The paper considers the features of determining the determination of the force and coefficient of water resistance to the movement of trawls and other floating bodies by the hydraulic-mathematical method by inverting the body contour based on the law of conservation of energy in the form of a solution in the special case of the Dido problem and the multi-criteria problem of the cal-culus of variations or optimal control in the general case. The proposed algo-rithm makes it possible to clearly take into account a wide range of hydro-mechanical phenomena that determine this important indicator, which is neces-sary for the development of an optimal trawling strategy.
