While talking to someone the subject of fuel usage came up. And the person I was talking to mentioned that the QE2 gets only six inches per gallon. I know this is false and I tell him. He is not convinces. So I explain, at six inches per mile that comes to over 10,500 gallons per mile (actually 10,580 gallons). It is about 3,500 miles from New York to London. So that would require over 35 million gallons of fuel. Even at fifty cents per gallon that comes to over $17,500,000. I donâ€™t know how many people the QE2 holds, but it is less than the 2600 the QM2 holds. At $3,000 per person (I sure the average is less) that is only $7,800,000. That is less than half of the alleged fuel consumption. Simply put the ship gets a lot more than six inches per gallon. I believe the figure is actually about 50 feet per gallon, which is one hundred times better than the alleged figure, bringing the fuel costs down to a more reasonable $175,000.
If I have done all conversions litres/gallon and km/miles/feet correct I think the figures for a 58 000 GRT ferry between Sweden and Finland is about 100 feet per gallon. It is very dependent of speed though - a couple of years ago the crossing took about 15 h in one direction and 17 h in the other (one hour time difference between Sweden and Finland and they had the same departure and arrival times - local time - in both ports) and the difference in fuel consumption was 50% (40 metric tons versus 60 metric tons).
I think your estimation (or was it a scientific calculation maybe?) of 50 feet per gallon is reasonable for a cruise ship.
Interestingly enough, this little baby...
...at 8600 GRT only makes about 90 feet per gallon. She's tiny compared to the big ferries or cruise ships, but speed costs a lot of fuel (she makes 40 knots).
By the way - she is not sinking, just all cars in the forward part have been offloaded. :whistle:
