Abstract
A displacement ship for the transport selectively of low and high density cargo includes a hull having a trapezoidal cross-section and extending between the stem and stern of the ship. The sides of the hull form an angle of from 35.degree. to 55.degree. with the horizontal and extend upwardly above the design water line of the ship a distance at least equal to one-fourth the height of the hull. The upper extremities of the side walls of the hull terminate at the main deck of the ship which is coextensive lengthwise with the hull. At least one additional deck adapted to store low-density cargo thereon and coextensive in length and width with the main deck is positioned thereabove.
Claims5
A displacement ship for the transport selectively of low and high density cargo comprising:
- a hull which is substantially uniformly trapezoidal in cross-section and extends between stem and stern of the ship, said hull having downwardly and inwardly inclined side walls forming an angle of from 35.degree. to 55.degree. with the horizontal;
- a main deck surmounting said hull and coextensive lengthwise therewith, said side walls of the hull extending upwardly above the design water line of the ship a distance at least equal to one-fourth the height of the hull and terminating at said main deck;
- and at least one additional cargo deck coextensive in length and width with said main deck and positioned thereabove.
