North Sonar SF830 We’ve engineered our Surf Front Wing Series for super low stall speeds, effortless pumping, and surf-style carving. These wings deliver industry-leading roll control, stability, and agility, prioritising powerful rail-to-rail carves and tight banking turns. With a forgiving recovery, they accelerate quickly back up to speed in one or two pumps and transfer energy from even the smallest waves. Perfect for assisted foiling, parawing, prone, wake-thieving and wing surfing, the Surf Series generate maximum lift in the lower speed range, for smooth, sustained glide. Available in six sizes from SF530-SF1230. Pair with the Surf /5 Series Stabilizers, also designed to operate at slower speeds.
