How to plan a passage

1Set your departure time, boat speed and draught in the Route details panel.
2Click the chart to drop waypoints along your route — the line joins them in order.
3Each leg gets a course to steer (°T and °M), SOG and ETA using the nearest tidal diamond.
4Tap a leg to see the full workings — hourly stream vectors and the triangle, drawn on the chart.
5Set a minimum height of tide to check tidal gates, then print the plan sheet.
