An improved method and apparatus provide a control of the vessel maneuvering by a determination and displaying of the dangerous relative course zones, wherein the end of the vessel speed-vector should not be located for the object evasion tactic maneuvering and/or collision avoidance maneuvering and should be located for the object pursuit and/or interception tactic maneuvering. The apparatus comprises an object disposition evaluator, a control system, a dangerous criteria setting system, an initial data processor, at least one display and a dangerous relative course zone determiner, including an interface-signal distributor, a logic processor and signal distributor and a data processing system, comprising a trigonometric function processor, a summator, a multiplier-divider and a data processor. The dangerous relative course zones are displayed on at least one indicator, proving the operator with the possibility to evaluate the danger approach situation and instantly select the anti-collision maneuver for collision preventive maneuvering and/or select an optimal maneuver for the assigned vessel tactic maneuvering execution.
