Abstract
The effect of changing the length of the ship's hull on its controllability and stability on the course is considered. The assessment is carried out according to the controllability diagram. A method of calculating and constructing a diagram based on a mathematical model of transient modes of propulsive complexes of ships with electric propulsion is proposed. The parameters affecting the controllability diagram were identified, and the degree of their influence was estimated. A method of constructing a controllability diagram with the possibility of analyzing the influence of propulsion complex parameters on maneuverability has been developed. The trends in the changes in the controllability of ships and their stability on the course when the structural parameters of the ship are changed have been determined. An analysis of the effect of changing the ship length on maneuverability was carried out. It is shown that lengthening the vessel up to 0.16 of is length does not significantly affect its maneuverability and stability on the course.
