My favourite was Mathura on which I sailed as junior eng in 1970.
I find it difficult to recall all on board but here are some I remember. Chief eng. George Black + wife; 2nd eng Brian Pert; 3rd eng Charlie Drought +wife (Betty); 4th eng Tom Lilley; Chief elec Ted Goodwin. The old man was Captain James, can't remember his first name. The deck officers I can only remember first names, from the chief in descending order they were Derek; jack and Rhys. If anyone reads this who was on the Mathura at that time perhaps they can fill in missing names plus others I have not mentioned.
Cheers, Derek Scothern.
