Thomson Cruises’ new ship will be called Thomson Discovery and it will homeport in Palma when it launches in June next year.
The ship has been acquired from Royal Caribbean International and until now it has been known as Splendour of the Seas.
Before setting sail under the Thomson name, the ship will undergo a re-brand and refurbishment.
The vessel, which will be the largest in the Thomson Cruises fleet, will offer 40% balconies which managing director Helen Carron believes will prove a popular unique selling point.
Tui UK and Ireland boss David Burling applauded the efforts of the new merger with Tui AG in helping to secure a new vessel for the companies UK cruise brand.
He said the merger meant the ship deal was done quick and efficiently and was an example of the good work being achieved through the merger.
He said: “We have strength in our service, food and entertainment already and now we can combine it with having genuinely good hardware.
“It would have been incredibly difficult for us to deliver what we have done with Splendour of the Seas without the help of Tui Cruises (the line’s German sister brand).
“This is one really good example of how the new bigger Tui group is helping us and we’re seeing benefits at Tui UK and Ireland and it’s helping us deliver things very quickly.
“The merger is helping us in the UK and its happening quickly.”
Speaking at the launch of the 2016 summer product, Caron said the ship will keep the climbing wall which was put in place by Royal Caribbean, and said it would offer an outdoor cinema.
Caron said the new ship was “just the start” of the line’s new strategic plans to grow and develop in the UK market.
She added: “The introduction of the ship is part of our on-going modernisation and transformation strategy, which has included recent investment in our other ships.
“The newest addition is larger than the others in our fleet, however, it still fits with our strategy of operating smaller ships with must-do itineraries.”
Thomson Majesty will also sail from Palma in 2016, while Thomson Spirit will homeport in Malaga for the summer season and Thomson Dream will cruise from Corfu.
Thomson Celebration will continue to sail from Dubrovnik next year, after this year’s itinerary became the most popular for the line, Carron said.
