The planning for dogs, wrecks and diving points can be summarised in three words: source, action, alternative. The source clarifies professional and recreational activities; the action modifies the route; the alternative avoids staying without choice.
Source
See the official act and avoid focusing only on the boa without considering current, support cables and media support. Check that the document is in force and that it really concerns your unit and the task.
Action
Translate the text like this: reduce the gait, increase the viewer and comply with current distances and prescriptions. Coordinates and limits must appear on the map or navigation system, not only remain in the memory.
Alternative
Plan B consists in extending the route instead of crossing an area with unsure sub position. 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.
