The catamaran-type ship for hauling barges includes two parallel spaced hull forms each including its own bow. One or more additional bows, each partially defining a pair of water-receiving passageways respectively on opposite sides thereof, are disposed between the hull forms and extend rearwardly for only a portion of the length of the hull forms. An elongated platform structure for supporting barges in transit is disposed between the hull forms aft of the additional bow or bows. The platform structure extends rearwardly, from a front portion thereof adjacent the additional bow or bows, for a substantial portion of the remainder of the length of the hull forms, and is operatively connected to the hull forms for vertically reciprocal movement relative thereto. A pair of deflecting structures are disposed respectively on opposite sides of each bow to direct water from the water-receiving passageways downwardly and underneath the ship. The bows are flat on the bottom, sharply pointed, and have a leading edge which slopes upwardly and rearwardly from the tip of the bottom.
A ship structure comprising a pair of spaced, generally parallel, generally transversely aligned, elongated hull forms, a bow secured between the hull forms and having a front portion transversely spaced from each of the hull forms and partially defining a pair of water-receiving passageways respectively on opposite sides thereof, the bow extending rearwardly for only a portion of the length of the hull forms, an elongated platform structure disposed between the hull forms aft of the bow, and cooperative guide means at the inner sides of the hull forms and at opposite sides of the platform structure operatively connecting the platform structure to the hull forms for vertically reciprocal movement relative thereto, the bow including a generally flat bottom plate partially defined by a pair of convergent straight edges meeting substantially at a point, and the bow also including a first pair of generally triangular substantially identical side plates having base edges substantially collinear and coextensive respectively with the convergent edges of the bottom plate and each having a first side edge convergent with a respective one of the convergent edges of the bottom plate and substantially collinear and coextensive with a corresponding first side edge of the other.
A ship structure comprising a pair of spaced, generally parallel, generally transversely aligned, elongated hull forms, a bow secured between the hull forms and having a front portion transversely spaced from each of the hull forms and partially defining a pair of water-receiving passageways respectively on opposite sides thereof, and a pair of deflecting means disposed respectively on opposite sides of the bow and sloping downwardly and rearwardly substantially to the bottom of the bow to direct water in the water-receiving passageways downwardly when the ship structure is moving forwardly, the bow including a generally flat bottom plate partially defined by a pair of convergent straight edges meeting substantially at a point, and the bow also including a first pair of generally triangular substantially identical side plates having base edges substantially collinear and coextensive respectively with the convergent edges of the bottom plate and each having a first side edge convergent with a respective one of the convergent edges of the bottom plate and substantially collinear and coextensive with a corresponding first side edge of the other.
A bow for a ship, the bow comprising a generally flat bottom plate partially defined by a pair of convergent straight edges meeting substantially at a point and a pair of spaced generally parallel straight edges joined respectively to the convergent edges, a first pair of generally triangular substantially identical side plates having base edges substantially collinear and coextensive respectively with the convergent edges of the bottom plate and each having a first side edge convergent with a respective one of the convergent edges of the bottom plate and substantially collinear and coextensive with a corresponding first side edge of the other, and a second pair of generally triangular substantially identical side plates each having a first side edge substantially collinear and coextensive with a second side edge of a respective one of the first pair of side plates, each having a second side edge generally coplanar in a substantially vertical plane with a respective one of the parallel edges of the bottom plate and convergent therewith at a point where the respective one of the parallel edges of the bottom plate joins the respective one of the convergent edges of the bottom plate, and each having an upper base edge convergent with the upper base edge of the other of the second pair of side plates at a point where it converges with the first side edge of its respective one of the second pair of side plates.
