Okay, this is an academic question, not really one that will help
with the climate-placement goal, but if you were to, say, sail all the
way north and then just as you were about to cross over into the southern
hemisphere you changed directions, let's say made a right turn, where
would you end up? Would it still be in the South Pole region only a
little to the right, or would it be, for instance, somewhere in the
western sea? Additionally... does a compass always point north in this
world such that if you followed it and continued to follow it north you'd
end up on a continuous loop passing over the same landmark over and over?
