A draft report into the sinking of a fishing trawler off the Cork coast appears to suggest the vessel may have been on auto-pilot when it became stranded at the entrance to its home port of Glandore.
The "Tit Bonhomme" foundered on Adams Island in the early hours of January 15 last year.
Five of her crew lost their lives and only one, Abdo Mohamad, 43, survived.
The bodies of Kevin Kershaw, 21, Wael Mohamad, 25, and Attia Shaban, 26, were recoveed within days of the sinking.
However, the search for skipper Michael Hayes, 52, and Egyptian crewman Saied Aly Eldin, 23, continued for 26 days until their remains were also recovered.
The accident report also suggests that the trawler was not fitted with an alarm to indicate to the crew that they were straying off course.
The official findings of the Marine Casualty Investigation Board are due to be formally published next week.
