Step-by-step explanation:
Size Matters
When considering how much fuel it takes to move one these massive vessels, it depends on the size and speed. Liners like the QM2 will need far more fuel than a smaller ship. The concept is similar to land vehicles. Naturally, a small economy car will run longer on less gasoline than a big utility truck. Though cruise ships continue to get bigger, there's always hope for better fuel efficiency.
At full power, they would burn around 1,377 gallons of fuel per hour, or about 66,000 gallons a day of high-polluting diesel fuel.
