PROBLEM TO BE SOLVED: To provide a ship in which reduction in a living area or a cargo loading area is suppressed without increasing the total length of a hull and a propulsion performance can be improved, when a Froude number is 0.25 to 0.38.SOLUTION: A ship 1 has a Froude number of 0.25 to 0.38, and comprises: a bow valve 7 arranged below a load line and having an upper end arranged at or higher than lightest load line; and a stem 8 having a front end 8a extending vertically upward from the front end 7a of the bow valve 7.SELECTED DRAWING: Figure 2
【課題】フルード数が0.25から0.38の場合に、船体の全長を増加させることなく、居住区や貨物積載部の縮小を抑制すると共に、推進性能を向上することができる船舶を提供する。【解決手段】船舶1は、フルード数が0.25から0.38の船舶であって、満載喫水線よりも下方に配されて上端部が最軽荷喫水線以上に配される船首バルブ7と、船首バルブ7の前端部7aから鉛直上方に向かって延びる前縁部8aを具備するステム8と、を備える。【選択図】図2
