This 2021 edition of ECDIS Passage Planning and Watchkeeping provides best practice techniques and guidance on the use of ECDIS. It includes clear explanations of the configuration of ECDIS settings and the four stages of route planning, using the APEM method set out in IMO Resolution A.893(21). The text is divided into user-friendly sections, with attention drawn to operator guidance and safety critical information.

This publication equips navigators with a thorough knowledge of ECDIS, contributing towards safer ship operation/navigation and a more effective bridge team. It encourages operators to practise the use of every function and technique available on ECDIS, such as setting correct safety depths and safety contours, as well as understanding topics such as scale minimum (SCAMIN) and alarm management.

Updated ECDIS screenshots and illustrations such as the APEM (appraisal, planning, execution and monitoring) flowchart aid readers’ understanding of best practice techniques.
