The UK has become one of the leaders internationally in upholding the safe operation of smaller Remotely Operated Unmanned Vessels (ROUVs) with new guidance published by the Maritime and Coastguard Agency (MCA).
Marine Guidance Notice (MGN) 705 (M), which comes into force today (31 December 2024), sets out a pathway for operation of the rapidly growing number of hi-tech ROUVs between 2.5 and 4.5 metres in length.
It puts the UK among the first in the world to formally set out the scope of regulation and operators’ obligations in this emerging category, as well as the MCA’s commitments to well-founded oversight that keeps people safe.
Publication is the first step since extensive consultation began in 2022 with a range of maritime industries.
The core of MGN 705 (M) is a two-year general exemption for eligible ROUVs. It runs alongside research commitments by the MCA to ensure future updates are underpinned by firm evidence and clear criteria.
Key obligations are set out for owners and operators, such as for eligible ROUVs to be under constant supervision by a human able to take control at any time.
A safety assurance assessment must be declared before operation, and speed will be limited to 6 knots or planing speed, whichever is lower. Other safety requirements cover vessel visibility, anti-fouling, and remote camera capability.
The MCA has committed to reviewing MGN 705 (M) by 31 December 2027 to ensure the conditions remain supportive for ROUV technology to progress safely.
MCA Code Vessel Lead Rob Taylor said
The welfare of people at sea is our priority, whatever the vessel. Through MGN 705 (M) we will continue to support the development and safety of ROUVs and take swift regulatory action where the evidence leads.
This is not the end of the process. We will continue to listen and respond to new technology and feedback. Our aim is to maintain regulations that are proportionate, consistent, evidence-led and, most importantly, keep people safe.

Background
General Exemption enables eligible vessels to operate without certification issued by the MCA or its delegates.
Remotely Operated Unmanned Vessel (ROUV) means a vessel with no persons on board that is operated from a location remote to the vessel.
MGN 705 (M) follows MGN 702 (M) which gave a general exemption to ROUVs less than 2.5 metres in length. ROUVs above 4.5 metres are certified using the Workboat Code Edition 3 and by submission of appropriate equivalence requests.
