Please refer to turning characteristics above, Origin ship position is white ship. Point of origin is Own Ship Bridge.
Green ship represents the end of first stage of turning where ship bow cannot leave original course line. This ship's length is about 230 meters; two ship's length is about 0.25 NM as the drawing above. This 0.25 NM distance is in while semi-circle lines.
We have some observations to note:
In the first stage (0.25 NM),
Own Ship is helpless in collision risk. Any rudder order (50, 100, 200,300 to port or starboard side) been used is useless. Vessels just collide with anything ahead. Own Ship can only hope for reducing the collision momentum by crash astern.
In the second stage (0.25 - 0.5 NM), Own Ship bow can clear original course line, but ship stern had not yet. More rudder order (50, 100, 200,300 to port or starboard side), more quick the bow deviate from original course line.Vessel may collide with her stern in this distance range.
In the third stage (0.5 - 0.75 NM),
Own Ship body can clear original course line, but the beam distance might not enough. More rudder order (50, 100, 200,300 to port or starboard side), more quick ship body deviate from original course line.
