Reply #3: actually I can see that one

[nadinbrzezinski]

and I will explain why (though I'd rather have this used by First Responders)

Teh cruise ship is more or less independent from teh grid and the city... so they can more or less work independenty... but a USN Marine Transport ship would serve the same goal and after docking all essencial functions can be done by a skeleton crew with the rest of the crew working in the relief effort

Bot on this one there is actually some logic
