I like this description, but I have always thought that the saying "There is some red port left in the bottle" a much simpler way of remembering the conjunction of these terms. Assuming you are fasting forwards in the boat of course!

They should get rid of these terms, as they are distracting.

A big part of the training material for boating license is about learning things that people are not using in practice, which makes less time / mental power to learn what is really important to survive and avoid crash (what's really important).

Earlier quoted context omitted.

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.

Imagine you are crew, standing on a ship. You are facing east, and the bow of the ship is facing north. It’s night and there is a thick fog.

You hear a cry “man overboard on the left!”

Where is the overboard person? Are they to your left, the ships left, or the left of the person shouting?

If the cry is instead “man overboard on the port side!” there is no question.

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.

Of course, but this article explains what each word means.

Starboard => Means "steering side of the boat" (b/c the oar was on the right side due to sailors mostly being right handed)

Port => The side that faces the port when docked

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.

My shortcut: "port" and "left" have the same number of letters.

It's funny to me that some olaf 1000 years ago just called them what they were; the steering side and the docking side, and now we have to use the same words which don't make any sense to us. I vote we just call them the steering-side and the docking-side again.

Whether "the left" means your left, the ship's left or yet another left (the harbour's?) is highly ambiguous. You can't assume that everyone will instantly understand this correctly.

I think starboard and port make more sense here because they only describe parts of the ship, so the meaning of the terms is completely unambiguous.

"Left" vs "the left" is not good enough. That could still mean either concept semantically, and you can't be sure the person speaking to you didn't mess up the convention when the two are that close.

A crew (any kind of crew) requires exceedingly clear communication. "Ship left" and "ship right" could work, but what if the environment is noisy and you're not sure if the first word was "ship" or something else? Domain-specific, unique terms are fantastic tools for crews.

I understand that the terms are mostly unambiguous, but I always wonder how these get defined in edge cases. For example ferries, at least where I live, alternate the direction of travel as they go back and forth. There isn't a fixed "bow" or "stern" from which to define port and starboard.

This is a great question imo but I struggled to find anything very good. I found a forum post, https://www.sailnet.com/threads/double-ended-ferries-which-e... and between the trolling it seems that fore/aft and port/starboard switch when the direction reverses, including eg navigation lights (red for port, green for starboard). And they tend to also have a one end and a two end or an A/B end, and those labels don’t change.

I’ve always remembered it by “port and left both have 4 letters”. It has always worked for me.
