The vessel, which was due to depart on its inaugural sailing in January 2024, will now sail from Southampton to Lisbon on 3 May 2024.
A spokesperson for the line said: "Due in part to unforeseen events that have occurred in recent years, the shipbuilding industry, like other industries, has faced numerous challenges including energy shortages and global supply chain constraints.
"We have automatically transferred guests booked or waitlisted on the maiden voyage to the new seven-night maiden voyage."
