ATHENA was the ill-fated STOCKHOLM which collided with the Italian liner ANDREA DORIA in 1956 with the result of her sinking! Very bad story...
In the late 80's was put alongside somewhere in the port of Genoa until some businessmen decided to rebuild her completely converting the ship into a small but refined cruiseship. So she was entered for a couple of years in one of the drydocks of San Giorgio, dismantled and rebuilt on the new design, also new engines were installed and the ship in 1996 was renamed "Italia Prima". She passed in hands various times since that, now it is already many years which is sailing with International Classic Cruises as the "Athena".
For what is regarding the SEA CLOUD she is really one of the oldiest floating ships even if calling her a cruiseship for some aspects is funny...It is very small and "delicate". I manouvred her two or three times and it is not a nice behaviour specially with strong wind...it is better not to use tugs because modern tugs are not the best for her marine equipment layout, bitts, winches...also the crew was not so "nice"...but any way she is an old lady to handle with care...
