The planning for ports and coastal traits with marine yards can be summarized in three words: source, action, alternative. The source clarifies pontoons, cables, temporary buoys and means with limited manoeuvre capacity; the action modifies the route; the alternative avoids staying without choice.
Source
Consult the official act and avoid passing between the means of work and the coast without knowing submerged encumbrances or areas. Check that the document is in force and that it really concerns your unit and the task.
Action
Translate the text as follows: report to the coordinate paper, reports and distance prescribed by the notice. Coordinates and limits must appear on the map or navigation system, not only remain in the memory.
Alternative
Plan B is to wait for instructions or use a different input if authorized and secure. On board preserves references Coast Guard e Hydrographic Institute of the Navy, an offline copy of important acts and sufficient autonomy. The commander must not collect links, but transform reliable information into limits, decision points and understandable alternatives.
