Abstract
Improvements in the shape of the hull of ships in relation to their efficiency from the hydrodynamic point of view, characterized in that referring to single-propeller boats the length-to-width ratio is not greater than 6.5: 1, with a block coefficient of not less than 0.80 and a bulb in the tajamar, said bulb having a maximum transverse area equal to, approximately, 10% of the submerged cross-sectional area of the hull in its average length, having the shape of the simple hull curvature in the lines of the curved stern planes extending from the stern of the ship to approximately 19 to 25% of the length of the ship measured along the base line of the galibo in the longitudinal centerline, and an appendix supporting the propeller below the stern of the ship at the longitudinal center line, said appendage having a narrow V-shaped cross section and gradually tapering in the direction towards behind.
