The maintenance of the Solway Harvester has cost Manx taxpayers £57,000 since the scallop dredger sank off the east coast of the Island nearly eight years ago.
It's been revealed a local company is paid £150 a week to act as a caretaker.
It carries out a daily inspection, tends to mooring lines, ensures the vessel is water tight and adjusts moorings and stability in times of adverse weather.
The information was revealed by Chief Minister Tony Brown in a written reply to a House of Keys question, tabled by North Douglas MHK John Houghton.
The inquest into the deaths of the seven crewmen was adjourned last January, and authorities in the Island have said the vessel will remain in Douglas until the proceedings have concluded.
