To provide an energy saving device for a vessel with easy execution to the vessel as well as being capable of markedly reducing wave resistance.SOLUTION: An energy saving device for a vessel includes an additional member installed to a stern part of a drainage volume type vessel with sea speed of FN (Froude number) 0.13 to 0.5, the additional member closely abuts on the stern part and is distributed over substantially the entire width at a stern end of the vessel. The additional member is formed extending from a portion closely abutting on the stern part and a lower part of the additional member shows a horizontal surface. The horizontal surface is positioned above a full load designed draft surface and is at a distance of maximum 1.5%Lpp (length between perpendiculars) from the full load designed draft surface.SELECTED DRAWING: Figure 1

    【課題】船舶への実施が容易且つ造波抵抗を顕著に低減できる船舶用省エネ装置を提供すること。【解決手段】航海速力がFN(フルード数)0.13~0.5の排水量型船舶の船尾部に設置する付加部材を備え、前記付加部材が前記船尾部に密接に当接し、且つ前記船舶の船尾端のほぼ全幅にわたって分布され、前記付加部材は前記船尾部に密接に当接する箇所から延伸形成し、且つ前記付加部材の下方は水平面を呈し、前記水平面は満載計画喫水線面の上に位置し、前記満載計画喫水線から最大1.5%Lpp(垂線間長さ)の距離にあることを特徴とする、船舶用省エネ装置。【選択図】図1
