Hydrofoil Takeoff and Landing with Multiple Hydrofoils

A craft comprising:

• at least one hull;
• at least one wing;
• a front hydrofoil connected to the at least one hull;
• a rear hydrofoil connected to the at least one hull;
• at least one processor;
• and
• tangible, non-transitory computer-readable media that comprises program instructions executable by the at least one processor to cause the craft to:
• operate in a hydrofoil-borne mode comprising:
• the craft accelerating while both the front hydrofoil and the rear hydrofoil are each at least partially submerged in water;
• while the craft accelerates,
• positioning a control surface of the front hydrofoil such that the front hydrofoil exerts a first downward lift force on the craft, and
• positioning a control surface of the rear hydrofoil such that the rear hydrofoil exerts a second downward lift force on the craft;
• while both the front hydrofoil and the rear hydrofoil are each at least partially submerged in the water, determine that at least one takeoff condition is met;
• and
• after determining that the at least one takeoff condition is met, initiating a transition of the craft from operating in the hydrofoil-borne mode to operate in a wing-borne mode at least in part by:
• positioning the control surface of the front hydrofoil such that the front hydrofoil exerts a first upward lift force on the craft and
• positioning the control surface of the rear hydrofoil such that the rear hydrofoil exerts a second upward lift force on the craft;
• and
• after initiating the transition of the craft, operate in the wing-borne mode, the wing-borne mode comprising:
• the craft flying while neither of the front hydrofoil and the rear hydrofoil are submerged in the water.
