Usage examples of revs.

These revs seemed about right: White Rover must be doing a bit less than the twelve knots ordered.

The line-abreast formation was levelling up, as some ships cut revs and others increased slightly, to get the kinks out.

So from being the sixth ship in a line-ahead formation, Devon had now to slant out to starboard and become number six in quarter-line, and as the squadron was meanwhile maintaining a speed of advance of twelve knots this involved putting on extra revs at the same time as steering out to the new position.

You could see the revs mounting, in the dials in the front of the bridge.
