PROBLEM TO BE SOLVED: To improve freedom in design by reducing composing members arranged inboard as well as suppressing strength degradation at a bottom in a friction reduction device for a vessel.SOLUTION: A friction reduction device is provided with: an air supply device 32 provided inside a hull 10; a passage member (air passage) 41 as an air blowing out unit 35 provided along a vessel width direction outside a bottom 13; a plurality of air blowing out openings 44 provided with prescribed intervals in the longitudinal direction of the passage member 41; and an air supply pipe 34 for connecting the air supply device 32 and the passage member 41 inboard.SELECTED DRAWING: Figure 3

    【課題】船舶の摩擦低減装置において、船内に配置する構成部材を削減して設計の自由度を向上させると共に船底の強度低下を抑制する。【解決手段】船体10の内部に設けられる空気供給装置32と、船底13の外側に船幅方向に沿って設けられる空気吹き出し部35としての通路部材(空気通路)41と、通路部材41の長手方向に所定間隔を空けて設けられる複数の空気吹き出し口44と、空気供給装置32と通路部材41とを船内で接続する空気供給配管34とを設ける。【選択図】図3
