A device for inductively transmitting electrical energy between a power supply unit arranged on the shore of a body of water or in the body of water and a watercraft includes a primary coil associated with the power supply unit, and a secondary coil which is connectable to the primary coil for inductively transmitting electrical energy, and which is arrangeable on the watercraft. A height-adjustment device connected to the primary coil is provided in order to hold the primary coil at a consistent vertical distance from a water surface in a vertical direction running in the direction of the buoyancy. A corresponding charging system and method includes: aligning the coils relative to one another; previously or simultaneously adjusting a vertical distance between the primary coil and water surface by with a height-adjustment device; inductively transmitting electrical energy between the coils.
