MCA Issues Updated Guidance for Small-Vessel Navigation

The Maritime and Coastguard Agency (MCA) has published new guidance that is intended to support the technological development of digital navigation and its safe use by small commercial craft. 

The guidance sees an amendment being made to Marine Guidance Note (MGN) 319 (M+F) and 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. 

The MCA is also aiming to support equipment manufacturers by publishing clear specifications such as screen size and necessary features when using official charts. 

Ultimately, the guidance aims to ‘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’.

Navigation systems that comply with the new guidance will be known as ‘Small Vessel Electronic Chart Systems (SV-ECS).

Commenting on the new guidance, 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”.

The MCA has highlighted that the standards outlined in Marine Guidance Note (MGN) 319 (M+F) only apply to new hardware and software; existing Mini-ECDIS-compliant systems are still accepted when fitted to a vessel prior to 31st July 2026.
