Foil

Wingfoil, SUP Foil, Surf Foil, Hydrofoil

A hydrofoil is a wing construction that is mounted under a board. The sword-like extension is usually referred to as a mast. In turn, wings similar to hydrofoils are attached to it. At a certain speed, the wings lift the board out of the water through dynamic buoyancy.
For spectators, a foil board gives the impression that the surfer is floating over the water while wing foiling. This also creates the feeling of floating over the water for the passengers. The advantage is that the drag created by waves is reduced. This allows higher speeds. In addition, gliding with the hydrofoil is much quieter.
Due to their low water resistance in this driving mode, foil boards are particularly suitable for light winds or for races.
