The article provides an analysis of the foundations of wing-in-surface-effect ship (WISE) development and describes the experiments conducted using the constructed three radiocontrolled and one virtual model of the WISE. The main problems identified during the experiments are de-scribed, as well as further prospects for the development of the project.

The article illustrates the methodological study basis of the multi-frequency (packet) spectrum of sea waves in the influence on the associated system “ship-outboard complex of geophysical equipment”. The selection of the main harmonic of vibrations in the spectrum allows us to implement a compensator of the outboard system according to the stability conditions determined by the Morlet polynomials obtained from the decomposition of the observed dynamics of the system.
