摘要： A method and a controller unit (110) for controlling motion of a watercraft (120) with a hydrofoil (130) are disclosed. The controller unit (110) obtains (A010) information indicating shape of water surface in front of the hydrofoil (130). The controller unit (110) further predicts (A040) wave acceleration of the watercraft (120) using a neural network. Furthermore, the controller unit (110) determines a target route and corresponding total acceleration of the watercraft (120) under a set of constraints. The total acceleration is minimized when the watercraft (120) travels according to the target route. The set of constraints includes: a first constraint that the hydrofoil (130) stays within an interval relative to the water surface, and a second constraint relating to magnitude of acceleration derived from maximum AoA and the predicted wave acceleration. The controller unit (110) calculates an AoA for the target route. Next, the controller unit (110) sends a signal for adjusting the hydrofoil (130) according to the AoA. A corresponding computer program (403) and a computer program carrier (405) are also disclosed.

摘要： The invention involves a boat comprising
- a hull (2),
- a hydrofoil (301, 601) mounted to the hull (2) by means of a hydrofoil holding arrangement (302) comprising a strut (3021, 503),
- wherein the boat comprises a strut adjustment arrangement (310, 510) arranged to retract the strut (3021, 503) from an extended position to a retracted position so as to move the hydrofoil (301, 601) from a deployed position to a restrained position, and/or to lock the strut in the extended position and/or in the retracted position,
- wherein at least a portion of the strut has a hydrodynamic portion forming a leading edge (5036) and a blunt trailing edge (5037), wherein a sheltered portion (5101', 5104, 5108) of the strut adjustment arrangement is positioned, and/or arranged to be positioned, so that an extension of the sheltered portion in a longitudinal direction of the strut is within an extension of the blunt trailing edge in the longitudinal direction of the strut, and so that the sheltered portion is located behind the blunt trailing edge as seen in the direction of straight forward travel of the boat, and/or in one or more cavities in the hydrodynamic portion, which one or more cavities (5111) extend from the blunt trailing edge.
