Leaving Glasgow on the Pacific Reliance, I was senior cadet and on the bridge. During sailing, the Master Captain P F Owens (Uncle Patrick) told me he had had a letter from HO saying that cadets were to go no higher off the deck than the top of mast house. Cleared pilot, full away and "Woodsie go and put up my radio aerial". This entailed tying his aerial to a heaving line, climbing to the table of the mainmast and securing his aerial. LOved it!!
