Highlights

What riders say

"Excellent for kiting or surfing and good for winging." - George Hradil

Wing / Surf / SUP / Kite / Wake

The new reflexed 1850R front wing gives you impressive control throughout the entire speed range, with extreme top-end speeds for such a large wing and an unbelievably low stall speed. Also a true crossover wing, the 1850R has more lift than the 1500R. In smaller to medium waves, prone foil surfers can perfect shorter radius surf-style turns with ease. Great for wing-foiling in all conditions and perfect for learning to foil, the 1850R is also still kite-able. Featuring our new, specialised reflexed-camber foil section design to give the wing pitch stability and prevent your board’s tendency to nose up strongly when you first get going. This eliminates the need for you to change your position to trim the board as you speed up, or as you drop-in on a wave. The 1850R has a relatively large surface area, which makes it highly controllable, with incredible roll and pitch stability. Usually, a large wing means more drag, hence less speed. But because it is positioned on the fuselage with a lower angle of attack, the 1850R feels smaller than it is in terms of speed range and responsiveness.

Performance crossover wing for heavier riders or lighter winds

In smaller to medium waves, prone foil surfers can perfect shorter radius surf-style turns with ease. Great for wing-foiling in all conditions and perfect for learning to foil, the 1850R is also still kite-able.

Reflexed technology for stability and speed

Our new, specialised reflexed-camber foil section design gives the wing pitch stability all on its own. It’s like we’ve built a mini-stabilizer into the trailing edge of the wing.

Self-trimming

The reflexed wing prevents your board’s tendency to nose up strongly when you first get going. Thus it eliminates the need for you to change your position to trim the board as you speed up, or as you drop-in on a wave.

Reflexed technology for stability and speed

Our new, specialised reflexed-camber foil section design gives the wing pitch stability all on its own. It’s like we’ve built a mini-stabilizer into the trailing edge of the wing which counters the downward pitching moment and gives you impressive control throughout the entire speed range, with extreme top-end speeds unheard of for a wing that size.

Self-trimming

Massive range, low stall-speed, incredible control

The Sonar reflexed wings have a relatively large surface area, which makes them highly controllable, with incredible roll and pitch stability. Usually, a large wing means more drag, hence less speed. But because you can position the reflexed wings on the fuselage with a lower angle of attack, they feel smaller than they are in terms of their speed range and responsiveness.
