A web of fibreglass filament that diffuses sail loads across seams and throughout the body of the sail.
Traditional sail-making utilises small corner patches that diffuse the load approx 30cm, often ending before or even at a seam creating a weak spot that is susceptible to damage. By using stronger, lighter fibres these radials measurably reduce weight and increase strength. For improved manoeuvrability, swing weight is also reduced as the clew patch weight has been replaced with lightweight vectors that extend the full width of the foil.
Radiates load from the clew through the sail body bridging vital seams.
Massively increases perimeter strength.
