Readiness often meant keeping boilers running

A follow-up to cold-start timing explains how larger steam warships avoided a completely cold plant when readiness mattered.

Question

Were steam warships normally kept partly powered so they did not have to start from completely cold machinery?

Short answer

Yes. Larger ships commonly kept one or two boilers running to preserve readiness.

Notes

Steam warships were normally kept partly ready rather than allowed to become completely cold. Larger vessels could keep one or two boilers operating so that the plant remained spooled up. This reduced the time needed to move. The price was continued fuel consumption and watchkeeping effort while the ship waited.
