Provided is an ammonia-propelled vessel which may comprise: a hull; a first fuel tank installed on the hull and storing liquid ammonia; a combustion engine generating power by burning the liquid ammonia supplied from the first fuel tank; a first fuel supply pipe connecting the first fuel tank and the combustion engine; an exhaust pipe discharging exhaust gas generated in the combustion engine; a selective catalytic reduction reactor installed on the exhaust pipe and reducing nitrogen oxide contained in the exhaust gas; and an ammonia evaporation gas supply pipe supplying ammonia generated by vaporization of the liquid ammonia in the first fuel tank to the selective catalytic reduction reactor. The ammonia-propelled vessel is capable of efficiently treating a boil-off gas of the liquid ammonia.
