The Importance of Passage Planning
Every voyage, no matter how short, should be planned in advance. A well-prepared passage plan ensures you have considered the weather, tides, hazards, timing, and contingencies before you...
Gather all the information you need: weather forecast, tidal predictions, chart analysis, port information, crew experience, and vessel capability. Identify potential hazards along the ro...
Plot the route on the chart. Mark waypoints, courses, distances, and expected times. Note tidal gates (times when the tide allows safe passage over a bar or through a narrows). Identify s...
Plot route with waypoints, courses, distances, and ETAs
Follow the plan, but remain flexible. Keep a navigational log at intervals matched to the risk: stable open water may justify hourly entries, while pilotage and nearby hazards require muc...
Continuously monitor your progress against the plan. Are you on track? Is the weather as forecast? Are the tides behaving as predicted? If conditions change — stronger wind, fog, equipmen...
Keeping a proper navigational record (log) is critical. It creates an audit trail of your decisions, helps you fix your position if electronics fail, and provides evidence if there is an...
