PROBLEM TO BE SOLVED: To provide a hull frictional resistance reducing apparatus and a ship, which are configured to effectively reduce the frictional resistance of a hull while suppressing risks associated with flowing of bubbles into a propeller.SOLUTION: A hull frictional resistance reducing apparatus comprises: a plurality of bubble jetting units 36C, 36R, 36L that are provided in the width direction forward of a propeller 16; adjusting mechanisms 35 that adjust the jetting amounts of bubbles from the bubble jetting units 36C, 36R, 36L; a control device 50; and inflow information acquisition means 40 for acquiring information relating to inflow of bubbles 100 into the propeller 16. The control device 50 has an adjusting mechanism control part 52, and upon acquiring the bubble inflow information from the inflow information acquisition means, the adjusting mechanism control unit 52 controls operation of the adjusting mechanisms 35 in such a manner that the jetting amount of the bubbles 100 with respect to at least the bubble jetting unit 36C disposed forward of the front face of the propeller 16 is reduced.SELECTED DRAWING: Figure 2

    【課題】プロペラへの気泡の流入によるリスクを抑制しつつ船体の摩擦抵抗を効果的に低減することができるようにした、船体摩擦抵抗低減装置及び船舶を提供する。【解決手段】プロペラ16よりも前方に幅方向に複数設けられた気泡噴出ユニット36C,36R,36Lと、気泡噴出ユニット36C,36R,36Lの気泡噴出量を調整する調整機構35と、制御装置50と、プロペラ16への気泡100の流入に関する情報を取得する流入情報取得手段40とを備える。制御装置50は調整機構制御部52を有し、調整機構制御部52は、前記流入情報取得手段から前記気泡流入情報を取得した場合には、少なくとも、プロペラ16の正面前方に配置された気泡噴出ユニット36Cについて、気泡100の噴出量を減少させるように調整機構35の作動を制御する。【選択図】図2
