Device for propelling and turning hull

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.
