Marella Cruises currently sails five ships, and they are closer in size than many people expect. Ranked by gross tonnage, Marella Voyager is the biggest (about 77,300 tonnes, roughly 1,900 guests), followed closely by Marella Explorer, then Marella Explorer 2, with the sister ships Marella Discovery and Marella Discovery 2 the smallest at around 69,000 to 69,500 tonnes. All five were built between 1995 and 1997 for Royal Caribbean or Celebrity Cruises and have been refitted for British holidaymakers. As of October 2026 no ship has left the fleet and no new ship has joined. Marella Explorer 2 is adults-only, and Marella Discovery 2 is also adults-only for winter 2026/27 and is due to become permanently adults-only from winter 2027.

Has the Marella fleet changed?
Not in terms of ships. The fleet has stayed at five since Marella Voyager (formerly Celebrity Mercury and TUI Cruises’ Mein Schiff Herz) arrived in June 2023. There have been rumours about other ex-Celebrity or ex-Mein Schiff ships moving across, but nothing of the sort had been announced at the time of writing.
The bigger news was about new ships. In March 2025 TUI agreed a deal with Fincantieri for two new, smaller ships designed for Marella, due in 2030 and 2032. In September 2025 TUI changed course and passed those shipyard slots to TUI Cruises, its German joint venture with Royal Caribbean Group, which will build larger ships instead. For now, then, Marella is sticking with its existing, heavily refurbished fleet. The summer 2028 programme, announced in October 2026, still uses the same five ships.
The changes that do matter for passengers are about who can sail on each ship:
- Marella Explorer 2 remains the line’s dedicated adults-only ship.
- Marella Discovery sailed adults-only for summer 2026 from Limassol in Cyprus. TUI now lists it as family-friendly again, sailing from La Romana in the Dominican Republic for winter 2026/27.
- Marella Discovery 2 is adults-only for winter 2026/27 in the Canary Islands. Marella says it will become permanently adults-only from winter 2027, when four former children’s areas become a speakeasy, an escape room, a karaoke room and an arts and crafts space.
Marella ships by size
Here are the five ships ranked from largest to smallest. Tonnage and capacity figures vary slightly between sources, so treat them as close approximations.
| Rank | Ship | Gross tonnage | Guests (approx.) | Length |
|---|---|---|---|---|
| 1 | Marella Voyager | 77,302 | 1,910 | 264m |
| 2 | Marella Explorer | approx. 77,000 | 1,920 | 264m |
| 3 | Marella Explorer 2 | 71,545 | 1,810 | 248m |
| 4 | Marella Discovery 2 | 69,472 | 1,830 | 264m |
| 5 | Marella Discovery | 69,130 | 1,830 | 264m |
To put that in context, the largest new ships from other lines sailing from Britain carry well over 5,000 guests. Every Marella ship is mid-sized by today’s standards. That means fewer queues, easier walking distances and less time getting on and off in port, but fewer big attractions such as water parks or multi-deck theatres.

Marella ships by age
All of the ships are around 30 years old, so the main difference between them is how recently they were refitted. Here they are ranked from newest build to oldest.
| Ship | Built | Original name | Joined Marella |
|---|---|---|---|
| Marella Voyager | 1997 | Mercury (Celebrity) | 2023 |
| Marella Explorer | 1996 | Galaxy (Celebrity), later Mein Schiff 1 | 2018 |
| Marella Discovery | 1996 | Splendour of the Seas (Royal Caribbean) | 2016 |
| Marella Explorer 2 | 1995 | Century (Celebrity) | 2019 |
| Marella Discovery 2 | 1995 | Legend of the Seas (Royal Caribbean) | 2017 |
Marella Voyager is the newest addition to the fleet and had the most recent full transformation, at Navantia in Cádiz, before its first sailing in 2023. The others have had regular dry docks. Discovery 2’s last one, for example, was in autumn 2024. Older hardware can mean smaller standard cabins and fewer balconies than on a modern ship, so it is worth checking the deck plan before you book.
Restaurants and facilities on each ship
Marella’s fares are all-inclusive. Main restaurants, the buffet, a good range of drinks and tips are covered. Speciality restaurants such as Kora La (pan-Asian) and the Surf & Turf Steakhouse cost extra, as do spa treatments, Wi-Fi and excursions. The counts below are taken from TUI’s own ship pages and include casual eateries as well as sit-down restaurants.
| Ship | Restaurants | Bars | Stand-out features |
|---|---|---|---|
| Marella Voyager | 18 | 10 | The Kitchens food hall, Abuela’s Mexican, Silver Fork, speakeasy bar, cinema, kids’ and teens’ clubs |

Kora La, the Sushi Bar and the Surf & Turf Steakhouse cost extra. Discovery 2’s adults-only conversion will replace its children’s areas with new venues for grown-ups.

Where each ship sails matters as much as the ship itself. For winter 2026/27, Voyager and Explorer 2 are based in Barbados, Discovery in La Romana, and Explorer and Discovery 2 in Tenerife and Gran Canaria. In summer the fleet moves to the Mediterranean. For summer 2028, Explorer will be in Corfu, Explorer 2 in Malaga, Discovery and Voyager in Palma, and Discovery 2 in Dubrovnik. Seven-night fly-cruises including flights often cost somewhere around ÂŁ900 to ÂŁ2,000 per person, depending on the season, the cabin and how early you book. Prices change often, so check with TUI or your travel agent.
