I should add that the Hylton was not a tramp steamer, but a motor tramp powered by a diesel engine driving a single screw with a service speed of 12 knots. I once sailed in a similar ship, the Richmond Castle, but we were on the general cargo/citrus fruit run out to Souh Africa and back via the Mediterranean. Rather uncomfortable, but happy times with very little stress, as we had no passengers and hardly anything ever broke down.
