Thinking about it, I dont know why a P class would be in the English Channel. Their itinerary was fixed;
Birkenhead to the Far East, return to Liverpool, discharge, then Glasgow for two weeks discharging and part loading, then Birkenhead to complete loading.
This never changed while I was in the company in the 50s and 60s.
Yes but the four P class vessels were, at the time I was in the company, fixed on that particular itinerary and never deviated from it. You could predict the time of docking at Gladstone Dock homeward, on the day you sailed from Liverpool outward.
