In the last years, the size and the number of ships has grown remarkably. At the same time, the size of harbors and ports remain constantly. Asa result, the ship maneuvering in harbors has become more problematic and harder to execute. This is the reason that many sailors affirm that it is an art than a science to execute some maneuverings. Ship maneuvers represented a complex vessel motions influenced most of the time by external environmental conditions in the navigation area (i.e. ocean and tidal current conditions, water depth, wind and waves). Navigator`s knowledge and experiences overcome to control the ship speed, course and heading in some close encounter situations. For example, combinations of different environmental conditions (draft variations in a passage from fresh to sea water with other ships near the same navigation area), create not only additional navigation difficulties, but also could compromise and threatens the navigation.
