Meaning
Easy, unimpeded progress with no significant problems or obstacles.
It’s often used to describe a process after the hardest or most uncertain part is already behind you, as reassurance that what remains should go smoothly.
Origin
The phrase is a literal nautical term, describing a ship traveling across calm water with a steady, favorable wind, requiring no difficult maneuvering or struggle against the elements — the most effortless kind of sea voyage possible. This maritime origin fits into a large family of English idioms borrowed from the age of sail, when seafaring was central to trade, travel, and everyday cultural reference; the figurative sense, applying “smooth sailing” to any easy, trouble-free process on land, developed naturally from this shared nautical vocabulary and is documented in general English usage from the nineteenth century onward.
