Abstract: There is provided a propulsion and steering device installed below a sea level of outsides of right and left ship walls in a ship. The device includes a manifold that is installed at a bottom of a hull in a longitudinal direction, and drains water introduced into a bow toward a stern; a propulsion unit that has a lower end rotatably connected to an end of the manifold close to the stern within a 360-degree range, and is provided to laterally discharge water; and a steering unit that is rotatably coupled to an end of the propulsion unit close to the stern, and rotates the propulsion unit in an arbitrary direction by a rotational force exerted from an outside.

Abstract: The present invention relates to a device for propelling and turning a hull, wherein the resistance acting on the stem of the hull is converted and the hull can be moved not only in the forward and backward directions but also in the left and right directions so as to improve the mobility and evasion capacity of the hull. The device for propelling and turning a hull comprises: a manifold arranged in the lengthwise direction in the lower portion of the hull so as to discharge the water introduced at the stem side toward the stern side; a propelling means, the top of which is rotatably connected to the stern side end of the manifold, the propelling means being arranged so as to jet water in a lateral direction; and a steering means, which is rotatably coupled to the stern side end of the propelling means such that the steering means rotates the propelling means in a given direction by means of rotating force applied from an external source.
