A method for operating a winch of a vessel and an electric drive for a winch, the winch comprising a rotatable winch drum (20) for spooling a spoolable medium (10), and an electric motor (30) to rotate the winch drum, wherein the electric drive (40) is configured to be operably coupled to the electric motor (30), and is configured to control, in response to a detected changing of a vertical position of the vessel (100), a length of the spoolable medium (10) between the winch drum (20) and a winched object (200) such that a magnitude of a change of a vertical position of the object (200) with respect to the reference vertical position resulting from the change of the vertical position of the vessel (100) with respect to the reference vertical position is reduced, thus providing active heave control.
