PURPOSE: A water gutter structure for a ship is provided to stabilize the ship operation, improve the ship speed, and prevent waste of the fuel. CONSTITUTION: A ship(1) comprises a body(23) having the buoyance, in which a steering house(22) is installed, a propeller(24) installed to a rear part of the bottom of the ship body so that a rotating force is applied from an engine, and a rudder(25). A water gutter(10) is combined with a lower part of the body rear by a hinge shaft to rotate. The water gutter is connected to a rod of a hydraulic device(13) installed in the ship body so that the rotation and angle of the water gutter are automatically adjusted according to the ship speed.
