PURPOSE: A semi-submerged hydrofoil craft is provided to reduce wave drag by forming the knife type edge and a streamlined side in the support, and to improve stability by reducing resistance against water with hydrofoils. CONSTITUTION: A semi-submerged hydrofoil craft is composed of a hull(20) floating on the water in cruising; a submerged hull(40) placed below the surface of water; and a ship body having single or plural supports connecting the hulls vertically. The submerged hull is composed of a water suction port(51) absorbing water from the front, a propeller sucking water from the water suction port and discharging water backward, a water injection port opening and injecting water from the propeller, a water supply passage(52) connected from the back of the propeller to the water injection port, and foils mounted to both sides of the submerged hull.
