Description
Playful on the wave, efficient when pumping
The Whizz SLS front wing has a medium aspect ratio of 8.5 that balances pumping and manoeuvrability. Its straight, unswept outline maximises the lift-to-drag ratio, and the progressive dihedral makes it especially playful and responsive. Its profile, similar to that of the Glide 2145, delays stall so you can exit the wave at low speed and keep pumping. Sold on its own, without stabiliser.

Light and strong, with a great balance between weight, stiffness and strength.
06 Innovative dihedral
For smooth rail-to-rail turns.
07 Pumping profile
Profile and camber optimised for pumping, with a very low stall speed.
08 No sweep
Straight design for maximum pumping efficiency.

Official Duotone data. Stabiliser not included. The 700 size is in store but Duotone hasn't published its data yet: ask us. Screws: 3x M8x30, 15 Nm torque. Duotone recommends the 66 cm fuselage, positioned slightly further forward in the tracks than with the Carve or Glide. Check the selector for the sizes available in store.
“The Whizz is the most manoeuvrable foil I've tried with good glide. It's easy to pump back out to the next wave and it's great in tight turns and quick rail changes. The 850 is my surf foil and one of my favourites for winging in small waves.”
Technology and construction
- S stabiliser: low sweep and slight dihedral for a fun, loose feel; a different profile from the P and C that improves the pumping of the whole setup.
- Thickness and camber per size: each size has its own thickness and camber for a wide speed range and powerful lift at low speed.
- Anti-stall profile: similar to that of the Glide 2145, it delays stall.

Frequently asked questions
Does it include a stabiliser?+
No. Duotone recommends the S stabiliser in the size shown in the table for each size.
Which size should I choose?+
The small ones (700-850) for advanced surfers and wing or kite in waves; the large ones (1200-1450) for learning prone or wake, heavier riders or SUP foil in weak waves.
Which fuselage should I use?+
Duotone recommends the 66 cm one; the 60 cm makes it more playful and the 74 cm more controllable.
