When just floating in middle of the sea, is there any chance i will move? or is it a mod for it maybe? Got the idea when i was looking at a map that shows this current.

It would be incredible slow moving if there was any present....but...just an idea. It could be a lucky break for a unlucky captain. Different thermal layers and all. Wrong place at the wrong time the water current would push the sub upwards to the surface while several destroyers looking for you.
