Mark,
Very little about the subject at hand can be brought up on this web site that we do not know about already. ^_^
Must admit though, it is an awful name.
Keep in mind that Rex is Latin for King, although all ships are referred to as 'shes' (except for the Nazi Bismarck), it still does not appeal to me. White Star had some of the worst names ever. One of my friend's nicknames is Nordic (Say very slowly and with a Teutonic accent). Homeric, Ceramic, Coptic, Vedic, Cymric, Runic and all those other ones were never that nice. As I have said time and time again, how about Heroic?
