Interesting how it developed into just a way we distinguish today between a motor powered vessel (m.v.)and a steam powered. one. (s.s.).
Logically then, an m.v. should have been,using the original terminology, an m.s.- motor screw-which I think I have seen sometime ,instead of m.v.. Then there's - the RMS Titanic,which you,me and everyone else all thought was Royal Mail Steamship i.e. Royal Mail being a title awarded to a British company entitled to carry the Royal Mail,but now we know it should be Royal Mail Screw Steamer,or RMSS TITANIC in that case ?
Oh dear !, I don't think anyone is now following me! Back to me coffee and 'paper then.
