A hydrofoil watercraft (1) is disclosed. The hydrofoil watercraft (1) comprises a hull (2), a hydrofoil (301) arranged to allow the hydrofoil watercraft (1) to be advanced in a foiling advancement in which the hull (2) is spaced apart from a water surface, and a hydrofoil adjustment arrangement (300) arranged to adjust an angle of attack of the hydrofoil (301) by a primary rotation of the hydrofoil (301) about a first rotation axis (R1) parallel with a pitch axis (Y) of the hydrofoil watercraft (1). The hydrofoil adjustment arrangement (300) comprises two struts (302, 303) connecting the hydrofoil (301) to the hull (2), and a respective truncated head (320), connecting each strut (302, 303) of the two struts (302, 303) to the hydrofoil (301), wherein the respective truncated head (320) is arranged to allow at least the primary rotation and a secondary rotation about a second rotation axis (R2) parallel with a roll axis (X) of the hydrofoil watercraft (1). The respective truncated head (320) is adapted to be accommodated within a width (D) of the respective strut (302, 303) at, and preferably along, the first rotation axis (R1) by that the respective truncated head (320) is truncated perpendicularly to the first rotation axis (R1).

A boat includes a hull (2), a hydrofoil (301, 601) mounted to the hull (2) by means of a hydrofoil holding arrangement (302) that has a strut (3021, 503). The boat also includes 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. At least a portion of the strut has a hydrodynamic portion forming a leading edge (5036) and a blunt trailing edge (5037), where a sheltered portion (5101′, 5104, 5108) of the strut adjustment arrangement is positioned.

A method and a controller unit for controlling motion of a watercraft with a hydrofoil) obtains information indicating shape of water surface in front of the hydrofoil. The controller unit further predicts wave acceleration of the watercraft using a neural network. Furthermore, the controller unit determines a target route and corresponding total acceleration of the watercraft under a set of constraints. The total acceleration is minimized when the watercraft travels according to the target route. The set of constraints includes: a first constraint that the hydrofoil 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 calculates an AoA for the target route. Next, the controller unit sends a signal for adjusting the hydrofoil according to the AoA.
