wind range than the standard X-Ply versions, at a higher price.
What mast should I use?
Each sail is designed for a precise flex curve (measured by Severne at 7+ points instead of the industry standard 3 points): use the RDM or SDM mast recommended in the technical sheet for the chosen model and size to achieve the correct profile.
How do I choose the right size (m²)?
The size should be chosen based on your weight, level and expected wind conditions: smaller sizes for strong winds or light riders, larger sizes for light winds or for those seeking more power. Each model covers an extended wind range thanks to Xtended Range/XR technologies.
What is included with the sail purchase?
The sail comes ready to be rigged on the recommended mast and boom (sold separately unless otherwise stated); it does not include a mast, boom or extension unless specified in the technical sheet.
