The two dimensional theory of cavity flows under ship bottoms is based on the linear theory of wave motions of ideal incompressible fluid. The cases of high speed and displacement ships are considered. In the case of high speed ship the problem of planing hull with step and cavity at free fixing of trim angle and draft, unknown shape and length of cavity and wetted borders of hull is solved. The possibilities of modeling of ship hydrodynamic characteristics changing with the help of cavity pressure control are shown. A reduction of the wave resistance can be a result of such changes. In the case of displacement ship the cavitation flow model behind wedge under solid wall is considered. It is shown that the gravity waves with decreasing amplitude on cavity boundary are generated if the cavity on the horizontal wall is closed. In theoretical model, the existence of countable number of cavity lengths is possible. The characteristics of cavity shapes at negative cavitation numbers are determined.
