We’ve engineered our Sonar Surf Series for super low stall speeds, effortless pumping and surf-style carving. Ideal for riders wanting more from the surf and downwind swells (with or without a wing). The foils insensitive to angle of attack change means you don’t have to be an expert or have perfect pumping technique.
The SF promises a frictionless sensation of glide at slower speeds. Responsive and agile. With intuitive recovery. Wakesurfing ten waves back, prone surfing, wing-surfing, pumping or mastering the downwind.
The SF Series. At one with it all.
