Disclosed is a direct current networking power system for a waterborne vessel, the system comprising a port-side propulsion unit and a starboard-side propulsion unit. The propulsion units include a direct current bus, and the direct current bus is connected to at least two generator-based power supply mechanisms and a waterborne vessel propulsion mechanism. The direct current bus on the port side or the starboard side is provided with a load mechanism. An electronic power switch is provided between direct current buses on the port side and the starboard side. The power system for a waterborne vessel is provided with a means for isolating a portion of a load if the portion is short circuited. If a short circuit occurs at a certain location, the power system is capable of immediately isolating a short circuit source by means of short circuit support, thereby preventing the short circuit at the certain location from paralyzing the entire power system of the waterborne vessel, and improving the safety and redundancy of the system. Further disclosed is an operation- and power-optimized control method for the direct current networking power system for a waterborne vessel. The method improves power allocation accuracy of a power generator unit, and ensures that the power generator unit is running in a most fuel-efficient state.
