Paper extends the theory of Gerstner waves by the addition of a fluid layer in rigid body motion above the surface of the conventional Gerstner wave field. The propagation speed is then decreased by a factor of Square root of Delta RHORHO. The same result is also valid for the system turned upside down with a reversal of the density difference. Combining the flows, one can also construct a three-fluid system with a middle layer in uniform motion in the plane of Gerstner waves, while the flow normal to this plane can be arbitrary and must be steady.
