PROBLEM TO BE SOLVED: To provide a ship which inhibits turbulent flow from occurring in a water lock to achieve improvement of the exhaust gas discharge efficiency, and to provide an exhaust structure for the ship.SOLUTION: An exhaust structure 20 of a ship including an engine includes: an upstream exhaust pipe 21 having a tip part 21A formed with an outlet 21D; a water lock 22 having an internal space 22G which houses the tip part 21A; a downstream exhaust pipe 23 connected with the water lock 22; and a dam part 25 serving as one example of a flow direction conversion member. The upstream exhaust pipe 21 guides an exhaust gas from the engine to the tip part 21A. The downstream exhaust pipe 23 discharges the exhaust gas flowing from the outlet 21D into the internal space 22G to the outside of a boat hull. The dam part 25 converts an exhaust gas flow direction to an intersection direction Y2 intersecting with a pipe axis A of the tip part 21A at the outlet 21D.SELECTED DRAWING: Figure 2

    【課題】ウォーターロック内における乱流の発生を抑制して排気ガスの排出効率の向上を図れる船舶、および、船舶のための排気構造を提供する。【解決手段】エンジンを備えた船舶の排気構造20は、出口21Dが形成された先端部21Aを有する上流排気管21と、先端部21Aを収容した内部空間22Gを有するウォーターロック22と、ウォーターロック22に接続された下流排気管23と、流れ方向変換部材の一例としての堰き止め部25と、を含む。上流排気管21は、エンジンからの排気ガスを先端部21Aまで導く。下流排気管23は、出口21Dから内部空間22Gに流入した排気ガスを艇体の外に排出する。堰き止め部25は、出口21Dにおいて、先端部21Aの管軸Aと交差する交差方向Y2へと排気ガスの流れ方向を変換する。【選択図】図2
