Voyages of discovery? (spoilers for all RotE books)

[Farseer]

I was looking for something else altogether and came across this little passage in Ship Of Magic that may be of interest to this thread. Ronica was recalling times when she and Ephron had made plans for what they'd do once their kids were grown and the Vivacia paid for etc. Ephron had once said,'...I've a mind to carry you off with me to the Perfume Isles. Would you fancy that? Twelvemonth of clean salt air and naught to do but be the captain's lady? And then, when we get there...'

From this passage it is possible that southerly travel and discovery has been quite extensive, and for quite a long way south of Bingtown etc if one can travel by liveship for a full year prior to reaching a destination?
