A gas explosion caused a Co Down fishing boat to sink with the loss of three generations of the same family, it has been confirmed.
A report by the Marine Accident Investigation Board into the sinking of the Tullamurray Lassfrom Killkeel, found that the most likely source of the gas was a leak in the vessel's heating system.
An eight-year-old boy, his 32-year-old father and 54-year-old grandfather, all called Michael Greene, were lost when the fishing boat went down a few miles off shore in February 2002.
After weeks of searching by both British and Irish naval ships and police divers all three bodies were recovered from the sea.
The 10-metre prawn boat had been due to be taken out of service a month after the sinking under the government's fishing boat decommissioning scheme.
The accident report recommended that all owners and skippers of fishing vessels follow the Maritime and Coastguard Agency's advice on the safe use of space heaters which use LPG.
