Motor boat with foils which are retractable by tilting

A foil boat having a main axis in a driving direction comprising:

• a boat hull;
• and
• a pair of foils arranged one on each side of the boat hull, each foil of the pair of foils including a wing and a support,
• wherein each support is slidable relative to the boat hull, and at least partially retractable into the boat hull, such that the pair of foils are configured to adopt a first, active position where the pair of foils are deployed in similar positions, and a second, passive position in which each support is at least partially retracted into the boat hull, and
• wherein a displacement of the pair of foils from the second, passive position to the first, active position includes an initial sliding displacement of each support in a direction away from the boat hull, the direction diverging from a vertical median plane of the boat hull, followed by rotation motion about an axis that is parallel or substantially parallel to the main axis of the foil boat, such that an angle of the wings increase relative to the vertical median plane to move the wings closer to a horizontal position,
• wherein the direction of the initial sliding displacement away from the boat hull forms a curved trajectory.

• wherein the support of each one of the foils has a curved shape, and the direction of the initial sliding displacement of the support away from the boat hull forms a curved trajectory along the curved shape of the support.

• wherein the support is not movable relative to the wing of each one of the foils.
