ABSTRACT An hydrofoil assembly for small craft is disclosed. The assembly includes two hydrofoils independently mounted on a boat or a propulsion unit of the boat's motor for free pivotal movement between a depending position and a extended in-use position. The foils automatically adopt the in-use position during forward movement and drop to their depending positions whenever their angle of attack becomes negative, such as in reverse movement when pivoted up to clear an obstacle, or when the boat is stationary.
