More info

The foils insensitivity to angle of attack change forgiveness means you don’t have to be an expert or have perfect pumping technique. A refined balance of roll stability and manoeuvrability gives you confidence during pumping and take-offs, and the ability to initiate powerful rail-to-rail carves. Push it harder, lip stall and lay down banking turns, knowing tip ventilation is a thing of the past. Reduced distance between the mast and front wing makes for faster, tighter pivoting turns. We’ve kept the span similar between the three sizes, providing the same ride feel across the entire size range. The SF promises that 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 Sonar SF Series. At one, with it all.

Technology:

  • Progress faster
    The SF-Wings are easy to pump but still manageable to roll from rail to rail. The area-distribution across the span is tuned to the rolling ability of the wing - less area in the tips helps the foil to roll with lower force from side to side.
  • Effortless pumping
    The foil is super forgiving on angle of attack change - when you're about to stall, give it one pump, then you're back in the game.
  • Match with S215 Stabilizer
    Because the SF front wings operate at such low speed without stalling, you need a stabilizer that does the same. With smaller front wings, you want to upgrade to a smaller stab, but it's important to match the stall speed. The S215 was created with lower stall speed to complement that of the SF front wings. Advanced riders who are seeking a looser feel may choose to remove the wingtips, using the dashed quideline graphic, to create a completely flat stabilizer with a 205cm2 area.
  • Composed glide
    The SF can be compared to our highly efficient HA Front Wings - only with a much lower speed range. Our Sonar HA Series has a phenomenal glide at medium to high speed - we've engineered the same glide into the lower-speed SF-Front Wings. Their aspect ratio ranges
    from 71 (SF1230) to 8.8 (SF930). This can be considered medium-high, however because of the evolved foil section, the stall speed is remarkably low. They can deliver that frictionless sensation of glide at a much lower speed.
  • Responsive turning
    We've moved the wing back on the fuselage for a better turning response, so you may need to move the mast further forward in the mast track compared to other North wings. Mounting the front wing closer to the mast reduces your yaw stability, so you can initiate turns
    more easily.
