Electronic Navigation Systems

Guidance for safe use on leisure vessels v.2

2025 edition.

This booklet from the Royal Institute of Navigation provides guidance on the safe use of electronic navigation and associated systems on leisure vessels.

Navigating a leisure vessel has always required the skipper/navigator to use all available information and that has never been more important than now, with the availability of ever-increasing sources of information. Good navigational safety is still dependent on the continuous assessment by the skipper/ navigator of all the navigation-related information available on the vessel – and not just over-concentrating on some, however beguiling they may be.

The new version incorporates updates in the light of developments in GNSS, electronic charts and their display systems, as well as feedback from readers, including a new sub-section on Astronavigation, within Chapter 5.

Edited by Jane Russell, illustrated by William Thomson.
