SHIP WITH LITTLE WIND-PRESSURE RESISTANCE

WIPO Patent Application WO/2019/235281

A1

The present invention is configured such that, in a horizontal cross-section Sh(z) of above-water structures 2, 20, having a stern-side first range Rx1 and a vertical first range Rz1, a fan-shaped region Rα denotes the space between a first inclined line L1 that extends at a first angle α1 of 50° with respect to the bow direction Lc in the longitudinal direction X, and a second inclined line L2 that extends at a second angle α2 of 80°. A virtual point P2(z) of the pivot of the fan-shaped region Rα is positioned such that, when the virtual point P2(z) is moved forward or backward along a hull center line Lc, 50-100% of the length of a contour Ls(Z) of the horizontal cross-section Sh(z) falls within the fan-shaped region Rα. According to this configuration, a ship with little wind-pressure resistance can be provided, thereby reducing the effects of cross-head winds, generating lift in the above-water structures constituted by a ship hull or from an upper structure and loaded freight, making it possible to obtain thrust from the lift component in the longitudinal direction of the hull, and enabling improved propulsion performance of the ship.
