Presenting the Duotone Whizz SLS foil, the latest addition in Duotone foil collection, tailored for avid wing, prone and wake foilers. This new foil complements the Carve 2.0 and Glide series, engineered to yield a wing that effortlessly pumps through waves, facilitating seamless wave connections, and delivering outstanding agility for executing sharp turns on the surf.

The Whizz SLS has a mid-aspect ratio of 8.5, striking a balance between efficient pumping and maneuverability. Its straight outline maximizes lift-to-drag ratio for better pumping. The wing’s unique appearance, especially from the front, features a progressive dihedral shape that enhances its playful and responsive feel.

The range comes in sizes 850, 1000, 1200, and 1450. The smaller ones suit experienced surf foilers desiring enhanced wave manoeuvrability but also ideal for wing and kite foiling. The larger sizes cater to heavier riders seeking an easier learning platform or to progress in wing foiling. Additionally, they’re great for SUP foiling in slow, weaker swells, and provide a playful option for dockstart wings for intermediate to advanced riders.

For best results, pair the Whizz front wing with a 66cm fuselage, positioned slightly forward in your tracks compared to our Carve or Glide wings. For a playful feel, try a shorter 60cm fuselage, or for more stability, go for the longer 74cm option.
