To provide a hull shape of a cargo vessel capable of improving propulsion performance of the vessel while retaining cargo loading possible area maximum with its width substantially same as the beam.SOLUTION: A hull structure in a cargo vessel with respective side walls of both starboard and port sides of bow side inner cargo hold having perpendicular positional relation with respect to a deck 10 immediately above an inner bottom plate 2 and provided with expanded parts on a hull outside plate portion corresponding to corners in the vicinity of an inner bottom plate part of a front end of the inner cargo hold in a hull outer plate. The expanded parts 17, 18 comprises perpendicular plate parts 13, 14 and curved plate parts 15, 16 formed inclined continuously to the perpendicular plate parts. The perpendicular plate parts are configured to have a positional relation with a 90° angle with respect to the inner bottom plate or the deck and to be used also as side walls of both starboard and port sides corresponding to the inner cargo hold. The curved plate parts straddle the inner bottom plate positioned on the front end of the inner cargo hold, and expand outward in a range from below the vicinity of the inner bottom plate part to the bow side of the inner cargo hold. A bottom end edge and a front end edge of the perpendicular plate parts are provided continuously with the curved plate part to form each of the expanded parts.SELECTED DRAWING: Figure 4

    【課題】貨物積載可能面積を船幅と略同じ最大限に保持しつつ、かつ船舶の推進性能を向上可能な貨物船の船体形状を提供する。【解決手段】船首側内部貨物倉の左右両舷側の夫々の側壁が内底板2の真上の甲板10に対して垂直な位置関係を有し、船体外板のうち内部貨物倉前端の内底板部付近の角部に対応する船体外板部分に膨出部を設けた貨物船における船体構造において、膨出部17、18は、垂直板部13,14と、該垂直板部に対して内傾して連設する彎曲板部15、16とよりなり、垂直板部は内底板或は甲板と90°の角度を有する位置関係に設定され、且つ、内部貨物倉の対応する左右両舷側の側壁と兼用され、彎曲板部は内部貨物倉前端より船首側に位置する内底板を跨り、内底板部付近より下側から内部貨物倉の船首側に亘る範囲に於いて外側方に膨出し、垂直板部の下端縁と前端縁が、彎曲板部と連続的に設けられて膨出部を形成する。【選択図】図4
