Charts & Publications

• Select chart coverage and scale for each passage stage, then establish the chart's edition, update status, units, datums and important cautions before using it.
• Use the correct symbol reference and chart legend to interpret paper-chart symbols, depth soundings, drying heights and colour tints without relying on a memorised colour shortcut.
• Establish the update status of paper charts, electronic chart data and supporting publications, then record or resolve every relevant gap before departure.

A self-guided revision companion that explains essential concepts, then helps you practise and test them. It supports—but does not replace—recognised instruction, practical training, assessment or certification. Access is a one-time payment, not a subscription.
