so peacefull

Maybe portholes on the port side, with some Port wine below decks? Nice.

Or, maybe it's POSH (Port Over, Starboard Home - from when the rich in the early 20th century would travel from the US to Europe and back home. That way the sun wouldn't be shining right in your windows. They would have "posh accomodations"

POSH; the popular notion that the word is an acronym from port out ( ward ), starboard home, said to be the preferred accommodation on ships traveling between England and India, is without foundation.

So the US had nothing to do with the word and the acronym does not exist. Even more mixed up.
