Device for providing electrical power for an electrical consuming device and/or for charging a battery in a boat

A device, comprising:

• a combustion engine having an engine regulator for regulating the combustion engine;
• a direct current generator, which is coupled to and operated by the combustion engine, and which has a generator regulator for regulating the direct current generator, wherein the direct current generator provides electric power to an electrical consuming device of and/or charges a battery of an on-board electrical system of an electric-motor powered boat;
• and
• a control device configured to set an engine reference variable for the engine regulator and a generator reference variable for the generator regulator, wherein the engine reference variable and the generator reference variable are set independent of one another,
• wherein the control device is configured to set, for a specific power range, the engine reference variable in the form of a constant speed setting on the basis of a power demand in the on-board electrical system and to increase the constant speed setting when the specific power range is exceeded,
• wherein the control device is configured to set a generator reference variable in the form of a voltage setting, current setting or power setting on the basis of the power demand in the on-board electrical system at a constant speed setting, and
• wherein the control device provides the engine regulator with the constant speed setting as the engine reference variable and provides the generator regulator with the voltage setting, current setting or power setting as the generator reference.
