Ships Bridge "Fore v/s Aft" why?

[oceanbear]

Hei, you probably had got this question several time before, but now is my time to ask:

What is the different to have a ship bridge Fore vs Aft?. Do you have any scientific argumentation for this solutions?

 

As an example I see that supply boat, military boat, cruise boat, well boats, etc has the bridge Fore. By the other side, I saw also well boats that has the bridge aft?

 

Thanks in advance for your comments.
