摘要： A ship of a displacement type with a pointed bow and a transom stern, a longitudinal length of L, and defining a base plane and a design waterline plane, the ship comprising: approximately sinusoidal waterlines; a surface extending from the transom stern at the design waterline plane to the base plane at about L/2 and defining an angle between: the base plane and an oblique plane, the oblique plane being defined by: a line at the intersection of the transom stern and the design waterline plane and a point located on the surface at about 0.2L from the transom stern, and a first propeller which is attached to the ship so that the hull wake through the first propeller is less than 0.50. A ship of a displacement type with a transom stern, a longitudinal length of L, and defining a base plane and a design waterline plane, the ship comprising: approximately sinusoidal waterlines; and a surface extending from the transom stern at the design waterline plane to the base plane at about L/2 and defining an angle between: the base plane and an oblique plane, the oblique plane being defined by: a line at the intersection of the transom stern and the design waterline plane and a point located on the surface at about 0.2L from the transom stern; a first propeller which is attached to the surface of the ship near a first corner of the transom stern; and a second propeller which is attached to the surface of the ship near a second corner of the transom stern. A ship of a displacement type with a pointed bow and a transom stern, a longitudinal length of L, and defining a base plane and a design waterline plane, the ship comprising: approximately sinusoidal waterlines; and a surface extending from the transom stern at the design waterline plane to the base plane at about L/2 and defining an angle between: the base plane and an oblique plane, the oblique plane being defined by: a line at the intersection of the transom stern and the design waterline plane and a point located on the surface at about 0.2L from the transom stern, and a first propeller wherein an axis of the first propeller is substantially parallel to the base plane of the ship.
