To provide a propulsion resistance reduction device for a ship which has versatility as the propulsion resistance reduction device regardless of the size, the speed, the propulsion system, and the steering function of the ship, and has significant improvement effect at low implementation cost by effectively recovering energy of a V-shaped wave generated at a stern.SOLUTION: A sailing resistance reduction device for a ship is provided with an almost horizontal fin-shaped member projecting to left and right fixed at a stern of a hull. The planar shape of the fin-shaped member is formed so that a tip of its leading edge faces slightly backward. The fin-shaped member is formed so that the cross section of the leading edge is a little thick and faces downward, and that the cross section of a trailing edge is thin and faces horizontally.SELECTED DRAWING: Figure 3
【課題】本発明が解決しようとする課題は、船尾に発生するV字波のエネルギーを有効に回収して、船舶の大きさ、速度、推進方式、操舵機能に関係なく、推進抵抗削減装置としての汎用性を備え安価な実施費用で大幅な改善効果のある船舶用の推進抵抗削減装置を提供するものである。【解決手段】船体の船尾部に左右に張り出したほぼ水平方向のヒレ状部材を固着して設け、該ヒレ状部材の平面形は前縁の先端がやや後方を向くように形成され、断面は前縁部がやや厚く下方を向いて、後縁部が薄く水平方向を向いたごとき形状に形成されていることを特徴とする船舶用の航行抵抗削減装置を提供するものである。【選択図】図3
