This is a great leap forward

Only coal steamers had noticeable smoke plumes, and by day (When most pictures were taken) sometimes convoys reduced speed to make themselves less visible. I have readed however lots of reports from Kaleuns mentioning the very visible smoke plumes over the horizon, so they were certainly a danger for the convoys.
Also, once the steam has reached enough pressure, it gets released with every piston push together with the normal smoke of burning coal through the funnel, thus making it a bit clearer, light grey. Steam ships make therefore more smoke when heating up the steam than once having reached operational pressure.
