Argos Georgia sank after a shell door opened in heavy seas, MAIB finds
Thirteen of 27 crew died off the Falklands; the hatch's manual lock had likely not been applied
The loss of the longliner Argos Georgia off the Falkland Islands in July 2024, in which 13 of the 27 people aboard died, began when the starboard line-hauling hatch opened in heavy seas and the crew could not close it again. That is the central finding of the UK Marine Accident Investigation Branch's final report into the sinking.
The 2018-built, St Helena-registered vessel had left Stanley for fishing grounds near South Georgia. On 22 July 2024, about 190 nautical miles east of the Falklands capital, the hatch in the line-hauling room opened while she was under way. Water poured in and spread to other compartments, and the vessel took on a growing starboard list that the crew could not control. She foundered; 14 people survived. Nine bodies were recovered and four crew remain missing, presumed dead.
The investigators found that the hatch's manual securing mechanism had likely not been applied. They also identified a previously unrecognised weakness in its drive mechanism. An interim safety bulletin issued in September 2025 had already set out that finite element analysis showed "an unacceptable level of stress and potential failure of the shell door drive shaft, coupling and key" in normal operation, and that a failed mechanism left nothing to stop the door lowering to the open position.
The flooding was made worse by weathertight doors left open, electrical systems vulnerable to water and manual controls that could not be reached. The report describes the crew's response as unstructured and finds that delays in declaring distress and in abandoning ship cut the time available for rescue. Poor control of the evacuation, extreme weather and damage to the liferafts increased the crew's exposure to cold water.
The MAIB also found shortcomings in shoreside management at the operator, Argos Froyanes, including inadequate systems for controlling safety-critical risks and for assessing, escalating and responding to flooding, abandonment and distress in severe weather and remote waters.
"This was a tragic accident resulting in the loss of 13 lives," said Rob Loder, Chief Inspector of Marine Accidents. "Fishing in the remotest and most hostile parts of our oceans requires strict adherence to the maintenance of a vessel's watertight integrity." When a problem arises, he said, "a quick, clear and efficient emergency plan should be executed."
The final report recommends that the Maritime and Coastguard Agency amend its code for fishing vessels of 24 metres and longer to require shell doors with automatic locking arrangements that secure them closed. Argos Froyanes is asked to implement a documented safety management system across its fishing fleet, and the Falkland Islands government to improve its search and rescue communications so it can reach vessels in distress directly.
The MAIB carried out the investigation on behalf of the St Helena Government under the Category 2 Red Ensign Group memorandum of understanding, and published a safety flyer for the fishing industry alongside the report.
