I am not specialist for town maps but definitely no red glow. And even in the second one, you could remove the red glow around the numbers. As they are white, they are well visible anyway and I rather felt bothered by the red around.
The first idea I had looking at this map was that these ships were impossible.
Almost all berths in the harbor are occupied.
But the many outgoing ships should have left a free place in the harbor, shouldn't they ?
And as they didn't (why ?) then there is no place for the ingoing vessels either.

Well if there is a harbor master, he should hang
