In " Mighty Ships " a US Navy female officer was saying port rather than left, is this a new thing?

Are you serious. For hundreds of years on ships it has been known as Port and Starboard. Where have you been. ?

No - sailors have been using Port for left ever since the rudders were on the right side ("steer" board, or starboard), meaning you had to dock on the left. Call it 2000 years, or more.

The trade I joined in the Canadian Forces had been primarily Navy before integration, so, we had a lot of naval terms in our day to day language. We could live "on board," which was on the base, or "ashore" which was downtown. Our building had "ship power" (our own generators) when "shore power" stopped working. The NCO responsible for assigning cleaning duties to the privates was known as the "buffer." We got the brooms, etc., out of the "bosun's stores." And so on - there are a lot of things like this.

No, this is common place on all ships everywhere since about 1200 AD. Port means left, Starboard means right. It's probably the most well known set of nautical terms, like Stern (back of the ship) and Bow (front part of the ship). It's considered misleading to use the term left and right on a ship or boat.

Even the Royal Navy use "Port & Starboard"

Don't take it too seriously they are from the service crew department on board the ship.... especially those from the Far Asia, they would complain against you in field combat when you just simple pee behind the bushes... for insulting theirs modesty...

She's juz funnin' yew.

Is this a serious question?
