Technical Specifications

Accommodation Configuration

Iona offers diverse cabin options across 11 passenger decks, catering to various preferences and budgets. The 2,614 cabins include 819 interior rooms, 121 suites, 32 single-occupancy studios, and 55 wheelchair-accessible accommodations. The largest suites are the two-room Sky Suites, spanning 400 square feet with an additional 110 square-foot terrace or step-out balcony.

Power and Environmental Features

The vessel employs Wärtsilä LNG engines paired with three cryogenic steel tanks storing approximately 3,200 cubic metres of liquefied natural gas. This propulsion system delivers 74 megawatts through two azimuthing thrusters, achieving a service speed of 17 knots. The LNG technology entirely eliminates sulphur dioxide emissions and removes soot particles from the exhaust—a significant environmental advancement compared to traditional heavy fuel oil propulsion systems.

What is the P&O Iona itinerary?

Iona’s operational schedule follows a seasonal pattern designed to showcase diverse destinations throughout the year. Understanding her itinerary structure helps prospective passengers identify the optimal time to sail based on preferred cruising regions and desired experiences.

Summer Season Operations

During summer months, Iona operates primarily from Southampton on seven-day Norwegian fjord voyages. These itineraries typically include stops at iconic destinations such as Bergen, Geirangerfjord, Stavanger, and Flåm, offering passengers opportunities to experience dramatic landscapes, historic port towns, and natural wonders including cascading waterfalls and steep fjord walls. One example departure runs from April 18 to April 25, 2026, following the standard Norwegian Fjords route.

Winter Season Operations

The winter months see Iona transition to warmer cruising grounds, with deployments in the Canary Islands and Northern Europe. These voyages provide an alternative for passengers seeking milder temperatures and Mediterranean-style experiences during the British winter period. The ship maintains comfortable onboard environments while visiting destinations in the Atlantic islands and coastal European regions.

Maiden Voyage History

Iona’s inaugural season faced unprecedented challenges due to the COVID-19 pandemic. Originally scheduled to begin with Norwegian fjord cruises from Southampton, the maiden voyage was postponed multiple times as travel restrictions evolved. On 7 August 2021, Iona finally launched along the Inner Hebrides, operating week-long voyages through September. All inaugural season voyages were restricted to UK residents only, reflecting government guidance at the time.

2026 and 2027 Outlook

While general Norwegian fjord operations continue for 2026 and beyond, detailed itinerary specifications for these years remain limited in available search results. P&O Cruises announces specific voyages progressively, and passengers interested in particular departure dates should monitor the official P&O website for the most current schedule information. The ship underwent refurbishment in 2025, ensuring updated amenities and refreshed interiors for future seasons.

The retractable design allows passengers to enjoy swimming regardless of weather conditions while maintaining an open, airy atmosphere. The three-tier Grand Atrium with panoramic views similarly receives positive attention for creating a grand social space at the ship’s heart.

Culinary and Entertainment Offerings

The 30-plus dining and drinking venues aboard Iona represent a significant expansion compared to earlier P&O vessels. The onboard gin distillery has emerged as a particularly noted attraction, offering passengers interactive experiences and exclusive gin varieties. Musical direction from Gary Barlow brings contemporary British entertainment credentials, appealing to passengers seeking familiar cultural touchstones during their voyage.
