MV stands for Motor Vessel, just as SS stands for Steam Ship. So in all likelihood MV Alpha Afovos is the same ship as Alpha Afovos.
Afovos is a Greek word (see here)
A picture of the (MV) Alpha Afovos can be found here.
I will have to go back in the thread to see if I can find where the name of the ship boarded first appeared.
The only mention of the ship Alpha Aforovos I can find is the pdf-file you've already posted. Aforovos appears to be a Spanish and/or Portuguese word.
I would have to agree that Alpha Afovos and Alpha Aforovos seem to be two different ships. Wonder if Lloyds Shipping register is open to the public?
I saw a report the ship is named MV Alpha.
