To provide a vessel with little wind resistance reducing influence from oblique head wind, generating lift force on a water surface construction formed by the hull or a top structure and freight, obtaining propulsion force from components in front to back direction of the hull of this lifting force, and thereby improving the propulsion performance of the vessel.SOLUTION: A vessel is composed so that a virtual point P2(z) is in a position so that a counter line Ls(Z) which is a length 50% of a counter line Ls (Z) of a horizontal section Sh(z) or more and less than 100% is within a fan-shaped area (Rα) when the virtual point P2(z) which is pivot of this fan-shaped area Rα is moved from front to back along a hull center line Lc, when the fan-shaped area Rα is in between a first inclining line L1 extending at a first angle α1 which is 50 degrees to bow direction Lc in the front to back direction X and a second inclining line L2 extending at a second angle α2 which is 80 degrees, in each horizontal surface Sh(z) in a first range Rx1 on stern side of water surface structures 2, 20 as well as on top and bottom first ranges Rz1.SELECTED DRAWING: Figure 1

    【課題】斜め向かい風の影響を低減するとともに、船体又は上部構造物と積載貨物で形成する水面上構成物で揚力を発生し、この揚力の船体の前後方向の成分から推力を得ることできて、船舶の推進性能を向上できる風圧抵抗の少ない船舶を提供する。【解決手段】水面上構造物2、20の船尾側第1範囲Rx1かつ上下第1範囲Rz1における各水平断面Sh(z)で、前後方向Xの船首方向Lcに対して50度の第1角度α1で延びる第1傾斜線L1と、80度の第2角度α2で延びる第2傾斜線L2との間を扇形領域Rαとして、この扇形領域Rαの要の仮想点P2(z)を船体中心線Lcに沿って前後移動させたときに、水平断面Sh(z)の外形線Ls(Z)の長さの50%以上100%以下の長さの外形線Ls(Z)が扇形領域(Rα)に入るような仮想点P2(z)の位置があるように構成する。【選択図】図1
