Update to stay ahead of developing technology and maritime
practices.
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.
