““Port” has four letters and “left” has four letter.”
Hah!. That was the little trick I had to use...when I was in the Navy! The only nautical term I still have firmly implanted in my brain...”the head”.
Port left wine(red).
They all have four letters. It’s how I teach Sea Scouts their left from their right.
Green means ‘go’, and red means ‘stop, your burdened’.
