New guidance has been published by the Maritime and Coastguard Agency (MCA) today (Monday 13 January 2025) to support the technological development of digital navigation and its safe use by smaller commercial craft.
An amendment to Marine Guidance Note (MGN) 319 (M+F) sets out updates for accepted standards and compliance for electronic chart systems used as a means of navigation by operators of commercial vessels up to 24 metres in length.
To also support equipment manufacturers to develop safe and effective hardware and software, it is being published alongside clear specifications such as screen size and necessary features when using official charts.
The guidance will assist both seafarers and digital navigation companies to secure viable, compliant alternatives to paper charts and facilitate the transition to electronic navigation. It also clarifies the required provision of suitable back-up arrangements.
Compliant systems will be termed Small Vessel Electronic Chart System (SV-ECS).
Mike Bunton, MCA Head of Navigation, said
Clear and reliable navigation systems, when used by a well-trained navigator, can significantly improve safe navigation at sea. The MCA is updating its guidance to stay ahead as technology develops and maritime practices change.
With safety in mind, this Marine Guidance Note update supports operators to understand their obligations clearly. It also guides manufacturers of electronic charting hardware and software so their products provide the tools needed for safe and efficient navigation.
MGN 319 (M+F) has been developed in consultation with industry and manufacturers of electronic chart systems.

Background
MGN 319 (M+F) applies to small vessels in commercial use (code boats) up to 24 metres load line length operating under the UK flag and in UK waters, including small motor vessels, small sailing vessels, small workboats and pilot boats, and small commercial vessels used for sport/pleasure.
The standards apply only to new hardware and software; existing Mini-ECDIS-compliant systems are still accepted where fitted to a vessel prior to 31 July 2026.
