In ship handling at a harbour, captains or pilots face to various ship handling scenes. In order to overcome these, they are required to derive the maximum maneuverability from the ship. The purposes of this paper are put on making clear from the geometrical and ship handling theoretical view-points about the minimum stopping maneuvering methods of two ships (a small training ship with bow and stern thrusters and a container ship under tug controlling), obtained by numerical solutions using the sophisticating non-linear ship maneuvering models and providing the fundamental data for actual maneuverings and future development of automatic ship's berthing system.
