Abstract
(EN)
A ship is provided with: a first ship bottom (21) which is sloped upward and rearward from the ship bottom (13) located on the centerline (C) of the ship body (11) in the width direction thereof; and a second ship bottom (22) which is interconnected with the first ship bottom (21) at a position separated forward from the stern end (12a) by a preset predetermined distance (L) and which has a tilt angle greater than or equal to the angle of a line extending parallel to or tilted upward from a planned water line (S) and less than the angle of a line tilted downward from a line extending rearward from the first ship bottom (21). The configuration can reduce the resistance of the ship body during navigation.

L'invention concerne un navire qui est doté de : une première partie inférieure de navire (21) qui est en pente vers le haut et vers l'arrière à partir du fond du navire (13) située sur l'axe (C) du corps de navire (11) dans la direction de la largeur de celui-ci ; et une seconde partie inférieure de navire (22) qui est interconnectée avec la première partie inférieure de navire (21) à une position séparée vers l'avant par rapport à l'extrémité de poupe (12a) d'une distance prédéterminée préfixée (L) et qui a un angle d'inclinaison supérieur ou égal à l'angle d'une ligne s'étendant parallèlement à ou inclinée vers le haut à partir d'une ligne d'eau plane (S) et inférieur à l'angle d'une ligne inclinée vers le bas à partir d'une ligne s'étendant vers l'arrière de la première partie inférieure de bateau (21). La configuration peut réduire la résistance du corps du navire pendant la navigation.
(JA)
 船舶において、船体(11)の幅方向中心線(C)の位置にある船底(13)が後方へ上方傾斜した第1船底(21)と、船尾端(12a)から予め設定された所定距離Lだけ前方へ移動した位置で第1船底(21)に連続して計画喫水(S)に平行をなす角度以上で第1船底(21)からの後方延長線の角度より小さい角度をなす第2船底(22)とを設けることで、航走時における船体抵抗の低減を可能とする。
