Cruise Ships Size: P&O Cruises' 7-Ship Fleet Ranked by Tonnage

P&O Cruises Fleet Ranked by Gross Tonnage: Your Complete Size Guide

P&O Cruises, Britain's historic cruise operator tracing roots to the 1800s, maintains a seven-ship fleet offering remarkable diversity in cruise ships size. From the cutting-edge Arvia at 185,581 gross tons to the intimate Aurora at 69,154 gross tons, the line provides options for every traveler preference. Understanding how these vessels compare helps you select the perfect ship for your British-focused cruise experience, whether you prioritize modern amenities, classic elegance, or cozy authenticity.

P&O Cruises Fleet Overview: Seven Ships Serving British Travelers

The P&O Cruises fleet represents a unique positioning in the global cruise industry. Unlike mega-ship operators like Royal Caribbean or Carnival Corporation, P&O has deliberately maintained a smaller, curated collection of vessels optimized for British tastes and European itineraries.

This strategic approach allows the line to offer personalized service and British-centric programming unavailable on larger fleets. Each ship reflects the company's heritage and commitment to UK passengers seeking sophisticated, culturally-aligned cruising experiences. The fleet spans three distinct eras of cruise ship design, from ultra-modern LNG-powered vessels to contemporary favorites to classic ocean liners, giving travelers genuine choices based on ship personality rather than size alone.

The Largest Ships: Arvia and Iona Lead the Fleet

Arvia and Iona dominate P&O Cruises' size rankings as sister ships within the Excel class. Launched in 2022 and 2021 respectively, these mega-ships represent the line's modern flagship vessels designed specifically for the British market.

Arvia, at 185,581 gross tons, technically holds the title of P&O's largest ship. The vessel accommodates 5,200 passengers across 2,600+ cabins distributed over 16 decks. Amenities include four swimming pools (featuring an infinity pool), more than 30 food and beverage venues, and LNG-powered propulsion technology that reduces environmental impact. The ship operates primarily Caribbean and Mediterranean itineraries.

Iona, marginally smaller at 184,700 gross tons, offers virtually identical onboard experiences. With matching passenger capacity, cabin count, and crew complement, the distinction between these sisters remains imperceptible to most cruisers. Iona distinguishes itself through European-focused sailing and an impressive three-deck atrium with panoramic ocean views, plus 18 hot tubs and 15+ restaurants.

Both vessels represent P&O's commitment to contemporary cruising while maintaining distinctly British character and service standards. However, they remain modest compared to Icon-class rivals operated by competitors.

Mid-Size Vessels and Flagship Britannia: The Heart of P&O

Britannia, P&O Cruises' official flagship despite newer competition, commands respect at 143,000 gross tons. Christened by Queen Elizabeth II, this 2015-launched vessel carries 3,647 passengers and features one of the fleet's largest outdoor promenades. The ship boasts British-style breakfasts, UK-sourced spirits, a dozen restaurants, six bars and lounges, and distinctive cultural programming that attracts tradition-minded cruisers.

Ventura and Azura occupy the comfortable middle tier of P&O's cruise ships size range. Ventura (116,017 GT, 3,078 passengers, launched 2008) emphasizes family-friendly amenities including specialized kids' clubs and diverse dining venues like The Glass House wine bar and Michelin-starred Sindhu restaurant serving Indian cuisine.

Azura (115,055 GT, 3,066 passengers, launched 2010) closely mirrors Ventura's specifications and programming. Both vessels strike an optimal balance between modern conveniences and manageable crowd levels, making them ideal for cruisers seeking variety without mega-ship proportions.

Smaller and Classic Vessels: Oriana, Oceana, and Aurora

Oriana (69,153 GT, 1,924 passengers, launched 1995) and Oceana (77,499 GT, 2,016 passengers, launched 2002) represent P&O's classic ocean liner heritage. These mid-sized ships appeal to experienced cruisers valuing elegance, spaciousness, and authentic maritime atmosphere over contemporary technology.

Aurora (76,152 GT, 1,874 passengers, launched 2000) stands as both P&O's smallest and oldest active vessel. Despite her vintage, Aurora undergoes continuous modernization while retaining classic ocean liner grace. Her boutique scale fosters community atmosphere and allows access to smaller, more culturally-rich ports unavailable to mega-ships.

All three vessels excel for cruisers preferring intimate onboard environments and less crowded public spaces.
