New MCA guidance modernises navigating for small commercial vessels, ensuring safe transition to digital systems
The Maritime and Coastguard Agency (MCA) has unveiled updated guidance aimed at modernising navigation practices for smaller commercial vessels, ensuring safety and compliance as the maritime industry embraces digital technology.
The amendment to Marine Guidance Note (MGN) 319 (M+F), published today, introduces new standards for electronic chart systems used by commercial vessels up to 24 metres in length. These updates provide a roadmap for operators transitioning from traditional paper charts to digital navigation tools while setting clear requirements for manufacturers of navigation hardware and software.
Enhancing Safety with Digital Navigation
The revised guidance establishes the term Small Vessel Electronic Chart System (SV-ECS) for compliant systems and outlines specifications such as screen size and functionality. It also emphasises the importance of backup arrangements to ensure navigational safety in case of system failures.
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.”
Collaborative Approach
The update to MGN 319 (M+F) has been developed in consultation with industry stakeholders and electronic chart system manufacturers. The guidance not only clarifies compliance for current operators but also ensures that future navigation tools meet high standards for safety and usability.
Key Points of the Guidance
- Scope: Applies to small commercial vessels (up to 24 metres in length) operating under the UK flag in UK waters. This includes workboats, pilot boats, small motor vessels, and vessels used for sport or pleasure.
- Transition Timeline: Existing Mini-ECDIS systems will remain compliant until 31 July 2026, allowing a phased transition to SV-ECS standards.
- Manufacturer Standards: Specific guidelines for hardware and software design to support safe and efficient navigation.
Looking Forward
This amendment is expected to facilitate a smoother transition for seafarers and navigation technology providers as they adopt digital solutions tailored to small commercial vessels. The MCA’s proactive approach reflects the agency’s commitment to safety, innovation, and industry collaboration.
MGN 319 (M+F) has been developed in consultation with industry and manufacturers of electronic chart systems.
