The world's largest cruise liner, Queen Mary 2 - hit by tragedy even before its launch - is having problems once again.
The QM2 returned to Southampton three and half hours late
She arrived back at her home port 210 minutes late after bow doors covering propellers failed to shut in Portugal.
The £650m QM2 set sail from Southampton on its maiden voyage in January after being officially launched by the Queen in a blaze of fireworks and music.
The launch came after 12 people died when a gangway collapsed while the ship was in dry dock at St Nazaire, France.
Most of the victims, including at least two children, were dockyard workers' relatives visiting the ship for the first time.
During sea trials, two women aged in their 60s had to be removed from the QM2 by the coastguard after breaking their legs.
One was injured boarding the ship and the other while dancing.
The 150,000-ton vessel finally returned to Southampton from Lisbon, on the last leg of her return trip to Florida, at about 1030 BST on Monday.
Cunard spokesman Eric Flounders said a small number of passengers might miss connecting flights but the company had already offered them compensation.
"This is just one of those things; it wasn't a serious mechanical failure but something that had to be dealt with before it went to sea," he added.
The vessel has 1,310 cabins on board
The QM2 is due to depart for Guernsey in the Channel Islands later on Easter Monday, marking the beginning of a new season of voyages.
Measuring 1,132ft long (345 metres), the vessel carries 2,620 passengers and 1,253 crew.
She has 1,310 cabins, including four royal suites and six penthouses, 2,000 bathrooms and 3,000 telephones.
On board are five swimming pools, an art gallery and a planetarium. Twenty one lifts will ferry passengers between her 17 decks.
She will eventually take over the Southampton to New York route from the QE2.
