Appraisal

– Weather

– Tides

– The vessel

– The crew

– Navigational dangers

– Contingency plans (bolt holes, ports of refuge)

Planning

On the basis of the fullest possible appraisal, a detailed voyage or passage plan should be prepared which should cover the entire voyage or passage from berth to berth.

– Distance

– ETD (Departure)

– ETA (Arrival)

– Tidal gates and hazards

– Alternative ports and shelters on route

– Waypoints

Execution

Execute, review, change if required

Monitoring

Monitor the passage plan by all available resources. The progress of the vessel in accordance with the plan should be closely and  continuously monitored to ensure early indication of a need for variation.
