How many days or weeks does it take to sail from the coast of Southern Greece (Athens) to the coast of Turkey? How long does it take to sail from Macedonia to Rhodes?

I ask these questions, because, as an American, my understanding of distance in Europe is not native. I can think in terms of approximate sizes based upon comparisons to places that I have lived, but since I do not live in Europe, I cannot really know what the actual distances are. For example, Arizona, where I reside, is slightly larger than Italy (and Italy has 10 times the population), and Montana, where I have also lived, has about the same land area as Britain (Britain has 60 times the population in that case). It takes me most of a day to drive across either state, but that is useless in allowing me pre-modern transportation estimates. It would likely take me weeks to walk across either state, just as it would to walk across either country that is used in comparison.

So for game comparison, how long does it take to sail (non motorized) across the Aegean Sea that separates Greece and Turkey. One week? Two, Three, More?
