If you are conviced (as i am) we're north of the Equator, the risk to find icebergs is higher sending the WB NE than SE.We won't find someone if we end up in a dead-end. That's the whole point I'm trying to make. SE risks a dead end, while NE has practically no risk of a dead end. I don't see what the appeal is of taking an unnecessary risk.
Well, the first warships available in-game are Triremes...
Or i miss something or there's something wrong in your reasonig

BTW a galley can be considered a warship, strictly speaking.
