This invention discloses a novel ship design especially suitable for ocean-going merchant vessels and oil tankers. A ship is rendered into two or more independent ship bodies, and these separate ship bodies are joined together by means of hinge; thus the name sectioned ship. In one embodiment of the invention a sectioned ship comprises a fore ship body and an aft ship body, and, by means of a hinge means located in the middle part, i.e., the adjoining surface of said two ship bodies, the two ship bodies are vertically pivotably joined to form a ship. In another embodiment of the invention, a sectioned ship comprises a fore ship body, an aft ship body, and at least one intermediate ship body, and by means of two hinge means located at the two ends of the intermediate ship body these ship bodies are vertically pivotably connected to form a single body. The hinge means may be formed to be detachably separable with respect to the connected ship bodies, or it may be of a fixed, inseparable structure, said hinge means may also be formed of a box-body structure. In comparison with a conventional vessel of the same dimensions and under the same sailing condition, the sectioned ship can put up with about four times greater the stress and strain due to hogging and sagging, therefore, in ship-building, thinner steel plates can be used. And, if compared with a conventional vessel of the same structural strength, the sectioned ship can be made larger, which means ship's hold becomes greater, and less engine power and smaller propeller are needed, consequently resulting in less fuel as well as material cost.
