An attempt of the specification of the ships navigation process

An attempt of the specification of main issues, such as the objectives, tasks, activities, etc. which are being solved and are being done while the ship is conducted at sea is undertaken in the paper. These issues constitute the substance of the ship’s navigation process and all its sub process. The authors’ belief is that the specification of these issues would enable the better understanding the matter of ship’s navigation process. It could also facilitate the preparation of more precise algorithms of all navigation sub processes, i.e. even those which hardly could be expressed by the means of mathematical relations.
