The problem of identifying a mathematical model of a ship considered in this paper is easily immersed in the general problem of modeling and identifying models. From a general standpoint, the main content of sciencec an be recognized as the formation of models of one type or another based on the results of observations and the study of their behavior. Models can be formalized to varying degrees, but they all have one main property - they link observations into some general picture. Solving the problems of constructing mathematical models of dynamic systems based on observational data on their behavior is the subject of identification theory.

When controlling a modern vessel while moving on a course and under the condition of an integrated bridge satu-rated with instruments, the skipper does not pay enough attention to the analysis of a complex navigational situa-tion, which leads to a chaotic and unpredictable passage of the route. The method of estimating the spectral densi-ty of stochastic processes in the problems of identification, filtering and forecasting of ship management when solving issues of assistance in decision-making by the boat master in navigation and control actions and route op-timization is investigated. The prediction of a stochastic process in real time is investigated on the basis of the ob-tained spectral density estimate, the results of modeling on a ship computer, the convergence rate and the accura-cy of the solution of the problem. The paper also substantiates the need for the formation of stochastic thinking at the future navigator, which allows, based on intuitive and logical thinking, to abandon at the initial stage of solving a problem from deliberately false options for the development of the process in order to ensure the safety of navi-gation.

The article presents an analysis of ways to control the motion parameters of a towed vessel, which is part of the towing system, by adjusting the tension and (or) length of the towing cable during the towing operation. The analysis is based on the results of model experiments using a mathematical model of a towed vessel and a towing cable. Based on systematic analysis of the process of movement of a towed vessel, the main dependences of the values of the kinematic parameters of its movement were identified when adjusting the tension and length of the towing cable, and the most effective method of regulation was established.
