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

And further, "port" wine is red, and the red beacon light is on the port side of an aeroplane (with the starboard side having green, and white on the tail)

the shorter word:

    port
    left
    red

the longer word;

    starboard
    right
    green

But if you are working with horses or other draft animals, you work them from the "near" (left) side, and not the "off" (right) side. Next up in directions trivia: shotgun, deasil, and widdershins.

This is the same method I use. I always wondered why they didn't use the cardinal directions (north, east, south, west) or why they didn't use the hours of a clock face to indicate direction. With the clock face, you get even more precision where exactly something happened. Man overboard, 4 o'clock!

In my experience with man overboard drills clock faces are used as you describe. Port/starboard is only for low precision things.

That’d be “3 points abaft the starboard beam”

r and s are next to each other, l is closer to p than to anything else.

I always remember the phrase ‘there’s no port left in the bottle’. Similarly, the port-side navigation lights are red, the same colour as port.

It's not true in general that boats always dock on the port side.

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

That'll trip you up if you ever board Tally Ho, her front door is on the starboard[0].

Always? Ferries are boats, demonstrably not true there as they dock both sides.

And "fore" and "aft" are useful to disambiguate the ends of boats that flip 90 degrees in pitch, because the front becomes the top and the back becomes the bottom.

An excellent way to remove unwanted crew members!
