Which was the first ocean liner/ cruiser to have 'turbo electric' transmission...
(mixing water and electricity... how clever 
)
BTW... (not part of the Q) but what legislation is there to prevent the name Southampton remaining on the stern? Since it is no longer under British jurisdiction, the good people of Southampton can't do anything about it... Not that they could anyway, since Southampton is not a legal port of registry.

You are not correct when you say that all UK registered ships have Cardiff as their port of registry. The Registrar is in Cardiff but the available ports are:
