Why is the bridge of an oil tanker at the back of the ship?
It has to do more with visibility. When these ships are in port, the captain or harbor pilot needs to be able to see as much of the ship as once. If he/she has to constantly be looking forward and aft, it would take twice as long to safetly leave/enter the harbor. Also, having all of the fuel resivoirs in one location makes it easier to load/unload. Last but not least, since the engine is in back and is heavier than the rest of the boat, it sits lower in the water and the people riding in that part of the ship don’t have the sea swells as if they were on the bow.
