The New Step Series
The new EZ, GT, and RS models of Go Foil front foils have what we call “Steps” on them.
These “Steps” are located out towards the tips. The steps help to stabilize the wings in respect to Wingtip Vortices issues that affect all airplanes and hydrofoils at their wingtips. Wingtip Vortices are circular patterns that spin off the tips of wings causing 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. They 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 over-foiling. This is accomplished by disrupting air travel across the wing surface when you get close to the surface of the water. Think of Wingtip Vortices problems like this: Air is getting sucked down from the surface of the water in the form of a mini tornado. The steps help to keep that air from traveling straight across the whole wing surface by disrupting the easy flow of air across the wing with the abrupt contour change of a Step.
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!
Front wings are CNC shaped PVC cores with outer skins of 100% carbon with integrated cone construction connected to both top and bottom surfaces.
We use an excess amount of fiber on our wings @ 1000gm2 surface fiber loading.
All wing tips are solid carbon for maximum durability!
