You will notice that the New EZ, GT, and RS models of Go Foil Front wings have what we call a "Step" on them.
These "Steps" are located out towards the wing tips. The steps help to stabilize the wings in respect to Wingtip Vortices issues that affect all airplanes and hydrofoils mostly at their wingtips.Wingtip Vortices are circular patterns that spin off of the tips of wings causing drag and instability.
The new Steps help to minimize the Wingtip Vorticesproblems that create drag and instability.
The Steps give the hydrofoil a more positive feeling through the water which leads to better pitch control. "Pitch control" means that you have better control with the up and down movement of the hydrofoil through the water. Better pitch control helps you to go faster with more confidence.
The steps create less drag by disrupting the Wing Vortices.
The angled Steps help with being able to initiate turns and redirect the hydrofoil. This means you can turn easier and sharper!
The Steps help to stop overfoiling. This is accomplished by disrupting air travel across the wing surface when you get close to the surface of the water. The step helps to keep the air from traveling straight across the wing surface by disrupting the easy flow of air across the wing by having an abrupt contour change. You will notice that you can get the wingtips out of the water on turns and reconnect with the water flow more easily than other wings. Twist in wing tips also can help with this problem but the "Steps" are like Twist or Winglets on steroids!
