We're wasting more turns if SE turns out to be a dead end, which there's a 50/50 chance (I would argue greater) that it will be. Just because we made one poor movement choice doesn't mean that we should make several more bad moves in sequence.
Except there is no indication that there is land that wraps around our south.
There is no possible way that the path north could be a dead end unless there's an iceberg blocking us. And if you're going to argue for that, then it's equally likely there could be an iceberg to the south-east.
If we're in the north, which seems to be the prevailing assuming, the ice will be to the north, not the south. Therefore, it is not equally likely.
Aside from an iceberg, it's simply impossible for the path north to be a dead end, unless the land loops around to the north, then west, and then connects up again to the land we can see to our south. In which case that would put us on an island in the middle of a lake. There is simply no other way in which heading north could possibly lead to a dead end. And given that we can't see any hints of land at all to our north or west, I'm betting that we're not in the middle of a lake, and thus that we will not hit a dead end if we head north-east.
But we can't see any hint of land directly to our south either. So if you're happy to assume that there's no land north, why are you equally happy to assume there is land to the south?
