Method for controlling the position of a hydrofoil, said hydrofoil comprising: - a hull extended along a main extension axis between a bow end and a stern end; - at least two appendages, rotatably mounted on said hull and projecting below with respect to said hull; said hull being provided with a median plane, comprising said main extension axis, and defining a port half-hull and a starboard half-hull (2"); said at least two appendages comprising at least one port appendage mounted on said port half-hull and susceptible of generating a first lift force and at least one starboard appendage (4") mounted on said starboard half-hull (2") and susceptible of generating a second lift force; - actuator means mechanically connected to said appendages in order to move them with respect to said hull; said control method being characterized in that it provides for: - a detection step, in which at least one flow sensor mechanically fixed to said hull detects at least one speed measurement of a water flow movable along a transverse direction that is tilted with respect to said main extension axis and generates a corresponding flow signal containing at least said speed measurement; - a first calculation step, in which an electronic control unit receives said flow signal and calculates, on the basis of the water flow speed, a corresponding difference of lift (ΔP) between the first lift force of said port appendage and the second lift force of said starboard appendage (4"); - a second calculation step, in which said electronic control unit calculates a movement position in which each said appendage is intended to be moved, in which said difference of lift (ΔP) is substantially zero; - a driving step, in which said electronic control unit generates a driving signal in order to drive said actuator means to move each said appendage around a corresponding first rotation axis orthogonal to said main extension axis; - a movement step in which said actuator means move each said appendage in order to reach the corresponding said movement position in an independent manner with respect to the other of said at least two appendages. - a hull extended along a main extension axis between a bow end and a stern end; - at least two appendages, rotatably mounted on said hull and projecting below with respect to said hull; said hull being provided with a median plane, comprising said main extension axis, and defining a port half-hull and a starboard half-hull (2"); said at least two appendages comprising at least one port appendage mounted on said port half-hull and susceptible of generating a first lift force and at least one starboard appendage (4") mounted on said starboard half-hull (2") and susceptible of generating a second lift force; - actuator means mechanically connected to said appendages in order to move them with respect to said hull; - a detection step, in which at least one flow sensor mechanically fixed to said hull detects at least one speed measurement of a water flow movable along a transverse direction that is tilted with respect to said main extension axis and generates a corresponding flow signal containing at least said speed measurement; - a first calculation step, in which an electronic control unit receives said flow signal and calculates, on the basis of the water flow speed, a corresponding difference of lift (ΔP) between the first lift force of said port appendage and the second lift force of said starboard appendage (4"); - a second calculation step, in which said electronic control unit calculates a movement position in which each said appendage is intended to be moved, in which said difference of lift (ΔP) is substantially zero; - a driving step, in which said electronic control unit generates a driving signal in order to drive said actuator means to move each said appendage around a corresponding first rotation axis orthogonal to said main extension axis; - a movement step in which said actuator means move each said appendage in order to reach the corresponding said movement position in an independent manner with respect to the other of said at least two appendages.
