| Abstract: | A method of solving the problem of the motion of an elliptic contour in a three-layer fluid is developed within the framework
of the linear theory. The results of calculating the hydrodynamic contour loads and the shape of the interfaces are presented
for the following problems: the motion of a contour beneath an interface between two media and in a two-layer fluid both beneath
a rigid lid and a free surface. On the basis of the numerical experiment it is concluded that surface and internal waves have
a significant effect on the hydrodynamic characteristics of the contour.
