It has its own terms for a very good reason.
It’s relative to the boat, so that if you are standing on deck and looking back everyone knows what you mean and not if you are talking about your reative left or the boats.
So you just collectively agree that left is the ships left while you’re on the ship.
Problem solved.
The left is always the ship’s left, just like the left side of a car is always the left side of a car.
Except we say drivers/passengers side when referring to the side of a car. People dislike port because they can’t remember it from lack of use. Insecurities cause this whole discussion.
I don’t use it often at all, but when I was 6, I just remembered left/port had 4 letters and haven’t forgotten yet. Some day I might, but me forgetting doesn’t mean I should ask everyone else to stop using language.
E.g. I have a plethora of grapes. We should stop using the term plethora because they could just say “a lot.”
Let’s name them something edgy and disruptive. How about calling all four sides “X”.
All sides should be called Alladeen.
