ORIGIN

‘Plain sailing’, along with ‘smooth sailing’ and ‘clear sailing’, is a nautical phrase that has the literal meaning of ‘sailing that is easy and uncomplicated’.

All these expressions are now used figuratively to describe any straightforward and trouble-free activity.

There might seem to be be little more to say about ‘plain sailing’, if it weren’t for the existence of the phrase ‘plane sailing’.

‘Plane sailing’ is a simplified form of navigation, in which the surface of the sea is considered to be flat rather than curved, that is, on what mathematicians call a ‘plane surface’.

The plane method of approximation made the calculations of distance much easier than those of ‘Mercator’s sailing’, in which the curvature of the earth was taken into account.

Both spellings “plane” and “plain” have been in use for several centuries.
