Zero Six Hotel burns four gallons an hour on average, if that helps 
... during it's fifty nm journey in a no wind situation. ;-)
Actually, the fuel burn is the same whether the wind is blowing or
not.
It's true that with a 20-knot wind the outbound journey will take a
bit longer than the return. (20-knot winds hereabouts almost always
come from the NNW, which is where I am generally going.)
all the best -- Dan Ford
