An investigation led by the Marine Accident Investigation Branch (MAIB) has found that the sinking of the Isle of Man-flagged cargo vessel Verity after its collision with Polesie in the German Bight on 24 October 2023 was caused by serious navigation and watchkeeping failures.
The investigation found that both vessels’ watchkeepers accepted dangerously close passing distances. When collision-avoidance actions were taken, they were neither timely, positive, nor clearly apparent to the other vessel. Proper use of a VHF radio could have helped avert the accident.
German Bight VTS intervention in the final stages was delayed and ineffective. Verity sank rapidly, leaving the crew no time to don lifejackets or immersion suits.
The report highlighted key safety issues. IRPCS requires that collision-avoidance actions be timely, positive, and clearly visible.

Maintaining an effective lookout is essential, particularly in or near traffic separation schemes. VTS operators provide a critical safety service but must ensure timely and appropriate interventions.
Recommendations were made to shipping companies to reinforce compliance with IRPCS and safe watchkeeping standards.
The German Directorate General for Waterways and Shipping was advised to review duplex VHF usage and improve guidance for vessel communication and close-range interactions.
The Isle of Man Ship Registry was encouraged to propose voyage data recorder carriage extensions to the International Maritime Organization (IMO).
Andrew Moll OBE, Chief Inspector of Marine Accidents, said: “The tragic loss of Verity and five crew was entirely preventable. Vessels must act early and visibly to maintain safe passing distances. VTS interventions must be timely, and VHF radio can help clarify intentions, if used correctly.”
