The invention relates to the technical field of ship power systems, and provides a ship steam power system and a ship. The ship steam power system comprises a steam pipeline, a direct mixing condenser, a first pipeline, a steam generator and a second pipeline, the direct mixing condenser and the steam generator form a circulation loop through the first pipeline and the second pipeline, an inlet of the steam pipeline is connected with the steam generator, and an outlet of the steam pipeline is connected with the direct mixing condenser. A first mixed working medium is arranged in the direct mixing condenser, and the equivalent specific heat capacity of the first mixed working medium is larger than that of water. According to the ship steam power system, the characteristic that the equivalent specific heat capacity of the first mixed working medium is larger than that of water is utilized, a large amount of heat is absorbed when the first mixed working medium and the water are subjected to hydration reaction, the heat transfer efficiency of the ship steam power system is improved, the heat exchange end difference is reduced, and the vacuum degree of the direct mixing condenser is easy to control; and safe operation of the ship steam power system is ensured.
