UK Proposes New Legal Navigation Duties for Masters and Owners as 2027 SOLAS Rewrite Expands Liability
🔔 Subscribe to ShipUniverse Weekly →
The UK Maritime and Coastguard Agency has opened a four-week consultation on a major rewrite of its merchant-shipping navigation rules that would put several SOLAS Chapter V requirements more directly into domestic law and widen who can be held responsible when they are breached. The proposed Merchant Shipping (Safety of Navigation) Regulations 2027 would replace the 2020 regulations, apply to UK ships wherever they operate and generally to foreign ships while in UK waters, and are intended to enter into force during 2027. Among the most notable changes are a new statutory duty on masters to use the North Atlantic Ice Patrol when required, a new duty on both owners and masters to maintain adequate arrangements for the performance of navigation equipment, expanded company liability, and UK enforcement of the new international rules requiring lost freight containers to be reported. The consultation opened September 2 and closes September 30, 2026.
Operator Impact Snapshot
The proposal is mainly a SOLAS update, but several provisions change who carries direct legal responsibility when navigation procedures, equipment or reporting requirements fail.
MCA opened the four-week consultation on September 2.
One falls directly on the master and the other on both owner and master.
SAR plans, manning, danger messages and protection of the master's discretion.
The 2020 Safety of Navigation Regulations would be revoked and replaced.
New SOLAS reporting rules entered into force internationally in January 2026.
Navigation Duty & Liability Board
Not every SOLAS duty is new, but the proposed legislation changes several points of direct liability and closes gaps that previously sat in guidance or older regulations.
| Requirement | Responsible Party | Proposed Legal Exposure | Status | Operational Meaning | Control Worth Reviewing |
|---|---|---|---|---|---|
| North Atlantic Ice Patrol | Master | Fine on summary conviction or indictment. |
NEW UK DUTY SOLAS V/6.1 is being expressly incorporated. |
Ships navigating the iceberg region during ice season must make use of International Ice Patrol services. | Passage-plan procedures, ice-report monitoring, bridge checklists and records showing use of the service. |
| Navigation Equipment Maintenance | Owner + Master | Consultation narrative and offence comparison describe the new breach as fine-only. |
NEW UK DUTY SOLAS V/16. |
Adequate arrangements must exist to keep required navigation equipment performing properly. | PMS records, equipment manuals, defects, service intervals, spares and procedures for operating with unavailable equipment. |
| Lost Freight Container Reporting | Master + Company | Relevant regulation V/31 breaches can attract a fine and, for specified offences, up to two years' imprisonment on indictment. |
NEW UK ENFORCEMENT International rule already effective from January 2026. |
Losses must be reported to nearby ships, the nearest coastal State and flag State. Observed drifting containers also trigger reporting. | Emergency reporting template, company escalation chain, NAVAREA contacts and accurate position / cargo information. |
| Danger Message Content | Master / Responsible Person | Proposed fine-only offence for failure to provide the required information. | LIABILITY CHANGE | Regulation V/32 specifies the information that must accompany danger and lost-container messages. | Bridge reporting procedures, communications drills and current NAVAREA contact information. |
| Passenger Ship SAR Plan | Owner + Master + Company | Serious offences can carry a fine and/or up to two years' imprisonment on indictment. | COMPANY ADDED | International passenger ships must maintain a plan developed with appropriate search-and-rescue services. | Exercise records, company responsibilities and evidence the SAR plan is current. |
| Master's Safety Discretion | Owner · Charterer · Company · Other Responsible Person | Fine and/or up to two years' imprisonment on indictment. | EXPANDED LIABILITY | No commercial or operational party may prevent the master from making a decision considered necessary for safety or environmental protection. | Charter instructions, commercial pressure escalation, SMS wording and master's overriding authority. |
| Domestic Passenger Ships | Wider Fleet Scope | Applicable Chapter V offences become enforceable under the replacement regulations. | SCOPE CHANGE | Most seagoing domestic passenger ships would no longer sit under a static 2020 version of SOLAS Chapter V. | Gap analysis against the current Chapter V text rather than older domestic references. |
| Small Passenger Ship Bridge Visibility | Owner + Master | Summary-conviction fine for non-compliance with applicable bridge-visibility requirements. | 45-55 m GAP CLOSED | Existing legislation would change from less than 45 metres registered length to under 55 metres length overall. | Measure LOA, assess sightlines and confirm the vessel falls under the correct visibility standard. |
| Pilot Transfer Arrangements | Owner + Master + Responsible Persons | Fine-only offence under the proposed framework. | JAN. 1, 2028 | New mandatory performance standards cover design, installation, securing, inspection, maintenance and familiarisation. | Pilot ladders, securing arrangements, lighting, records, replacement dates and crew training. |
| Maritime Autonomous Ships | Still Being Defined | MCA is consulting on which responsibilities could properly shift to remote operators. | REGULATORY WATCH | Possible remote-operator duties include routeing, reporting, Ice Patrol use, weather reporting and danger messages. | Remote Operations Centre roles, master's authority, reporting handoffs and SMS responsibility matrices. |
