Per AI:
Carnival Cruise Line consistently leads in reported crime statistics, including sexual assaults, rapes, and physical assaults with serious injury, holding the top spot for industry-wide crime incidents in Q3 2025 and accounting for 59% of reported physical assaults since 2022. Royal Caribbean also ranks highly in raw crime numbers, leading in Q4 2025 and Q2 2025 for sexual crimes, though per capita rates vary significantly due to its larger passenger volume.
Regarding illness and sanitation, Norwegian Cruise Line ships like the Breakaway and MSC Cruises vessels have frequently appeared on the CDC’s list of the dirtiest ships with scores below 86, facing issues like food infestation, unsafe temperatures, and crew members working while sick. Specific incidents include the Costa Concordia disaster and multiple norovirus outbreaks affecting Princess Cruises and Celebrity Cruises, which have also struggled with inadequate medical facilities and improper body storage.
Maintenance and mechanical failures are frequently cited for NCL (Norwegian Cruise Line), which has reported propulsion issues and unsafe conditions leading to lawsuits, and MSC, which faced a 2019 dock collision in Venice and a failed inspection scoring as low as 67 points in 2024. Holland America and Celebrity have also been noted for outdated safety equipment, inconsistent emergency procedures, and poor outbreak management, with the Zaandam incident in 2020 leaving stranded passengers without proper medical care.
