> I always have to think about which way is Port and which is Starboard
Port is passed to the left.
Starboard has two Rs, so it's more "Right".
I think the problem on a boat is the "whose left" problem. When person A is facing the stern, talking to person B facing the side of the boat, and they say "Grab that rope on the left", whose left are they talking about? In other words, "left" and "right" are fluffy, unclear, relative terms - "port" and "starboard" are perfectly clear absolute terms.
