Was that the vessel he did his cruising on, there was a lady a neighbour of mine who was the personal secretary to the managing director in Ellermans office in Liverpool. She told me that when Sir John sailed he always requested a certain captain to be on board, plus a chief steward also. Where ever they were at the time they had to join the vessel before he did, whether on leave or on another vessel it did not matter they had to make haste to the vessel.
One of my first trips at sea (1962) was on the 'City of Johannesburg' 8207 g.r.t.twin screw Doxford.This was built for Sir John Ellerman for use as his personal yacht but he found it too noisy,hence his switch to City of Oxford a steam turbine.
I believe he had a disabled? friend who used to travel with him.
Quite true Cutsplice, the Old Man was Freddie O'Neill, but I'm unaware of a special C/Steward. He had a blind ex-tory MP friend who often accompanied him as well.
The Officers all had to wear N.10s for tropical uniform when he was onboard, I was led to understand, and also the Mates had to use the outside stairs up to the bridge.
