From Egypt to Crete by ship?

I am thinking about making this holidays a bit special this year... I got an idea of spending few days in Egypt with a friends and then moving to Crete for the rest of my holidays. Is very easy to fly from Egypt to Crete, but I was thinking more about a ship trip from Alexandria to Chania or Heraklion. Does anyone know where I can get some info about prices, timetables etc?
