Everyone has a favourite. Our goal with this chart is to outline the key distinctions among the 14 most popular ships for UK passengers in an easily digestible way. So how do we define "popular"? – Put simply it's how many visits each ship gets on the Cruise Critic website since the start of the year.

If you want more information about a particular ship or to see photos, just click on the vessel name for a comprehensive expert review and hundreds of reader-submitted critiques.

1. Iona

P&O Cruises' latest ship has not welcomed a single passenger onboard (it was due to launch in summer 2020) due to the Coronavirus pandemic, yet it is your most popular ship by a wide margin. The 5,200-passenger vessel is the line's first liquefied natural gas- (LNG) powered and the line's biggest.

The ship's main feature is the Atrium, which will have glass panels, letting in loads of natural light. There will also be a grand staircase, a gallery and overhead walkways.

A giant dome called SkyDome, will feature aerial performances, projections onto the roof and immersive shows.

The ship will include 30 places to eat including seven speciality restaurants and celebrity wine and food partnerships -- Michelin-starred chef Marco Pierre White, master patissier Eric Lanlard and Alex James, of Blur fame, and now better known for cheeses -- are just three big names.

Iona will also have 12 bars, 13 entertainment venues, three pop-up entertainment spaces/venue, four swimming pools (three outside and one inside) and 16 whirlpools.

Deployment: When Iona finally launches, it will spend the summer in the Norwegian fjords and the winter in the Canaries.

Marella Explorer started out at Celebrity Galaxy in 1996 and later became TUI Cruises' Mein Schiff 1 before undergoing the transformation that turned it into Marella Explorer. Despite its age (23 years old), this ship is extremely popular with Brits -- and the first of four Marella ships which dominate this chart.

It has 10 dining venues, including favourites Kora La and Surf & Turf, as well as sushi, pizza and tapas restaurants, and a bar-nightclub-casino called Indigo as well as 13 brand-new, hi-tech production shows. One of Marella's key selling points is that it is largely all-inclusive with drinks and tips included in the fare.
