One issue is that while we can rate a good security briefing, and the general physical state and availability of safety measures, few of us are knowledgeable on the actual details. A good example is the height of these boats. They sure as well look unstable to me. But then again, so are modern cruiseships, which are substantially taller relative to their other dimensions. I don't know what makes or breaks such designs (and if Egyptian shipyards cut corners which could make such a design safe(r)).
