Going up south

The diameter of the earth is larger at the equator than from pole to pole.
Thus it could be claimed that when you go south you actually go up. That's
what eh have been doing all day, going south with light winds from the
south. We left this morning at 10 o'clock after taking in 180 liters of
diesel (apprex 43 US gal). We knew we would need a lot of it on our way to
Lisbon where we will refuel again. And we have been motoring all day long.
We should get to Lisbon tomorrow morning at around 8 a.m. Again, we will
have to wait one extra day when more favourable wins are supposed to show
up. Jean-Paul and myself are losing patience with this accumulation of bad
luck with the weather.
