A water conveyance having two hull members spaced from each other and carrying a hydrofoil toward the stern thereof and an airfoil or wing toward the bow. The hydrofoil and airfoil cooperate to lift the hull members from the water to reduce water resistance and increase travel speed. The hydrofoil is movable vertically to accommodate the raising and lowering of the hull members during start up and slow down. Flaps on the wing control the attitude of the conveyance and, in a preferred embodiment, the flaps are controlled automatically to maintain a generally horizontal attitude.
