The first two stages are preparation, while stages three and four are carried out during the passage to ensure the safe navigation of the vessel. To ensure a safe passage, the procedure must be supported by good information and data.

Documents/publications used for passage planning, supplement the courses on the chart(s) and are referenced in the plan for use in the execution and monitoring. The plan is prepared from berth to berth in accordance with the STCW Code. It should contain:

• identification of hazards, such as rocks, wrecks, shallow waters, tides, and weather;
• courses the vessel must follow; and,
• contingency plans to be followed in the event that the vessel meets a hazard.

A good passage plan:

• establishes priorities and the clear delegation of responsibilities, at predetermined times and locations, to assist the master, watchkeepers, and pilots (if used);
• allows the continuous monitoring of the plan; and,
• is designed to reduce complacency and over-reliance on electronic aids to navigation;
  
  

Regardless of who prepares the plan, it is good practice to have another navigator verify that it is safe and comprehensive. The plan must then be approved and signed off by the master.
