Abstract: A method and a device can be used to transmit data onboard a watercraft using an onboard power supply network. A central control unit generates an instruction for a first consumer module. The instruction is transmitted from the central control unit via a first control unit-head station data connection to a first head station. The first head station converts the instruction into an instruction signal that is transmittable via the power supply network. The instruction signal is transmitted from the first head station via a first head station-power line data connection, the power supply network, and a first coupling module-power line data connection to a first coupling module. From the instruction signal, the first coupling module again generates an instruction that can be transmitted via a data connection. The instruction is transmitted from the first coupling module via a first coupling module-consumer data connection to the first consumer module.
