Synthesis of automatic control systems (ACS) of spatial motion of underwater systems with flexible connections (USFC) forms the actual scientific problem. Own nonlinearity remotely operated underwater vehicle (ROV) enhanced nonlinearity flexible connections that make up USFC. Synthesis of ACS and USFC link forms the basis for automatic control of both onelink and multilink USFC. The method of the formalization of USFC structure is in the form of a graph model. It is represented on the basis of defined-controlled units of USFC. The method of inverse dynamics is synthesized from the regulators spatial movement of TPA and cable winches to control the length of the flexible part of the issued bonds. A BAC USFC link, which includes TPA, a cable winch and synthesized regulators, is the basis for the automation of spatial movement of onelink and multilink USFC. Computer simulation work of NAO investigates USFC link. The result is quite satisfactory for the automatic management of objects of such complexity.

During the last decades a vast amount of research has been focused on the issues of design, operations, and development of more optimized structures of high-speed craft. The right choice of the criterion function is crucial. Fundamentally, efficiency can be increased with the reduction of production costs, operational costs, and environmental impact, while maintaining or improving craft performance, reliability, and safety. The estimation of economic performances of pilot boats in conceptual design phase should account for many features, such as, different building materials, development of the hull design, choice of the propeller, conditions of operations, and others. The majority of estimation techniques are developed specifically for large ships and, therefore, do not take into account the essential features of design and function of small high-speed craft, namely, pilot boats. Іn this paper we present formulas for estimation of building cost of the conventional pilot boat (a monohull). The author recommends the set of formulas for estimation, which form the mathematical model. These equations can be used in the optimization task.
