The Roman wreck, Asterix, is being preserved in Portsmouth
A 1,700 year-old ship wreck could be returned to Guernsey if funding can be found, after undergoing preservation work since it was raised in 1985.
The Asterix was found by local diver Richard Keen in St Peter Port harbour in 1982, where it had lay since 280.
The timbers were taken to the Mary Rose Trust in Portsmouth for immersion in wax and freeze drying.
Guernsey Museum Service said money is needed to pay for somewhere to store and display the ship.
The Asterix was destroyed by fire and sunk in the 3rd Century where the entrance to St Peter Port harbour was later established.
The museum service has said it hopes to bring the wreck, measuring 18m (60ft), back to the island for a permanent display.
