In short, yes—wing foiling is easier to learn than windsurfing.
Windsurfing gets you on the board quickly, but mastering the technique to gain speed can take months and is physically very demanding. Wing foiling has a quicker learning curve; by the second lesson, you’ll be winging on a larger board without the foil, and within 10 to 15 hours, you’ll likely be up on the foil and picking up speed. It’s also much less physical, with lighter and easier-to-handle equipment.
