To provide a vessel propulsion system and a vessel capable of stabilizing speed of the vessel and improving quietness of the vessel when the vessel is voyaging at lower speed than the speed in a state of trawl thrust, as well as reducing exhaust amount of carbon dioxide.SOLUTION: This vessel propulsion system 100 (vessel 110) includes a controller 50 for carrying out electric drive control for driving an auxiliary propeller 31 (auxiliary propulsion unit) having a smaller maximum output than a main propeller 21 with an electric motor 32 in an auxiliary propulsion machine 30 without carrying out engine drive control for driving the main propeller 21 (main propulsion unit) with an engine 22 in a main propulsion machine 20 when adjusting propulsion P of the vessel 110 so that propulsion P is less than trawl propulsion Ptrl .SELECTED DRAWING: Figure 8

    【課題】トロール推力の状態における速度よりも低速で船舶を航行する際に、船舶の速度を安定させること、および、船舶の静音性を向上させることが可能で、かつ、二酸化炭素の排出量を低減することが可能な船舶推進システムおよび船舶を提供する。【解決手段】この船舶推進システム100(船舶110)は、船舶110の推力Pをトロール推力Ptrl未満になるように調整する場合に、主推進機20においてエンジン22により主プロペラ21(主推進部)を駆動させるエンジン駆動制御を行わずに、補助推進機30において電気モータ32により主プロペラ21よりも最小出力が小さい補助プロペラ31(補助推進部)を駆動させる電動駆動制御を行う制御部50を備える。【選択図】図8
