what is the port side of a boat
Port and starboard To understand which is which, when a person is facing the bow on a vessel or aircraft, that is, forward towards the direction the vehicle is heading when underway, the port side is the left-hand side and the starboard side is the right-hand side. However, port and starboard never change; they are unambiguous references that are not based on the relative directions of an observer, just like the cardinal directions of east and west don't change no matter the direction a person faces.[2][3]
