This explanation feels kind of awkward. My left hand does not depend on my orientation, so I am unclear why the "left side" of a boat would. I get why there are better terms to use when talking about others. At least, I think I do. But it feels like there is more history to these terms than just "needs to be fixed."

Because "boat left" and "boat right" just didn't catch on.

Because if you face the back of the boat the sides reverse. It’s similar to stage left. When you can’t afford to be confused, one name is better than a conflicting argument between your left and the boats left.

But if I'm looking at you and speak of your left hand, I am not speaking of the hand to my left. Literally nobody does that. At least not on purpose.

The problem is that people (especially in stressful situations when they’re not thinking carefully) will say things like “that one on the left!” and the person they’re talking to (who is often facing them and thus reversed) won’t think to ask “my left or yours?”

But if you train people to use specifically-invented unambiguous terms that can’t be screwed up, their brains will reach for those words when they’re in trouble.

Do you own a car? Commonly when speaking with a mechanic they'll ask questions like Driver's side or Passenger's side to get away from left/right. People very often describe things with just _left_ or just _right_. They don't say things like when I'm sitting in the car the door to my left is hard to open. They just say the left door is broken even when both them and the mechanic are facing the car head on. By having…

You aren't wrong. In that mistakes can be made. But if I ask you about your left hand, is that ambiguous? By your definition here, that is an ambiguous question. But, that just feels wrong.

Edit: I'll note that it is amusing to compare to cars. It seems the etymology of the terms is literally "driver side".

Because you need to differentiate between "my left when facing the boat" and "my left when on the boat facing forward" or really, left from any other perspective.

And any time there's a multi-word phrase like that that gets used a lot over many years, it gets shortened.

Because left and right are ambiguous - are you talking about MY left or the boat’s left? Having unambiguous names let’s us differentiate and avoid confusion. It might be hard to grok the need for this if you’ve never been in a tight spot while sailing or operating a watercraft with a crew - but having this distinction has probably saved thousands of bad incidents from happening.

Yes but why would you ever be talking about your left? Use the definite article, THE left, and it should be clear by convention for the sailors.

I think it's just historical.

The only was I can remember which is port and starboard is by thinking about boarding an airplane. The steps/tunnel are always docked on the 'port' side, just as boats always dock on the port side. The cockpit/bow is always on your left when you board.

I can see it as advantageous. With the major caveat that it is only advantageous to folks that have been taught it. Not shockingly, a large portion of the passengers on a boat are going to be confused if told to go to the starboard windows to see the whales that are beside the boat. How will you explain it? I'm going to guess that you will probably say "right." :D. (Note that this isn't hypothetical. I take a ferry f…

Yes, in that situation, you can confidently tell them to look to their right, because you can assume that most of them will sit in direction of travel and face forward. However, the same is not true for a sailor who might be running around on deck.

Any room for error is a guarantee that a human will mess it up. Left already has a definition, so there's room for confusion; a word specifically talking about the ship is more concise.
