Claim:
A self-propelled ship, the ship comprising at least a first shipboard electric network, at least one main electrical supply bus, a propulsion device, at least one drive motor for driving the propulsion device, and a generator operably supplying electricity to the first shipboard electric network and the at least one drive motor through the main electrical supply bus, wherein: the generator further comprises at least one set of electric capacitors having a capacitance sized so as to provide, at their nominal electrical charge, at least temporarily, both a nominal supply of the at least one first shipboard electric network and a nominal electrical supply of the at least one electric drive motor through the main electrical supply bus; and an electrical connector arranged on board the ship connecting the set of electric capacitors to another electric network located at at least one point selected from: (a) an arrival point and (b) a departure point, of the ship, for the purpose of recharging the capacitors to their nominal charge and to supply the first shipboard electric network during a stop at the point.
