A ship drive system includes a first and one second drive shaft for driving a respective propulsion unit, wherein each of the electric drive shafts includes at least one speed-variable generator driven by an internal combustion engine for generating a motor voltage having a variable amplitude and variable frequency, and at least one speed-variable drive motor that is supplied with the voltage and coupled to the propulsion unit. The first and second drive shafts can be switched from a first operating state, in which they are electrically disconnected from each other, to a second operating state, in which they are electrically coupled to each other such energy can be transmitted from the at least one generator of the one drive shaft to the at least one drive motor of the other drive shaft. To this end, the at least one generator includes a superconductor winding.
