good question. Simple answer. you face downstream, towards the sea. If a boat is navigating downstream (going to the sea) the left bank is on your left or the port side of the vessel. If a boat is navigating upstream (away from the sea) the left bank is on your right or the starboard side of the vessel.

A submarine is a sea going vessel that is designed to run submerged or on the surface of the sea. Basically, by filling ballast tanks with sea water, the submarine will sink, and by blowing out the sea water from the ballast tanks with compressed air, the submarine will float on the surface.
