The Jeanie Johnston has disappeared from her moorings on the north Dublin quays.
But fans of the replica famine ship need not worry - she is only getting a quick inspection and a lick of paint before returning to the Liffey.
The popular seagoing museum was towed away from Custom House Quay on Tuesday night to a dry dock where she will be inspected and have her hull painted.
This will ensure she provides many more years of enjoyment for sailing fans and history buffs.
The wooden vessel is an authentic replica, built in Tralee, of the Jeanie Johnston which was built in Quebec in 1847.
The original vessel made 16 emigrant voyages to North America between 1847 and 1855 and carried more than 2,500 people with no loss of life.
The replica has sailed to North America and various ports in Europe.
"It's not only tourists who love it, we find a growing number of Dubliners and Irish people coming to it because of its history and uniqueness," said John O'Neill, general manager of the tall ship and famine museum.
"While she's in dry dock we will have her fully inspected and surveyed.
"This is important to do every few years to ensure that she is kept in good condition.
"Once she is brought into the dry dock the water will be pumped out so we can see all of the hull, and then she will be inspected plank by plank.
"This is the right time of year to carry out this work because the tourism season is over and it's a quieter period, so it affects fewer people."
