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.
