Oh yes, and a spec I should ask about. How many tons of fuel per nautical
mile?

As I posted earlier, approximately 4 nm per ton of fuel oil...

So, assuming 6 lbs per gallon, then we have 4nm per 333.33 gallons, or 83
gallons per nm, or around 72 ft per gallon...


I would suggest taking out that uneffecient old 1940's oil burning
propulsion system and replace it with a nice thermo-nuclear
reactor system.
That way you don't have to refuel every thousand miles and can
easily go 20 years before having to refuel.
