The timbers have been undergoing restoration in the UK since 1999
The States cannot afford to bring the wreck of the Asterix back to Guernsey and put it on display, the Culture and Leisure minister has said.
The Gallo-Roman shipwreck was found in local waters in 1982 and since 1999 has been undergoing restoration in the UK.
Deputy Mike O'Hara said his department had spent a lot on the restoration, but it cost too much to bring it home.
He said: "We'd like to get the ship back and put it on display, but the money is not there at the moment."
Deputy O'Hara said: "Perhaps the sensible thing is to look for private investment or even someone in the private industry could help and give us a building or somewhere we can put it into, but at the end of the day at this present time the States would struggle to do something with it."
