Beschreibung
Zusammenfassung:	A drive for a boat, in particular a sailing boat, comprising an electric motor configured for the operation in the first quadrant and in the fourth quadrant, a propeller connected to the electric motor, and a control device. The control device is configured to operate the electric motor in the fourth quadrant in such a way that flow energy transmitted via the propeller to the electric motor is regenerated into electrical power. The control device is further configured to operate the electric motor such that a product of the propeller's pitch and rotational speed is smaller than a relative flow speed between the water and the drive.
