MCA Consults on New Safety of Navigation Regulations for 2027

The UK Maritime and Coastguard Agency has opened consultation on new Merchant Shipping (Safety of Navigation) Regulations planned for 2027, proposing to revoke and replace the current 2020 rules. The package is intended to bring UK law into line with newer SOLAS Chapter V requirements while also correcting gaps and clarifying how navigation obligations apply across domestic and international operations.

The consultation is open from 2 to 30 September 2026 and is relevant well beyond commercial cargo ships because the MCA notes that SOLAS Chapter V safety-of-navigation provisions apply to almost all ships operating internationally and domestically. For yacht owners, captains and managers, the proposals are therefore worth tracking even where an individual requirement may depend on size, use, tonnage or operating area.

New rules would replace the 2020 regulations

The MCA's preferred option is a complete replacement of the 2020 Regulations rather than another amendment layered onto the existing instrument. The new statutory instrument would implement recent changes to SOLAS Chapter V and consolidate other navigation-related corrections into a clearer legislative framework.

One driver is the international amendment covering lost freight containers, which entered into force through SOLAS on 1 January 2026 but was not automatically incorporated into the UK regulations. The replacement rules would implement updated danger-message and reporting requirements while also addressing several domestic issues that have developed since the 2020 framework was written.

Bridge visibility and equipment maintenance are in scope

The consultation proposes closing a gap between bridge-visibility standards applying to smaller domestic passenger ships and the SOLAS threshold applying from 55 metres length overall. It also proposes changing the relevant definition of length to length overall, reducing ambiguity where registered length and overall length can differ materially.

The draft framework also introduces or restates obligations around maintenance and performance of navigation equipment, placing responsibility on both master and owner in relevant cases. For large-yacht operations, that reinforces the principle that having approved equipment installed is not enough if maintenance arrangements cannot demonstrate that it remains capable of performing as intended.

AIS, autonomous ships and company liability also feature

The proposals include changes intended to consolidate AIS requirements and reinstate an exception for certain Class VI passenger vessels under 300GT, while retaining separate provisions for fishing vessels. The consultation also asks how responsibilities under safety-of-navigation law may apply to remote operators as the non-mandatory IMO MASS Code for autonomous ships begins to influence national legislation.

Another notable element is the extension of liability to the company in specified areas, including search-and-rescue plans, manning, danger messages and the master's discretion. That matters to yacht management structures because operational responsibility can sit across owners, managers and captains rather than being concentrated in one person.

Captains and managers have until 30 September to respond

The MCA expects the eventual regulations to come into force during 2027 after consultation responses have been considered, with an updated MGN 610 planned alongside them. The agency says the overall financial impact is expected to remain below the threshold requiring a full impact assessment, but the legal and operational details can still be significant for individual vessels.

Yacht operators should therefore follow the final text rather than assume the consultation draft will remain unchanged. The immediate opportunity is for owners, captains, managers, builders and specialist advisers with relevant experience to submit evidence before the 30 September deadline, particularly where the proposed rules interact with complex bridge systems or unusual operating profiles.
