Frequently Asked Questions
How is the comparison score calculated?
We compute scores across 8 categories using real spec data: gross tonnage, passenger capacity, crew capacity, year built, length, deck count, space ratio, and fleet power. Each category awards one point to the winning ship.
What is the space ratio and why does it matter?
Space ratio is gross tonnage divided by passenger capacity. A higher number means more space per guest. Luxury lines typically score above 40; mass-market ships often fall in the 30-40 range.
What does the passenger-to-crew ratio mean?
Passengers per crew member. Lower is better, more staff per guest means better service. Luxury lines aim below 2:1; large mainstream ships may be 3-4:1.
Are the prices shown accurate?
Prices are sourced from Cruisebound and reflect real-time availability. They may change based on cabin type, date, and demand. Click through to see the latest fares.
