Tools

All the calculation tools for passage planning and navigation in one place.

Course conversion table

Convert the course from chart to compass — or the other way round. Current, leeway, variation and deviation step by step.

Choose

Chart → compass Compass → chart

Current triangle

Calculate the course correction for current — both chart to compass and compass to chart.

Choose

Chart → compass Compass → chart

Wind model

See how wind and leeway affect your course, and calculate the correct course to steer.

Bearings

Fix your position with cross bearings. Convert compass bearings to chart directions and find the fix on the chart.

Choose

Cross bearing fix Running fix

Deviation

Look up the compass deviation for any course steered. Linear interpolation straight from the deviation table — the same method used in the course conversion tables and My route.

Variation

Click on the map to find the variation – the magnetic variation for any point in Northern Europe.

Speed triangle

Calculate distance, speed and time interactively. Enter two known values – the third is calculated automatically.

Fuel triangle

Plan fuel consumption, flow and running time. Never run out of fuel again.
