MS Iona

MS Iona is an Excellence-class cruise ship in service for P&O Cruises, a subsidiary of Carnival Corporation & plc. Built by German shipbuilder Meyer Werft in Papenburg, she was delivered in October 2020 at a cost of £730 million. At 184,089 GT, Iona became the largest cruise ship commissioned for P&O and the British market upon delivery until sister ship Arvia was delivered in 2022. Iona was floated out on 18 February 2020 and delivered eight months later on 9 October amid the COVID-19 pandemic, which delayed her debut by more than a year until 7 August 2021, when she sailed her maiden voyage from Southampton.

Key reported specifications for MS Iona include a passenger capacity in the vicinity of 5,206, an overall length of approximately 345 metres.

Onboard programming on a vessel of MS Iona's profile typically includes multiple dining venues, a central showroom, pool deck areas, a spa and fitness facility, themed bars, and on family-oriented brands children's and teen spaces.
