To provide a vessel equipped with a navigation stabilizer capable of securing a function even during navigation of the vessel and a water shielding device provided in the vessel in a composition obtaining additional buoyancy by expanding a buoyancy body.SOLUTION: A vessel includes: at least one pair of recesses 11 provided in an arrangement which is symmetrical to a hull center line CL in an immersed area below a load water line of a bottom shell plating 21 and extending in a longer direction of the vessel; a buoyancy body 13 provided inside the recesses 11 and generating buoyancy by expanding outside the bottom shell plating 21 by having gas supplied inside; a gas supply unit 30 for supplying compressed air to the buoyancy body 13; a water shielding unit 12 provided to allow posture change between a projecting position projecting more outside the bottom shell plating 21 and a stored position more inside than the bottom shell plating 21 on an edge unit on the bow side of the recesses 11 and shielding a water flow affecting the buoyancy body 13 during navigation of the vessel by being positioned on the projecting position; and a control unit 50 for controlling supplying of compressed gas by the gas supply unit 30 and posture change of the water shielding unit 12.SELECTED DRAWING: Figure 3
【課題】浮力体を膨張させて付加的な浮力を得る構成において、船舶の航行中においても機能を確保することができる運航安定装置を具備する船舶及び船舶に備えられる遮水装置を提供する。【解決手段】船底外板21の満載喫水線よりも下方の没水領域に船体中心線CLについて対称かつ船体の長手方向に延びた配置で設けられた少なくとも1対の凹部11と、凹部11内に設けられ内部に気体が供給されることにより船底外板21よりも外側まで膨張して浮力を発生する浮力体13と、浮力体13に圧縮空気を供給する気体供給部30と、凹部11の船首側の縁部に、船底外板21よりも外側に突出した突出位置と船底外板21よりも内側の収納位置との間で姿勢変更が可能に設けられ、突出位置に位置して船体の航行時に浮力体13に作用する水流を遮蔽する遮水部12と、気体供給部30による圧縮気体の供給および遮水部12の姿勢変更を制御する制御部50とを備える。【選択図】図3
